Well its been 2 years and 6 months since the engine was rebuilt and mapped, and i finally got round to the rollers!
1st run it spun straight away
2nd run took it to around 7000rpm with 2 guys stood on the door sills it made 171.3bhp & 136.3lbf ft torque, believe it was still slipping as torque should be higher
He said could it go more and i said it had a few rpms left so on the 3rd run around 7300 rpm it made slightly less bhp but oil temp had increased from 80 c to 95c and water temp had gone from 70 c to 90 c think the heat had a slight affect.
All in all i guessed 172bhp and weren't far off and happy with what i got. Hopefully get it done again with some more weight on the front end not half way down the car.
Still need to fit the PPP mani as well.
