k, thanks... i'm new to the FI thing so not familiar with how much work is involved etc... will keep an eye on this thread

Seriously guys... i cant wait for you to develop something that will net me close to 350+ whp w/ a carb number and a worry free warranty :p

we can get close to 350whp without fi

I'm hoping for 400+ to the wheels with hfc's, exhaust, & supercharger kit.

Yes, that would be a good number. I wouldn't spend around $5K for anything less then a net of 80-100whp. When you think about it, that's $1K for every 20HP gained. :tup:

When will we get our day?

The VQ37VHR has been around as long as the LS3.

:supergay:

Any guesses out there as to when we will have a roots style supercharger? Or any good supercharger for that matter. I hate waiting...

I'm headed up to Stillen tomorrow morning. I'm going to ask how they are progressing with the S/C kit. I hope they come out with this kit soon. I'll put myself on the waiting list if they have one LOL!

Of course that small block has been around since the 50s sooo . . .

I don't think there is a single part that is interchangeable between the LS3 and the cast iron 4.3L OHV V8 that came out in '55, making 180 (gross) hp.

The Gen III Chevy V8 engines came out in 1997. The only thing that is the same between Gen I and Gen III engines is the bore spacing, which Chevy did only for historical reasons. The water jackets and head bolt spacing are different, so the heads are not interchangeable.

If you want to compare apples to apples, the Nissan VQ engines came out in 1994, making them 3 years older than the Chevy Gen III engines.


The most recent iteration, the Chevy LS3 came out in 2008, the same year as the VQ37 arrived.

Within 2 months of the Camaro being released by a bankrupt company that was obviously unstable for more than a year, the aftermarket swoons in with a kit that lays down 560 horespower to the wheels.

Where is the aftermarket support for the Z? It's technologically a superior sportscar that will have great sales worldwide. The Camaro on the other hand is a (low end) niche car that will only sell well in North America. You would think that aftermarket companies would be scrambling to get the VQ37 into top form. It's not like no one knew in 2007 when the VQ37 was announced that is would make its way to the Z car.

Some of us are here.. :p

LOL! The thing is that the LSx motor represent a huge achievement. One of the reasons people love them so much is for their versatility. The VQ37 is far superior technology-wise to the LS3, but the reason the aftermarket swarms to the LSx motors is because they're not only easier to make power on with virtually any mod, but they're extremely easy to tune. LSx motors are far less complex and are very easy to pull apart to work on. With the VQ37, tuners aren't even sure about how to tune the VVEL yet. LS motors finally get variable timing, but a simple VT lockout turns that off and you're back to the simplicity of the LSx. Also, remember that the LSx motors are single cam push rod motors, making cam changes a lot easier too.

I'm hoping Stillen's S/C is not a roots type blower, but rather a centri.

I vote for a "roots" type! More torque is more useful on the street. T

If its going to be a roots type blower, hopefully the rotors are Eaton's TVS design.
