And no, this is on the stock ECU with no reflash or tune. After i dyno the UR pulley im going to reflash and tune the same day. I have more mods than last time i got the reflash and i got 17whp from the last time. More mods so more corrections will be needed so im hoping for like 20WHP from that. We'll soon see...

Cams are bad to get... I also advise against them from personal experience. There's many problems that may come down the line from them... in some cases, detonation, drivetrain wear, valve and piston clearance issues, etc.
AH can still get other bolt on goodies, Transmission Cooler, Radiator, Oil Cooler, and UR accessory pulleys when they come out... Nitrous ;x

ANd to be honest i reallly see no point in going FI as so many people end up selling their cars about 2 months after they blew all that money. Some people maybe need more power but i am more than content with the power im making

Z1,
i think i remember reading in some other thread that you were working on some true long to headers for the vq, is that still going on or am i just making crap up?

[QUOTE=warmmilk]well if we couple the DE headers with some DE testpipes or HFC's, it should bolt right up, correct?[come on Z1 you know with the power the HR is putting down NA ppl are going to start jumping for it even more!!!/QUOTE]
long tube headers replace test pipes and cats. Sorry, I don't know if they bolt up to the HR or not. My understanding is they would not bolt up.
Far too premature to even consider at this point, and without having a car, it makes it even more difficult (we only have DEs here). Secondly, these are not going to be $500 headers, that much I know. Cost will be considerably more than even the Crawford ones are, due to material costs (321 stainless, real merge collectors) R&D (the prototype units are costing me quite a bit), and the normal costs of doing small production runs (should they be a success on my own car). In due time, we'll know the answers, but for the time being, we're working on a few other things first. Headers will be the last project we tackle this year

Not sure if anything has changed, but I believe the auto has a 3.2 final drive.
I wouldn't say 4.10s are perfect, but you will definitely have increased acceleration. A final drive/gears does not increase HP or torque, but allows you to apply more torque to the rear wheels so you get the sensation of more torque.
The downside is decreased mileage due to higher revs and a lower theoretical top speed. It seems that MPG doesn't suffer much and top speed shouldn't be an issue as you should still be able to hit 160mph.
For myself, I'd do 3.91 as it offers a nice balance. Either way, this should be the best bang for your buck out of all your mods. Man if we ever meet up, I hope it's soon because you're racking up way too many mods.

Never thought about it like that! Cool discovery.
