2.93 or 2.76 with 4lb lower on a ported eaton?

The difference is more torque, about the same hp and less efficiency. If you are going to the track, the torque will help your times. On the street, you will lose traction and heat soak quicker.

When you say " less efficiency" Do you mean because of heat soak or belt slip?

More heat is a by-product of spinning a supercharger past its optimal efficiency. This is why the blower will make more torque but the horsepower will not increase nearly as much if at all. Belt slip has nothing to do with it.

Yes 9.82....much lighter though

A 2.93 / 4# is pretty much the limit of the eaton in my experience. Once you go past that you for sure want some good cooling mods or for best results and ice box. At these rotor speeds the eaton is starting to just make more heat than power.

Cooling is the key!! :rockon: ... So far, I've had good luck with the 2.76" / 4# set-up

I do have an Ice box, Afco dual pass h/e, and a head cooling mod. Is that enough to keep the heaton some what cool? Maybe do a venom cooler by steig ..lol?

Forget the venom cooler and spend the money on a killer chiller

^ for a street car I agree on this

can you run the 2.93 and 4# lower on a stock eaton and not have any cooling issues? What kind of hp and torque could I expect. only other mods are slp cat back, K&N & 4:10 just bought the carand those mods were already done. Sorry if I jacked your thread.....

Yes. I wouldn't, but you CAN. If you know anything about these cars, then you know they hate heat. Don't even think about running two or more times in a row without a serious cool down in that case.

Thanks. So unported go with 2.93/4# What kind of boost and HP should I expect? Thanks again
