I went to an RR day yesturday, the JMS kit made ZERO diference over standard.I'd get the JMS one if I were you, at least they've got rr graphs to show an improvement.
PH2 172. Virtually the same all the way through the rev range. Makes a nice noise though..Really, was that on a ph1 or ph2 though because ph1 airbox is really good anyway.
really ? is it that simple? I might give this a go...Just pull one of the cold air feeds off the airbox. Will sound nice and make virtually no difference.
Save your money.
yep what he said, i have a k&n filter, with the cold air feed unplugged, sounds extremely deep sounding! very impressive for free mod
I found that my car felt quicker with the standard airbox before the rest of my mods but I put it down to the fact that the flap in one of the airfeeds opens at a certain point and this would make it feel like a sudden rush but with no flap the full amount of air would be getting in right through the rev range and you wouldn't get the surge you get with the std setup
So it opens up at a certain rpm (which the above helpful video shows :S) which in turn will allow more air in but that won't make any difference? Surely if more air is coming in (within reason) then this should make a difference.
Incidentally I manged to get a 14.2 second 1/4 mile with a 'rubbish' Pipercross open ik in 28degs heat...with a standard I would have been in the 13's by all accounts lol
It is open at rest. I beleive it closes at high rpm for EU drive by noise regulations. Its not a throttle body as such.
It shows little movement in the video possibly because there is no load. I posted the video to show that its starting position is open, not closed.
Did you not run the same times with a CDA encolsed kit ? - your motors a hero of mine haha Epic engine
