I have an 05 Sedan RevUp 6mt and wanted to find which setup provides more power.

1. Motordyne 5/16" Plenum Spacer + MREV2
2. Crawford Upper Plenum

From what I have been reading, I can't installed all three due to hood clearance issues. I wanted to get your opinions. Thanks.

 

There was a post similar to this the other day. The crawford and the spacer would give you the same increase.

Go with the spacer and MREV

 

The most verified gains for your RevUp is going to be MREV and the 5/16" spacer. The crawford will work but the two never were developed together. I have the crawford and plan to use it with a MREV type lower on my on RevUp. But that's because I just happened to get a crawford at a great price.

 

did anyone figure this out? want the info but dont wanna start a new thread...i know how some people feel about that.....

 

Did you read the posts answering the question in THIS thread?

 

lol your right that was answered but im looking for dyno proof of it going either way...

 

Not gonna happen.

 

Motordyne advertises the MREV2 & 5/16" spacer to add 18 whp and as Tony mentions it will likely be higher. Crawford can't come close to that, Tony's word is better than any dyno test....Gary
