Project Sc12

[Gr4H4m]

great news. good luck you will have to start a project thread.. we love pics around here..:D

[Steve]

Will good to see the bhp on a 1293cc

[apbellamy]

My charger has got through customs. Should arrive tomorrow.

I've been screwed by parcel farce though! They charged me £13.50 for the privilege of paying VAT on it. Bar stewards!

[Gr4H4m]

yep never did look into how you could pay before getting charged to pay by PF... I would think there must be away I think it was £8 last year when I got my stuff. sounds like a cartel...

[apbellamy]

It's here.

[Deano]

I got mine from manchester & it still has all the Mr2 Manifold stuck to it ! it looks tidy

[apbellamy]

I just put 12v accross the clutch and it spinds nice and freely, so I'm happy. Cost a fortune, but that's life. I guess I need to start saving for the kit.

[Deano]

Yeah me too postage from Aus is a killer

[Gr4H4m]

on the road to forced induction I love the sc12 looks so 60's to me.

[TONYELF]

Gr4h4m.I thought you may be interested in the following link. Reckons he has made most of the components himself+mates? AND insurance increase of only £30 !

http://elf-hornet.4forum.biz/projects-f13/my-supercharged-hornet-t90.htm#550r4h4m

[Gr4H4m]

A good attempt from scratch.. I admire people who create from scratch its much more difficult to iron out the problems.

I think my insurance went up £80 from standard with all of the mods but then I tell them about everything, wheels, brakes, etc so its not just for the Charger.

[TONYELF]

Honesty is the best policy where insurance is concerned. They will find the least little excuse not to pay out :eek:

I agree...

[@lex]

hmm..... food for thought.

cheers

[Gr4H4m]

Steve and I have been paying with Mega-jolt today. I have had some running problems and a few visits to A&B which seems to have been fixed byt re-building the carb with New old stock carb.

I still had an issue with the car stalling when stopping the car from high revs like when coming to a junction or roundabout.

After a few runs with steve in the passenger with my laptop seat and me driving. We have set the advance slightly higher at 700 rpm which fingers crossed seems to just catch the car before it stalls.... Defo something you can do with a dizzy...

[Deano]

I wouldnt get that problem as the only time it would be under 8000rpm was when i was parking it up lol:p

Glad you got it sorted

[Gr4H4m]

love to see 8000 rpm idle... :)

[Deano]

Thats about what Mavis was doing on the cattle grid at the start of the orme :D

[Gr4H4m]

Well a bit of an update and quiz..

What different about this carb?
http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/carb1.jpg

also made an all steel jet holder to get rid of that bi-metallic rubbish.
http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/jetholder.jpg



On a side note when was the last time you rebuilt your carb? I have taken three HIF's apart and they needed a good service. The throttle spindles and discs seem ok with hardly any wear but the rubber seals were shot on the spindle. The float needle filter was full of crap and the choke seals were shot.. Also when rebuilding learnt that you must make sure that the float is set at the correct height. With carb upside down and a flat edge across the chamber the cut out in the float should have about 0.5-1mm of space before touching the flat edge... So get them carbs rebuilt...

[apbellamy]

What different about this carb?

It's in pieces??

How can you get away with rebuilding carbs in the house? My other half would go mental...

[Gr4H4m]

it is in bits..but thats not the answer...

Just realised that the jet holder it the pics was the prototype, the one in the carb is better made.... Still hasn't made any difference...

[Deano]

Wonder where the other rivet went :eek:

[Gr4H4m]

it was never in there... :)

I made a new one

[Gr4H4m]

Well been having a few issues with carb backfire when starting the engine.

been scratching my head for ages and I have tried loads of things to help sort it but it keeps coming back. Steve popped around last night and over some coffee and some looking, head scratching we come to the conclusion it must be a head problem.

So the head is with Andy at AW engines, very nice bloke. the exhaust valve seats were worn and the valves arnt seating properly. So I have ordered some new guides and Andy is going to re-cut the valve seats and re-lap the valves.....

super.

[Deano]

When it comes to eingine`s Andy is the man ive never had any problems with his work.

When a new mini engine goes really wrong they send em there to

[Gr4H4m]

Well I think Steve and I had done another first... An Sc12 kit running on a bike carb..

