Anyone planning on going to Pgh Raceway this Saturday?

[boostjunkie]

First, cool meeting you Welby. You have a really clean TType! Glad you had fun, that is what it is all about. Your reaction times got much better, was that because of my little tip? Get BF Goodrich Drag Radials.:biggrin:

Boostjunkie, is that you Shawn? Forgot to ask you at the track if you were boosjunkie.:redface:

86gngirl, are you boostjunkies sister? Didn't catch your name. Cool to see girls running 11.7's in GN's. :biggrin: My buddy running a TA said he thought it was 13.00 & faster needed a helmet also. But as soon as I got there I heard the anouncement for 13.99 & quicker needed a helmet. Luckily my neighbor hooked me up with a helmet just before I left. Wonder why they never said anything to me before?

First time ever got in 5 runs in one day! Bummer I could not fill up with Turbo Blue before racing. I pulled 4 lbs of boost out (back to stock length for wastegate arm) after the first run and still got some knock. Now for my question, did I do any damage to my car and how much? See info below:

Basically stock 'cept for Caspers Thumbwheel chip, adjustable wastegate arm, Walbro fuel pump, adj. fuel regulator set at 44 PSI, fresh air intake and catless exhaust. Runs were made with Caspers chip in 6 or 7 posiiton and adjustable wastegate set to stock length after 1st run (or 1/2 turn longer for the 5th run) running about 17 to 18 lbs. of boost.

1st run - 35 knock counts and I let up shortly after half track 14.124 @ 87 MPH & 60' of 2.39. Forgot to set things back to the 93 octane settings.:redface:

2nd run - 17 knock counts, kept in it the whole way, 12.874 @ 103.81 & 60' of 1.821. Back to 93 octane settings, never had knock with these settings before.

3rd run - got up to 20 knock counts & let up somewhere after half track, 13.002 @ 103.6 MPH & 60' of 1.903

4th run - same as 3rd run, 13.116 @ 103.29 & 60' of 1.971

5th run - Pulled out another 1/2 lb. boost but did not get knock readings since my laptop battery went dead. :frown: Never got 5 runs in before.... 12.700 @ 104 MPH & 60' of 1.793.

Was I crazy to keep trying? Since I drove it home with no problems I suspect any damage is minimal. This was the first time racing that I ever got knock. Kinda baffled me since I ran with 93 octane before with the same settings as I ran today. Don't flame me too bad if I was really stupid today, but I would appreciate some honest opinions.

My sister is Lisa with the GN she did run a 11.74 @ 118 mph, she was just real slow at the light with a 2.36 60FT She just needs a little work on the lights and she will go low 11s .with a little more boost and a good 60 its a 10.90 car all day long .

Your car does not look bad at all the way it sits. Was the air bag was in the coils in that pic? That may be why it sits a little higher in the back. Are your rear tires the same size as the front? My airbag makes my car sit higher in the back even with just a little bit of air.

BTW I love your wheels!

It never bothered me with the stock wheels, but I think because the tires are so short it really stands out now. They're only 25.5" tall. I originally wanted 275/50's, but they didn't have any. All they had were 295's and 265's. I didn't think the 295's would fit so I passed on them (although I now know they'd fit fine). The front's are 215/60's which are a little shorter at 25.2". Next time around I'm gonna get some that are a little taller to help fill out the wheelwells.
The airbag is on the car in that pic in the right rear, but it sat high in the back before I even put it in. This pic shows it pretty good, it looks like I have a lift kit on the back, or maxed out air shocks. I haven't been into that look since the early 90's . Thanks about the wheels, they're just 6" and 8" Centerline Telstars

I only had it to the track once this year. It went 11.36 @ 121 with poor traction. So it's running good. What is the other car your building? I also sent you a pm.

Hey John,
I'm building another GN. I dont want to take the first one far from stock, so this one will be the toy. Its still in the works cause we are trying to finish Toms Nova. So far that thing has been a money pit.

I do need a grill for an 86 if anyone can help me on any leads. I also need the dash and steering wheel. Donations are welcome!!:biggrin: Looking for reasonable price on those.
