Professional Products Intake
Does anyone know anything about this intake?
http://www.professional-products.com...oldsLS1LS2.php
New Typhoon LS1/LS6/LS2
This unique new design features a larger plenum volume than stock or aftermarket manifolds, somewhat similar to the 2006 ZO6 manifold.This larger volume is particularly suited to big inch engines but extensive dyno testing on a stock LS1 also shows substantial gains, especially in the mid-rpm ranges.Tested primarily against a leading aluminum aftermarket manifold that is similar in design to the LS6, the Professional Products intake showed equal power on the top end with an additional 12 to 15 hp in the 3,000 to 4,000 rpm range. It was also tested against a factory LS6 and produced an additional 17.7 hp at 6,200 rpm on an engine dyno.
The manifold is available in three different configurations with each of the three offered in either a polished or satin finish. The first configuration is designed for the LS1 and LS6 engine. It features an 85mm inlet opening and uses LS1 style throttle bodies. The second configuration is for LS2 engines and features a 96mm inlet opening and uses LS2 style throttle bodies. The third style fits LS1/LS6 engines and has the 96mm inlet opening. This manifold requires an LS2 style throttle body but the fuel rails and manifold are designed for LS1 style injectors which are different from LS2 injectors and use different electrical connectors. This third manifold requires the use of LS1/LS6 style injectors and the matching wiring harness.
All three versions of the manifold come with custom fuel rails, a stainless braided -6AN crossover hose, an inlet fitting that connects to the stock fuel line, stainless steel fuel rail mounting brackets, and all stainless attaching hardware. Note that early (1997-'98) LS1's that had a fuel pressure regulator mounted on the fuel rails will require our optional #52160 regulator kit which includes a 25 to 75 PSI EFI adjustable regulator and additional fittings to incorporate the regulator into your fuel system. All three styles of the manifold also include nitrous bosses suitable for drilling and tapping for nitrous nozzles. Note that there is only space for a single tapped hole per port.

That's a loaded question
The lovers are going to tell you it works great with no issues and to ignore the haters, most of them have never used one.
The haters are going to tell you it heat soaks and fits poorly, and is heavy cuz it's aluminum
Visit the ls2gto forum, there are many there that use them.

You never hear about them on this site and the tax on the FAST is a bit high.

I've used their Typhoon intake on my car for the past couple of years. I decided on an aluminum product after I'd seen some plastic ones rupture when under boost or nos, and burn the cars to the ground. I will say this:
1. I did experience some fitment issues with the bottom plenum cover at first. I think I may have been one of their first customers, and this could have been birthing problems associated with a new product. Professional Products were very pleasant and professional to work with and they resolved all issues in a timely matter. They sent me a new manifold, and upgraded it to polished for my trouble.
2. I installed this manifold along with headers, ProCharger, injectors, and other goddies all at the same time, so I cannot comment on performance gains from their manifold only upgrade.
3. The intake has been on the car now for over 20k miles with zero issues.
Some people complain that it adds weight. Yea, it is heavier than plastic. Some people complain that it will heat soak. I really don't think that is much of an issue. BUT, it won't burn your car up, and I think that the small additional weight (probably less than throwing a case of beer in the back) is worth the rupture insurance.
I would upload a pix for you, but it seems that PhotoBucket is experiencing some problems this morning.
Good luck.

Thanks for the feedback! I am sorta going in that direction, and like you said, if you add a blower later it will still work.
