ok so guys with plenum spacers im looking to get a 5/16 motordyne plenum iv talked to the people and they offer 2 types

5/16" basic spacer kit

and the

5/16" iso thermal spacer

does the thermal kits help out alot or is it just a waste up a extra $50 ?

 

? any 1 know

 

I personally didn't do any tests or temperature readings. I just used my hand to feel the plenum and see how hot it would get after some heat soak before and after installation. Not a very noticeable drop IMO. The plenum went from burning hot to just barely too hot for you to keep your hand on

 

5/16" iso thermal spacer is the best, i personally dont have it but i met a guy who had it. the engine is not hot as it should be. this is one of the mod where you will feel the gain..

 

Sweet!

 

i got the isothermal

 

+1 isothermal, u will feel gains

 

this is what i like to here

 

have you ever considered the AAM spacer? I dunno to me it seemed a little thicker and better made.

 

Motordyne FTMFW... Isothermal 5/16th FTMFPAW

FTMFPAW = for the mother f''king pimp a$$ win

 

iso-thermal.

 

do you need mrev as well? both would be better?
would this void manfa warranty?

 

Search is your friend.

 

I did a bunch of temp readings with the beta version... Data is on Driver somewhere... I have it on home computer but I'm not at home right now... the temps are definitely lower with the Iso Termal kit... if you want the data you can do a search on G35Driver... or I'll post here later if I remember...

 

5/16 MD here.

Not Iso-thermal. I couldn't tell you the difference anyway. It lowers the temperature, thats all I know about that.
