It's made about 125hp at the wheels, which equates to about 150 at the fly according to the calculations. The exhintake cam (higher duration exhaust cam) has been ditched due to tuning issues which resulted in increased performance. Although compared to last time it was on the dyno it's only found 4hp at the top end, it's gained about 20-30Nm of torque throughout the rev range which is pretty massive considering the % gain, and the tuner said it's a lot nicer in the midrange now.
Current issues, the brakes are doing nothing, so they're going to try switching out the old Carbotechs for some new standard pads and we'll see if they sort the issue.
The standard exhaust is currently knocking on the driveshaft so that's been jubilee clipped out of the way(!), there's a problem with the throttle cable, this was also there last time and I know how to fix it so that's OK, and the tuner also says it's popping and banging like an absolute motherfucker on overrun which he can't find a reason for, but he said if I can live with it, then fine.
So I'm going down tomorrow to pick it up, and as long as the brake issue can be fixed with any assistance from me if required, I'll be driving it home.
Not really, it's a thread with a lot of words and me posting updates and thoughts but there's no pics other than the 2 or 3 I put on here because I haven't done the work (shameful) and the guys at the garage don't take enough pics for me.
C&Pd mostly from the MX5 forum...
