: Another Cyclone Question

11-29-2006, 07:24 PM
Okay, I've searched feverishly for an answer, but everyones questions that have been answered don't really help me. It's probably been answered before, but I was wondering how bad running a cyclone intake would be for a non-properly actuated setup. I'm just about to get ready to start tuning and dialing everything in on my project here, and I was wondering how big a deal REALISTICLY running a cyclone intake would be if it was completely not hooked up correctly. I know there are several other methods of actuating the butterflys, but until I get an aftermarket intake, will I be cool running this? What I'm asking is if there is any serious reason NOT to aside from the differences in top end power.

I would imagine that it would only hurt top end slightly. I'm not 100% familiar with the cyclone but from what i understand it's got a secondary port that opens at high RPM's where it needs the extra air.
Correct me if i'm wrong.

Aside from your top end suffering there is no reason not to run this manifold. I can't see why you wouldn't just pick up a second hand 1g manifold and be done with it. I'm still a firm believer that the Cyclone manifold is a waste of time properly actuated or not.

Yeah^ I agree. I just wanna take my first drive in my car before I start taring off my intake manifold. I've driven in both stock cyclone intake equipped 1g's and other wise, and I didn't feel any difference. Just wasn't sure how big a deal the butterfly position would be. Should I just leave it all unconnected like it is now, or should I somehow fix the butterflys in the open or closed position?

The butterflies are open when the gate thingy is not connected so in that case it should be just like a normal 1g. They close only under vacuum.

Then whay are people always trying to actuate them? If it's like a 1g regularly, and actuated it suffers, than wtf? Anyway, I'm just leaving it the way it is. Thanks guys.
