Woot, new best today at the track. The cooler weather is really helping. The car is an 87 Regal with 123,000 miles. Here's the list of mods, if I don't mention it, it is factory stock from 1987:
-Walbro fuel pump, stock wiring
-DIY adjustable waste gate rod
-RJC boost controller and power plate
-Straight pipe in place of catalytic converter
-110 octane
-About 17 PSI
-275 BFG radial TA's in the back
-Kenne Bell Hi-Lo chip from 1988, lol
Second pass of the night was the best, here it is:
60 foot- 1.8793
1/8- 8.477 @ 81.07
1/4- 13.313 @ 101.26
I am happy as can be with the times. This is all with the stock 123K valve springs, injectors, MAF sensor, timing set, everything.
I tried turning up the boost hoping for a 12 second ET, but it started to detonate a bit so I backed the boost back down. I don't think it should be detonating at 20 PSI on 110 octane, so I think the stock injectors are kinda clogged or maybe the fuel pump is running out of voltage. I plan to remove the injectors and have them cleaned, and hotwire the pump. Hopefully that takes care of the detonation problem at 20 PSI and I can go knock out some 12's!
These cars rock!
