Professional Products Intake Manifold
I looked at pictures of a 98 and a 2001 and they both had the same little muffler thing on the crossover. We need a picture to know what the hell we are talking about.
Here is my engine, can I get one of your LS1 versions with the 85mm inlet and fuel rails right now (and use my stock TB), or would I need to wait on your fuel rail regulator thingy?

We don't anticipate any problems as our t.b. facory is probably the highest quality factory we have and we have never had any issues with their products. Assuming everything is ok, we would expect to have product to sell in 60 to 90 days from the end of June.

There was a time long ago when I thought I might be wrong but I was mistaken.
Two questions.
Will only Fbody 96mm tb's be made, or will there be a Corvette version too?
If I am replacing my LS6 motor with an stroked LS2, which version of the 96mm intake would I need?

Yeah my Z is an earlier '98 (production date was like Nov. '97), and I don't have a fuel return line either. I was confused when I heard that 97-98 had a return line because mine doesn't, lol. That would mean the LS1 F-bodies never had a fuel system with a return line.
I think I'm going to order the polished 85mm one and do a couple of dyno runs to see how much better it is over my LS6. I just need to find out which throttle body to use to go with it...I don't want to keep my stock TB. I'll post up some results as soon as I get some.

I received an email saying that it was a special order item that has no back out policy and no refunds. So i pmed byunspeed and asked when it was going to be availible. no response. i pmed him agian. no response. i then emailed him and agian got no response.
Please let me know what the deal is on my intake. i only bought it under the impression that it was ready to ship out.
thanks,
Mike

i pmed you from this screen name
Can you tell us all whether the LS1 85mm is shipping as I want to order one as well, but now I'm getting worried due to what blown90lx just said. If they are going to be delayed or something, can you please let us know?
BTW, on the polished versions, are they raw aluminum or do they have a clearcoat on them to protect the finish?

This 85mm version was tested on a h/c car against the Weiand and did well. The real test would be how it compares to the LS6 intake on a bolt-on car. It might prove to be too much intake for stock internals, like the Fast 90 is.
