Rare ZO7

I havent been on the forum for some time, and am wondering if its been determined yet, that a LS7 ZO6 with CAI , Hdrs and Tune can put down about the same RWHP and RWT as a ZR1. Several articles I've read mentioned 505 at the wheels on the SC model. Then the only other major difference is tire and brake.

Comments??

No........ZR-1's are putting down 540whp........so a very strong bolt on Z would be close. A cammed Z should pull away.

I don't think a CAI , HDRS , and a tune are going to give you 133 HPs .
Mabe 40 hp at most .

lpe 660 package would be a close race

WeaponsGradeTorque

It's not close. Ask SABER. LPE 660 destroyed it. He's about 580 rwhp and 300 lbs lighter. Not even including the 373's...

Jasil

^^^^^^^^^^
Exactly..........LPE660 would destroy a ZR-1.

Man this age old argument again...

Look, IMHO it comes down to these two things:

1) You want to drive a stock car on the street
2) You want to tweak and jiggle things on your car for various uses

If you are (1), the ZR1 is the better car, period. It's just a better car. All around. Yes it's more expensive and whether or not that is justified is up to you and your pocket book.

If you are (2), there is no bad choice! I think it then comes down to (2.a) you care about bang/buck (2.b) you don't...

I think if (2.a) and you are dead set on a vette, the Z06 is the best platform for modification unless you are doing a ground up build and need/want that steel frame from the C6. If (2.b) then the world is your oyster, and I hate you, p.s., I am available for adoption.

Yep, we went from a dig, he pulled me by 1 car in 1st thru 2nd, I caught up in 3rd and we were side by side, as we went out to 185 I put a nasty pull on him" I said well I think I put like 4 cars on you " He said no more like 5... they have a better suspension for sure, more low end torque along with a better gear ratio in the tranny. Sweet car but I'm a NA guy all the way

You don't need 133hp extra to catch a ZR1. The heatsoak problem and the extra weight are the main contributing factors. Most of the car rags show only about a 2/10s in the quarter..and the gap doesn't grow much at higher speeds. I have all the MODs mentioned in the OP and I think I've more than made up that 2/10s.

Stop spreading the heat soak problem rumor. There isn't one. If 15+ more mph in the standing mile isn't a large gap than I don't know what is.

If anyone wanders to ls1tech.com in the videos section there is a nice link of a ZR-1 and it loses by 4-5 buslengths to a TT Gallardo.

^ agree, and also, I don't think the ZR1 is 300lb heavier, concidering they used even more carbon-fiber to counter weight the add of the supercharger and cooler...
You can mod the Z06 to catch and pass the ZR1...you can also mod the ZR1 to...well pass the modded Z06...I'm thinking a pulley swap and a tune might just do that...then again I know plenty of 1st gen camaro and chevelles that can run circle around both...the point? well, there's none...you can't beat what some thing "is". Even next to a 8 sec street car, the ZR1 will remain what it is, even if it is slower...

Jasil

Speaking of 8 second street cars Darin from Titan is selling his 8.38@182mph supra for 50K as we speak....A/C, stereo, cage, full interior.

Lawdogg

I heard directly from a forum member that tracked a ZR1 at Road America that there is a heat soak issue. It would be nothing short of amazing if there wasn't a heat soak issue.

Turbooo2u

Stuff it..I'll say whatever what I want..Talk to Carlos at Vette Air who has tested and written about the problem.

Turbooo2u

Not sure about bus lengths, maybe 2 or 3 football field lengths or so.

LFZ

all the car rags show the Z06 only 0.3seconds give or take behind the ZR1 in most aspects.

I have CAI, LT's O/R X-pipe, hi-flow cats and a cam. I'm putting down 545 RWHP and only 476 RWTQ on a conservative dyno. I don't think I'd pull away because the ZR1 develope over 500 RWTQ. But it'd be close...
