Well see how things go.. 650whp will tend to heat up a lot of shiet real quick.
I bet there will be some sort of aftermarket meth injection kits to help cool things down.
Talking about heatsoak, my 09 RT Charger with a Magnacharger at 6 psi also got hot pretty quick. I didn't like that at all. It took the consistency and through it out the window. Anything from 12.1 to 12.9 depending on how many times in a row I ran it.
