Butterfly Plate issue?

I'm going boost this summer with my gsr. I have hondata s200 with a chipped p28 ecu already. I know with the p28 this means no butterfly valves for me. :cry: What can i do about this? Should i just get an aftermarket manifold? I was thinking about a blox manifold which would be better for boost anyways right? Is there some way to re wire the butterfly valves or should i not even bother and get more power with a blox manifold?

i think the butterflys hinder the gsr under boost, if i remember reading correctly. same thing with the h22's.
its better to just flow with the primaries and leave the secondaries not working. but i could be wrong. what are the specs for the blox im? runner length, diameter, overall stack

I know there was a guy with a neon that used a vtec controler to use their Magnum manifold design. (it does the same thing as our butterfly valves)

you could probably do something like that if you really wanted to keep them.

if that's the case then i will just remove the plate so it is open all the time. I will find the specs of the blox manifold....any other opinions? Dc2gsr where you at mang?? haha

I'm right here lol

I wouldn't just remove the butterflies and leave both runners open. It will create some nasty turbulance in the intake mani with pressurized air trying to fight through both sets of runners and that will hinder flow, especially at high rpm under boost. An aftermarket mani would definitely help flow under boost. I just wouldn't remove the butterflies. As for which manifold to use.....i don't know the specs of the blox off hand, but you would want a manifold with a bigger plenum and shorter, fatter runners for boost

go with jg edelbrock manifold for boost. i see skunk2 and blox more for na applications since they are skinny and longer..

what about using an ls manifold? Would that work? I looked into edelbrok manifolds and they're really expensive :( Don't get me wrong i'm not skimping out on this i'm just trying to find the best way to fix it.
