Sc12 Supercharged Small Bore - Teeth in the oil
Turbo Mini Forums

this made me laugh out loud !!! thank you graham.



I wonder if there could be a stickied ''prime thumbage'' section ,for thumbs up shots and vids ? I really enjoyed andy's synchronised thumbing as well.

re the carb fuel supply , graham , when i ran the single carb on the suck through 400/4 bike , I connected a pipe from the float bowl drain to a bit of brake pipe stuck into the air flow about 3/4 of the way up the carb mouth ...then crimped the pipe to get the mix right .it would only draw ,bit like a spray gun ,when the flow was fast enough .
also , to get enough fuel into the float bowl ,on te tvr I ran a separate feed directly into the carb ,and this was switched on at 10 psi boost .

Robert a bit like a thunder jet?

I run a supercharger and I don't care the TB is on the wrong side.

rushes to look up thunder jet on guggle...

yes just like that .

Well I found Mikuni make an extra jet, so I have ordered one and wil have to brave driling some holes in my new carb...

Minispares have delivered the new gaskets and bits so I can start putting the car back together.

Then hopefully the bits from the US will be here and I can mod and replace the carb parts and give the car another go on the rollers...

Well after some long thinking... I'm going to use an "electronic" carb....

And use the sc components setup, the same as Andy.

So need to run some fuel lines, pump in an mpi tank and bolt the kit on.....

Then sell all of the stuff I have left over to get some pennies back...

Welcome to the 21st century

Class C 3rd Place Avon 2011 14.18 @101mph

Ok chaps could do with some help.

I have had a search but either couldn't find it or in the case of the return Line wanted to check if this is still the best way to do it.

When running the injections lines under the car, is drilling and riveting them with some p clips the best option, I guess this leaves you with a few little nipples on the floor pan?

Anyone know the torque setting for the hols that hold the mpi pump in?

What fuel hoses do you use? Teflon lined?

Are an fittings best to pass the hose through the boot floor?

How did you run the wiring to the fuel pump? Can you buy the mpi pump connector.

How did you flare the pipe under the car? Use a brake kit but just put a small flare in?

Just getting stuff ready for when the kit arrives.

Sorry for all the questions.

Pump - fully tight.
pump connector - pm me your address and I’ll chuck one in the post.
pump wiring - with a relay and the ecu managing the negative side of the switch.
fuel hose - standard rubber efi hose. Rubber grommets through the boot floor.
fuel lines - either swage a bit with a brake tool or solder on straight fittings with a ridge in them.

Andy thanks just seen your reply the solder fittings are genius...

Checking I'm on the right lines, I have put the figures into an Internet cr checker, but I wanted the make sure it was correct as I was thinking of switching to a cometic head gasket, to sort my cr out.

998 + 0.080
Bore 2.60"
Stroke 3.00"
Head 25cc
Cometic c4145-080
Gasket bore 2.65"
Gasket thickness .080"
Piston deck height -0.010 (no dish in the pistons flat tops)

Gives me 8.88:1?

Just wanted to check before chucking a load of cash on a fancy gasket...

Well I have run the lines under the car and secured with some pclips. I have put the moi tank in, throttle body on.

I need to run the fuel hoses in the engine bay and stick the fpr in a hole somewhere.

Stick the wiring in and see if I can get it mapped...

I do have a load of bits to sell, megajolt, new trigger wheel and rev counter shift light, low pressure pump.

Drill holes in the floor was not a pleasant experience...

Well all of the injection kit is fitted, and wired up.

This time the sc clutch is just set to kick in when you turn the key.

Had some issues with the map setup, wide band and cooling fan settings. It appears that they are not defaulted the correct settings in the software from the factory, and the instructions don't list the wiring when using the sc mini 5 port loom, but an email to sc and Simon answered this evening so great service.

Like all things you just need to get you head Around how the developer has created the software interface.

Andy has kindly sent me a map to help as well, so big thanks.

I will give it another go when it's not too dark to wake the neighbours up...

