on a turbo car the boost will stay the same because the boost controller will look for its boost set point. well it should i run a Eboost 2. id really think a better intake would help my car alot. trying to make 800rwhp with my 402

i wouldn't think 800 on a 402 would be hard at all.. hell i hope to make more then that on a 347..

800rwhp with a unlocked 4L80 on a mustang dyno is alot too me lol.
just with pump gas. but the number is not a big deal just like to rock out a 9.50 pass this year

So your thinking there's not much to gain for me swapping intakes and not spinning my blower faster?

oh i beat it would help for sure. boost would go down but i beat it would make more power. thats what im thinking

I fought with my car all year since putting on the FAST 102-couldn't figure out why it slowed down so much.

Put the LS6 intake 75mm TB and ran my new best and set some new records too.

Not too many out there with that same result. I've only been looking at turbo based cars since they all left their boost levels at the same settings and therefore they in affect are adding more volume. With supercharger you'd need to change pulleys to get you back to your previous boost levels.

Boost is only a measure of restriction though, so how could you loose power if your still flowing the same amount of air? I would think you should see some gains just from the design improvements in the intake

That's a first. I've never ever heard anyone say this.


As far as the cost, you gotta buy a 90-102mm TB to go with it so tack on another $500 to the price. Personally, I wouldn't spring for it if I didn't already have it from before I went FI.

I don't have an eBoost but I was pretty sure that that controller works on solonoid duty cycle which means that the boost will go down if everything else stays the same including the controller settings.

your right cobra forgot about that. what intake is on your car?

I have a FAST90 with a NW 90mm TB. I took mine apart and removed all the rubber seals/gaskets between the 3 layers. I filled the channels with epoxy, put it back together and removed any epoxy that squeezed out so that all my runners are nice and smooth. It is now a 1 piece deal.

I think CobraKiller has a ported and glued together Fast 90

so do you think a 102 is kind of over kill? when do you think a guy should upgrade.

That's what I was going to do with the 102, but my concern was the individual runners-I have heard of them breaking over 24psi. Problem is-if you epoxy the top and bottom-you'll never access the runners.

Next step will most likely be a ported SV.

I've heard there is a man in the sewer that eats little children.. but where is the proof?!

lol^. Better flow = more power. The more efficiently you can provide for the engine, the more power it will make. I'm not sure on the losses down low but over all it will make more power. Bob at Brute speed did a before and after dyno test with just switching out intakes from a LS6 to a FAST 92 iirc and they picked up around 60 wheel I think. Boost pressure should go down but efficiency and over all power should go up. It's a similar comparison with a FI car and exhaust....less back pressure and greater flow = more power to a certain point. Cobrakiller, I'm assuming you haven't had any problems with the intake? I'm looking to upgrade from my LS6 and I'm not sure which route I want to go. I'll also be upgrading the heads and blower.

FAST 102/102 combo results for perspective, note its a t56 ride

That was actually going from an LS2 intake manifold to a FAST 92. We lost two pounds of boost but picked up 60 rwhp on the Mustang Chassis Dyno. You won't see these gains going from an LS6 intake as it is a much better design than the LS2 intake.

Here is a link to the car we did this on. Bob

I am curious on this subject. I have been kicking around the idea of going from my ls6 intake/ported tb setup to the fast lsxr 102/102 setup in hopes to pick up some power and get better throttle response. Anybody else done it and have actual proof rather than just opinions?

I'm curious if it would be worth the extra $ or would porting my 317's be a smarter choice power/money wise. Opinions?
