Yup, wasn't content on just drag racing, had to strap it to a dyno.
Anybody ever wondered what happens to a 2.0l when on the dyno doing a pull at 16-17psi and something lets loose in the drivetrain at 4200rpm so it shoots past 7200 rpm (as recorded on the datalog, the dyno sensed a problem and stopped logging alittle after 4200rpm) and sustains WOT for 4-6 seconds after going past 7200rpm(God only knows how high it actually went, 8k, 8.5k etc.? Then it was abruptly let completely off...)).
Well, let me tell you. Bad mojo. Shattered plug, piston rings shattered, turbo fubar'd. etc.
Was on a quasi decent pull, the dyno recorded 262whp by 3300rpm then all hell broke loose and dyno operator didn't catch it too quick. Not sure what let loose in the drivetrain, lsd? clutch? 3rd. gear? who knows.
What I want to know is what the hell happened to the rev limiter? I can't say I ever tried to hit it, but does the MPI take it out? Did this happen to quick for the pcm to respond?
Then it was a 122mile tow home. All I can say is thank God for AAA+.
I shoulda just stuck with the track .........
