anyone have a motordyne 1/2'' plenum spacer installed in their Z?? how does it sound and could you notice and hp gain?

 

I have a 3/8ths in Motordyne plenum installed on mine and I love it. Tony is a great guy and runs a great business. I did notice that my exhaust got louder but there is a definite HP gain.

 

Study the dyno charts published by Z Sport magazine. All the data is there. BTW you might change your mind and get the 5/16-inch spacer.

 

Are they on the Z Sport Mag homepage? I don't have access to their past issues but I'd still like to know why 5/16 over 1/2?

 

I would be very interested in that too.

 

He said that so you can keep your factory strut bar. And the 5/16" makes 95% if the gains of the 1/2" and is much stealthier.

 

I have the 1/2' spacer and my factory strut bar, 350evo did the install for me and just put spacers under the strut bar and it fits fine, sounds good, gave me a decent gain, and the 1/2' is better suited for my future goals than the 5/16'.
