Bob Rawle consistently maps P1's/v5 STi to circa 400bhp/375ftlbs at 1.45bar.

This is a before, & after "Road Dyno" graph showing the VF28 v MD321H, P1, same car, Bob Rawle mapped, same stretch of road.

The same car then made 408bhp/382ftlbs on DSA's Dyno Dynamics rolling road.

 

Mine mapped buy JGM on a safe map, could have gone further made 396bhp with 374lbs/ft at Surrey rolling road

makes 1.5 on the rollers but 1.7 on the road

 

Thanks for that
have to say very impressive, looks like i will be saving some penny over the next few months then, and then yet another visit to Mr Rawle

 

3rd gear run on an RA box.. should have used 4th

although that would screw the history of runs you have as you have altered the car as it has always been run in 3rd.
