I was with a friend of mine of the way to autozone in his KB GT500 when we had a highway run-in with a C6Z. First of all, his cobra is 647 RWHP but I'm not sure of the tq numbers. The car is insanly fast...probably the fastest street car I have ever been in. I was expecting us to walk pretty hard on the Vette.

We ran from a 45 MPH roll. The Cobra jumped out maybe 1/3 of a car length and held it until 100 MPH then the Vette just walked by us. I could not believe what I was seeing. We ran 2 more times with the same results. We followed the Vette to the gas station to talk to the owner a little bit. The carwas stock down to the air filter. I've ran a C6Z before in my car and it was pretty ugly. I knew they were fast cars but I didn't know they were THAT fast.

I'm seriously considering selling my car to pick up a used Z06 now. You don't really need to mod them at all.

LS7 > LS3????? Impossible.

Doesn't the Corvette weight like 900lbs less?

Something's fishy if he's putting 650 to the wheels. Most GT500s trap 113 to 115 stock with only about 425 to the wheels. Hard to believe another 225 WHP couldn't put him ahead of a bone stock Zo6. But anyway sounds like fun. You guys ever want to throw a neon in the mix give me a call.:D

I agree. A stock Z06 is on average 450 to the wheels. 200 more rwhp in the GT500 should be more than enough to take a stock Z06.

There you go. That Z06 had at least 50 rwhp more than a stock Z06 and the GT500 was making 640. Those races were neck and neck. Take 50 rwhp away from the Z and add 10 more to the GT500 and I see the GT500 walking away.

Are you in Tucson bro? I'll let you beat the crap out of my C6 if you want. ha ha

Ya, I thought it wasa bit strange too. I expected us to pull on him but we didn't. I have not seen the dyno sheet for the car but I don't know why he would lie about it.

Edit: How much would altitude come into play? It hurts FI cars more than NA cars doesnt it? We were damn near a mile high when we ran and he said he had his dyno tune when he was in CA at sea level.

Other way around, higher altitudes hurt NA cars more than FI.

well damn, there goes my theory. ha ha

Maybe he was on a different tune. I didn't ask after we raced. He was all butt hurt that he lost so I didnt want to put fuel on the fire. ha ha

The high-altitude performance of a turbocharged engine is significantly better. Because of the lower air pressure at high altitudes, the power loss of a naturally aspirated engine is considerable. In contrast, the performance of the turbine (Turbo) improves at altitude as a result of the greater pressure difference between the virtually constant pressure upstream of the turbine and the lower ambient pressure at outlet. The lower air density at the compressor inlet is largely equalized. Hence, the engine has barely any power loss.........Yes this is the second time this week I've used this and yes it is plagarized from a turbo sight.:D

well the aeroydinamics of the GT-500 are not the best, the faster it goes the greather the drag forces will be. In the other hand the vette is way more superior on aerodynamics and the drag forces will not slow it down as much as the GT-500.

My apologies, The GT500 was not on the 647 RWHP tune. I just got back from lunch with him. He said it was at around 540-560 RWHP at the time of the race. He only tuned it to 647hp for a weekend at the drag strip.

ok makes sense now, shoulda been a little better race.

What rear end gears does his car have? I was under the impression that the vettes were basically geared for all out speed...this would also play in the vettes favor for an interstate speed run...

Therear end ratiois 3.42. Transmission ratios for theC6 Z06 are listed below.


First gear:
2.66



Second gear:
1.78



Third gear:
1.30



Fourth gear:
1.00



Fifth gear:
0.74



Sixth gear:
0.50


Reverse:
2.90



Final drive ratio:
3.42

Hmmmm, still seems fishy. Dgussin, a guy on SVTperformance, has a tuned, pullied, intake and exhaust, with tires, and puts about 560 rwhp and about 550 rwtq, and ran an 11.4 @ 125. So, I still can't see the Z beating one, unless he was BS'ing about his mods. Either way, a KB GT500, easily traps 130+ in the 1/4, way more then enough for even a lightly modded Z.

