And 8psi........LOL. Clearly someone down at Whipple screwed up. Ballpark boost numbers are easy. At 14.7psi (one additional atmosphere) you roughly double what a motor makes stock. That's assuming 100% efficency and no parasitic loss, which is impossible. So a 400rwhp Yote, which is pretty middle of the road with exhaust takes an additional .75 atmosphere to make 700rwhp. .75 atmosphere is 11.025psi. And remember, that's at 100% efficiency and no parasitic loss.

At 11psi a Yote with exhaust and headers will make 600-625rwhp. There is no way that it's doing it at 8psi. 11psi is also the octane limit of 93. So 700rwhp at 8psi on 93 octane is impossible on two different fronts.

-Most of the customer base is woefully technically unqualified to asses the performance of a supercharger they own. They have personal bias and the conscious or subconscious defense of a large purchase. And in most case they have only ever owned one supercharger which means they don't have anything to compare it to.

-And a few of the big names that have stellar reputations are tarted up junk. So you can't trust reputation.

I'm seriously curious where you think that people can get good, accurate, unbiased facts from? This is not me arguing. This is me genuinely curious about what you think. If there is a solution to the "problem" I'm all ears. Because I think it's a big problem (the lack of reliable buying information).

Additionally a lot of dyno operators are guilty of juke-ing the numbers higher through dyno parameter changes (keystrokes) because they know high numbers are what the customer wants to see.

I see more fantasy claims on the internet than realistic ones. 75% fantasy, 25% realistic.

With a smalller pulley, no cats, and with longtubes, running e85, I can see the set-up putting out closer to 650 rwhp.
But I wouldn't consider that a safe set-up.
Heck, I'm careful driving mine now, since I really can't afford to blow it up.

I plan on building my own engine soon, but I really want a GT500, and I'd love to build a monster 5.4 for it.

If you build your engine, what are looking to do?
I thought about the MMR 1000Kit. (forged bottom end kit and other stuff I would add on. I actually posted on it at the other Mustang forum. I added it up, it's HUGE money. lol Not including labor to do the MMR1000 and other mods install. That is why I am holding out at the moment. I have the funds, but I want to make sure I want to fully commit before the new GT500 is coming out as well as a couple other cars I am interested in.)
Good luck man! Keep us posted.

MMR, I would never buy anything from them, they have a terrible reputation.

I never knew that about MMR. I guess I need to some homework.
Who else would sell forged kits for the Coyotes Gabe? Good, quality stuff.
