What am I doing wrong? I think my car should be quicker than it is with the modifications that have been done to it. I’d like advice from the Buick gurus.
Here’s the scenario. The car is an ’87 T-type with 129K miles on it. It was bone stock when I bought it almost a year ago. It's a light weight car. Solid roof, roll down windows, manual seats, etc. Here’s a write up from when I bought the car: http://www.turbobuick.com/forums/threads/my-turbo-regal-story-so-far.403508/page-2#post-3305097
It is essentially a bolt on car at this point. The motor, cam, heads are just like they left the factory 27 years ago other than stiffer valve springs that I added (not sure of the spring pressure, but they came from Kirban). I’m not sure what if anything has been done to the transmission, but the shifts are firm and quick. The trans is not an issue at this point. The rest of the mods are:
I've been drag racing for 20+ years, so I don't think the issue is me. Also, I weigh 150 pounds, so I'm not slowing the car down much. Today at a nearby track (Kinston Drag Strip in Kinston, NC) with a -200 density altitude, the car ran the following times. As you can likely tell, on the first pass, I got on the brake after the 1/8 mile since the track official told me they were not providing ¼ ET’s.
Why does this car not run quicker than it does? Please take a look at the Powerlogger file attached if you can. If not, a screen shot is below. Is the converter too loose for the stock motor? Is the motor too tired at this point? Am I expecting too much or am I missing something here?
Thanks in advance for the input.

- Precision 5931 turbo
- Alky Control Methanol injection
- Turbo Tweak Alcohol chip
- 60# Injectors
- CAS V4 stretch stock location intercooler
- Kenne Bell throttle body and plenum
- Pypes 2.5” exhaust (no catalytic converter)
- 3” down pipe from Kirban
- RJC racing boost controller
- RJC power plate
- K&N open filter (stock MAF)
- Walbro fuel pump
- PTC 2,800-3,000 stall converter (stalls closer to 4,000 at the track on the brake and a set of slicks)
- Powerlogger & ScanMaster
- 26” ET Drag Bias Ply Tires mounted on stock Turbo Regal turbine wheels (traction is not an issue)
