1000 HP 69 Camaro rear end help!

[out2kayak]

What are you going to use the car for? How are you going to make power? What sort of tires are you going to run?

I'm targeting 1000hp at the rear wheels. I'm running a Currie F9 IRS setup, with custom CVs from Driveshaft shop, Wavetrac, 35 spline, etc.

That said, I'm building power with turbo's, which is "gentler" on the drive train. I don't plan on dead hooking at high RPM, producing large amounts of driveline shock.

Besides, I expect the rear tires (345/30R20 Michelin) are going to spin if I hit it too hard in 1st, 2nd, or 3rd (and perhaps all the way into 6th).

The hardest part I've found is finding the transmission (without going to a Lenco) that will handle the torque. RPM Transmission helped me with a T56 Magnum and all the mods.

Have you thought about what ring and pinion your going to run? I'm using a 3:50:1 (pretty steep) and, without a dedicated track toy (i.e. I do plan on using it on the street), the options I found were limited.

Thoughts?

If your running 345 street tires a truetrac and 31 spline axles are all you will need, the tires will dictate EVERYTHING, and the additional 500hp you have will be good on the dyno.

What do you say would be the smallest tire I could run in the back? I planned on running 295/35/18 in the rear and 255/40/18 in the front. I didn't want to go too wide so I can drive around the street.

With 1000 hp with 295/35 18s you dont need to worry about rear end strenght at all. Tires will spin like an ice when hit the go pedal.

do you have a suggestions to what the biggest tire I could run comfortably on the street? I don't really want to run 335.

I don't mean to sound critical here, but you are not making sense to me. You keep talking about I don't want this or that because I want street manors. Why in the world are you then spending the money on 1000hp? That's a lot of dough to frame a dyno sheet. If you have 1000hp available, I would be listening to these guys and the recommendations they have provided to give you the best chance of using that power and not hurting yourself. Wide tires do not automatically mean BAD for the street. You need to choose all these components to compliment each other. I would put a 345 on that beast. You need all the bite you can get. If you don't want to do all these things my recommendation would be to back off on the power. Please don't take this the wrong way, but no one will be able to help you when your goals don't seem to agree with each other. JMO. Good Luck, sounds like you will have a wild ride!

Makes sense to me.

I disagree.......there are many many many cars in existance that hook EXTREMELY hard on this size tire (drag radial/slick) and will easily see 9 second passes in the 1/4. Even if your car does not come out of the hole at a clutch dumping or trans brake release of 6000rpm and you so choose to "walk it out" and lay into it.......your axle will still see EXTREME torque and the possibility of it twisting and or breaking is a strong reality.....I personally would like to know that at 140 mph+ that should I break an axle at the hands of 1000hp and a sticky tire that I will not go into a barrel roll. Lets also remember that this suggestion I make also eliminates all other known issues with semi-floater rears as well (piston knockback mainly). Hands down there are no down sides to a Full Floater (other than cost maybe...but in the scheme of things....) and if you are running 1000hp you would be running what I would consider a "marginal rear" at best with anything less that 35 spline axles with Full Floater hubs. Just my opinion and again hope this helps.

Sounds like a killer car but I though the same thing about street manners and 1000 hp.

This is SO F'N' true!!

I've always said that the "slo blow fuse" in my Nomad is the tires out back.... can't break parts when you can't hook it up for shizzlesticks!!!
