What headgaskets are in it? Sounds like one might be partially blown.

Either that or the turbo's are hosed. Shane, have you heard of any failures with the ball bearing center cartigages?
We've done an exhaust test analysis of the coolant system, came up with nothing....I am going to pressurize the coolant stream tonight and re-do the test. I need to get to the bottom of this.

I would go with the headgasket/s as well. Considering the boost you are running combined with pump gas. You never really posted details about the rebuid unless I missed them. How did you break in the new motor? Or did you? Did you do any other work other than internals?

I haven't heard of any problems with dual ball bearing Garrett turbos, they are usually more reliable than the normal journal bearing turbos. There have been a lot of problems with the HP version of Cometic headgaskets though. They supposedly discontinued them and only sell the MLS one now.

Yeah, I am running the stocker MLS.
It could be a bad headgasket, but it isn't showing up in anything, I am doing another compression/leakdown test to check for it. God I do NOT want to pull the heads off.
Im going to do a comp test, break loose the studs, torque them to 100 and see if it fixes it.
If not, its time to tear shit down.

I put a MLS on my car last year and it popped immediately for no apparent reason. I put the HP on and that seems to be fine. Looks like I will use a mitsu metal in the future if this one goes.

Well got the nitrous figured out.

784.8AWHP, 660.1AWTQ 32psi +c-16 and 60 shot n20

1)My turbo's and intercoolers are pinned, only way to make more power is to add more nitrous, and I probably will.
2)I wanna go single next year, I am tired of the lag and heat, time to look at gt42's.
3)The car pulls 3061lbs of tractive effort in 3rd gear, that is nearly .8 g's of acceleration in 3rd gear!!

I am going to Rockfalls in a few hours, wish me luck.

Good luck. Go single and a nice huge intercooler.

I really doubt the turbo's are maxed, 392 whp for each 50 trim shouldn't be stressing it too much. The IC's though, I am sure they are totally maxed. Good luck at the track!
