I've got a turbo. (Sweet!) It needs air. Clean air. It has a small K&N on it now, but it came off a 500cc 4 wheeler so I can't imagine the filter flows anywhere near enough for a turbo 1.8.

This picture shows my charge pipe routing going straight across where normal people put their air filter:

It also shows the tiny air filter I have, lack of heat shielding, and lack of heat wrap on the coolant lines. Basically it's a shoddy setup at the moment. One thing at a time I say!

I need ideas on what to do with the big K&N I have in the garage. It won't really fit anywhere under the hood, and I'd like to give it cold air anyway.

I don't even know what to give you for info, except that picture.

Ok, so throw out your ideas. I've got a little bit of leftover intercooler piping (2.5" aluminum), and some other pipes and couplers, but nothing too extensive. I'd like to use what I have but I will buy a little here and there if I need to.

 

How small is that snail? As for the filter, measure what you need and look it up on k&n's website, at least that's what common sense is telling me.

 

The snail is a 14b, so it's pretty small. Seems to flow enough for what I want, but I"m sure it's getting out of its efficiency range toward the top end.

As for the filter, I have a big one I just can't figure out where to put it because it won't fit in the engine bay. I really do not want to have to buy another one at $50.

 

Better to do it right the first time.

 

Ben was running a filter about that size or maybe a tad smaller on his car for a good while, and it was fine. IIRC he said it was on another car that put down 270ish WHP with it. So I wouldn't worry about the filter. The location of said filter is another matter...

 

I couldn't post a picture of my car if it was that dirty... DUDE, SIMPLE GREEN AND A SPONGE!!!

What's with the oil seeping out the oil cap?
Lots of fluid accumulation under the heater lines?

Although your filter is a little on the small side, it's probably fine. Think about how big your average panel filter is on DSM or MSM... if you took that cone and layed it flat, it wouldn't be that much smaller. But your real problem with that cone is that it's filthy. It looks like you have never cleaned it. K&N filters if they're clean should look reddish/purplish. I don't think I've ever seen one that bad.

 

You are all missing the point. That filter is borrowed, small and dirty. I need to give it back and I want to put the bigger filter I already have somewhere where it will get cold air.

I was thinking about running a pipe from the turbo over the radiator and down into the bumper. I'll have to crush the pipe a little to clear the hood, but I imagine I can rig something up to get an acceptable flow rate.

And yes, I know the engine bay is dirty... it's a work in progress. Get off my back.

 

IIWY, to find cooler air I'd try having the pipe reach down, and then toward the driver's side, to avoid the radiated (is that a word?) air.

No.

 

You never said it was borrowed kid, thanks for clarifying though. Why don't you just buy the correct size you need? If you are that cheap, then try the salvage yards, I'm sure some riced out Honda has one on it.

 

Well, I wouldn't JUST crush the pipe. I do have a little bit of knowledge of fluid dynamics.

People run their charge pipes over the radiator (sometimes) so why can't I run an intake pipe there?

And running the pipe down isn't an option. That's why my charge pipe runs through the fender. PS and AC made routing difficult.

 

pit crew front end, filter right behind headlight ftw lol

 

Charge is denser than intake.. That's why nearly every turbo car you've seen runs smaller charge pipes than their intake pipe.

 

fluid dynamics?

ME major by any chance? ive been studyin that **** all weekend

 

Yep. been a while since I was in fluids, though.
