LS6 Manifold question.
Please check out my sig. I am looking for advice/opinions. I'm looking to upgrade my performance at this time. It was suggested to me that I purchase and install an LS6 manifold and that would give me an increase in performance. I am thinking maybe +7rwhp and +5 rwtq increase. I can do my own install so it wouldn't be that hard. But I wonder if those are the numbers I should expect. Any experience with this? :confused:

It depends on how much power you're looking for. I've seen 8-15 on a stock LS1 and 15-25 on a car with headers and all. Like I said, it depends on what you're looking for. I have a GP for 410.95 shipped with coolant pipes and plugs if you're interested.
Thank you-

I have a 99 FRC and the second mod I did on the car was an LS6 intake (the car came with a vortex rammer and coupler). The first mod I made was a Z06 Ti cat-back. I felt a very slight bit of difference after this mod. If I were thinking of doing this mod now, I would wait for the LSX manifold, especially because you have the ported throttle body.

The pre-01 LS1 manifold only shows losses at the 400 fwhp mark. This is when it becomes like a bottle neck & might possibly hinder performance ( In your case I would suggest the same since you have already upgraded your exhaust & some parts of your intake ). Average gains are 7-10 rwhp & tq. ( On bone staock engines modded are higher- Not bad for around $ 400 ). The LSX intake looks good due to the larger TB size but it has yet to be released & the price is about $ 300 more for the 78 mm model ( so it will only give you benefits if you go to a larger TB BBK 80 mm for example ) The larger one is more expensive still .So it depends on you really will you be one of the first test drivers of this new intake ( another reason for possibly choosing the same is the laughing gas since it has integrated NOS ports ) & like i mentioned your goals. Will you put your vette on the "squeeze" & are you ready to fork he extra dough. Personally i went for the LS6 stock intake.

Re: LS6 Manifold question. (V8_Club)
This was the last mod I did a couple of months ago. I already had the 80mm BBK TB, MAF & K&Ns, etc. There was a definate SOTP increase at midrange & above. I feel any SOTP mod is worth it. You will need to Edit. :smash:

Re: LS6 Manifold question. (skidmarc)
After all my intake mods, AutoTap indicated fuel trims at +20%. So be sure to AutoTap (or some other program) & see where you stand. Even before the manifold change I was at +15%. :yesnod:

Re: LS6 Manifold question. (newberd)
I did mine in conjunction with an LS1 Edit session so it was hard to tell if it was manifold only but there was a definite increase.
