Hi, I need some help here.

I searched for about 35 minutes and found nothing.

I picked up a spare lower plenum today, but how do I know if it is to a rev up or a non rev up?

I will post pics if i need to.


Thanks,

Mike

 

bump

 

great!

thanks for all the responses.

 

^lol they'll probably answer on a weekday. Or you can pm Hydrazine (motordyne), I'm sure he's seen a couple

of lower plenums in his day.

 

It would be best to post pic's, but I'll help you out. On a Non Rev-Up the intake
runners are long, on a Rev-up they are short.

The plenum on the left is a Rev-Up, the one on the right is a Non Rev-up.

 

^^ theres only one....

 

oh nevermind.... i see.. theres 2 next to eachother.

 

so which do u have retard

 

the right one i hope..

 

dude, you got the pics right there just compare

 

some of my old pix from when the rev-up motor came out and my experiments...

These images are watermarked with the company I was with before riverside infiniti...

This is the first dyno comparing the rev-up to non-rev-up plenums from tests on my 03 350z. You can see the gain in high end horse power and loss in low end horse power/tq from putting the rev-up plenum on the non-rev-up motor... in turn, putting the non-rev-up plenum on a rev-up motor will have the opposite effect, adding more low end hp/tq and less high end hp. by adding a spacer like the motordyne this will in turn add high end horse power to a non-rev-up plenum. and by modifying one in a way (like the MREV2 mod from MOTORDYNE) you can get the most HP out of the non-rev-up plenum on the rev-up motor. At the same time, adding the spacer to the non-rev-up plenum on a non-rev-up motor you add more high end HP. And adding the MREV2 manifold onto a non-rev-up motor you can get just a little bit more HP out of it...

 

well it looks like i have a non revup.. can anyone swap with me??
