yeh its off their website. For the price they were asking for it though, i doubt they had all that many orders for the engine... I mean, I almost went for one at the price, but I later found other options. Look at the price of their non-sleeved longblock with the crank in there...

The gear ratios alone in the z06 (and viper) will leave you looking for 5th (in the 1/4 mile) while he is most likely only in 3rd. Also, unless they REALLY can't drive, their traps should be 125 or higher in the 1/4 mile and they will keep screaming all the way to top speed! lol
Believe what you want, im making just shy of 400whp on pump gas. If you noticed i did say the zo6 would start to pull after 90-95mph, basically right when he hit 3rd when we went from a ~35mph roll.. Im sure once we hit ~120 or so he'd start to pull hard, but up to 100 or so it's pretty much dead even. I've raced the new zo6 multiple times since my buddy has one, the viper only twice. I've raced my buddies dad''s ford GT and he would pull ~2 cars from ~35 - ~115, from a stop i'd take him but he didnt launch the car that well so a better driver could have done betetr im sure.. We didnt race the 1/4, but if we did it'd be close. my buddy is a good driver (zo6) and i'll usually jump on him about 2 cars off the line give or take a bit, and he's just playing catch up the whole time.
I've only takin my car to the track once, and it was horrible conditions. 95-100 degrees out (at fontana) and there was a ~40mph headwind with gusts in the ~60's.. So definately not ideal conditions, and i didnt drive perfect either, and i still pulled off a 12.2, so IMO with perfect condtions and perfect driving that could drop into the HIGH 11's for sure, which is what new zo6's run correct? I dunno why that's so hard to believe, but if you chose not to believe it, it doesnt matter to me, i know what i've done..

You want street driven reliability, daily driven, and 500hp out of 2.5 liters.

This is going to cost you, and cost you dearly I am afraid. If you step back and look at what you are asking, it certainly won't be "easy" or CHEAP to do by any means.

If you take the price of a brand new STi + the price of the modifications necessary to obtain these power levels safely, you might as well have bought the Dodge Viper that you are building a Subaru to beat.

Just my 2 cents.

Z06 is, what, $35k more than an STI (new for new)? I think you can make an STI quite a bit faster than a Z06 for less than $35k and be pretty safe.

AND you get two more doors.

Though the Z06 is pretty quick in the turns too.

New Z07/Blue Devil is going to be a supercharged 7.0L. To my knowledge, it is supposed to be around 600-700whp, and about 200lbs lighter than the current Z06. So it seems they are hitting the wall for displacement, but now getting into factory proviced forced induction [heaven help us when the tuners get a hold of one of those...].

I guess the plan is to release the new engine and then have the current Z06 become the new "base mode" [if you can call a 500hp car a base model...], and the new model becomes the faster vette for the next gen. Either way, I think a lot of people who just want a corvette as a midlife crisis are going to kill themselves with that much power as the base options.

Dont hold me to any of this, these are just the rumors from around the workplace [granted I do work at one of the GM R&D facilities].

latest info is that they're going to use the LS3 as the base of the SC'd engine for reliability purposes

Trap speed is what I am concerned with, not necessarily just the time they run.

400whp on an awd car that weighs almost what the Viper/ z06 do and doesn't have their power under the curve...something sounds off to me. Must have the magic beans? Oh well.

I didnt read everything so let me warn you if this is already been said.

If you do that set up think of it this way, at least you'll have a reliable 450-500whp that you wont have to worry about to much. Since you wont be pushing the components to the limit they will last longer.

More of a difference than that. STi is 30k new 04 33k for newer ones.

Viper is 72k
Zo6 is 70k

But u also have to pay luxury tax and gas guzzler tax and sales tax on these which get at about 80k but also Zo6 is hard to get at msrp most people pay almost 90k out the door 4 one.

i have been running that much power on the stock block for about 6,500 miles now. the car is not a daily driver, so they are all hard miles too.

when it breaks, i am going to just run another stock block with maybe forged pistons and tune it to 500 whp again... that is plenty of juice.

my best advise is get the right turbo for you and build around that....def. throw on the turbo kit first with the stock motor and run that until it fails and when your doing that same money on the side for the axis motor and you will have had some fun and probably in the long run save yourself some money

anyone can buy a vette (with the right kind of money of course), but theres far less 500whp DD sti going around.....wayyyy cooler

maybe, maybe not, at R&D facilities differences in opinion and unique perspectives are often encouraged. But it all depends on the CEO

Well, the CEO is about 500 miles from us. But all the high ups at my facility drive caddy's, and the high-high up has a C6 vette [company car] and a very nice GTO.

There are actually a lot of subarus in the lot, especially since it is western NY. They really dont like that since I have worked here, I have owned 3 subarus, and not a single GM. Everytime they tell me that I am not supporting the company, I have one response:

"Well I really only want two simple things. A car that is 300hp and that I can drive all year."

So far the best that anyone has come up with was the $80k caddy. Which isnt exactly in my price range. Besides that they pretty much start talking about the cobalt SS which makes me laugh. Then the saturn sky redline/pontiac solstice gxp's are brought up, which I do admit are nice cars, but cant use a RWD with any power in the NY winters.

So they keep badgering me, and walk away unsatisfied because they have no reason for me to buy a GM besides "buy American!!"
