If you pushed water, you lifted the head's.This is why you overheated on the way back. You will need to change out your head gasket's.No since on doing a compression check until you do that.
Yeah I have been down that road before, I have come to the conclusion that it is not a specific boost level, but a power level when it does it. 21 psi on the dyno, compared to 17 psi under heavy load on the track. I am going to o-ring this time.

New ride: 2005 YJ GTO A4. Stock as can be with a poop launch. 13.8 @100.9mph "Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, Totally worn out, and loudly proclaiming. . .'Wow! What a ride!'"
The whole suspension is Midwest chassis drag setup, 9", LCA's, PHB, DR Anti Roll, long torque arm etc. Afco coilovers in the front Afco shocks, stock springs in the rear. 3.00 gear 28" tires, crossing the traps around 6200. The most boost I have lecft at was 8 psi with the 1.33 60ft. This track probably could have held more, it will be something to play with.
thanks for the info, what was your trap @ 6200ish rpm? seems your rpm's are way up there for the mph?
driving on the street, what is the max boost you see, and when do you see it?
Chad

It has always been about the power level. I wonder if you can get a set of those gaskets or o-rings like they use in canada, I believe. A "pyramid " style head gasket or o-ring setup I think it is called? I had my old heads o-ringed and it helped out alot, but it eventually pushed water as well. How much timing are you at. It seems like 15-16deg. seemed to help out alot as well.
18 and over mine started to push water sooner.

155mph, I have a boost controller, I adjust the boost all the time, as little as 8 as much as 21, full boost by 4000 or so.

I am going to be looking into orings this week. 21-24* on E85 and it was perfect for a long time, until we ran in cooler air, and 17 psi.
It pushed before at 12* on 93 and 118 cocktail. It always seems to be right around the 1000 hp level on this setup with the L92's.

Damm Chris you got that bird flying !! congrats very impressive ! wish i was there to see it. You have came a long way you should be proud ! keep up the great work !!! SAM
Very nice man!! I have been following your build and you only keep impressing me.
have you thought about trying the L19 head studs? pricey but may be an option as well. I have a buddy with them and he is running patriot heads making 1000 to the ground with no head lifting. I'm pulling for you to figure out the head lifting problems since i am running the L92 heads as well
congrats again
