Default Turbo intercooler in place of aftermarket intake

I have a question I've been thinking about for a long time. Is it feasible to install a turbo intercooler without a turbo (probably add on later)? Taking out the hood scoop panel and using the intercooler like an aftermarket intake system? I know this sounds funny. Has anybody done this before? Will this work better than the aftermarket intake system?

An intercooler that uses outside air can't cool the charge below ambient temperature. Its purpose in forced induction applications is to compensate for the heat of the intake charge that goes along with it being compressed (the compression raises the temp hundreds of degrees). A normal intake will be better.

Got it. Thanks so much for clearing this up.

Talking about aftermarket intake, which is best in performance for the money?

GanzFlow with a K&N filter in the stock air box.

Don't want to step on any toes...but...

Best bang for the buck would have to be the PDM Racing intake. Pretty much identical in specs to the Ganzflow, but cheaper to begin with, and now with the piss poor Canadian currency it'll be even cheaper for you Americans.

i believe this has been discussed before. someone mentioned that a muscle car guy used an IC after the intake and found small gains. or something to that degree. the consensus was that its a waste of money.

I really prefer the GanzFlow because it maintains the stock airbox and that has an extremely positive effect on throttle response and low end performance.

bsquare: That's what the PDM Racing is to. Like I said, it is virtually identical to the Ganzflow. In fact I think PDM was the first to run with a 3" cold air pipe.

Despite you guys arguing over which is best, I just went out and made my own homemade intake. All I need was 10mm and 11mm sockets, socket wrench, flat head screwdriver, scissor, 4" hose clamp and a 3" flexible/extendable aluminum dryer air
duct. Pulled the aluminum from the airbox to the fender
and all the way to the bumper's air duct under fog lamp. I hope
mice or birdie will not nest in there overnight.

I'm missing a K&N oem flat panel filter though

Thanks Keiho, I didn't need the extra GanzFlow customers with the US economy doing so well

Truthfully Anson, no-one here can answer this. Why don't you try it out and report your findings to us. We can decipher and theorize why we think it will or will not work but in application on a normally aspirated Scooby, we don't know. It may very well be a good idea for some miscellaneous reason. So go and try it out and let us know what you think of it. I'm sure no-one thought that a 2.5RS could gain 15hp+ from just an intake change.

Sometimes you just never know until you try.

And yes, someone here as already did something similar to what you are talking about. They didn't use an intercooler but the stock intake air plenum housing. They cut the top half of it off and installed a filter of sorts over the bottom half. It got pretty dirty (they had pics of it on here) but they liked it a lot. I'm not sure if they were the only ones to do this modification either. Good luck!

Larry: No worries...I'm sure people will still buy from you anyway. I know I would if I lived in the States, less hassles with customs/taxes. I most certainly didn't mean to "take customers" away from you! If I came off as that I apologize.

Here is a pic of my 3" PDM intake:



It looks great, fits great, and sounds great.

Kevin,

Yeah, I've thought of trying that out but Bsquare said it's not feasible. Scroll all the way up and read his post and let me know what you think.

An intercooler is not cheap though. I will keep trying to find a bargain intercooler though. Will let you guys know if I do have a chance to try out this experiment.

Anybody got a intercooler lying around collecting dusts?
