The stock manifold will handle lots of power, but it's also a matter of improving the flow, especially when you are running force induction. The better you can get the air to flow the less boost you need to get to the power level you want. The Weapon-R manifold flows better than the stock one letting you get more power. If you're interested I've got one new in the box that I'm not going to use, my setup won't work with it. PM me if you're interested in it.

 

Does anyone know where to get the descendant manifold. I can't find it anymore and descendant racing had not responded to me.

 

I believe that they don't exist anymore

 

What setup are you running that the intake manifold won't work?

 

I'm going supercharged but not with the TRD p.o.s.. Eaton MP62 mounted on the backside of the engine where the intake manifold is. I'll have to build a custom manifold as I also need to incorporate an air-to-water intercooler.