[moddinmad]

good work mate. also found this in miniworld in the add section

http://i5.photobucket.com/albums/y198/moddinmad/GetAttachment.jpg
companys using us in there adds too. :D:D

[Deano]

Thats a great add lol

is the car sorted now ? no banging on start up ?

[Gr4H4m]

no chance been to A&B and got some new jets and the new manifold is getting a little tweek. before I can play with the fueling..

[apbellamy]

Any Pics??

[Gr4H4m]

not yet the manifold is having a ring cut into it so that the hose has something to grip onto.

[markrally73]

good work mate. also found this in miniworld in the add section

The cheeky baskets!!!!
Cashing in on our hard work!!!:eek::eek:

[Gr4H4m]

mmm you should get a cut

[Gr4H4m]

A Bit of a update I have done a bit more work over the last few months:

On the pics above I have fitted a bike carb so I could get rid of the SU. The reason for change was, the Bike carbs are a much more modern version of the SU and come with some advantages, in my setup:

- It was hard to remove the SU from the supercharger, where the bike carb is held on with a jubilee clip, so its off in a couple of mins.
- The bike carb uses a plastic piston not a metal one.
- Interchangeable jets for idle, 1/4 throttle and Full throttle
- No oil to top up or go thin when it heats up
- No bi-metallic strip that changes the mixture when its hot or cold.

I used a minispares vac take-off plate and Ade sorted me out a small inlet manifold adaptor, at 45deg to keep the float bowls level.

I have used the arm from the HIF so that the throttle movement is the same.

This has seemed to make the car much more mixture stable in hot and cold weather so a bit of a result.

The other mod was to the throttle disc, I have added the poppet valve found in the turbo carb, or the range rover. This is a small valve that relieves the pressure when you let your foot off after heavy acceleration. The car would suffer from stalling at junctions, this was finally traced to the car getting too rich when you let your foot off, as you shut the air off the extra vac caused by the SC pulled more fuel, so it would flood the engine. The poppet valve seemed to have solved this as it opens on heavy vac and lets a bit of air in so the fuel can be used, this allows the revs to drop like a N/A engine.

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/DSCF4840.jpg

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/DSCF4841.jpg

To aid in this I have also wired the neg pin of the relay used to turn the SC on to output 1 of the megajolt so that I can control when its switched on and off. The car idle is currently set to 1150-1200rpm and the SC is set to switch on at 1300rpm

[Deano]

got to love abit of poppit valve ;)

[Gr4H4m]

I do mate :)

[superchargedhornet]

Project looks awesome, would bin my eaton anyday for a lovely setup like that.

Keep up the good work.

[Bobogib]

Nice project mate. Just bought myself an SC12 to go on a small bore build i'm doing at the moment.

Few questions. What diameter is the bottom pulley, the part of it that runs the charger belt)?

Did you get any issues with overboost at idle and if so how did you overcome them?

And is it possible to either PM, E-mail me or post a clearer pic of the wiring diagram. Its a bit to blurred to read on my computer.


Saw a Video on you tube of what I oresume is your can on the track at the miniworld action day. Got to say it goes well.

[Gr4H4m]

You dont get boost at idle. It can get very rich on overrun as it pulls fuel as ou snap the throttle shut, hence the poppet valve, but that will depend on the engine as mine pulls a lot of vac, I would guess 998 would be worse than 1275, as they consume more air than the small bore.

I dont know the diameter of the pulley, and its to tight to get a measurement. - Ben might sell you a pulley only not sure.

I dont have a clearer pic of the wiring, thats the only one I have it was a while ago. However when you buy a relay it will also give you the connections if you put that and the diagram on this thread together it will become very clear.

Good luck with your build.

[Gr4H4m]

If you run one of these, remove and throw straight into the bin.

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/filter.jpg

[Gafmo]

whys that..I'v had one on for the last three years now

[Gr4H4m]

it was dissolving and depositing white plastic into the fuel system...

[Deano]

I never use these filters they have caused me all sorts a grief emplodeing & falling apart.

[Gr4H4m]

Hi all just making a note of the Winter Upgrades, so if there are any issues I can trace when I made the change.

