does anyone here own a 06 Z and have installed a plenum....please give me a feedback and which brand you had bought and pic if possible thanks...

 

I have the Crawford on my 06, it's a great plenum. This thread has some pictures of it.

You looking for upper plenum? There's also the MREV2, which is a modified lower plenum from the non revup motor that helps increase torque in the revup (06) engine.

 

I have AAM angled plenum spacer on mine, got it installed back in Sept-06
You really don't notice much until you get on it at higher RPMs. The 06 models for the most part had the air flow problem to the front runners somewhat fixed. If you check AAM's website they even tell ya that the power gains aren't all that much for the 06 model with the spacer vs the 05 and below. I think it helps in the bigger picture when your trying to squeeze all the power out of your engine w/o going FI.

 

Right now the choices are pretty limited for revup. As mentioned above, spacer is little help, upper plenum alone is a lot like a spacer, so same thing. MRev2 + spacer makes a noticeable gain in tq under the curve, doesn't hurt peak hp, but doesn't really help it either, IMO this is the best solution out there atm.

I think the plenum with the most promise for us is the Cosworth whenever that gets released. Adjustable runners mean you should be able to dial this in for motor type and application, but the price tag will be up there.

 

From my understanding, its assumed to be priced at a little under a grand.

 

I recommend the Motordyne spacer and the Mrev2 kit.
