As my sig states, I will be becoming a proud Corvette owner soon for the first time. I have some basic questions however. What are the average M6 LS2 and LS3 Corvettes making on the dyno? Not sure how extensively modded the car will be as I am keeping the TA. Wondering how much difference there is between the two power wise (to the tire). Need some help on what the difference are on the different packages (like Nav, HUD, memory, etc). Appreciate it everyone

 

C6 LS2 - TFS 225s/G6X3/ported FAST 102/LG Pros - 505-520rwhp
C6 LS3 - PRC L92s/G6X3/ported FAST 102/LG Pros - 510-520rwhp

C6 LS2 stock - 360-370rwhp
C6 LS3 stock - 380-390rwhp

 

360-370 is a little on the high side for an ls2, no?

 

I agree, more like 345-350rwhp for a manual LS2 I think (SAE corrected on a dynojet).

 

I agree, most "real world" m6 ls3's are 370ish stock......

 

I read in gmhtp had a black ls3 vette and the basline was 400rwhp stock dont know if anyone remembers the issue they did a head/cam

 

Still doesn't say much without knowing the type of dyno, type of correction, was there a spike in the graph, number of smoothing, etc.

 

ls2 are 345 to 350 rwhp and ls3 370 to 380 but both make around 460 to 500 ls2 and 460 to 520 on ls3 ( bolt on's )

 

Yeah ls2's are beasts with bolt-ons.......Set of heads does wonders....

 

Thanks for the responses everyone. Looks like I will be targeting an LS3. Can you guys tell me about the packages they come with? Car must have Nav and HUD. I noticed some have steering wheel controls...what do they do?

 

3LT is what you want. That has all the goodies. The Nav is not good, IMO. I have a pretty poor opinion of disc-based navigation.

 

 

Seems like all the used 08 or 09 C6's in my price range are automatic with the Nav/HUD. On the other hand, all the 6 speed cars are basic option (no Nav, HUD, etc). Been seeing these Cam/bolt on 08+ Corvettes on youtube making 475-500 rwhp. Thats awesome. Edit: Looking for black/black

The plan is to either pay for an 08+ in the mid thirties or put a significant down payment on a 06 or 07 C6Z. Having the coupe with no payment would be sweet, but the C6Z is my dream car.

 

Starting to think if I can just find blk/blk M6 with HUD even without the other stuff I may jump at it. Would I be better off just installing an aftermarket Nav?

 

I would go w/ a 08 C6 and i have seen them for $31,000 w/ 5.000 miles on them down here and w/ just headers,air intake,pully and a tune u will be right @ C6 Z06 HP.
