I was wondering if anyone has tried either BJ's or Magnus's intake manifold. If anyone has some before and after comparisons and installation details (how much the upper intercooler pipe has to be modified, etc).

thanks,

bryan

 

i think Boost Solutions is doing a test on their demo car with 4 diffrent manifolds. i know they have the JUN and i think they are testing the BJ to. there was a theard under the name of "the fattest ladies" or something. very good.

Hope this helps. Chris.

 

pretty sure Al runs the magnus, told me that it took a lot of modification for the install though

 

hmmm I wonder if they are testing the new HKS kansai unit...

 

i dont know mate, not heard much on it recently. the HKS looks a very good piece of kit, although the JUN does look the best (and is reputed to give the best flow)!!!!

I got a bj's from mark at quantum-racing.com. Added 32 hp an a lot more up above 8k. Easy install.

 

32 bhp from a mainfold? that shows you how restrictive the stock one is at higher tunes (read higher flow rates). what figures where you running before and after? i hear that it only becomes a need after 500bhp!

thanks Chris.

 

i ordered the magnus last week. it's said to give a bit more down low due to the plenum design. i love jun, and have their cams already, but 3K for a manifold! come on........

 

Here is before and after adding the manifold with a roadracew conservative tune. I had a major wastegate leak so the turbo spools 25 psi at 3700...
