I will have to take some pictures when I put the intake on it won't let me down load the ones I have

I would love to see what a trailblazer SS intake will flow ported by Peak Speed Shop.... Bet its alot higher than what people think possible.

Was there any info on the ls6 intake flow numbers?

i was gonna volunteer my ls6 but as of right now its not looking good. to ship it to him for testing is gonna be nearly a hundred bucks each way and i cant justify that much just for shipping. then again the place i normally ship through like to be a bit zealous with the packaging so im gonna try and get the package size down and see if i can lower the cost. A LOT

To the OP, when are you expecting to perform dyno tests on these intakes. Sounds like your trying to get things ready, and the comparision on flow #'s looks promising, but ultimately running them on the dyno and looking at the curves is what I'm chomping at the bit for. Literally waiting to see them before I order one of these.

IMO the best budget intake for a LS1 is the BBK with a 3 bolt 85mm throttle body, it's been proven in dyno tests, and it won't crack. If your car already has the LS6 intake, stick with that or jump to the Fast 92/102 or the MSD.

If you have a car with hood clearance then the Dorman Truck intake or the Fast truck intake would be worth considering.

I'd suggest the DLS2 for replacing a factory LS2 intake.

I thought the BBK did surprisingly well in the test

I think that the BBK has potential, but you have to think outside the box a bit. It's a very short runner intake. Most of the intakes have runners that are the length of the valley width, and they are curved around, etc. The BBK intake runners are only about 3-4" long -- JUST long enough to reach the plenum, and the plenum is huge by virtue of not having all that runner material in there.

it tends to be thrown onto stock internal motors, which can't really rev high enough for shorter runners to be beneficial. That it is aluminum and heat soaks doesn't really help it, but it is strong vs composite.

I suspect it would shine on a wide LSA cam, boosted, high rpm motor.

Getting Phase 2 of the flow test set up is going slower than expected. My 99TA required "hot rod" maintenence (new valve springs & 10 bolt rear end replacement ) that seriously dented my testing budget.

ERL had that big fire sale. ERL helped me spend the rest of my test budget

As a result Phase 2 still at least several weeks away. I also bought a surprise intake to test I think I will be able to borrow a couple of others for testing too.

While I would love to do an engine dyno test for all of these intakes that's not within my means to fund at this time.

For the price I think a used TBSS is the intake to beat. For $160 I scored one with fuel rails & injectors. I've seen TBSS as low as $100. While its ugly unshaved it does deliver good results if it fits. I would love to test a professionally ported TBSS.

Well gang, we will all be patient while 99 Blackbird T/A gets ready to do what most of us can only wish for. Good times ahead.....

I put a BBK on my stock head/cam TA. From what I've read the runners are about 1 inch shorter than the LS6 runners and the plenum is huge. It feels stronger from about 1500 rpm up. More mods are in the works.

LS1/6 runners...11 inches
BBK runners...10 inches
TBSS runners 9.5 inches
Professional Products runners...8.5 inches
(as per HOT Rod intake shootout)

I don't remember those runners being that long at all. the bottom of the intake opens up. i remember them being very short and stopping dead at the plenum.

I measured the BBK runners across the top of the intake and came out to about 13 inches so 10 inches internally seems about accurate. I'm not sure how you measure runner length, do you measure the long side or the short side or both and then divide by two?

I must have had a different model. The only way my runners were ten inches was if I used the same ruler that gave me a 18" member.
