Well I finally got to the track... Here is how it went..
Good.
Ran 11's
Drove there and home
No engine/drivetrain problems.
Bad
More on that later :D
First pass@20psi I blew an intercooler hose at the top of 2nd and ran 13.3@98mph.
Then I had several passes in the high 12's and low 13's with mph from 116-120. I ran 13.1@120mph on one of them :D
The track was not hooking up good. I was running 2.4 60 foots and had to get on and off the car all the way through 3rd gear. It was spinning the whole time in 1st and 2nd.
The track finally sprayed some VHT down and I made 2 more passes
Here is how they went
1st and 2nd gear at 14psi (Low boost on profec B)
3rd and 4th gear at 20psi (High boost)
60 ft 1.72
330 5.0
1/8 7.6
1/8 94mph
1000 9.9
1000 no mph
1/4 11.74
MPH 122
The car had no wheelspin problem on this one. I missed 3rd a little bit. Did not hit 5th but 3rd did not pop right in. I tapped the rev limiter right after i entered the traps
Then I tried a whole run at 20psi with the VHT
60ft 1.89
330 5.0
1/8 7.6
1/8 95mph
1000 9.8
1/4 11.67
1/4 123 mph
On this one I spun a bit at the top of 1st and had to let off. It pulled real good in 4th this time and hit the revlimiter before I entered the traps. Same deal with 3rd.
I am going Friday to the track again for a local monthly event. I am going to do a few things to get the numbers further down
I might bump up to 23-25psi (running 20 for these passes)
Bump revlimiter to 8200 and shiftlight to 7700 or higher (it is at 7100 right now)
I am going to hook up my tach for more consistent launches
Work on my 3rd gear shifting.
I "might" be able to get into the 10s. It is a bit tough with the head leaking like it is.
BTW the bad news is that I blew my hood off the car on one of the passes. I was working on a few things and dropped the hood and did not lock it right away like I always do. We have video of all the passes including this pass. It is funny to watch. The car still went 12.7@117 on that pass :D
The best thing of all is that the car drove there and drove home. Drove with coolant temps right at 185-195 the whole way there. Changed tires and gas (I have a system to remove the street gas out of the car so I don't mix it.) Ran my passes, changed the tires back, changed the gas back and drove home (40 miles there and 40 back). It is good to have the car still running..
Ohh yea I weighed the car also and with the addition of the
Heavier FE3
Heavier Turbo II trans, diff, and axles,
Full exhaust (just dp last time)
Full cage (HDHCDD Bar last time)
With all that and some stuff I pulled out I only gained about 40lb over the last time I weighed it. The car is at 2235 right now with gas and everything.

Also there was a Classic there with a GTi-R motor in it. He said his best pass is on street tires 13.5@115mph at 18psi. He said it is a modified T28 on there. I watched him run 13.8@111mph but he cracked his tranny case :( He said he is on the forum (Gtir Rookie i think)
Nice Classic though.. Too bad he cracked the case.
