Looks like Dark 50 has been reading his magazines again. All right 50, I’ll agree with you, Long runners create better low RPM power, & Short runners help the upper RPMs, but runner length has absolutely nothing to do with plenum volume! Geez where did you come from. Even if you read a magazine once in a while, you would learn that the plenum volume is a very importing tuning aid. As high velocity gasses flow through the throttle body, the plenum give the gasses a chance to slow down, as the velocity is reduced the pressure rises. Higher pressure means that the air will be more dense, and of course that means more power. As rpm goes up you need a larger plenum. Now runner length effects the RPM range at which your engine creates power. Take a look at the Cobra, the Cobra has tuned equal lenght runners that provide good power gains at the higher RPM ranges without reducing power at the lower end. Ok enough, just open your latest copy of your summit racing magazine, you do get one don’t you, there free. Anyway, look at page 35 and holy crap! There are 1” thick Aluminum Spacers for EFI cars claiming to add 20 HP, increasing fuel atomization, and increasing combustion! They even have spacers from TrickFlow (same page) claiming better power and throttle response, and improved gas mileage! 50 I don’t mean to pick on you, but if you look at those pages, you will notice that there isn’t one damn spacer for the Mustang Enthusiast. That pisses me off! So what I basically did was make my own, posted my results of what effects it had on my car hoping to help everyone out. That is what this board is for isn’t it? To learn from one another. Anyway, I just happened to be one of those people that wanted to try something new and instead of paying $80-$100 for a part, I thought I could save some money and pick up a few horses here or there and make one myself. It does work, and it’s the best $4 I’ve invested in my car yet! I challenge you to try it for yourself. I honestly don’t think you’ll disappointed. Anyway I gotta go now, 50 I hope that this post helps out. The one thing I hate to do is come in here and see people cutting each other down for their own opinions. I would never post an idea or thought if I didn’t know what I was talking about.