- Ported head - Turbo Phil - new guides, stainless race valves, MRA top hats. (33, 27.8 custom exhaust valves) pressed steel rockers, new shaft. 1.43mm to block on ex valve.
- Kent 266.
- Oil temp gauge fitted into oil filter housing
- remove fuel filter.
- recirc valve between SC (PCV). all new piping, pneumatic push fit 5mm fittings.
- new choke spring.
- re-designed throttle springs, and cable mount, shorter cable.
- new rubber hose mount for air sock.
- 2 blade fan, mk3 cowl bottom cut away.
- gear linkage re-shimmed and greased, swapped for low wear parts

higher flatter torque curve - 63 ATW.

[apbellamy]

Have you got a rolling toad graph to show us?

[Gr4H4m]

Hi mate its in the garage will dig it out. however more progress..

State of configuration, To be honest its loads more that this but these are the main steps. :)

Setup1 - 62 ATW - Original Dizzy, SU (0deg), Aldon igniter, std cam.
Setup2 - 58 ATW - MJ, Bike carb - Much more stable fuelling, std cam.
Setup3 - 63 ATW - MJ, Bike carb, 266, Turbo Phil head (Valve sizes the same throughout, however using race valves)
Setup4 - 67 ATW - Setup 3 + MJ+3deg. figures at 5800 and still pulling up, rev limiter 6K, power up through the range, good torque curve.


Looking over all my power figures I was making more power from the dizzy setup. So the map was a bit two conservative, Ade upped it 3 deg across the range and power changed a lot it setup 4

Re-Circ valve changed tonight to a solenoid type, to be activated via MJ on VAC conditions.

I think a stronger bottom end and rev to 6500 I think you could see 70ATW. IMO big power from a 998...

[Deano]

More boost more fuel more revs Thats what you need :p

[ben92]

What sort of total advance are you running under full load should be around 20 degrees I would have though.
This is my ignition map, it is turbo and intercooled but it has more boost and runs 25degrees oh and E85 fuel which helps alot, but is still fairly conservative.

http://img.photobucket.com/albums/v668/ben92/fuelmap.jpg

[Gr4H4m]

well the Lucas 25D had a max advance of 30deg at about 5500-5800 once it was retarded.

Lots of the maps I have found of the Eaton kits seem to run more advance that the turbo maps I have found which doesn't seem normal as the turbo boys have the advantage of an IC to cool the inlet temps.

I dont have the map on this machine.

[kieran]

hi, im a bit of a newbi to all this but is it not possible to superchgarge a 1275, i hope i dont sound stupid. :)

[Gr4H4m]

you can supercharge any engine.

[Deano]

The bigger the more power :D

[Gr4H4m]

I put a new set of stickers on the front of the car from Buckley Tyres. It feels like it has power steering now... I've got a bit of toe out looking at the old stuff.. They were also crumbling and cracking, but they have been on the car for a few years...

[RSP]

Which brand and size did you put on? They are really good at Buckley Tyres. Have taken all our cars there for years.

[Gr4H4m]

I have put 2 165/70R10 Yoko A008. They had to get them in next day.

P.S. They cant get R pattern tyres.

[RSP]

If you do not mend, how much did those bad boys cost?

[Gr4H4m]

49.90 Inc vat, balance and valve

[MrDerrickC]

What grade oil are you using? I am finding my 998cc is running low on oil pressure once it gets up to running temp. Thinking of installing a oil cooler.

[Gr4H4m]

20/50 Millers CTV its the best stuff, it holds together at temp and its available from A&B...

You are best to fit an oil temp sender and see what its getting to.

[MrDerrickC]

Yeah, at the moment I'm am pulling the gearbox apart as 2nd gear syncro is gone. Will put in a oil temp sensor while I'm at it.

What oil pressure are you getting at cold and running temp?

[Gr4H4m]

well I hit 80 deg today on the motorway sustaining 4K measured at the oil filter. Temp drops driving around town. IMO if your going for a cooler you will need a stat or it will be very cold unless your giving it the beans..

pressure 50 idle hot, foot down hot 75 its always been like that for the last 18 years...

I've got the Halfords stuff in as I couldn't get any CTV but now A&B can get it I shall order some more..

[Brumski]

Hey there...
Loving the car - very inspiring...

To the point of 'guess what I've now got sat in a box in my garage waiting to be configured for V'ANimal'...

[Gr4H4m]

I know I saw the post on 16V mini forum ;)

So whats the plan? Blow or suck through setup?

Lets see some pics of the build...

[Deano]

Ive had one packed in me shed for a couple of years now ;)

[Brumski]

I know I saw the post on 16V mini forum ;)

So whats the plan? Blow or suck through setup?

