BER talks about the ported LS3 not the ls6 making numbers like the Fast.

I'd go for a FAST. We have nearly the same identical combo. Mine at the time dynoed through a Kooks Catted Y-pipe, which I believed robbed me of 3-4 HP. Now I have off road X and duals dumped. The FAST #s to #s right now is 15 RWHP above your current number. You could definitely see the 20 RWHP you're looking for with a FAST and ORX. I know it's not apples to apples with different dynos and other weather and tuning variables.

There is a link in my sig to my dyno thread.

TPIS tested a 90mm LS6 against a FAST on a large cube motor and made within 4-5 HP and equal TQ. If BER can find gains porting the runners then it may be equal in performance.

I thought the ls6 was good for around 450rwh until it becomes restrictive?

As a newbie to this LS stuff, I have to ask. How in the hell can they justify $800 or so dollars for a hunk of plastic and not even include the throttle body??

The volume argument can't be made as the LS engines are the hottest engine going right now. So there are plenty of them out there.

I can go to Jegs site and buy a tunnel ram manifold with 2 Holley carbs, fuel line, linkage and gaskets for a SBC for $950.

my tuner informed me their markup is ******* insane. i got raped on my 102 im sorry to admit. nice part though.

Yea, anyone with common sense knows that $1,000+ for a molded piece of plastic is insane, even with the r&d involved, which I assume wasn't too extensive.

What do I know though, I'm no expert.

First of all it's doubtful you can find a ported fast 90/ p&p 90 tb for anywhere under $1000...

Second of all every single dyno test I have seen with a fast Intake swap (90, 92, 102) has always picked up low teens hp in the higher rpm range and only picked up under 10 ft-lbs...and all that comes at a price because the fast almost always raises the power band as well as low end torque sometimes to a tune of 10+ tq under 4000rpm....

All that being said I wouldn't waste my time with a fast intake other than a mamofied 78mm unless you have the cubic inches to deem it necessary...just my .02

Not sure what dynos you are seeing I have never seen that. The 102 will own any FAST period because of runner design. They accept 90 or 92 TBs so there is no need to buy a 90 manifold

The 102 will own the 90?? Please post a link to the proof.

I have a busted lower end on my 90 and to be honest, I haven't seen good data reported on the 102. I've got to buy something, but not sure about the 102 yet.

I myself want to add a fast 90 or 92 if i could find one. Guys have dipped into 10's easily with an LS6. So its kinda tempting to just keep it.

Tony himself has came on here and said the 102 is better than even the 92. I don't need a dyno sheet, I trust the man's word.

However...

Insanely expensive. Wish I could afford it. When I finally do pony up and get one, the hoods getting replaced and the cowl is getting cut. If I'm going to run one, I'm going all out and running the LSXRT truck version.

Hit up sweets10v8 he should have a chart. But on your setup that 90 is holding you back. A nano ported 102 would do wonders for you

Also FAST came into a thread and explained why they phased the 92 out. They said it was such a superior design and retained the ability to take a 90 or 92mm TB so there was no need to keep it around.

I had a FAST92 when it first came out. Many people may remember but ported I picked up 32rwhp and 20rwtq from putting it on. Of course that is with a re-tune. I wouldn't even consider putting a LS6, BBK, or Typhoon on.

^^^^^^what was under that fast 92?!? Thats quite a ridiculous gain if you have a dyno chart I would LOVE to see that!

Well, now I gotta figure out where to get one from. Looks like I'll need some fuel rails and few other parts too.

Blk98Vert

Call around and see who can get you the best deal. The whole fuel rail, injector, TB and manifold should run you around 1300
