Increasing temps.
I'm a little confused, if its jetted properly, why cant you just rip it for as long as you want....
Twister and I were talking about his turbo set up the other day, and he will hold it wide open all day long if he could....
The longer you hold it wide open the hotter the egts get....it just continues to build heat I guess. I talked to Jeff at Dakota Performance about this and he told me what I've already stated, the bore is so large that it just doesn't keep the piston cool.
Water temps don't rise, they stay about 125*, so I don't know what to tell ya.
I run 1/4 AV gas, and have went all the up to full AV to see if that makes a difference, but to be honest I didn't even see any cooler EGTs that people boast about when using AV.
I've jetted up from 450 mains, what Jeff recommended, to 470s, with external jets screws turned all the way out, and it really doesn't make much of a difference at all.
If I'm doing something wrong, or got my facts screwed up, please explain. This is what I got from Jeff and if anybody knows there stuff, it's him. Unless I misunderstood him, but I don't think so.