Er... thought #we were talking about cars not my Mrs... ;)


And the SC12 will eventually go on the K head engine in the Van...

The project on 16v forum is the estate I'm working on... this needs to be finished before I start modifying V'ANimal...

[Gr4H4m]

2011 upgrades Shiny inlet and WI port.....

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/wi2.jpg

[apbellamy]

WI? Water Injection? Not NO2?

[Gr4H4m]

Andy, No2 is for cheats :)

[apbellamy]

Nothing wrong with cheating :D

Apart from the obvious, what does the anti stall valve do and how does it work?

[Gr4H4m]

- The second port is fed by a 6mm pneumatic nylon hose to a 12V brass solenoid valve
- From the valve a 6mm pipe is T'd to the boost valve port on the SC to head manifold.
- At 69 kpa the valve is switched open by the megajolt. So at over-run the boost is re-circulated.

now more stalling at when stopping the car. I found that the SC was still drawing fuel out of the carb at over-run. Something your now not going to have to worry about with the "Carb" your thinking of using ;)

[apbellamy]

good skills

[Gr4H4m]

Mini went for the first spin of 2011 tonight.. Fun Fun Fun... Needs a little bit of work at A&B, but that is getting sorted on Sat. winter upgrades look positive.:D

[apbellamy]

Have you got your new wheels on yet? ;)

[Deano]

looking forward to seeing it mate them wheels must look ace:D

[Gr4H4m]

mmm no they are back at Carls for some work after the tyres fitter damaged all 5 !!!! wasn't a happy bunny

[apbellamy]

Oh dear. Tyres went straight on mine, no bother. I was virtually sat on his shoulder while he was fitting them!

[moddinmad]

mmm no they are back at Carls for some work after the tyres fitter damaged all 5 !!!! wasn't a happy bunny


id be livid! hope they buying you a new set!

[Deano]

mmm no they are back at Carls for some work after the tyres fitter damaged all 5 !!!! wasn't a happy bunny

OMG :eek:

[Gr4H4m]

mm I know, I was more is shock that mad. I quietly asked what they were going to do. They have re-imburst me for the repairs, which is 5 new outer rims, and the the time to split and rebuilt them. Needless to say they are not re-installing the tyres, Force racing will do this for me.
To be fair I'm shocked they came to an arrangement so quickly.

gutted they did the damage mate, but fair play to them if they've sorted it out so quickly for you thats gotta be something in their favour :)

Who was it then ??

[Gr4H4m]

you have a sign that was made in the same style.

[charlie_mini]

suprise suprise they scuffed them.... not the best for that sort of thing are they! :)
on the same note tho, again their customer service is pretty good! :)

[Deano]

There a bunch of muppets the messed the wheels & nuts on my berlingo up :mad:

[Gr4H4m]

on a brighter note:
Well 12 months on the Snowdon Scatter is approaching and the winter upgrades have been completed...

Had some setup work at A&B's completed with the simple Water injection system. used a .70 jet and switched the pump and solinoid on at 5PSI. We stuck some temp strips onto the charger and the inlet manifold:

Charger body temp
No-WI = 40C
WI = 34C

Inlet manifold body temp (After Charger)
No WI = 62C!
WI = 45C

I know it would be better to have a temp sender but I dont have a boss in my manifold so the sticky things was the best we could do.

I haven't changed the map advance to take advantage of the inlet temp and I'm using straight water.

A good days work.

[RSP]

Excellent work, better you are well pleased with your winter work.

[Gr4H4m]

Well I went for a spin today with rob and the new drive shaft joints that I put on in jan shattered when pulling away from the lights...... So will go back to the rubber joints rather than the qh roller bearing joints. The parts quality these days just don't sem to be up to the job...

Thank god that it never went on the a55 whe we were doing soem speed

[RSP]

In the words of Graham all I can say is "unbelievable!!!" Shocking how parts are not up to the job these days!!!

I would recommend any mini driver to get themselves covered by the AA, Greenflag or RAC as even when you look after your car and add what the manufactures say are better quality parts, things can and will go wrong.

Hope you are not up to late trying to fix this, especially after fixing the rattle and wobble after first owning the mini.

