Turbo Mini Forums

Spent this morning at the rolling road.

Apart from a minor mishap went the car decided to jump off, everything went great.

For those that dont know, I've just built this engine and set it up roughly to run it in, this is the ifrst time its been rollered properly.

Went in with 120 bhp as seen below




After a few tweaks, got a nice curve all the way up to 140
The black lines were the final run......




Can't wait till I get a new head on it and a little more boost.

Looks brill mate, what engine spec is that from?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

1293
forged pistons
8-1 cr
t2 turbo
mirage manifolds
megajolt
cosworth cooler
phase 2 cam
standard head

10 psi on the last run

Excellent result!

That looks good.
I will need to get on a dyno some day.

Good one. You must be pretty happy with that!

But why is the bottom one in road speed???? And why does the lines not cross at the right point in the top graph? It looks like the 'final' lines in the bottom graph probably do though...

All in all - good result though.

where was that done?

Looks a very impressive result, well done.

nice one, yes where was that at?

quick question on the final graph, why is there a blip at the end?

Fantastic result though, 140bananas for 10psi :o

I've seen the future and tbh its Pie

Not bad at all!

JF.

He did graphs against rpm and mph, just happens thats the one he printed I think.

It was done at Collins Motoring Services in Erdington Birmingham.

i think the blip at the end may have been when it hit the limiter, not sure though.

Im over the moon, it drives like a dream, no coughs farts or anything, so smooth through the range.

If anyone is thinking about mapped ignition, all I can say is do it, you will not be dissapointed.

Cheers for the comments guys

place a well thought out race head on there

roller it again.

you will be so suprised

Excellent to say the least

thats the plan Benross, anyone recommend the best valve size to move up to?

Well, If i can add something in here...
I'd stick with your 140 hp / lb-ft powerplant as is for the time being. It's more than you're accustomed to in a mini - and more than your mini itself is accustomed to. You'll know when the time is right, but i suspect it isn't yet...

Oh I know that Dave, its plenty to entertain me for now, but I always like to plan ahead and get as much info as possible, thats how I got this far

Hi,
Congrats on your new baby! LOL. Can you post up or PM details of the place, as it's in my area?
Cheers,
Gavin :)
