Either way you're right. I haven't seen enough data to justify the swap. If it can get into the same range as FAST 90 but cheaper.....I would be all over it. Not gonna do it for LS6 numbers. Already have that.

Perhaps it was the same car, i though it was a different post by a different user, guess not.
Anyway, I think thats the best thing. stick with the LS6 till people are really showing some solid gains. Although it could be the type of thing where it dosnt show much improvement over an LS6 on a stock motor, but perhaps a big heads/cam car, or a stroker could really benefit from the larger mouth. Foood for thought.

These are your numbers with the LS6 & the 85mm right? (from this post https://ls1tech.com/forums/showpost....&postcount=451 )
Even with the 85mm it still dyno's lower than the LS6? Sooo....added to what you just posted....
LS6 and stock TB = 383/371
85mm and 85mm TB= 379/361
Is this correct?

Now if you look at the throttle body, it doesn't really matter what manifold you bolt it to, its still going to give you a good hp gain. If you look at the price, the #'s, and the looks, I don't really see the issue here. It just really depends on what your looking for. Just my .02 Last edited by 02SS:ZEUS; Aug 17, 2006 at 09:47 PM.

That's the way I had understood it too, the gain was still there, the dyno numbers you posted today was a before/after TB but the numbers were lower because of a heavy rear install with shorter gears. Sounds like a solid gain.

I should be receiving my LS6 intake soon, and it's going to need a good TB. Were there any fitment issues or other quirks with 85 mm TB?

Screw it. I think I'm down for one. I've got a ported Holley intake and could use a larger and more affordable TB.
Anyway, I think thats the best thing. stick with the LS6 till people are really showing some solid gains. Although it could be the type of thing where it dosnt show much improvement over an LS6 on a stock motor, but perhaps a big heads/cam car, or a stroker could really benefit from the larger mouth. Foood for thought. This is very true. I have a ported Holley intake with a stock ported TB. I can't find the dyno sheets but I had an ls6 intake with the stock TB before. in stock form the holley intake dyno'd lower than the ls6, but I added lots of compression and a very healthy cam. Again I had it dyno'd at the same place to record my gains. Then I put the Holley intake back on and dyno'd again. I showed 14hp gains over the ls6 intake with the holley and stock tb.
Moral: If the intake is used with the right setup, and the application it was designed they tend to show better results.

They are. First off, the whistling problem only occurred on some Ford throttle bodies and was eventually solved by adding a chamfer on one of the internal holes. Secondly, we have since moved all of the production of throttle bodies to a new factory which is one of the largest throttle body manufacturers in Asia that produces O.E. throttle bodies by the millions. I would not be afraid to say that we probably now offer the highest quality aftermarket throttle bodies available.

I'm just giving you a hard time, Mr. Funny Bone. I know it's in development. And for that very reason, I'm waiting on your products. I just want to get the 96/96 so bad I can't stand it.
