So I finally took my built motor to the track, and just one and only pass made I ran a 14.2@ 107mph. This was on about 17 PSI on my new turbo. My 60ft. was 2.4, and I did not launch hard out of the hole at all. This turbo is barely alive at 17PSI.

My MAFT is acting up all the time, and I have to get to the bottom of it soon as I still hit fuel cut around 18PSI...

I'm kinda dissapointed with the time I ran, but it's all about tuning and fuel cut. I was thinking about getting some 272 cams so I can use more turbo on the top end, but are cams really worth it? Regrinds that is.

My turbo goes full boost at 3.5K RPM. It's big.

I will look into slicks for use Tomorrow at the track...

If you end up doing cams I'd say do the valvetrain and possibly a port polish, that way ya squeeze every bit outta the head, eventually a FFIM if you don't have one yet. Slicks will help a lot and ya gotta get a good launch, no matter how much power ya got the driving makes or breaks it. Thats a good trap for such a high time, means ya got a lot of high end pull in it. Good luck, and have fun.

Thus the trap speed. With 107 you should be taunting the low 13's

ya, my friend with exhaust, filter, lex 550s spiking 14 lbs and dropping to 9lbs with no tuning ran a 13.8 @ 99. with street tires and a 2.01 60' and he still isnt that great at launching. you should be able to go much faster then that.

At 107 you should be in the upper 12's with a 1.8 sixty foot time. Tires and launch hard, run the dog shipe out of it.

That's actually when it starts to build boost. Full boost is near 4.5-5K.......
