Professional Products Intake Manifold
All of our LS1 and LS2 manifolds are the same price. So whatever the retailers, like Byunspeed, is getting for the manifolds, the 96mm LS1 model is the same price. The 96mm throttle body will probably retail for somewhere between $200 and $250. We haven't priced them yet so I don't know exactly.

i thought this about intake manifolds, not heads.
For those of you who want to see the 85mm Professional Products manifold numbers vs the LS6 manifold, you will have to search this thread. Its in here, I know, because I put it here. I have an 85mm PP manifold in my car, in which I replaced my LS6, and did dynos before and after. I have already posted the results once, you just have to look for them.
Now, I have news reguarding the Professional Products 85mm polished throttle body. I've been talking to Jim Davis with PP for a while now, and I happen to get my hands on the only 85mm throttle body PP has right now. So today I got in a few dynos with the new t/b against my stock t/b before I reluctantly sent his t/b back. This is a very good piece. I bolts right up to the LS6 manifold, or others like it, and looks very nice on there. Now for the numbers. My mods are in my sig, in which I must point out the 12 bolt, which eats up a little extra hp than the 10 bolt, so you could add a couple of horses and torque if you are using a 10 bolt.
---Stock Throttle Body--- 366rwhp 350rwtq
---PP 85mm Throttle Body--- 379rwhp 361rwtq
The numbers don't lie. +13rwhp and +11rwtq through a 12 bolt with just a throttle body! One that costs just over $200! I don't work for Professional Products guys, but this could be the best LS1 throttle body available for our cars, not to mention one of the least expensive. Now before you jump the gun, these things won't be available for about 60 days...and I got dibs! lol
I'm curious as to what your car would dyno with a FAST 90 setup on it actually. Sounds like your 85mm combo already netted you almost as much as the FAST 90 setup would and its half the price!

These are your numbers with the LS6 & the 85mm right? (from this post https://ls1tech.com/forums/showpost....&postcount=451 )
Pro.Products/Stock T/B=377.76 RWHP--363.79 RWTQ Around 95 degrees and just as humid
Pro.Products/BBK 80MM T/B=380.85 RWHP--370.81 RWTQ
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?

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.