I've heard that the GT500 needs the Intake/Tune and 3.73's to make it a drivers race with a C6Z. I believe with the evolution tune that would put the car right at that 550rwhp mark.

If it's not from a roll you'd need some LCAs and maybe UCA too since the wheel hop wouldbe insane in the gt500!

boy this is a familiar story....


guys I was there for the race I posted about... the Z06 is a beast of a car... the weight diff is huge!!! The Z is also geared for top end..... and forget the 1/4 times when roll racing. from a roll especially to triple digit speeds the Z06 is a KILLER!!!

How about this bargin turbo system for my Z? http://www.airpowersystems.com/corvette/tts07.htm

Can you believe that is considered "inexpensive"? :D

EDIT: not sure if it lists the price, but the kit is $11k plus shipping.

There's a tune that adds 100rwhp for the Shelby Gt?



Either way I think the GT500 needs more than a intake/tune and gears to match up with a properly driven Z.

Gears, intake and tune will give you the edge over a C6. You are still far away for Z06 territory. I've been down that road before and it wasn't pretty.

Mr. Rogers - intake, tune and pulley swap can be good for near 100 rwhp on the GT500

I'd say with a pulley, the GT500 will go up to about 560+ RWHP with a tune. I'll try to find this guys dyno sheet. Looking back, it seems he put down more like 570 rwhp and 560 rwtq. With just those mods.

I'm sure a tune, and pulley swap will get the job done, but that's not what was said...

A tune will probably add about 40 WHP if not more. Gotta love the 5.4 4V's. Ball park to say the least.

a k&n CAI has seen 40+ hp gains on the Gt500, so with a tune and gears im sure it could keep up with the c6z, but win no the races description should be ..............barn door vs needle point at high speeds

I hear what you guys are saying. My friends GT500 in a wicked fast car...I thought we were going to win too. I think he would win a 1/4 mile drag race but from a roll up to high speeds the Z just walked away.

He he pretty much murdered my C6 from a roll yesterday. It's a quick car.

Shocking. :eek:

With tune, CAI, pulley swap and idler pulley the GT500 motor can make 550 rwhp. Add Kook's long tubes, off road X-pipe, and a 75 shot and your in the 660 rwhp range.

Hey all, sorry I only get a chance to log on about 5 mins a day. I should have said a pulley swap too....the stage 2 is basically what I've heard is needed to hang with a C6Z ...plus gears. I'm going to go with the Evolution stage 2 eventually.

http://www.evoperform.com/shop/index.php?main_page=product_info&cPath=11_12&produ cts_id=4

I don't think I want to swap out the Eaton for a TVS, KB, or Whipple to try to keep it somewhat close to stock....so the stage 2 is the way to go for me. Oh yea, I should add LCAs again too...cause this thing hops around like a jackrabbit from a dig.

A little off topic, but I posted an offer on the Corvette Forum offering up a free flight lesson to anyone in my area that had a cammed Z06 and was willing to take me for a ride. I got a guy to respond (actually 2) who has an '08 with the cam package from the place I want to get mine from (http://www.thevettedoctors.com/). He's running a bigger cam then the one I was looking at , plus he has milled heads for 12:1 compression and upgraded rockers: 570 rwhp. He is coming by in two weeks. This way I can check out how it drives. He also had coilovers and a sway bar. I bet it is going to make me hate my car, but I have to see what it's like. I bet it is going to haul ass.

That GT500 should've taken that vette with that amount of horsepower, My car which has a kenne bell with a 15 pound pulley and making 552hp took on a stock z06 not too long ago and won. I have a vid on it I'll posted on youtube whenI go back home for the summer.

Ed,

I know it would be a hike for you. However if you ever want to see a lot of VetteRx cars, you have to come down to Captree State Park on a Sunday morning. There are tons of cars from that shop there. Most of the guys are freindly and if you were there with your Z06 I'm sure you could get a ride or two from some of them.

