My rolling road graph - T4

Hi Just had my T4 on a rolling road. Does anyone know if the torque should drop like that, or is there something wrong? I'm pleased with the max torque figure, but not sure about where 8 bhp has gone! Cheers :)

I never trust rolling roads. Too much depends on the individual RR, the air tempreture, the operator etc etc. I dont beleive either that the power put down on the rollers will ever be close to the mark. How can a big fan stuck in front of the bumper ever replicate the forces involved and air pressure created at say 140mph?

Did they look at your boost at all?

Hi, Is it a standard car? if so then it's bang on what it should be for torque and a bit over on bhp. i think me graphs looked much the same when i started out although the car wasn't standard even then. i'll look them out for you. Jacq.

Yeah, bog standard :) Glad to hear that it seems about right - Cheers!
