I ended up popping a head gasket at the track this summer. I had it turned up to about 20 PSI of boost and it was loving it...until "that run" LOL! I was using FelPro 1003 head gaskets and ARP bolts from when I originally built the motor and I knew there would be a limit. No major damage done, everything looked great on teardown with no signs of detonation pitting on the pistons. I had the heads machined to clean up the impression of the fire rings from the old head gaskets and re-assembled using MLS gaskets and head studs. I made the mistake of buying ARP's Teflon thread sealant for the head studs and darn near every single one of the 34 head studs leaked coolant when I fired the engine back up. I finally ended up pulling each head stud back out (one by one), cleaning the studs and the bolt holes and re-sealing everything using Permatex #2 instead. So far everything looks good, but I'm keeping an eye on it for a while to be sure no leaks (internal or external) recur.
I only got a few runs in at the track before I popped the head gasket, and only 2-3 runs on my "new" Mickey Thompson ET Drag slicks so I'm still dialing in the launch. 60' times have lots of room for improvement with my best being a 1.9 LOL. Best ET was a 7.77 at 93.8 MPH with a 2.000 60'. Best 60' and MPH were on the run where I popped my head gasket, racing an LS1 powered Camaro on a 100 shot of nitrous (I took him off the line and never looked back, even with blowing the head gasket, btw ) That run was a 7.9 at 94.5 MPH with a 1.9 60'. This is at my local 1/8 mile track that's only about 5 minutes from my house hahaha.
Hoping to get mid-low 7's next summer, but I'm pushing the limits of my current clutch too, so we'll see!

Handles boost great and I've been very happy with it so far. The self learning features are very nice and have helped me get things dialed in without needing a co-pilot constantly!
quadgoat wrote:That's why, once the map is dialed in, you are supposed to disable learning compensation under boost
You're also supposed to narrow the window of allowable compensation throughout the map once things are dialed in so that if something goes wonky you don't run the risk of throwing things way out of whack!

Do you have the self learning EFI? How do you like it. When I build a motor for mine, im trying to decided between self learning EFI or the LS engine management system.....or just an ls swap.
You still have the HSR or one of those carb looking TB?

Found out the poor little TC78 can't flow enough on the exhaust side for this new engine (no surprise there LOL!) She was pretty much out of breath at 4000 RPM. Put down 495 RWHP and 698 RWTQ. Peak torque hit at 3500 RPM. LOTS of fun on the street with that torque, but I've got to iron out a plan to shoehorn a bigger turbo in there so I can take full advantage of this new engine
