tofski Member 30 Member For: 12y 8m 17d Posted 24/11/22 10:00 AM Share Posted 24/11/22 10:00 AM Not sure why that occurred, motor is running full copper 40thou head gasket with oringed block and head . Also 14mm head studs down to 150ftlb . Been fine after that run so see what happens. Link to comment Share on other sites More sharing options...

See how much timing is in it, if there's heaps more than 20 degrees it would answer at least part of that question. Was the block decked with 150lbft on the torque plate? Anyhow I'm sure you'll sort it out, you don't get a power figure like that from nowhere. Link to comment Share on other sites More sharing options...
tofski Member 30 Member For: 12y 8m 17d Posted 24/11/22 10:50 AM Share Posted 24/11/22 10:50 AM When that happened we pushed to see what the turbo would do and even after that no probs even with more pulls ,re the timing I'll have to ask the tuner , that said I won't be pushing the limits of the turbo all the time hard enough to hook up with 500kw on the street.

Seems reasonable enough. Haha keep it turned up man, just use the right foot to keep it hooked up 1 Link to comment Share on other sites More sharing options...
tofski Member 30 Member For: 12y 8m 17d Posted 24/11/22 11:08 AM Share Posted 24/11/22 11:08 AM Don't think it pushed past the gasket as it was doing 40psi same motor setup on c16 when it was the ETM f6 back in the day , I think the pwr expansion tank and cap are a bit dodgy , Gonna still push the limits 👍 2 Link to comment Share on other sites More sharing options...

Fox Body Barra New Member 5 Member For: 2y 11m 4d Posted 25/11/22 02:55 PM Share Posted 25/11/22 02:55 PM This is excellent. I'm trying to size a turbo for 1000whp that streetable as well. I was considering a g42 but maybe a g40 1050 is the way to go. On 25/11/2022 at 6:42 AM, tofski said: Not worried , done a co2 coolant test right after the run and come up negative .
