Hi

Thought this might be of interest to a few of you. Usually setup and test large diesel engines but this came through the door last week.. Mapping for a rally car, we do the setup and run in and a motorsport company come and do the mapping..

240 Crank HP on a standard engine, next stage is a set of Schrick cams, then who knows...







Will post the results when they are in.

Theres something wrong with it, it's missing 2 cylinders.!

I'd love to know more! Do you just bolt the engine up to a big electric motor and spin it round at maximum revs?

Its not for Chris Harris' E30 M3 rally car is it?

Its bolted to an eddy current dynamometer, basically it controls the speed by providing an opposing force; so you hold the engine at 3000rpm and alter the throttle position which enables the engine to be mapped; ie change the fuel, ignition, etc... I make the frames and run the dynamometers whilst in this case Phil from GG motorsport is doing the mapping. It then can be run against a transient dynamometer or rolling road to set the transient sections, ie when running through the rpm at differing throttle loads. There is a good article on both mapping and dynamometers on Wikipedia which is far better than my piss poor explaination.

Yes it is Chris Harris's engine for his car, the guy doing the mapping is a good custmer of ours. Should be interesting to see it work....

Thanks

Chris

I saw the M3 myself recently, it's going to be a hell of a car when it's finished. Will you be videoing the engine on the dyno?
