The better way to have a lot of torque

[mark shead]

It would prob be 580 on the rollers through so not all that damp

It would be interesting to see yours on a Rr to be able to compare to your dyno. On the Rr we use its very close normaly within a few %. But it does depend on who and how they run it.

Take some photos .

That's the thing I won't let anyone see it but as far as I know no one has tried or made the same.

Good luck with it - I really am looking forward to seeing Rod's car actually running again after all this time . Would be good to see his top speed figure raised yet again .

That's if we can keep it together for long enough. At this level you can only call it a hand grenade engine if we are running at 1000hp. 800hp seems to last well.

It's easy but what spec do you have or are you after a change of spec.

Hi Mark.
Well, I have a SmallTurbo Escort with stock engine.
I will use, to tune my engine, the original cranckshaft,
new H-section rods, new 8,5:1 cr pistons with valve cuts,
new cams and machined head.
For engine management, I bought in 2011 this ECU:

I hope this is the good to have a good engine.

Did a track day on Sunday and the transmission started making a funny noise......

Turned out that the front diff CWP was the part that finally gave up the ghost. A bit of a wounder, as it is an uprated 7" R&D item (up from the standard weedy 6½ one). Oh well, that is the problem with having 505lb ft of torque . It's done well to last 5 years with the abuse it gets .


And this is NEVER EVER launched - you lot with more, obviously aren't trying hard enough .

[cossyking]

whats it at the wheels Mark?

Thats what it made on the rolling rd when we mapped it

Mike,

Its lasted very well then and cheaper to sort than an FFD etc

Fuck you must know your way round these engines to get that figure

Then,
I have ergal cams pulley, front Quaife diff. in Quaife case
and rebuild (stronger and short gear) gearbox.

I've already broke the original CWP on a Quaife diff before I got the R&D LOL.




I would reiterate that I am VERY transmission friendly as well (my clutches usually last 15k), having NEVER launched the car even back then.

[Karlheinz]

So,
the Quaife diff is not good for high torque?

What sort of speed is Rod going for now? Good to see a cossie hitting the 200 mph

The diff is fine - it is the CWPs that break....

Over 210mph.
