anyone believe this manifold can deliver 15-20 whp horsepower over a stock manifold...have any of you gotten this intake manifold yet for the gsr...for 595.00 with the optional porting it better...whats your take on this intake by JG

 

Any picture??

My guess will be on a stock engine, you will be lucky to see 5 hps increase. It may able to give you 15-20hps, but it won't be on a any stock or mild modified engine for sure.

the intake runners look really short and the plemium is large.............looks like it would be good for high-end HP but i dont think you would gain much low-end power with that........10-15HP over a stock intake manifold? i'm sure it will from 7000-9000rpm............ but how much power will you gain or loose from 2500-6500rpm which is that you need for everyday driving........i think for the proce a Skunk2 manifold would be a better choice......

but then again what do i know.......

 

i agree for the price i would go with the Skunk.

 

That manifold is better suited for FI.

 

Obviously that is not my car.

 

Would it be worth it in a built b18b bored to 84.5, never going above 8000 rpm? This motor would also be running high boost.

Would this manifold compair to the Venom, Hp, STR style? Or would just a ITR Maniflod be best?

 

the manifold is big. I saw it on some guys car who works for jg. He has ls/vtec w/ a gsr head and he is making 194hp to the wheels. He has other stuff besides the manifold..like ctr pistons

 

id wait and see more results / bugs before i purshased one.

 

Attention!- The JG POS manifold if for turbo only ok?
If your going N/A quit talking about it and get you a Skunk2 or R manifold.
