Cossie put on RR

Points

Car
Sierra RS Cosworth
The engine is a 2.15 litre YB in a Sierra rather fun to drive ;)

Well we tried hard to hold these huge figures but flat lined at 800bhp looks a strange graph :bigsmile:. It made 838bhp/666ft-lb on the Dyno but its got a new turbo that would give around 40bhp more. Will be going back on Sunday with wider tyres but its difficult to strap a rwd car with this much Power. Full boost (2.8bar) is at 5k in the car but different loading makes it later on the RR.

Those are very impressive figures. I bet I get better figure for......
......mpg than you! :toung:


You dont know how true that is :confused:

During testing at Brunters recently we measured the mpg & at full throttle it was 2.7mpg :sad2:. This was on race fuel at £24 a gallon :mad:.
 
Hells bells, Gran Tourismo numbers there! Impressive figures, is that the BP102 or better stuff?


Its 106ron.
The Power is ignition limited to stop head gasket failure if or when this problem is solved it can take another 8deg ignition on 120 ron that would push power well beyond 900bhp. At the mo anything beyond 850bhp is not possible on a sustained basis.
