Which plenum spacer has higher gains? The AAM angled spacer or the motordyne 5/16? I am ordering right now i decided to go N/a for now starting with spacer, popcharger, and true dual exhaust. But my fist buy is the spacer and popcharger tonight. Also I am getting the Carbon fiber intake tube for popcharger.

 

You reviewed the Sport-Z magazine Plenum vs Plenum Spacer Shoot Out correct?
What did you find?

 

^Don't remember the results of that, but I just did the MD 5/16" spacer and I'm very happy with it on my rev-up. Top end seems much better.

 

I'd look for facts (e.g., dyno sheets) than trust a poll. No offense, they're more opinion based than fact based.

Just my $0.02.

That being said, after I did some research (and I more than likely I missed something) I decided to get a Motordyne spacer. So far, so good. Still though, I have nothing to compare it to (i.e., another spacer), just how it 'felt' (no dyno sheet) w/out the spacer, so who knows.

GOOD LUCK!

 

I guess you can never have enough threads on the same subject.

 

I'm surprised these thread wasn't locked.

 

Then again maybe not. Good-bye friend.
