I went from stock plenum and the big rapid cooler!

Joe commanded 0 boost but minimum was 18psi once run up on the dyno!

I then Fitted the pro street cooler (smaller) and a plazmaman plenum! Commanded 0 boost minimum was now 13psi! Also power before was maximum 342RWKW at 18psi new cooler & plenum 385RWKW 16psi MORE POWER LESS BOOST

Tell me it was all the cooler!!!!!

Stock plenum is an absolute piece of garbage...I hate it with a passion lol.

400+kw and its garbage?

I understand that a PW /Plaz /Niz may be better but I wouldn't say the stock one is garbage.

I asked my tuner a while ago as I was ready to buy a Niz plenum and rocker cover and he advised me not to waste my money, so I didn't.

I will tell you it was both.

I don't believe it would have dropped 5psi and made more power by just changing the plenum.

Was the tune changed?

My point is it would not make more power then that! Even with 18psi! I aggree it would have been a combination of the two changes. But being such a huge difference the plenum had to of helped.

im looking for the 400+ I just put a almost new motor in my ba ... FG MK2 F6 bottom end with my recoed BA head with BA cams

iv done everything

the only things left on the list is a plenum and hot side pipeing..

at the moment im running 334RWKW @629.2NM @15PSI (with old motor)

Jason,

Your car for some reason has always made less power than others with similar mods, I don't know why.

In the E85 thread your Autotech tune had you at 344 @ 15psi with a standard GT3540, and with a standard manifold.

I like the FG one as it looks factory, can support 600+rwkw, shortens intake tract and was half the price of Plazmaman etc

Yes. The garbage can is where half of mine resides!
