I know I actually mentioned your testing before I ninja-edited my post. In my opinion 9°f isn't "significant" when people make comments about engine longevity and "gobs and gobs of power loss". I respect and support your testing, but I think overall the hatred towards "warm air intakes" on this forum is pretty funny.

9F is tough to quantify without knowing how the DME pulls boost based on IATs. Honestly, methanol and nitrous are so effective at cooling that it is a moot point for me now.

Looks great Chris!

Nice work, Jon/666!

so true that its not even funny!! lol

Of the fastest BMS and PROcede cars, who's actually running a CAI? I'm not sure, just asking.

With regard to the intake, I think it's kinda cool if you're looking for the fabbed look. DCI is ugly too (which is what I run) but it does the job to let the turbos spool up easier (so they tell me - and it sounds cool)

9F was when I was fully modded but no nitrous or methanol. For those without an FMIC the difference could be closer to 17-20F and that is significant. For the light modders, the CAI is definitely a better choice in my opinion.

this nonsense about sucking in hot engine air...do you guys even realize that our turbos run at 1050C (1900F) when the car is warmed up! EVEN if the engine bay were at a scorching hot 100C (210F) it wouldn't change a THING...that ambient/engine bay air will go down to the turbos only to be heated to crazy temps and then to be air-cooled back down by the FMIC...naturally aspirated engines different story...main thing about intakes on turbocharged engines is the capability to provide a good volume of filtered air that's all, temps dont matter

dzenno, that is simply not true and my testing proves it is not true. I am not just saying what I think, but what actual data showed in a control test.

Have a link to that thread? I just don't realize how it's possible (theoretically) to have a difference there..might be because the air goes through the turbos too quickly to be "significantly" heated..

You bet.

hot sides of turbos run at those temps, but the cold side doesn't heat so much. i do not think those temps exceed 85-90 C . and the sides of turbocharger don't interact between hot and cold sides so much. so 9F is still a good difference. it's like saying 350 whp isn't significantly different to 365whp. like "who cares if nitrous gives a hundred shot" ...

Cmon when you gonna hit up the dyno? I wanna see the results, as I have some people interested in it. I already talked to Jon about it....waiting anxiously...

[Trojan4evr]

OP, Props for givin it a try.

I don't get why someone just doesn't make a Dinan-like intake, but make it out of injection molded plastic. New lid, snorkel, cone filter.

Some company could make a killing.

Or maybe we could ask Steve if he'd create a less-expensive version without the CF?

A32, get Jon to wip you up a new tubular exhaust mani w a HTA 35r stuck on the end..........

[techlogik]

Kind of reminds me of the Audi S4 2.6T Y-Pipe APR made.

Looks like HVI or half a stett intake... thats where the coupler goes and the rest goes in the fender. For track driving... the CAI makes sense, but for straight line red light racing...shorter the better. I wanted to get this type intake but dyno's showed that they performed poorly. This appears to have a much smoother transition so may address some of the resistance of similar intakes.... Id love to see a dyno! Id love to see it produce! I have already made provision to push air to that same spot for the HVI set up but that intake has only poor reviews despite the access to cold air and the short configuration..

[nebz]

looks like a shorter version of UR CAI
