Question...Modding the C6 for more HP?
Since just changing the intake on my C5 I went from 308rwhp stock to 336rwhp. That should be 362hp to 395hp at the crank. Now with the increased displacement, increased intake by 30%, increased compression and a bunch of other stuff seems there should be more under the table. Any thoughts?

as far as modding, it has a high comp ratio, so i guess there aren't goingto be too many supercharger/turbo cars without internal work. also i noticed the 200mph speedo

Re: Question...Modding the C6 for more HP? (number77)
the intake mod for C5 was the big bolt on winner but with the C6 saying 30% better than C5 looks like that won't do it any more? :confused:

Since GM was nice enough to increase the bore, helping to unshroud the valves, and providing a head design incorporating the best of the LS6 design, I am thinking there will be some nice camshaft designs coming....

Seeing that the LS2 looks pretty identical to the LS1 and the air box assembly in basically the same location as the C5, i see the current intake systems working on the C6... love to see the dyno results once the C6 comes out with a few bolt ons

Re: Question...Modding the C6 for more HP? (jimman)
Before you all go off into la la land dreaming of 50 HP in bolt-on mods consider the following LS2 tidbits that were presented in the Webcast:
- siamized cylinder bores (to be expected with larger bore)
- 40 percent more area with new 90 mm TB
- 30 percent reduction in induction system restriction
- 10 percent less exhaust system backpressure
- 90 percent torque bandwidth from 2500-5800
(I estimate 80 percent torque bandwidth from 1200-6500)
They've addressed the deficiencies in the LS1 inlet, and there is not going to be any low hanging fruit, so you may have to be satisfied with a measly 400 HP, but you can spend the money you save bypassing aftermarket bobbles taking you significant other on a nice weekend trip.

I see in the future:
No mods with good cost:gain ratios.
Mods that are advertised to have good cost:gain ratios, but actually do not.
A lot of lying by people who are trying to sell you something.

- Zaino: 15rwhp
- Aftermarket BSMs: 25 rwhp
- Exhaust plate: 10rwhp
There's 50 rwhp easy.
:lol:
J/K - I agree with everything above. I fear that an intake mod may not only gain you very little, but may hurt. My C5 had some marginal leanness when I changed the intake. Now with the increased compression etc. the C6 may be more sensitive to this condition.

Re: Question...Modding the C6 for more HP? (tbyrne)
I hope not. Us aftermarket guys need something to modify :) My plan was going to be induction and exhaust mods along with a Magnuson. After finding out what the compression will be that plan will change.
Mufflers and straight pipes, as always, for a different sound.
Stronger pistons for F/I
Lumpier cam -- the gain won't be as good, but it'll sure feel more powerful at idle. :lol:

Re: Question...Modding the C6 for more HP? (Scissors)
Cam + Long Tube Headers should get you to 450 hp (flywheel) without too much trouble.
I wonder how much can be gained from tuning with something like LS2 Edit on an otherwise stock car?
I wonder who will be first to dyno a bone stock '04 Z06 and a '05 LS2 on the same dyno the same day? Should give us a great baseline.

Re: Question...Modding the C6 for more HP? (Stunt)
Why I bet if you put on one of those throttle body bypass tube things on you can get 475HP easy!
Seriously, I think the comment about no low hanging fruit was right on.

Re: Question...Modding the C6 for more HP? (Timmy's C5)
If a stock bottom end LS1 will make ~500 fwhp with K&N/LS6 intake/heads/cam/long tube headers, then surely the LS2 will do at least that or better given the increased displacement and higher compression ratio with some long tube headers and a good tune.
I mean that's what I got and I'm making 418 rwhp or 492 fwhp (418/.85)
True there might not be any low hanging fruits, but that engine must be seriously underated from the factory if a LS1 can make 500 hp with a couple of bolt ons.

but seriously, w/ the increased displacement and compression ratio, and better flowing heads, I'll bet there's some nice potential in a cam swap and headers. :yesnod: :chevy

Re: Question...Modding the C6 for more HP? (need-for-speed)
It's looking like cam shaft will be the only viable HP mod. What's bothersome about that is now Bubba will get in there and upset the integity of the layout by pulling engine, always a scary thought with those left over parts. :)