Also wired in a knock sensor , was thinking its a good idea....

Booked into my rolling road on the 29th so I've got to get it running enough so I can limp it down the road...

Best of luck Graham. It's coming together.

In the 13's at last!.. Just

looking forward to hearing the results

Well despite all sorts of me knobbing about with the map the car runs like a dog.

The wide and sensor doesn't seem to be recording much... The voltage stays at 4.94-4.95 but the car smells very rich and bogging down. I should have stuck my standalone wide and up the pipe to see what was going on.

There are so many parameters that can effect the timing and fuel, that are contained in different tables I found it very hard to know what was going on.

As the wide band reading seems to be a bit off I can't use any wort of close loop the help fix itself so I can get to the rollers next weekend.

I rang my tuner and confessed its all over the place, so it looks like a tow to the rollers next weekend...

I just hope it's nothing fundamental and end up wasting the time on the rollers!

Time will tell now.

Chin up duck, it'll get sorted.

You need to change your signature

Are you starting with your base map from previous setup for the ignition? Because that is a start, I'm sure paul s maybe abke to help with something just to get her going? Or possibly matty as he is quite good at it iirc.

Or a standard mpi map if there is one about?

Searching is all you need on TurboMinis

Ive tried using the std mpi map but it's just all over the place I find myself going arround in circles. Still some tow rope and hopefully next Saturday someone smarter than me will sort it... I didn't think it would be this complicated...

Ok so after a tow to the rolling road, we got started on the car.

We spent some time, well when I say we... I mean the Ade the local rolling road operator..

So "we" spent some time setting the idle and getting it nice and smooth, this involved some learning of the software interface which is a little 80's and not that easy to work.
"we" set the target idle factors, check the tps, throttle stop, etc. We set the fpr, note to anyone using the sc fpr the instructions are back to front.

The main fuse then blew when the fan tried to kick in. I replaced the fuse as it was too low rated. Went to start the car and nothing. Now at this point everything went a little mad, we couldn't get the car to start at all, and 4 hours slipped by, a new set of plugs and all sorts of stuff, it was pumping fuel out when the engine was stalled, jsut all crazy stuff

We can now only put this down to a corruption when the fan took the power out. Reflashing the ecu with the base map and starting again got the car up and runningt crazy and kinda stopped us doing the fine tuning after maping but anyway...

Ade got the car on the rollers, and some mapping witchcraft was preformed.

Now this is a home built engine and my first one...the car produced a whopping 90 bananas at the wheels.. Not bad for a small bore!

The car appears to loose the crank signal for a split second whilst idling everything drops and then comes back. SO I have emailed SC but It could be the crank sensor gap?

Issues to sort in the new year.

Throttle cable sticking
check the crank sensor distance
Set the knock sensor
We couldn't get the wide and sensor to work, it shows voltage but never fluctuates, I'm going to remove it and send it back, to see if sc can find a fault with it.


The map will then need some fine tuning

The hp was still climbing at 7000rpm but we decided that was enough after all it's a home brew and no race built engine...

Very very happy, overall the kit is good but a bit clunky if im honest...

oh dear, why is is that that thumb makes me laugh !

anyrdup , well done graham after so many setbacks ,90 bhp @ wheels should be around 110 at crank , so bloody good for first tune .

Good skills, sounds nice and cracking power for a basic tune. It certainly makes me feel optimistic about mine.

It should do Andy, this is my first engine build you should see some good power. Cant wait to see what you get.

Robert - Thanks it sees very quick for a little car it really picks up!. It needs some work on the cruse but then we did get a 4.5 hour set-back. So a job for the new year.
The motor does love to rev and that re13T SC cam works very well. I think its about the sweet spot for the confguration.

The injection does make it drive very differently the pickup is much better. Its never idled so steady and smooth.

Loving it...

How's Ade doing graham? Me and Ben are hoping to pop and see him, get our cars dyno'd and given a once over, hopefully mine one wheelspin on crappy tyres this time lol
