ASP Pullys

[240SXer]

I just installed a new ASP underdrive pully and a new front main oil seal. I saw a decent increase with the pully. The only think I have done is the lower 1/2 of my airbox removed, ApexDual N1 exaust, and now the pully. At least on the gtech, my "fastest" time previously was 15.47 now it was 15.30. I know Gtech is wrong (I never run that fast at the track). But those are my 'best' gtech times. So i'm sure it shows at least a .1-.2 gain in the 1/4 mi. Anyone who was thinking about getting it, it's good. The ASP does not underdrive the AC, just everythng else. I did notice the engine struggles a little bit more with the electric fan and the light and speakers on at idle, but it's nothing horrible. I'm not idling too much anyway
