Well...

Some of you do not know...but I blew my engine in my 99 GT about a month ago. I just now tore down my factory engine. Piston #7 has a nice chunk missing out of it. About half the cylinders were full of coolant when I pulled the heads. I still haven't determined what caused the piston to burn. The burn is underneath the intake valve which is strange as well. I wasn't spraying at the time the engine popped and what few times I have sprayed I was only running a 100shot with 93 octane.

Any ideas?

I will be getting rid of some good parts soon...If you name it, I have probably got it.

Good PI heads, sensors, etc.

I wasn't spraying...but I was laying into the throttle.. There is no doubt about that.

Funny thing though...all the police cars hold up quite well with the SOHC 4.6

100 shot dry is pushing it, mine started to pop (detonate) at 75 shot dry, so i have a 50 shot right now untill my fuel rair adapter comes in.

how many times have you sprayed befor? and were you tuned? becuase the 4.6 should have lasted a long time if it was tuned good. the 4.6s are strong motors as long as they are tuned right.

People that are always saying that the 4.6 is weak is because their tune sucked. It's always in the tune.
