My car lacks performance in a big way. I just is plain slow. best e.t. 13.9@101.2 with a 2.4 60' with race gas and 20psi and 43lbs Line off. It spools slow, everything about it is slow.
Here is what has been done so far:
87 GN:
Spring cleaning
TA-49 adjustable actuator
009s
Adjustable FPR (Fuel pressure rises with boost correctly)
Hotwired 340 pump
Turbo Tweak 93
Reds 93
Transmission with re staled D5 (2800 rpm)
Valve springs and seals (Kirbans)
Timing chain
Water pump
Various gaskets on motor
Coil pack, wires, plugs (GM,MSD, Stock AC Delco)
HR motor and tranny mounts
Volt booster (Reds)
Kirbans 3" DP
Hooker Cat back
Homemade cutout by me (which turned out badass by the way)
Fixed exhaust leaks
Checked waste gate puck for sealing OK Definite ring on puck and housing
Waste gate solenoid (checked lines and y are all ok and routed correctly)
S-10 wheel cylinders
shoes and drums
Vaccum brake conversion
SSBC calipers and slotted rotors
Fiberglass front bumper with aluminum mounts
This car should be a rocket, it just feels sluggish. It won't build boost from a stop, and doesn't start to build boost until its halfway through first gear. Since I did the valve springs I'm getting knock all over the place with either chip ad recommended boost and FP settings for each chip.
Please help me. I'm new to Turbo Buicks and I'm fortunate to have some friends who are experts. I am so frustrated, disappointed, and baffled. I read on this board everyday and talk to very knowledgeable people often. I would just like to see some other Ideas, you know the more heads the better. I hope I gave enough info. I will try to fill in any blanks I may have left.
Thanks and sorry for the book
