Lol, yea . . . sorry for the typo . . . fixed! Thanks.

So? It got 0-60 a good bit quicker and only managed to drop a touch in the 1/4 and had a very weak trap-speed. No amount of "traction limitation" is going to account for this showing.

^^ Am i missing something here? Do you have the Stillen SC kit, and your saying you ran a faster 0-60 but slower 1/4 and trap? Weird... Can someone confirm this?

It trapped 113. I'm guessing that was in SoCal and in the summer. 113 is pretty good. Last summer with bolt-ons, but pre-supercharger, my highest trap was 104 mph. It's also 1/2 second quicker in the quarter mile than what all the car magazines were able to get.

The flip side though, is that in 2004 motortrend tested the z51 c6 corvette and it ran a 12.7 @ 112 with 400 engine hp. That's 115 hp less than what Stillen is claiming from their press car.

Exactly. The 'vette weighs about the same as a Z, and ran about the same time as the "supposed" 515bhp Z. That Z does NOT! make 515bhp unless the driveline is sucking up 150hp. Sorry. Not happening with those numbers unless they slammed the brakes on at the 1000' mark.

People are comparing results from different magazines. I've seen MT get a 4.6 on the 370Z vs. 4.9 from C&D vs. 5.1 from Edmunds & others. That's a 1/2 second swing on the exact same car. This is all before you account for different cars with different traction, etc. You just can't cross-compare like that with any reasonable accuracy.

Pretty sure the 4.6 was right :)

any stock Z on the street will be hard pressed to get the 4.6 thats claimed. More like 5. That 4.6 was on a well prepped track Im sure. Most cars have a hard time hitting the quoted mark.

I have no problems running 12.8009. with my 7 AT with bolt on's and its on the stock 19 inch street tires's

^ so we have NA Z's running within a tenth of the SC'd ones... Somethings off.... either the drivers in the SC'd Z are full of fail. Or we just do not have an accurate representation of a SC'd 370 1/4 mile.

Once I upgrade my CSC and clutch I will 1/4 mile mine and post the results

Since one of the strengths to the Stillen kit is the room for upgrading by being able to make more boost than the initial kit setup and therefore power with the Vortech unit, how much more power could it efficiently make?

The V3 stillen spec'd is rated for max of 22 psi. Not sure what that equates too

Oh wow, so it is safe to say it can probably push enough power to run into the danger zone on a stock VQ37 then. Thanks Lateral!

Probably enough to push two pistons out the hood, 2 out the side of the engine housing, and two through the oil pan. :D