Dave

Thanks, Dave. I might do that one weekend. As for now, I'll take the ride in this dude's car. Another guy is going to swing by next week and actually let me drive his Katech car. That should be fun too.

Well, before I drop the coin, it will be nice to see what it feels/drives like. I have a feeling that the car is going to be severly traction limited. 570 rwhp is a car that light? I can only imagine.

Honestly, I think it is more of an ego thing. Does one really needs that much power, considering the weight of the car? I am interested in the sound though. I bet it sounds mean as hell.

ED, im suprised you asked the question "does anyone need that much power".....wow just wow you should know there is never enough power.

ED, im suprised you asked the question "does anyone need that much power".....wow just wow you should know there is never enough power.


Honestly, for a street car that doesn't have an all out drag suspension, there is a point where it just becomes "useless power". 570 - 600 rwhp may not sound like a ton to you guys, but consider the Z06 has IRS and weighs 3150 pounds or so. Gonna be hard to plant that.

I am not sure if you are serious or not, so I will answer it both was:

1. Joking - ha ha ha!

2. Serious - stated like someone that has never driven a C6 Z06 before. Stock horsepower more than overpowers the rear tires. I've busted them loose shifting into 3rd on the highway at 90 mph. Now add 150 hp or so. What do you think is going to happen? The Z is incredibly hard to launch. You can't slip the clutch without the risk of overheating the fluid and having the pedal stick to the floor. Dump and floor it and you got a ton of smoke and your ass end is going sideways. Even with DR's, you will overpower the tires with 570 rwhp. Getting it to run down the track as quick as possible will ALL be on the driver. You have to figure out how quickly to squeeze the pedal to the floor: slow enough to not spin and fast enough to make max acceleration. It's not easy.

can i try to figure it out with yuors?:D

Nice single post link there Bick. I remember that thread. The air attack LS7 has forged internals. I believe the air attack block also has sleeves too.

Which brings me back to my statement...

A stock LS7 is not reliable past 5-6psi. The block and crank can handle upwards of 900+ hp

So a company like Katech has to actually manufacturer the supercharger or turbo in order to know anything about it? Are ya kidding me?

Read the other post I linked. There is no weakness in the block. Do you need a built engine to run a lot of boost? Yes. Do you need a lot of boost? Nope. 4.9 psi psi and you are at 625 rwhp.

It's not the boost that kills the engine per se. It's the amount of power it makes with high boost.

Christ, I am not even going FI - why are we arguing?

All I'm saying is that if I wanted a F/I setup, Kateck is the last place I would go. If I wanted a nice heads and cam setup, Kateck is the first palce I would go. In stock form the LS7 is a F/I sensitive block. The engine is bored out. Why do you think they go with forged internals, sleeves and conservative tunes on LS7 setups?

I just had to ask Katech: Can you make 640 rwhp on the Z06 with all the bolt ons, heads and a cam. Their answer:

You're going to need boost or a lot more displacement. That would be like 720 at the crank (over 100hp/Liter).

EDIT: not sure if it lists the price, but the kit is $11k plus shipping.



meh.........don't go FI on the Z. Boost+LS7 = boom. not a good motor for that. n/a ftw.

The LS7 was meant to remain N/A. Cam and heads will have you safely 640rwhp...


I just had to ask Katech: Can you make 640 rwhp on the Z06 with all the bolt ons, heads and a cam. Their answer:

You're going to need boost or a lot more displacement. That would be like 720 at the crank (over 100hp/Liter).

Their answer - not mine.

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

Vette doctors >>>>> Kateck






You're joking, right? :D

Here is the rest of Katech's response.

640rwhp out of a NA 7.0L LS7 is laugh-able.

You're starting to sound like a fanboi!

EDIT: Also it a completely built enigine. See here: http://forums.corvetteforum.com/showthread.php?t=1474740&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
