The JG only provides gains from 7000rpms and up. So unless you rev out to 9000rpms every chance you get, or plan on putting this on a dedicated race-only car, it seems like a waste of money to me. I'll stick with my skunk2, so I can actually benefit from it during 90% of my driving.

 

I think there's a pretty simple decision to be made from the JG and the skunk2.. The skunk2 would be much better for a street car IMO. With the JG expect more lag and decent losses in the low end and midrange. For a street car this would suck imo, that's why I've decided to stick with the skunk2. This manifold works well at high rpms for boosted cars. The torque curve holds out longer = more hp. For na cars this manifold doesn't seem to work, the plenum is probably just too large, and the runners too fat and short.

So basically for a nicer powerband I'd stick with the skunk2, and for all top end, the jg is the way to go.

unless ur sponsored i dont see u keeping that POS tb for long...it sticks like a bitch

 

what about an Extrude Honed skunk mani???? any opinions on that?????
how about extrude honed jg mani???????? anyone????????

 

So why do you think that about the manifolds? The only ones using a flat plenum wall is a sheet metal manifold.

 

Actually on my Venom intake it goes like this |____\
