Hit Richmond Dragway last night with a group of V6 owners who hang out in the Virginia forum. Track conditions weren't all that great--hot, humid weather and my engine was at 210 degrees for almost every run. I knew the times wouldn't be very impressive but rather than just not race until the current issues are fixed I said f it and ran anyway. Got 6 runs in, could have done a lot more but there wasn't much of a point as the car wasn't exactly running top-notch.
We re-installed the supercharger the week after AIS but were missing some parts. The "15 psi" pulley is on but we had cannibalized some parts over the winter to put on Pathogen. We made do with what we had but apparently that didn't work. The new pulley is smaller than the old one so we needed a shorter belt... but we weren't sure how much shorter, so we guessed. Guessed wrong... belt's slipping. What's worse, there's a loud WOOSH sound anytime I hit throttle. There's an air leak in the intake somewhere, probably a result of ghetto parts holding the intake pipes together. I only saw 5 psi in second gear on the first run, 4 psi in third gear, and in following runs the boost dropped to 2 psi and finally 0. I blew out the intake pipes several times resulting in times ranging from 15.5 to 16.9.
NA at AIS ran a best of 15.4, now at 4-5 psi best was the first run: (all on street tires)
RT .3786 (asleep)
60: 2.1529
1/8 ET: 9.3955
1/8 mph: 75.43
1/4 ET: 14.5294
1/4 mph: 95.81
We're going to replace all of the rubber connectors on the intake pipes in the following week as well as get a smaller belt.
Other than the boost pressure drop the car ran fine... I swear its saving itself for James. ;)
Overall I'm not that disappointed, a full 1 second ET drop on 4 psi with a slipping belt and an air leak isn't all that bad. We'll see what happens the next time around in 2 weeks or so.