[Gr4H4m]

Parts already ordered from minispares, going back to h rubber cross joints, I dont think the nylon I man enough fro he job seems too britle

[RSP]

That was quick!! seems to be the case that they are just not up to it and the bits on the Posthouse roundabout are testament to that!!!;)

[Gr4H4m]

Good point rob I have used the RAC twice since 2006 recovering the mini. Both due to a parts failure rather than no / bad maintenance... sometime you just cant stop it...

[Deano]

It seems parts are getting worse & worse :mad:

[Gr4H4m]

Well I'm without the mini for a month.... It's in for paint...

[RSP]

Bet the garage is looking empty!!:(

I am sure it will be worth it in the end, to get a nice shiny new paint job.:)

[Gr4H4m]

Yep had to go out there tonight and it was an initial shock when I opened the door....

[Gr4H4m]

well there is no going back now...

SPIDERS !!! AAAH RUN!

still to be done.
http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/CIMG3191.jpg

hopefully not too many other finds.... Happy with the lack of holes so far.... maybe have spokent too soon but I hope not.

Maybe I should go for the maclaren look and just get it clear coated once all the paint it off....?

[RSP]

Looks like they are doing a good job there mate. Should be mint when it comes back. Can't wait to see it.:D

[RSP]

So mate, how are things going with the resto? Bet you can't wait to get him back in the garage.

[Gr4H4m]

maybe this week maybe next..dont want to rush them. but would like it for the actionday..

[RSP]

You are very wise, it is ready when it is ready. Fingers crossed for the action day.

[Gr4H4m]

Well I got away from work early today, jumped on a train and have the car back... next stop off to the track....

[RSP]

Sweet mate!!!Can't wait to see this bad boy again. Enjoy the track

[Gr4H4m]

Well firstly a big thanks to colin (Sprocket) for lending me his block testing kit...

It went like this.. yellow means combustion gass in the coolant. (funny thing is the car was running great but the idle was crap)

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/miniheadgasket002.jpg

So I pulle the head off which is a PIA on my little engine.

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/miniheadgasket007.jpg

http://i132.photobucket.com/albums/q18/Mini_Addicts_Gr4H4m/miniheadgasket003.jpg

looks like it didnt seal correctly?

[English Bully]

lol,seen a few like that in past
I bet she was getting a tad warmer aswell as ****y idle ??

[Gr4H4m]

I was having an issue with heat. Bu the two fans and the two core were doing a good job. But I I was loosing coolant and it was a becoming difficult to start.

However it still went well.


Anyway a new performance gasket is on the way and a new stud kit as the old one had some damage to the treads.

[Gr4H4m]

Oh ps I think it's a clamping issue but we will see

[RSP]

Good work mate, a knew you could have that sorted:). Are you going to fettle it a little before putting it all back together;);)? Add a few more BHP's?:D

[Gr4H4m]

No I don't think so I have limited options on that front. I going to try and stop the oil leak.........

[Gr4H4m]

well its all back together, changed the gear linkage seal, tappet cover seals and the trusty head gasket.. wacked in one of those new minispares head gaskets from AUS they recon it comes with a 100k or 3 year warrenty.... we will see


some ruel of 9 to do any it should be ready for a test...

[Gr4H4m]

Also notices that Bukley tyres never did the rear radius arms up after adjusting the camber.... not good. lucky I checked.

[Gr4H4m]

Well it starts.... got to give it some around the block action with the old wide band to check eveything is ok for the scatter...

[Gr4H4m]

Got to one the sound of boost....the car has had a quick spin around the block and feels good..... Can't wait for the scatter!

[RSP]

Happy days. Can't wait to do the scatter with all of this years mods. Happy days

[Gr4H4m]

well today I mostly avioded turning the car into a bomb... The outlet on the tank had cracked and was leaking fuel into the boot... It must of become damaged during the respray...

Anyhow the car is now running is short range sprint tank :)

Started the scatter shake down, got to say I do love BOOOOSSSTTTT

[RSP]

Holy smoke!!! that was a close one mate, How many miles do you get out of the sprint tank? Scatter shake down here we come!!!

[Gr4H4m]

I cant remember TBH.. On the old motorway the larger tank was only about 120miles before I started to worry... But the car does much better on the lanes. I will have to drive faster to make sure we can make a petrol stop :)

[Gr4H4m]

Well had the idle tweaked to today by AB everything seems to be running great. Ready for a bit of a run tomorrow to make sure everything is ready for the Snowdon scatter
