New PBs: 13.8, 104.95mph
Had an interesting day today.
First, after driving for about 1 hour 15 minutes to get to the track, i noticed the supercharger sounded like crap. Sounds like bearings
. Checked everything over, and decided that it would be a great time to change my oil really quick because its been awhile and My oil was nasty, so i figured fresh oil flowing could help the sound, maybe something was gunked up. So i did that. It got better. But anyways, the sound still remains. But sometimes it gets better, and sometimes sounds worse, its random. Any thoughts? It happened pretty suddenly. 
Second thought, i tightened the belt some more, i thought maybe i was experiencing belt slip because i only hit 9.5 psi on a 2.87 pulley. This was before leaving for the track. Maybe i tightened too much? Leading to this bearing noise somehow? After the night was over i realized it hits 13 psi now. So im happy about that, but worried about the sound.
DEK, rod removed, 5 speed
V2 w/ 2.87 pulley
440s, z32 maf
Ypipe, test pipe, catback
EU, partially tuned, basically i know down low its rich, and im not sure exactly how its going up high now, especially with the added 4psi i gained today. my LC1 gauge is giving me E4 right now
Street Tires Best ET:
60 ft: 2.4
1/8: 9.393
mph: 81.96
1/4: 14.159
mph: 103.80
Street Tires Best mph:
60 ft: 2.667
1/8: 9.713
mph: 82.78
1/4: 14.423
mph: 104.95
Im having an incredibly hard time getting a good launch with street tires as you can see
So i threw on some slicks for the first time ever. i was scared as crap lol. I launched like a sissy, i was basically surprised and not ready to go full throttle. didnt know how soon it would hook, now i know. And i missed 3rd....
60ft:2.089
1/8: 8.98
mph: 80.00
1/4: 13.804
mph: 102.50
I tried to run again on the slicks, i wasnt scared anymore, and i had a plan in my mind, but the darn slicks arent holding air. so i had to go back to street tires.
So today, my s/c sounds like crap, but makes more boost now. Im mind boggled on the sound it makes. Had an ok trap. really wanted 13s on street tires. Need to tune badly, and see whats up with these slicks so i can run some better times. i feel ok about today, with a tune, a better 60 foot on slicks, and not missing any gears i think itll run a decent time.

I think this car should be putting down better times.
Figure out whats up with the slicks and launch really high.
I can launch at redline with my car.
You are trapping the same as my car, so low 13s are theoretically possible.
Good luck with the car man.
