Ok guys i posted here becouse this is for FI i justwanted to know which one should i choose a plenum spacer or a plenum. For now my set up is going to be 7 pounds and custom exhaust just looking to squeeze the most power out of that setup.

I just want to know is it really worth spending all that extra money for a new plenum or just getting a plenum spacer. Which option and explain your self why i should go with it. I have a greddy TT. Let me know thanks.

 

read the plenum comparo in latest issue of sportz mag.

 

Yea i saw that one and the 5/16 was the best but im talking about personal experience or things you guys have heard

 

Personally I prefer a plenum, just one less flange surface to have to worry about leaking, you have enough things to worry about having a TT.

 

Its true what you say westpak. Has anyone had a leak recently.

 

Anyone else

 

We've yet to do any plenum spacers, but from our experience a plenum is well worth it. Adding a plenum to TT & ST cars, and retuning whatever EM you're running will give you a significant increase in performance.

 

Ive kinda heard that they are good but i wanted to know if the spacers really made that difference

 

Ssv

 

Thats the one i originally wanted to go with but ive heard to many comments both good and bad so i decided it was to much for a good/bad product my choices now are the 5/16 motordyne spacer or the new crawford plenum which ive always heard good comments about the crawfor.

I just want to know the people out their with FI induction what are they running and what has been their gains. I would really appreciate some help here please!!!!!

 

I got the Crawford cast plenum and very happy with it.

 

how much horsepower do you have now?

 

Still haven't got it dynoed I've been really busy but I'll have lots of time off this spring.

It feels like at least 400-415whp.

 

Nice dyno calculations right on it 15 +/- LOL


Normally when i make one i make sure itsa round 40+/- just in case.

I want to see im going to get my custom exhaust hopefully next week and ill see what happens with the plenum. im trying to find out ASAP becouse i have a tuning see and want to take advantage of it. Im going to try to get the plenum mod the exhaust and also maybe throw in a pulley dont know either on that one. But thinking on going with KJR.

Well anyone else go some imput in the plenum

 

the md 1/4 made 17whp on my hks sc kit, as i posted in another thread. as you know, there are other considerations when choosing a plenum mod like strut bar, hood, engine cover, cost, etc.
