LS1 intake holding me back? I have a 2000 T/A M6 and those came with the ls1 intake rather than the ls6 intake. I keep reading posts with people who basicly have the same mods as me except they all have 20 or 30 more rwhp/tq than me.
Mods are:
"the bolt-ons", FLP long tubes, B1 cam with programing, and bone stock heads.
The car was dynoed with the cats on at 6200 rpms unfortunatly at 360rwhp/349tq. I read here most people are reving up to 6500 or even 6800 rpms.
What I'm asking is if taking it up to 6500 rpms and an ls6 intake with the off-road pipes on will squeeze out 20 rwhp.

Re: LS1 intake holding me back? I think your car will easily do 375rwhp/360rwtq with the LS6 intake and off-road pipes installed. I really think you have a little more in it than that.
I ran the B1 cam about 2 years ago and pulled 375/362 with Grots w/ off-road, all the bolt ons, and stock LS1 intake.

Re: LS1 intake holding me back? A few points...
Just because you rev to 6600 doesn't mean that your peak HP is made there. With a peak HP at 6200 you'd probably be shifting at 6600. So, you're fine there.
Dyno's can vary...ALOT! Dyno numbers from different dynos on different days should not be seriously compared. You may be just a different dyno away from a 20 HP gain.
The LS6 intake would probably be worth no more than 10 HP to you with those stock heads.
If those are FLP cats they aren't costing you more than 3-4 HP.
So, add it up. 3 here, 10 there, different dyno, a little tune tweaking, and you've got your 20-30 HP increase. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
