Well today was interesting to say the least. Since last year, I added a 4lb lower, GT pumps, and a small shot to my car. Last year after a tune, my car put ~481/461. (I have not used the nitrous yet).
Today, the car was being retuned by Bob Kurgan on a dynojet. He tried many different things, but the car just would not put out more than 480 rwhp. Everybody elses car was showing very significant gains. This should be around a 520 rwhp combo, especially with todays cool outside air.
When he looked into it a little more, the RPM/gear ratio was showing that my clutch may be slipping. The power band for the RPM/gear ratio was a dome shape, dropping off the power.
He said as the car wound out, the clutch pedal was sucked down almost all the way to the floor by the end of the run. My Spec 3+ has less than 2000 miles on it.
Going off the datalog, the car is pulling in tons of air, 17 PSI strong all the way through, fuel is proper, but it isn't putting the power to the wheels.
Here is the weird part. On the street, the car feels like a new animal and I cannot detect the clutch slipping whatsoever.
I know the dyno is just a big number-maker, but it still tells me something significant could be wrong with my car.
Anybody have any ideas?? This thing has so much potential!
