I am set up to have the A&A Corvette supercharger installed on our 2002 Coupe. Stock hp is said to be 350 hp. After installation and tune, they said it should be approximately 525 rwhp. If this is true then our coupe should be faster than a stock 505 hp "at the crank" Z06.
Have others found this to be true?

There are other variables, but you're in the ballpark

A stock C6Z dyno around 435 at the wheels. You do the math.

500hp in a big cube NA motor will usually beat a smaller cube power adder car with the same power level. Torque curve will be steeper on the big cube motor.

However, it doesn't take much to move from 500hp to much more in the supercharger car.

You may make more peak power but the power curve and nice long tq curve of a NA 427 shifting @ 7 grand and making big power from idle up is hard to beat, not too mention the weight advantage. But as others said doesnt take much to go above 525.

A C6 Z06 weighs exactly the same as a stock C5Z so there is no weight advantage. The only advantage the C6Z has is powerband. A C5Z with a blower making 525 at the wheels makes 75 more hp at peak than a C6Z. It will be tough but I think the average stock motor, Blown C5Z would take down a C6Z.

He said coup, which is about 200lbs different than c6z, but I do believe a
C5Z with a blower and traction would have a better shot

And you have to add the weight of the supercharger and accessories.

Maybe one of these days, I will meet up with a 505 hp Z06 and we can see which one has the advantage. I was told that the coup has better aerodynamics than the Z06, so the top end speed should favor the coup. Off the line, maybe the Z06 would have the advantage. ???

One thought I had is that I hope that with the s/c and tune, that it will pass the tailpipe smog test here in Calif.
A&A has a "CARB" California Air Resource Board certification for all 50 states, but it still has to pass the tailpipe test.

Mine passed the sniffer test with ease. If you get it tuned right, you'll be fine

paint it black vette

hope you dont meet up with garyzo-6 or the land shark robz you'll probably come away a bit humbled

evo2ls1

Haha even with people with modded C6Z's do

mooney201

I am sure you are right... If it is not a stock Z06, my car would be in trouble.

I am just looking for about the same power as a new stock C6 Z06 has. If it is a little faster, then fine. I am happy with the coup styling.

realistically if your 02 coupe is mostly stock and is a 6 speed i would expect 490-500rwhp. so lets talk real here even if a 2002 coupe is 200lbs heavier than a c6zo6 but the zo6 dynos lets say 440rwhp the blown c5 still has 60rwhp. and what with the power curve? there is nothing like a centrifugal supercharger they are designed to make max hp and torque and max rpm meaning the higher you rev the harder it pulls. so in reality if you are a good driver you should be able to beat a bone stock z but i would just be happy rolling around with 500rwhp

What it really comes down to, is who can hook that power to the ground. You can have 1000 HP, but if you just spin the rear's - you lose.

I think the Z has a better chance to put it to the ground all things equal, I put my money on the Z no matter how many HP the coupe has.

EDIT - Special Ed for vettedave, things equal like suspension is stock, no slicks... if you still can't figure out what a level playing field is... wanna race?

Shirl

Interesting thread. I was actually wondering the same thing recently. Will you be taking it to the track? I'd be more concerned with good ET's and personal goals than what it's going to beat on the street. I'm sure it'll be faster than just about any street car that you run into. But the track tells the true story. Mooney, how much boost will you be running?

98vettedave

That's a ridiculous statement. I know a lot guy's with coups that would like to take your money!! If all things are basically equal (drivers,tires,gearing,ect,ect) then a large hp/tq advantage will most certainly produce the winner...Z's are great cars,but their not magical machines...except for Gary's Z that is.

Now why did you tell him that.

mooney201

They say it will be 9-10 psi. I don't want to run it at the drag strip it has a 6spd manual trans, but might run it at a road course. I have a low 10 second drag car. I just like the idea of having the power to stay with the new high performance late model cars.

kageryu311

Oh Noes! The C6 Z06 can never lose! If he lost its because the Z06 wasn't trying.

Lets be real here. More power plus similar weight and drag radials = C6 Z06 losing.
