Had my car on the rollers today for a power run. Results were not what I expected. (Not saying in a good way or bad way)

My spec is.....

2wd Saff.
Standard comp.
BD10s.
Double valve springs.
Ported & polished head.
803 injectors.
3 bar map sensor.
T34 .55 with 360 bearing and cut back blades.
4x4 intercooler.
22psi peak.
20psi held.

Car was rollered in 3rd gear. I always thought 4th was the gear to use?

Anyway your opinions and guesses please....

Ill post my results later.

Cheers, Ian.
