I have an H22a1 and I want to know which will give me better gains. The Short ram of cold air. Any suggestions on switch will give me better gains & risk involved for the cold air intake. I know cold air has a common hydrolock issue. Is there really any difference in performance. Thx I checked the FAQ and searched didnt find anything.

A short ram intake will give you better throttle response, since the air doesn't travel as far through the tube, so it will give you better gains in the lower end.

A cold air intake will give you better top end gains.

The only risk in a cold air intake is hydrolock, but if you get the AEM bypass valve, that solves the problem.

 

search man been 1000's of threads about this but a cold air is better but there isnt much difference

 

if you hydrolock your motor by sucking in water through the intake, then you have no buissness behind the wheel of an automobile in the first place because you clearly have no common sense.

go w/ the cold air, and stay away from deep water, streams, lakes, rivers, and ponds.

Well, for one the air is already inside the tube regardless of how long it is. Throttle response is about the same...you can stick the filter right on the throttle body and it doesn't make much difference.

 

hey buy my brand new AEM cold air intake! $175.00 plus shipping. i'll also include a bypass valve.

REALLY?!

 

The length of the tube does affect throttle response. It's the same deal behind the length of the runners of the intake manifold.

Short ram really doesn't offer any gains because it's drawing hot air from the engine compartment.

 

You say that, but the H22 in my track car made better mid and peak WHP with an AEM CAI compared to an AEM V2. Same day, same dyno, about 10 minutes apart. No tuning was done for the V2, though, just the CAI (NepTune).

IMO, it's difficult to say which one is "better" as all the parts work together, so what works good on one engine might not work so good on another.

Has anyone actually datalogged the IAT with a CAI and SRI? I'd do it, but I don't have an SRI to install...

Yeah, I drove to Austin once with just a filter on the TB and I didn't notice much...maybe a bit less power all over the RPM range cuz of the heat, but that was about it. Just a butt-dyno though

But it allows more air than a stock filter would, so it does offer some gains over stock.

The runners on the IM are after the throttle body, which is a bit different that a tube on the other side of the TB. Plus the runners go directly into the cylinder head so things like diameter, length, surface texture make a lot more difference. You can tune the runners so that the pulses from the valves bounce off the plenum and come back at the valves when they open and push more air into the chamber. Intake tubes can't do that.
