What is the difference between Carwford, Motordyne, Plenum(or any others)...I don't know which to buy/install???

 

Crawford makes plenums. www.crawfordzcar.com .
Motordyne makes spacers for our G's, either 3/8" or 1/2".
A spacer would fit between the manifold and the upper plenum. Did you happen to check out BALZZ coupe at the meet last Sunday? He is running a 3/8" spacer.
Basically what a spacer will do is raise the upper plenum a little to allow more air movement within the plenum.
There are many different kinds of plenums you could get for your G, such as Crawford, Kinetix, APS etc...

Hope I have helped a little Burnt.
See you at the next meet.

Cheers

Search around a little on the board. There are lots of posts regarding all of this.

 

Yes I did...I'm thinking of getting it done, too...I just have to do a bit more research on the diff b/w a spacer and a plenum...

 

you can also get a 1/4" spacer....I should be recieving my 1/2" spacers and Hood spacer from motordyne tomorrow, I got in on the GB for $170 plus $20 for the hood spacer!
