if I were to get a LS2 C6 about how much RWHP would I gain with these mods (I just need an estimate... nothing fancy or mindraking)

1. full exhaust with LT's, X pipe and catback
2. 90/90 intake and TB
3. 125 wet shot with a clean dyno tune

not familiar with the engine so I don't know the gains from bolt on's [&:]

 

Lets see... LS2 puts out about 340rwhp+ full exhaust with LT's, X pipe and catback= 370rwhp+90/90 intake and TB=380rwhp+125 wet shot with a clean dyno tune..I would say you should end up with no less than 535rwhp. You will have a beast on your hands. I wouldn't race you thats for sure LOL

 

TB & 90/90 intakes 10RWHP numbers, is that mainly TB or is the 90/90 good for something on the LS2. I know it's good for something, but doesn't the stock intake efficient upto 500Hp(guesstimate) or so? I almost questioned your numbers there Mr. Rogers, but quickly realized I couldnt add this morning, lol. While we are at it...What will a full exhuast (LT, O/R X-pipe, B&B Bullets quad tip) system get my LS6??

 

Total rwhp would be around 450-550 on the spray, more accurately probably 500+-25.

 

Well the LS6 is better than the LS2 in my opinon. It also puts down more power to the rear wheels.(Mainly due to the C6s torque management) LTs, X-pipe and some B&B bullets will complement your aftermarket intake. You should expect around 380+ if you get another tune after you install the headers, X pipe and B&Bs. But you need to realize that your Z06 will be extremely loud with this combination! B&B bullets is pretty much like running straight pipes. They don't have mufflers, and then combine that with LTs and your begging for tickets. I also expect some drone from this setup as well. I hope you have an aftermarket sound system or your exhaust will be your radio.

My friend had LT's, no cats, and a Corsa and it was too damn loud on his GTO after his cam swap, before it was borderline, after the cam...obnoxious.

 

The 90/90 set up won't get you much unless you increase the CI or put on a set of aftermarket higher flowing heads.

 

At least on LS1's.....probably holds true for the LS2/6's as well. But alas, it is the best setup possible.

 

you would have enough power to do a burnout, we can all agree on that

 

Yea the LS6/LS2 intake is fine and not a restriction untill you start going to a bigger cam and/or heads.
