Hello, I am not really a newbie to my 240 (just to fourms), but this has got me in a bind. Bough the car and been working on swap since november 07 and finally got it running right and dynoed 8-9-08.... Being that I have never drove or been drove around in any rb or sr i need to know if every thing is cool or looks good. I will try to post a video i made of the build up and dyno run....and also a pdf file of the dyno....anyways my problem is my dyno graph doesnt really look likes everone elses, it looks just like a n/a motor, i know it doesnt have 500hp but it still seem like it should climb more once boosted. boost starts arround 3900-4000 and max arround 4500-4600 (wastegate fully open)

The turbo is a garrett t3/t04e 60 trim 63a/r. detachwerks 440s, my goal is 300whp (upgraded everything that should be needed to achieve that) the dyno is at 8psi at 227hp and 207tq, would 12 to 13 psi get me to 300hp or is the trim for that turbo not the best choice for my set up......lol thats my problem i think i have....thanks please help.-michael

What are we supposed to tell from the video other than that you have terrible taste in music?

You need to run more boost as that turbo is not efficient at such a low boost level.

lol...about the music i am just sick of hearing rap, nickelback and linkin park in videos.. and the video was mainly for a friend that lives accross country not for my question

but any ways, from reading about the turbo its 400hp compatible and 40psi compatible.......so by no means am i shooting for any of those numbers but is it going to take like 20psi to get 300 or i am in the right direction at arround 12 or 13psi? thanks for the fast responce

I'm starting at 16psi then working my way to 18 or 20psi on pump gas. The motor is a 8.5 c/r so don't be afraid to turn the boost up. My setup is a little different tho.
