A lot of people run 150 shots. But there are also a lot of people running boost on the motor no problem. A friend near me is pushing 650hp on stock internals except valve springs, pushrods. He only needed those mods because of the cam.

Now is that safe....... That is to be seen. But there are a ton of guys pushing over 500hp no problems.

 

5.7 gto here in kc
put down over 700 to the rear tire on 11 psi.

stock block.

 

An LS1/LS6 can handle 8 pounds comfortably. It would dyno between 540-580 rwhp on an LS6 with a 3.5" Kenne Bell Twinscrew set up. That would amount to approx. 635-680hp. THAT is with the supercharger only, no bolt ons of any sort. So yeah, it takes plenty of boost. You don't need much anyway with a 5.7 liter engine.

 

The LS7 loves a nice lumpy cam.

 

Any ls motor loves a nice cam.

 

lol Exactly. That's like saying a car likes gasoline.

 

Wasn't talking about the whole lineup. Was just saying the LS7 would be better suited for a cam then boost.

 

there was a c6 z06 on a 100-150 shot trapping 135mph at the track about a year ago when i went...

 

And what information do you have to back that claim?

 

The two local LS7's that blew up with vortech kits. Static compression ratio is too high on the LS7 for boost. N20 or a nice lumpy cam is the best way to go.

 

I would never put a Vortech kit on an LSX block anyway.

 

ummm they get sick from 0-190ish. that car is just fast.

...in what?

 

Probably his C6. Then again, I dunno.

 

I saw a c6 z06 race a 400whp evo on the highway. lets just say the evo looked as if his car stalled. I'm trading in the balt for a new zr1. hehe

 

CR is high, long stroke, etc. etc. etc. When you build a large displacement motor specifically to make big power numbers n/a like gm did with the ls7, it takes away alot of the positive characteristics for forced induction. The ls7 is not a good candidate for forced induction and when you are talkin about a 15k motor, you better have lots of cash to **** away if you try it.

 

the z06 is the best car for the money. I love the sound of those things. Every new model the vettes increase the hp dramatically. By the year 2015, they will have 850hp stock and still get 28mpg on the highway.

 

H/C C6

 

ahhh i see. i hadn't seen ur updated sig and i though you still just had like...the camaro. i was like uhhhh what now?!

 

Higher "CR" yeilds better hp per pound of boost. yes you might have to run c16+ but your statement is not true. The only reason people lower "CR" is to make it more fuel freindly and are cheap ass and dont want to use race fuel.

Lower CR higher boost = Higher CR lower boost.

I think the zo6 takes very well to boost.

 

Ill come down next summer with some of my buds with cobalts, mustangs, and skittles, NJ isnt too far away.

later

 

My sig changes on a weekly basis

 

...With all this talk about 'no boost'... I take it nobody has ever heard of Lingenfelter? ... or the SC and Twin Turbo kits they produce for the Corvette...?

 

somewhat true. with all things being equal yes, but running as aggressive of a tune as you can run with low cr, high boost on a high cr low boost application is gonna make for a quick boom. That ls7 you linked to...is running 9.5:1. Here's one of the main reasons why-

with low cr and the potential for high boost, you can make great power on the street extremely safely on pump gas all day long, then if u want to, go get some race gas, tune for it and make significantly more power. With a high compression ratio your tunes have to be very VERY conservative on pump gas, and ur boost very low. a powerful f/i ls7 with the stock longblock is not going to be a street friendly car at all. there are MANY reasons the ls7 is not a good candidate for forced induction, those are just major examples of why, but i will site more if you'd like, it really is pretty interesting.

 

They build up the engine when they use twin turbo's

 

do you have any idea how far from stock an ls7 is once it comes out of linginfelter? I'll give you a hint... its farther off than this car

dont get me wrong guys, the ls7 is bad ass as hell, but it is not a good base for forced induction at all.
