It's called the Rx 750 package. 640rwhp N/A. 7.0L

Vette doctors >>>>> Kateck

 

You're joking, right?

Here is the rest of Katech's response.

You're starting to sound like a fanboi!

EDIT: Also it a completely built enigine. See here: http://forums.corvetteforum.com/show...740&page=2

 

No seriously Vette doctors > Katech

Once again you have ran to Corvette forums trying to defuse my claim.

That was a 640rwhp 7.0L N/A LS7...was it not?[&:]

Not laugh-able at all...

Your Katech expert said that more displacement or F/I was needed...which obviously is not the case.

There was also another Vette doctors kit making 620hp - the beefed up internals.

 

I don't run anywhere. I visit that forum all the time. Katech claims it was bs and I believe them. They are Katech, for Christ's sake. Also, you said heads/cams will safely net 640 rwhp - no mention of a ton of internal work like that (assuming do dyno manipulation). That is a false statement. You say what needed to be done to achieve those mythical numbers.

I'm done. There is no winning with you. Heads/cams and you got 640 rwhp. I give up.

 

The main point of this is that 5-6psi is the limit for a safe stock LS7 F/I setup. You said that Katech dispelled the myth by putting high boost on a fully built LS7. If it truly were a myth, katech would not need a special block for their F/I setup.


"Nope. 4.9 psi psi and you are at 625 rwhp. "

There are a few guys running 6psi and netting 560-580hp. How did someone get 625hp out of 4.9psi?[&:]

 

HP is HP. You can only run so much power without getting into forging the engine, be it N/A or otherwise. Agreed?

The LS7 can makes a lot of power with less boost. I agree with the max 6 psi because 6 psi on the LS7 put it in the danger zone for power on stock internals. You will be over 600 rwhp at that point, which is pushing it for the stock pistons.

But the fact remains is that you can boost an LS7 motor and you don't need a lot of it to reach the power level where the stock internals become in danger. Forge the engine and you can push over 800 rwhp with a boosted set up.

If it is even possible to make N/A 640+ rwhp in a street driven LS7, you are going to need a built engine too. See my point? It the HP level.

Now can you stop getting sh!tty with me - saying I am running to the Corvette Forums? I go there all the time and Jason from Katech is a cool guy. I am a big C6.R racing fan, so Katech carries some weight with me (and most in the Corvette community).

 

alright.. you girls go argue about this in PM or something
