New best over the weekend.
I took it out to try the TH400 I just built and installed after 50 miles of driving in town. The track I went to is a 1/4 mile track but they were having issues with water seepage through the joints in the concrete in the traps the day before so they only let us run 1/8th. I only had time to make 4 passes, on the second pass I pulled the wheels a little & on the last pass got a best of 6.59 @ 105 with a 1.47 60' I figured it to be around 10.30ish in the 1/4. I didnt touch any suspension settings either, just 2 step & air pressure in the tires. I figured it did ok considering it had the 6 speed suspension tuneup in it.
On the downside I ran WAY out of injector and fuel pump (racetronix 255 & Siemens 57#ers) but never went lean because I anticipated it and tuned it fat for that reason. One of the benifits of logging fuel pressure I guess.
Anyway here's a vid of the wheelie pass, it also has a pic of the 6.59 slip that I scanned.

I'm now gonna shoot for a high 9 with a few more Pounds of boost, new fuel system, & 3.55 gears.

Nice runs looks like you should be getting your 9s for sure. I only hope I can pull off a 9.xx at some point in my car. But may have to go to a few outlaw tracks to do it.
No rollbar and not likely to get one. No rollcage for sure and no crap that NHRA wants for 9s.
I have other car that am going to use for track only car and even that one if it does 9s am going to slow it down!

Thanks, the 4.10's suck for the 1/4. I have the rev limiter set at 6500 and stayed in it on the 6.59 pass till the 1/4 traps and hit the limiter about 20' before the traps. I run a 275 60 15" drag raidial too, which is about a 28" tire, I could have bumped the limiter up a little and made it ok but its just not the right gear for a 3speed turbo car. Now I know why Lenny @ UCC (my converter builder) told me to change to a 3.55 gear before going to the track.
