In the top 100 post, it says the best bet is the Motordyne 5/16" and MREV2 for gains. Was wondering if anyone has had either the AAM or Motordyne 5/16" spacer installed on their car and whether or not they both have the same gains?

Did you feel like it was worth the money?

I'm also planning on purchasing the MREV2 lower collector as well, but wanted to see if Motordyne offers a discount to my350z members or not, before I buy?

 

a piece of aluminum is all the same. buy whatever is cheapest.

Although I FULLY support Tony at MD bc he was right there to send me a new spacer when mine leaked!

100% customer service!

 

Cool, then I have my answer. Thanks

 

Hi Acidhex,

Sport Z Magazine (now Nissan Sport Magazine) did a comparative dyno test a while back and published the results.

The data from the test is shown in the link here:

I went with the 1/2 inch spacer and it helped me reach my 1/4 mile goal for the season.
