Gen II Hemi Blower Manifold

Gen II Hemi Blower Manifold - 05/28/17 04:06 PM

Looking for any input on blower manifolds (fitment etc). I have zero experience and it seems like there are a few to choose from. Indy has a couple, Stage V, and other blower shops. Any feedback would be appreciated.

For what blower?

I would think injected or carb would make a difference also.

Either going PSI or the Whipple 8L. I am going injection (E 85). From what I understand most of the time you want to inject above

That's right - those rectangular tops that you see on most Gen-2 manifolds are not what those Pro Mods use, because that's not where the air goes.


Very interesting! Thanks Polysheric!

Is the PSI roots or screw charger? From what I have been told a screw blower moves the air completely different than a roots. A roots constantly pushes the air to the front of the case and it tends to come out at ruffly a 45 degree angle. Thats why you see a lot of racers moving the blowers back on the manifold. Even the newer blower are moving the rotors future and future back in the cases. The big roots blowers do have a triangle shape bottom. Each manufacture is probably a little different position.Those blowers are for purpose built race cars. Is this a street or race aplication>

That looks like a nice piece. Did you purchase it yet?

Mostly a street car. PSI makes both but I will be using the screw if I use them. There have been a few people that have had luck with fuel injection and the C rotor believe getting it to behave on the street.

Not yet
$1100US which will be about $2000 with exchange and shipping by the time I get it in my hands. My car will be street/strip running a 14/71 standard Littlefield.
