I have 4:10's and run a 315 drag radial, and a STS kit. Its only on 5psi for now, but I will be putting 6.0 heads, and a meth kit and will be uping the boost and to 10 or 12psi and it should be making 500hp or more. My question is will the Ls7 clutch hold up for my car's setup?

 

I would say not.

 

i would say yes, because LS7's make 500hp stock, and there are ppl spraying 100+ shots and the clutch is holding up just fine.

 

I have the ls7 and it holds like a mo!

It was designed to handle a minimum of 500hp! There are no issues with this clutch like the other aftermarket horror stories that you read about here.

Buy an LS7 clutch and never look back!

im wondering the same...when my SPEC goes will a LS& hold my hp and tq??? i like to read more opinions

 

I'd suggest Centerforce DFX or Spec 3+


-Will

 

With the combination you're talking about, it's more like 500+ rwhp. If you intend to launch the car at all, the LS7 will not hold up.

 

I have heard alot of bad things about the spec 3, what would be a good clutch to go with?

 

My car was putting down over 600 RWHP on spray and my LS7 clutch held

 

yes alot of bad things about the spec "3" not the 3+ total difference. I have the 3 and hate it. the ls7 will work great for your application.

 

if youve got the cash ive heard nothing but good things about textralia clutches

 

what does your car weigh?

 

I know many stock c6z06 guys who fight them prety hard. They have a tendency to glaze. If you are gonn abe at high boost...and hopefully more than 500 hp with what you stated...I would go aftermarket

 

Not sure, but should be close to stock. I have not done anything to make it any different.

 

What would be a good aftermarket clutch for this set up?

 

The LS7 may hold in your car it may not. I have one and I love it but I only have 360 at the tire. There have been some guys with stock Z06's that have had issues with the clutch holding under hard launches. You may want to look at a Tex or a twin disk. I haven't heard of any twin failing to hold power unless it was just a rediculous amount. I am not a fan of Spec clutches but there are guys that swear by them my opinion is they suck and so does thier customer service. Tex seems to be the best as far as customer service and the clutch holding up. There are several good twins out. Shop around for what is in your budget and then ask around for opinions on those clutches. Just my .02.

 

A Spec 3+ will hold if you can drive it properly, meaning VERY little slip from the stops. LS7's can do it too but does not like higher rpm launches or agian excessive slipping. A Tex oz700 should do you very will and run like a champ.

 

Spec 3+ is a full face clutch, it should fare better than a Spec 3 which is a puck design. I'm not sure on the Tex... but the full face clutches should be more friendly on the street.

 

you got some extra weight will all the turbo stuff so... if its +3600lbs ish i would not go with a LS7 the vettes can run that with big power bc they have a light as*car not a pig like camaros and firebirds. i had a spec 3+ in my camaro and it worked flawless for me.
