So today I ran a compression test on all cylinders and all fo that actually checked out. All were within 10psi of each other so I know the motor is fine. Now the blower is making wierd noises so I don't know whats going on there.
We have actually at this point determined that it is a fuel delivery issue. The loud pop I heard and why the motor has been running like crap 50% of the time is something in the fuel system just isn't keeping up when I rev the car. After I rev it hard the motor comes down and runs like ****. If you start it back up immediately and try to run it it just dies and won't stay running. BUT if I shut it down, then cycle the key on and off a few times (to let the fuel pump load and build pressure again) the car idles like a dream and runs fine as long as I don't rev it hard.
Results 31 to 40 of 40

What are you running for a fuel system? Which pump and injectors are you running?

Update. Knew this a couple days ago but it never dawned on me to post it. Broke part of the piston on driver side front off. Apparently it shot out the exhaust. I still have compression in that cylinder and the car runs fine. So I'm driving it until it finally pops completely.
I need a fuel system and may just leave the one I have in there until I too can find that extra cash to get the complete return fuel system w dual pumps.2012 Race Red GT w/ a 5 Liter and a 6 speed

Were you rnning the factory pump and 19# injectors? That's pretty scary.
If so then I can guarantee that's why your motor is done for.Dan

No I run 42lb injectors and a single Ford GT pump but that won't be good at that high of power. Probably gonna have to upgrade to 60lb injectors and dual pumps with a return style system.

Sweet. My goal from day one has been 500rwhp daily driven. I have a really safe tune in my car and she runs a bit on the fat side to be that safe. But now the next "step" up in power is gonna be an arse whoppin on my wallet for sure. S/B, trans, axles, clutch, intercooler....my wallet is screaming for mercy right now.
