Hi Everyone,

New to the forum and have been enjoying learning from all the info available on this site. I'm wanting to add another 10-15HP. Reading lots about the plenum spacers. Considering this bolt on, perhaps. But is there any performance difference with the revup plenum against the non-revup plenum?

If there is, any idea on how much hp more it can produce?

BTW, what's a good price on a used supercharger? Thanks!

 

For an 04 a 5/16" spacer is the way to go. I don't think the revup lower will make any additional power on the older motors, revup motors gain power with a swap to the mrev plenium which is similar to the non-revup lower

 

Peoria is right!

 

To add to Peoria said:

Spacer would be the most cost efficient gain for you. If you want to eek out maybe a couple more hp from what I read, you can install an MREV2 ( modified lower NON-revup plenum ). But they aren't cheap

 

Thanks everyone! I know this is like reviving an old thread for the 100th time but I wasn't sold on the plenum. Pretty sold on the spacer.
