I made it to the dyno today at SRC Racing.... it did not go as planned. My tuner put a new map sensor on, and started doing pulls. The car kept breaking up at high rpms. He got the a/f really nice but it kept breaking up at the same spot. We eventually figured out that it was ignition related
so that pretty much ended it for the day.
The problem is that I need a new rotor and the plastic shroud that goes behind the rotor. The screw on the rotor is stripped badly and the rotor is real old. The plastic piece that goes behind the rotor is missing. The tuner said hes seen this before when adding boost, where the ignition starts cutting if this piece is missing. Apparently its some sort of buffer for the wiring inside the dizzy. So its not that big of a deal, Im gunna get new plugs, cap, rotor and it should be fine. I may have to drill the rotor screw out, but oh well. Mostly Im just bummed because we didnt get to see any real numbers, or use the 110 octane race gas I brought.
The only good things i can take away from today, are that my idle is better, and that its tuned to run on 10 psi now. It made 240whp and 180ft/lbs today, and that was only at 6800-7000 rpms (where it started breaking up real bad every time). After looking at all the dyno graphs today we are thinking it should make about 260whp and 200lbft of torque on pump gas once i get the ignition problem solved. peak power was just over 8k rpms on the 7psi tune, and should be pretty much the same now.
heres a couple pics on the dyno
sorry its not a great vid, it was so damn loud! the supercharger screams sooo high pitched. it was was just too loud and the mic on the camera apparently sucks. the car was breaking up and he let off a little early. I would have taken more and hopefully better videos, but since the car wasnt running right it wasnt worth it.
heres a misc. picture i took today, just because this viper in the parking lot looked so damn mean
