It wouldn't take many knock events to do damage at that boost/power level. The iat got to 60C at 40psi which is fine but got up to 91C at 45psi which is not fine. Ironically the water meth would have probably saved it. I stopped running it cos it was getting into the tps and making the car shut down. To be fair as well, it could have just been too much for that particular stock bore. I calculated 1350hp at the crank last time at 38psi, how much is it making at 45psi? 1500? At any rate there's lessons to be learned and I'm happy to do so. 1 Link to comment Share on other sites More sharing options...
xr6tForMe Donating Members 268 Member For: 11y 5m 5d Gender: Male Posted 01/11/24 12:21 AM Share Posted 01/11/24 12:21 AM Sounds almost fair that a block might not be happy at 45psi /1500HP? With broken stuff, I like to try to figure out the sequence of events. If you can figure out exactly what went wrong, you have a chance of knowing what to try to upgrade. in this case I think it would be interesting to know the bore thickness at different points and how the points that have split compare to the rest? If the bores are thinner at those points, you have a "dont use any blocks with bores that thin" reference point. Would also be interesting to try to figure out where the split started from and if partial grout filling might have helped? Sounds like "Operated outside of acceptable parameters" contributed too.. 1 Link to comment Share on other sites More sharing options...

I'll get a bore thickness tester when the time is right, that way I can check things for myself, rather than just sending a block and hoping it is good. Grout filling will help no doubt, I think I would prefer to sleeve the block and keep the extra cooling capacity for a street car that tows stuff. I know I'm gonna send it again so may as well give it a solid chance of holding together. Link to comment Share on other sites More sharing options...

Makes me feel better knowing how frustrating these turbo territory are to work on when I see what you have persisted threw with them. 1 Link to comment Share on other sites More sharing options...
