IVE SEEN A LOT OF PLENUM SPACERS FOR SALE.HAS ANYONE USED ONE AND DID YOU GET ANY GAINS FROM IT.CHEERS MARK

 

i think the flowseparation becomes worse with it

 

However the intake does get cooler hence denser

 

I bought one for my mate and he said that he felt a better response with the spacer fitted. Also the company(gns engineering) claims that you will gain more power! And they realy fit nicely!

 

im thinking of getting one,the one that follows the gasket line so it doesnt impede flow,best to get it mapped after fitting to make the most of the extra airflow

 

Lee cattermole TIB and MAD Rod tarry use them on here. I have seen them and really interested in them, especially if good gains are to be made.

What are the pros and cons on these, I would have thought it will help with flow as the plenum cover is so close to the trumpets?

 

for them to work propper the inlet "neck" needs porting,
on my saff its a 30mm spacer

 

*Bump*
Just to add to the confusion of the other thread :P

 

i have never heard of this term before. can you please explain what it is and how and why it happens when a plenum spacer is fitted.

cheers

 

i´m so bad at english so i skip the explanation

but it´s all about that you move the inlet flow from the throttle away from the trumpets
