RE: New Edge Sixxer Question
But the rods and pistons are weaker than the 4.6. How come you can safely go to about 300ish rwhp on a V6 at around 11 psi of boost and that being considered the "safe" level, when you can go to about 400 rwhp on a 2v 4.6 and be in the considered "safe" level. Sure, there's some 3.8's that are well into the 400's, but those people are on borrowed time. I'm not saying the 3.8 is a weak motor. The block and crank are ****in' amazing. But those are useless if you snap or bend your rods or shoot a piston through your heads.
Not bashing the 3.8, just trying to set in some sort of reality to those of you who think the 3.8 is bulletproof to the 4.6.
Oh, and about the 3.8 taking to boost better than the 4.6, it's about the same. A boosted 3.8 at around 9 psi will bring it to about 250ish rwhp give or take. From 160 average rwhp stock, that's about 90 hp. A 4.6 2v will go from about 230 rwhp stock to about 340-350 rwhp on average with 9 psi. That's 120 rwhp gain. A lot can do with the tune, so let's just call it equal. But the 3.8 doesn't like boost more than the 4.6.

Like the qoute said "There is no replacement for displacement " but Im just saying 3.8 is hell of a block for the powr it can handle without being modified. Justin at VMP is runin TT on his 3.8 with stock internals. Car is runin 10s in a 1/4

I know Justin is running that power. But that's one person. Take 9 other people with the same stuff done to their cars and see those 9 have blown motors after a few 1/4 passes.
