Sound like my junk, doesnt have enough power to break the tires in the burnout box. Leaving off the footbrake as hard as I can load it went a 1.78 60ft also Dont let it get away from you, its a wild ride going those 1.7s

Turn the power up. Turbo cars with no turbo make the suck At least mine does

Looks great man!

I'm getting ready to build a 92 coupe with a turbo LS1 for my local 275 drag radial class.

What does your fuel system consist of? What is your intercooler rated for hp wise? Class rules state I must run an air to air so i'm wanting one that will support 1200+ hp LOL.

Thanks for the info, unfortunately due to the class rules i'm limited to a A2A intercooler and can't run meth. This will be for an 1/8 mile racecar with very limited street time (might limp it to the Sonic some )

I was thinking about getting two 3 inch A2A cores and welding them together and fabbing up some tank ends. Seeing as you have a 4 inch thick intercooler now, do you think one that is 6 inches thick would fit?

Did you go back to stock gm exhaust gaskets? They seem to work the best.

They have worked the best on all of the turbo setups that I have been involved with as well.

they are rc 750cc. right now im working on getting a manuel boost controler so i can run 13lbs. but not sure how to hook it up.

also got a lpe 2 step at 3k it will only build 1/2 lb boost. how do you turbo guys get it up higher?

scratch the 26" tire idea, im sticking with 28s with 13lbs it will run out with the 26s

you and jesse are the only two.
3-4 lbs boost is fun with the 600s wonder how it will do with 13 lbs when the turbo starts becoming efficiant.

Put the 2-step higher. Should be able to build the boost up.

Not sure why your doing it in park/neutral, but trying bumping it 250rpm till it gets somewhere. In drive it should build boost easy with an auto.
