Who dyno's more the ATI, Greddy or Vortech?

Your question is too broad and depends on the set up of the kit, tuning, psi being run, etc. All these kits are completely capable of producing big numbers though and if tuned similarly will, I beleive, produce about the same or very similar power -- limited by stock internals of course.

Being that none of the systems have a stand alone engine management system letting them run in a true state of quality tune... rather then a half *** attempt that is just good enough to not instantly cause engine damage, its unfair to compare.

Wait until someone has their Greddy Twins tuned by a real system, not a E-Manage... and wait until someone has a Procharger or Vortech kit tuned by a real system, not a DFMU... then we are ready to compare the true potential of each system side by side.

If you wanted to compare out of the box results... well, i may not be the one to listen to because im not paying attention to every single dyno chart here... but it appears to be very inconsistant from car to car based on what I have looked at.

Out of the box, the superchargers are putting up higher peak numbers than the Greddy kit, mostly cause the lower boost setting for the Greddy kit. You also have to remember the differences in the power curves for an SC and turbo. Cause the turbo is at max boost at 3-4K, while the SC is at max boost only at redline, for the same amount of boost, there will be more area under the power curve of the turbo.

The Ultimate Racing and SSR TT kits are saying that they will produce around 400rwhp, which would put them the highest around. We really haven't seen a dyno from a stock Z adding the vortech, but the Gs are around 350rwhp. The ATIs are a bit more from the box, but it would be good to add some timing adjustment to them, which would probably put them around the vortech. Greddy has the lowest boost rating, which is why it is supposed to be around 334rwhp.

That is the info as I know it, correct me if I am incorrect in anything.

well, give me the three kits and $100, and I can make whichever one you want dyno the highest......it's all so easily manipulated that it renders lots of the results virtually useless

If any F/I car is detionating it is hurting it's self in horsepower. If you took some timing out of it, and cleared up the detonation it would infact PICK UP power. Detonation trys to force the piston the opposite direction it wants to go, thus lowers HP numbers. Free up the piston to do what it wants, and presto you have Free HP. If you drop timming, and you start loosing HP, you weren't really detonation in the first place. (there is more to that, then stated, but that is the nut shell version)

IMO from what i have seen on this board...... I think the ATI is putting the most power to the wheels.
