Re: 2006 Noble M400 #141

Well, it's been a year since I've driven the car, and I had zero time last year, so I sent it off to Ohio to get fixed. Just before the motor popped it started making boost, and the shop found rock pieces embedded in the pistons, and one compressor wheel had a couple nicks. So it looks like a rock or two must have lodged itself in the compressor causing it to not spin, thus the no boost, then broke free and toasted the motor.

Car now has a brand new motor and 1 new turbo, and went to the dyno today for a tune. One of the turbos seems to be not opening the wastegate, it's making too much boost so it'll be another week or two before it hits the dyno again. But this is the dyno graph from the only run (no tuning), it's a little lean but had zero knock at 25psi and 12.5:1 AFR, good sign that it should be a very reliable setup when it's back down to 16 or 17psi and 11.5:1 AFR.

Shootout (dynojet) numbers are 678hp/601tq. That's way too much for a street car that weighs 2400lbs (I'd never get traction), so he's going to shoot for 550whp at 16psi.
