I'm looking to get the shield by itself, similar to the K&N or Exotic Speed. I ordered a Blitz snorkel and CF arm, but can't find just the heat shield to go around the filter. Any ideas? or would it be best to use the stock air box with a drop in filter with the snorkel and arm to eliminate any heat problems?

 

OEM intake box is the best. Second best would be the Stillen setup. Bad thing is Stillen won't sell just the heatshield.

JWT heatshield is metal so it feels like it draws more heat.

 

I've fabbed custom Carbon Fiber heat shields for previous cars, and I feel like I may head down that same road again. It's just a PITA!

I'm in debates if I end up going that way to make the entire intake arm then, including the MAF port rather than having multiple tubes with more couplers cluttering things up. It would look much nicer with a single arm going into a CF box.

Looking at some of the CAI systems out there right now, are people getting more air from behind the bumper or in the wheel well? I suppose with a custom molded air box, I could run the snorkel in the front bumper and another port into the fender well. Any ideas?

 

It's from the bumper. The air travel up through the air dam and is pressurized through the opening next to the headlight. There is a snorkel made already to channel air more efficiently.

that should be it.

 

I think too much is being made on the amount of "cold air" going into the intake vs. the actual power gained.Yes,the K&N has a box per se as does the Stillen.If your concern on the Popcharger heat shield which I believe you can buy seperately is heat conduction,
just insolate it and maybe cover with a .5mm carbon fiber sheet for looks.

 

I made one out of sheetmetal. Real easy to form. Just made a template out of cardboard. It has two bends kinda like a Z and I just spraypainted it black and bolted it on. I would give ya the dimensions but I threw it away a year ago. Good Luck though!

 

I'm in the process of getting a carbon fiber one made by Blitz for that

I was looking to separate the filter completely from any under hood temperatures similar to the Stillen/K&N

In my previous cars, the CF dissipates heat quickly and helps with the removal of heat soak.

Sheet metal still absorbs a lot of heat. I may use something like that for a mold, but I will have to look to see how much room I have. I'd like to have a more direct air flow rather than shooting into the air box from the front bumper and then having to redirect because of a cone filter. I think a drop in filter would work better to keep air flow parallel keeping the CFM levels higher as well.

 

Man,I'll bet that CF unit from BLITZ is pricey...
As I said,I'd get a POPCHARGER heat shield,cover with CF.
PROTECH COMPOSITES(see them online)has sheets available with adhesive
backing good to 300 degrees.5mm cut with scissors,apply.You could even easily fabricate a box or,partial box out of light metal,rivet it&cover with CF.
Would look custom!

 

So what do you plan to gain from this? Heat soak is not an issue, not much we can do. AIT between a CAI and a JWT is identical, pretty crazy, and the air going in the motor is between 8 and 10 degrees hotter than ambient. Not much for gains in this area.

BTW is the car being set up for roadcourse, autocross or lame *** drag racing?

 

Acutally, got it off a guy that sold his Z before he could use it, $100. I'm looking at doing the intake arm in Carbon Fiber and the air box in Carbon/Kevlar. Just need to figure out a way to work in a drop in filter really.

I'm going to attempt to increase the actual air flow using a larger diameter/less restrictive intake track with a drop in filter (similar to stock) and see what happens. If it doesn't work, big deal; but if it does, then I will be the only guy with it and it will be a unique thing on my car.

It's being set up for my own person happiness, whatever that may be.
