07-09 GT500 engine

[dutchrower16]

Thinking about picking up an 07-09 GT500, does anyone know what RWHP you can throw at it, safely? I have heard they are only good to 650ish to the wheels before the rods have issues. I plan on running full exhaust, upgrading the blower and running e85.

750ish

700-800. Keep the revs down and you can go higher, depending on your definition of "safe."

Just like they are saying keep the revs down and your fine. I just blew a hole in my block and I make 760.

I don't have one yet, I was thinking about it for me next car. Or a 03-04 cobra. I've had a ton of cars, just trying to figure out what I want next. I have always loved the way the GT500 looked. I like everything about the terminator, but the prices seem to be a bit high for a good one. And the SN95 was not my favorite body style. Plus I'm deployed to Afghanistan right now, so I'm just looking.

Honestly I was at 5800 rpms. Idk what happened a rod let go and made a window. I'm sure at some point I have shifted the car to high and caused my own problems. I'm sure anyone on the forum will tell you it's pretty expensive when you damage the block. I almost think it's better to pull the motor and put the good stuff in way before you have any problems.

I agree with above as long as you stay in the iron block years. The iron blocks hold more hp and wears longer.

I've always read that our motors don't like to be over-revved...is it safe to say we can run our cars to red line? Usually i run my car to the shift light but never over.
