Hello all!

I'm new to this site and new to corvettes in general. I'm in the market to but either a ZR1 or Z06. I don' know enough about the cars to know the which platform to chose. I'm coming from the 03/04 cobras. I've had a stock eaton, whipple, single 78, and twin 67s cobras in the past. I want to get something a little more refined but still makes big power. I liked the torque of the Whipple car but heat soak makes the no fun really fast. With that being said i LOVE the look of the ZR1 but im sure they fight with heat soak issues similar to the 03/04 cobras. I also love the idea of a F1- series procharded LS7. With your guys knowledge can you please help steer me in the right direction? I want to be able to drive the car as i would a daily but that's not the plan. basically i want a 1000whp car that i can drive from Miami to Seattle with A/C and all the creature comforts without any problems. thanks for the help. please don't bash a me for being clueless cobra guy!

I have a naturally aspirated 630+ rear wheel Z06, and if I had your goals I would start with a ZR1. The ZR1 can make big power utilizing many stock engine parts. I must admit I have never owned a ZR1.

Former Mustang owner myself... owned many of them, including a modded '09 GT500. The ZR1 can suffer from heat-soak, but is a far-better engineered car from that perspective than the '03-'04 Cobra. There are coolers everywhere on the ZR1 in comparison.

Granted, once you really spin the blower to the power level you are looking for, you will have to do some cooling mods, like your would on your Cobra (better intercooler, heat exchanger, etc), but again... the car is designed better to begin with (not Ford bashing... its a much newer car, and was built to road race competitively, so it should be designed better).

Can a ZR1 make that on boost alone or will it need nitrous? I would prefer to make that power on boost and meth.



i get what you're saying. I am well aware that stuff will need upgraded i just don't want to deal with heat soak. Its stinks to a couple of lengths on a car on the 1st run, and then be even or get out ran on the next with heat soak. I'm not sure a ZR1 can even make 4 digit power without nitrous. I'd like to only use meth and pump/ethanol. Not a fan of nitrous.

You can easily make over 630 with boost only. From what I've seen posted I think around 800 is possible boost only with a modified stock blower and other mods.

For 1000whp, I would go with a forged LS7 or even a forged LS3 in a GS. If you’re not dead set on making 1000whp, I would go with the ZR1 and make 800-850, which is the sweet spot for these cars IMO.

Sounds like you don't want a cammed 427 600+ RWHP beast. A 800+ HP ZR-1 will run easy 9s with all the creature comforts. Sounds like you are not a NA guy. If money is not an issue. A C6 ZR1 is soo much everything for what you pay for a used minty one in 2018. Still very relevant for what it does even stock. You would be blown away driving one from what you are coming from.

C6 ZR1s are pretty damn good in stock form or somewhat modded with the factory SC during longer RR events without much fuss.

800 Would be fun but i also think i would get bored fast and want more. That's my fear. If i max out a ZR1 at 800 i think a Z06 is the better option for 1000+hp

I'm thinking the forged LS7 is the way to go. endless options. Why do you think 800 is the sweet spot?

yes i really want a boosted car. NA power would be fun but for me boost is where it's at. As stated above i fear i would max out a ZR1 and get bored. I wish there was someone local that had a ZR1 that would be willing to take me for a ride. I think that would help me decide what route to take.

thanks. Ill have to read and see what thats all about

ZF Six

The ZR1 is a much better platform. Easier to make big power, stronger trans, clutch, and rear end. You can make 1000hp on the stock motor, talk to Kong. There are several guys making 950+whp on the blower (heads, cam, ported blower, E85).

Unreal

Buy a prebuilt car, or start with a different platform.

It is very expensive to do a realistic 1000+ streetable car.

You can buy a complete one, basically get car for free for a fraction of what it would cost to build one.

I would not build a 1000+ corvette.

wanna_b_03

That's the plan. I want to buy an built F1-x/a LS7 or a modded ZR1. I like the ZR1 better but i think the Z06 is better for my intentions. Since i'm new to the Corvette thing i was hoping the guys on here could lead me in the right direction based on the info given.

have you sat in a c7 yet? the interior is more modern with better creature comforts. the c6 is 13 years old.

Unreal

I have a 1000+hp c6z. Probably the highest mileage of any at 1000+hp around. It isn't a realistic or good idea. Pick a different or better platform.

If you aren't mechanically inclined, and have a big yearly budget, forget it.

I had a KB 2.2 03 Cobra pushing 603whp and I had a 94 single turbo Supra pushing over 800 to the wheels. I have never been a Vette guy but I always respected the C6Z and knew I would own one which I do now. The ZR1 is nice and all but when you drive a LS7 and then jump into the ZR1, you will then have a better understanding why the Z06 is much more raw and engaging. To me, the ZR1 felt like a standard boosted LS3 Vette.

Patriot Six

800 is the sweet spot due to traction and the ability to maintain the car without significantly more expenses for cooling, drivetrain, etc.

I’ve got a forged LS7 at 837whp and I have no desire to increase the power.

Unreal

Patriot nailed it. 750-800 is the sweet spot.

As for zr1 vs z06, vs base vs grandsport, at 1000rwhp+ everything but the body/frame gets replaced. So it doesn't matter. Nothing will be stock, so no reason to pay extra for stuff that will just get replaced.

Sy1616

I had an 04 Saleen with supercharger, what a crappy car, fit and finish, feel, steering, etc. highly modded too and just crap. So prefer my 08 Z06 to it, night and day.

REDZED2

You really need to drive a Z06 and a ZR1. I have never read anyone who got bored in their ZR-1. Especially modded over 800+ hp. You would need 1200 hp in a stang to be as fast in a straight line. You should see how these cars can turn. That'll knock your socks off in a hurry. Wouldn't be looking in to a ZR1 for drag. Its much much more than that. Z06 forged 800-850 will be INSANE and a handful at that. You are at a level above the old cobra stangs that's soo unfathomable. You don't have any idea. It's much more than words can say. In a good way and every way.

I have not sat in one yet. the goal for this weekend is to test drive a C6Z and a C7Z. Im sure this will help me figure out which platform/ interior i will prefer.

I get that and thats basically what i plan for the normal power level. My ideal setup would make 800-850 on low boost but on kill would be 1000+. I have a good buddy with a C5Z with an f1x. He basically does the same. 800 for cruising and having fun but has 1000+ when racing.

i thought the weak link was the axles. For roll racing i didn't think any of the drive line components needed upgraded but the clutch.

I agree. i do need to drive both. i plan to drive a c6z and c7z this weekend. I cant find a ZR1 that someone/dealership would let me drive. I don't plan to drag race. Roll racing and cruising is what i enjoy.
