Congrats on the GREAT build. Following your build and can't wait to see how she performs on the track either.

Thanks guys, I'll be going to the track this Friday. Racergirl might actually have to make some changes on the fast list for once...

Did you change out the driveshaft to a 1pc?

No I just bought the back half of a V8 driveshaft and put them together. I wanted one before but now I'm glad I didn't because a lot of people say it gives a all or nothing feel where the factory shaft with the rubber gives a much more smooth feeling. I know it would be better but I doubt I will be twisting driveshafts... I'm no Rick Hairsine.

Subscribed. Will catch up on this thread after I plow through speedster's build thread.

Well the day is finally here, track time! What's funny is I blew my old motor on Sept. 25th last year. Today is two days shy of being a year to the day. Hopefully I'll get to take it home in one piece this time. I'm a little worried about the transmission and if it can hold this much power at the track when I actually hook good. I'm going to take it easy the first pass or two and feel it out. I'll try to get a 2.0 60ft so I can see the improvement from last time out running the 12.1 times. Then if all feels ok I'll try to leave real hard and break some records...

Good luck, be nice to see you drop a full second first day back to the track

I'm expecting to see a 10.xx on your best pass of the night! Goodluck

Not sure if I missed it, but looks like you chose not to up the tb size, why?

Because I think smaller is better for a turbo car. More velocity. The turbos will make 18psi no matter what size the TB is, wastegates determine that. The LF3 twin turbo caddillac motor has a smaller TB than the LFX and makes 120 more hp. And I know a guy with 1000+ hp twin turbo v8 and he runs a stock unported TB.
