Hey guys after searching for about 2 hours the only thing I could find was some opinions and no actual facts about this. I want to get the spacer first then get the mrev after. From what I saw 1/2" you can't put an engine cover which I don't care because I don't have on I just wanted to know if I put the 1/2 with the Mrev2 would my hood close? or would it cause problem? and I want to know does anyone actually have any idea with the Mrev2 what are the actual numbers between the spacers? I have seen a few Mrev2s with the 5/16s but nothing with the half inch. Could you please help me out in deciding on which to go with. PS I might be getting a CF hood later on after those mods.

Thank you guys for the help

 

you should really look at what tony from motordyne has posted and contact him for the most accurate response

 

Thanks bro do you know his SN here?

 

The hood will definitely close if you have the mrev2 + spacer without engine cover.

I think I read somewhere that the performance numbers are very similar, but i think the 1/2 inch puts the extra power somewhere else in the curve. Do a search for "motordyne 1/2 inch dyno" and see what you get, then compare to 5/16. You should see little to no hp difference. I believe the 1/2 sounds different.

 

His screen name is Hydrazine. A spacer will do almost nothing for you on the rev-up motor w/o the MREV2 added to it. The 1/2" spacer will give you more power at the top of the powerband and the 5/16" spacer will give you more power throughout the power band. Most people opt for the 5/16 because the power increase exists at the RPMs they drive most often.

 

So you guys think I should save up for the Mrev2 then the spacer?

 

yes, and get the 5/16

 

I believe MotorDyne sells the MREV2/5/16" Spacer as a package, installing them together is a better idea than separate. Tony has advertised this combo as worth 18+ RWHP or better so it's worth the $$!

Thanks everyone and thanks Gary as always great help.

 

Oh Gary I see that you have 1/2" spacer could I ask why you chose that?
