I'd love to have a slightly cleaned up version of his intake.

I know prototypes are known to look a bit rough. But now that hes done one, the next/others could look better.

Yes, I agree. I am working on another intake now. It sits about 3" higher and eliminates the nasty curves.

Yes, the time was on a 100 shot and that was with the slipping clutch so it does have more in it.

Last, I sell 3rd gen parts for those of you that don't already know. I tried to become a sponsor here but I was turned down. The only thing that the powers that be suggested was to put it in my sig and post alot. Right now, I am parting out a 92 Firebird w/ 3.1L V6 and an 89 Formula with a TBI 305.

Thanks for the support,
Jim

It will sit 3" higher and it will not be as wide so I will be able to pull the valve covers without any problems. If I had to compare it to anything, it will more resemble the runners of a TPI setup. I was considering doing that the first time, but it would have been more work (and money). It will be going on the 2nd version of my 3.4L.

I don't have any yet to date. I was going to dyno the different intakes after I finish the second one. N/A and n2o.

One a second note, I have a December promotion going on for members of firebirdv6.com, that I will also extend to members of this board:

Yes, the stock intake is a major performance killer. The only reason I did the turbo over the intake first, is because I figured the turbo would yield more power than the intake

Ditto. I think we won out on that bet too

All I know is, If someone builds one that fits under the hood, is reasonably priced and can be used in place of the stocker, they should market it. That stock unit has a runer cross section of about an inch...needless to say it's not tailored for a 3.1, and darn sure doesn't have the volume to support a 3.4 at higher RPM.

The only other problem is those who run STB over top of the intake. There isn't much room with a stocker one and a STB.

Though I have always been for products that function better then they fit. If ya had to run a cowl hood for a decent flowing intake, then so be it.

Good point gumby.

I'm not seeing as how 3" higher would fit under the hood though?

Wish somehow the 3.4 intake would fit around the distrib.

Well you know what I mean. Even if you have to fab a whole new hood, so be it.

I like them big fart can intakes.

That 3.4 Intake isn't much better than the stocker. I looked into modifying one, it's mre effective to use ours.

Not sure if Id have the never to post a pic after it was done but wonder what could be done with some 5-6in PVC pipe.

Two pieces 6-8 in long. End caps on one end, a 2 into 1 Y on the other end. Make some sort of adapter for the TB to mount on to the end of the Y.

Course a stock hood aint gonna shut. Would have to run hoodless for testing.

So no one had really said...does anyone think that if I got the blasted stock plenum, runners, & lower runners extrude honed, that I would find any signifigant gain? Also the box style I have seen some make here would reduce torque numbers!? The stock plenum has runner walls inside. Also, I like the looks of our stockers and was trying to keep the more surprise factor. Look under the hood see stock looking "Prettied up" engine...but dyno numbers and 1/4 say different...effect @ shows! PLus I worry about clearing the STB as well!

It will fit. Dimentionally the 3.4 block is the same... I'm running the BMR brace...only rubbing, I believe, because the Suncoast hood a little less clearance then stock.

If I Can pick up say 10Hp across the board with an intake that won't fit a STB, then I can certainly do without one. I don't have one as is, mainly because I can pull hard enough around the corners as is. I'd ratehr be fast than corner better
