Re: J57ltr's 05' GTP, Injectors up, pulley down and some racing. Is it totalled?
So it's been a while and the car's been doing pretty good no real issues with it other than when I had the wreck it knocked the boot off of the passenger side CV and it is going to need to be replaced. The Drivers side front bearing has been singing since December. I never did replace the Radiator or condenser that were tacoed in the wreck since they have been working perfectly. I still have the new ones in the box in the garage.
Last Friday I got a call from my little brother who is going to school over at Hennessey Motorsports outside of Sealy TX. for tuning school and they were having a track day at their ¼ mile track. He was going to be working at the track as well and they were going to be trading out with other students to get the feel for how it works. He asked if I wanted to go and I said I would and he wanted me to bring my car to run it. Well I needed to do some things but nothing too significant so I decided to chance it. I tried to calculate how many gallons I would need to get there and back without carrying too much extra fuel, I settled on ¾ tank. Drove out there and used a little less than ¼ tank getting there (E85).
I met up with a friend that I had invited and we got through the gate and went to park while I went through tech. I removed my headlight as I have in the past and it was suggested to me to limit the amount travel on the front suspension and to get some spring blockers for the rear. Well I didn’t have time for that. Other suggestions were to remove air from the front tires down to 20 psi and raise the rear pressure to 40. Well I know from my days driving RWD cars that airing down steel belted radials is worthless as tits on a boar hog, but I figured I would give it a try. I had also switched to a 3.3” pulley

Realized that in the staging lanes I turned the car off and back on and forgot to turn the traction control back off, noticed on the second run it said traction control active. Doh!!

I noticed that I was running pretty rich in the low 10’s dipping into the 9’s. The engine was still pretty cool with me being in the 160 degree range and trans temp about 140. I also noticed that I was only getting about 10 psi where I was hitting 14+ on a 3.4 so I surmised that I was slipping. So I parked the car and went to get something to eat and watch some of the other guys race for a little bit and talk with my buddy, brother and his friends and look at my logs. So I was slipping the pulley and didn’t really have the timing I usually do only about 13-14 degrees where I am usually about 17-18 degrees. I had also asked Noah to check out my tire tracks as I launched. He stated that they looked like crescent moons and I knew the tires were cupping and weren’t really helping with the lower tire pressure so I decided to up the pressure back to normal on the front and put the 3.4 back on. Got to the line and launched at 2K as I had been doing. Laid into it a bit early and spun pretty good.

[email protected] try a little softer launch next time.
Went and sat and watched the races for a while contemplating my next move. Saw a nice Porsche running low 10’s all day long and a stripped Neon running mid 10’s. Watched an old about 85’ Chev full size crew cab dually complete with faded oxidized red paint. Looked straight off the farm. It was running mid-high 14’s and was a riot to watch. Saw a newer Ecoboost Ford truck that had an intake and FMIC click off 13.1’s they kicked some kid in a Dodge Cummings dually because he had oil and crap in the bed of his truck (Some people). Anyway I had decided to launch at 2400 where I had been last time I was at the track.

[email protected] car was cold again and made another pas a few minutes later but didn’t let it get all the way warmed up.

[email protected] starting to pick up a little.
A lot of the big guys were running and it was just too loud to hear what was going on with my car so I just sat out for a while. Then warmed up my car until I
was about 185 and went to the line.

Had a great time watched some cool cars and not so cool cars run hung out and talked with my buddy, my brother and some of his friends.
Things I learned or knew already. The car runs a hell of a lot better when it’s up to temp in the 190’s, airing down radials is a dumb idea and I need a smaller belt or larger tensioners for that 3.3” pulley.
