Has anyone come up with a good cold air set up for this application?

CarNDrvr · 07-10-2002, 11:07 AM

The title pretty much says it all...has anyone come up with a clean looking way to get cold air to this filter? I am sure there is much horsepower to be found by getting cold outside air to the filter instead of hot header air!!

This seems to work ok, just need to relocate the battery.

Sorry about the crappy picture.

Misc. -
8" x 1" Thin Aluminum (Available at Lowes)
Misc. Bolts
Tie Wraps

Air Ducting -

4" Silicone High Temperature Duct Hose
Part # THESS-400 4" $82.99 Racer Parts Wholesale.com http://www.racerpartswholesale.com/duct.htm

Breathless Performance
Part Number 100-210(3) C5 Air Filter Red 69.99
(2) 4" SS Screw Clamps

Procedure:

On the passenger side rear storage compartment, remove the storage tray and the cloth storage compartment lining.

Remove the 8 Phillips screws supporting the storage compartment lid assembly and remove the lid assembly.

Measure and drill holes in aluminum bar to match holes in battery storage tray and mark and drill holes in bottom of storage compartment. Place battery tray in compartment, using bolts, and washer and secure aluminum bar on underside of compartment with nuts and washers. Mount battery with posts towards the drive shaft rather then towards outside side. Install terminal corrosion protection.

Drill two holes for battery cables in side of storage compartment for battery cable egress.

Measure, mark and drill to holes in side of storage compartment for circuit breaker.

Mount battery in tray.

Mount circuit breaker on side of storage compartment and secure with bolts.

Put black automotive wire protector over positive leads. Run positive lead thru storage compartment access hold, over c-beam (thingy the drive shaft is surrounded by and over to driver's side in front of rear wheels. Secure with tie wraps to existing wiring harness that runs over the c-beam.

Remove front battery access panel, remove front battery.

Use an electric wire fish tape to fish positive electrical lead through rocker panels on driver side and into engine battery compartment.

Run ground wire from negative top battery post, thru access hole, and ground to frame.

Do not remove original battery tray. Remove the back most bolt from the battery tray and use this bolt to support the new positive insulated battery post. Connect original battery post to new battery lead on the insulated post. Cover with provided insulating cover.

Tie wrap everything neatly.

Air Duct Installation:

Remove existing air filter from ATI unit.
For ease in installation, remove wiring harness from cruise control and two vacuum lines from cruse control to ease installation. Disconnect wiring harness for cable that runs along rear inside of forward wheel well.

Fish new flexible air duct under cruse control support beam, under master cylinder, and up and around into ATI air intake. Secure with screw clamp. Cut air duct to length. Install air filter to end of duct and secure with screw clamp. Place on battery tray.

Reinstall battery access panel. Reconnect all vacuum lines, and electrical harnesses.

The 4" silicone works perfectly with some snaking.

WOW...that's quite an answer...lol. Thanks for the deltailed description. Did you do any dyno or track testing before and after to see what kinds of gains you got? Could tou tell a seat of the pants difference?

Flame Red · 07-10-2002, 06:54 PM

No, I did not do a before and after Dyno. I just don't have that kind of $$$. Seat of the pants is so subjective. I just went by the theory that all that hot air coming right off the headers was not good. This setup does seem to make the air cooler as opposed to the stock ATI setup as measured by me trying to feel the temp of the area around the filter area before (resulting in burned skin) and after (no heat in the new spot).

It has gotta help. Nothing scientific tough.

krivera · 07-11-2002, 02:26 PM

WOW i was looking for a way to run my system i have the same issue! i have the headers not coated and i am getting plenty of hot air! MMM i might have to do that take the batery out and try this! i have a G-tech and i will take before and after times all on the same day so with the same weather and look at the difference!

SuperL98 · 07-11-2002, 10:54 PM

Not an easy solution, but I ended up with hoodscoops and moving the aircleaner up as close to the openings as possible.
I also fabricated an aluminum heat shield between the headers and the aircleaner. Wrapped everything in heat shield material.
More valuable info might be that with the aircleaner in the normal spot (like yours) on a 70 deg day the air around the cleaner measured 155 deg at speed and 240 deg F with the car at idle!!!!!
With just the heat shield the temperature dropped to around 120F at speed, but still climbs high at idle.
With the air cleaner up around the hood scoops, in the picture, at anything over 30mph the air temperaturw is about 10 deg above the outside temp.
I was surprised how effective a simple metal shield between the headers and the aircleaner was.

Haven't had a chance to evaluate hp changes, from the relocation, yet.
I've read 1% increase for every 10 deg drop.

CarNDrvr · 07-11-2002, 11:33 PM

That's good to know about the temperatures. Does that mean that at speed, it will make more HP because the air is cooler? Where does the motor get its air from in stock form? I really don't want to modify the appearance of the car like adding hoodscoops. Does air come in the back of the hood like a cowl induction? I wonder if putting the air cleaner where you have it would work with a stock hood?

lead foot 85 vet · 07-12-2002, 12:16 PM

Here's a quote from caroll super charging

question; can you remote the super charger air filter for a source of fresh air?

answer: You could but after extencive testing, we could not show any horsepower gains on a corvette from so doing. In fact our testing shows a slight loss of power from remoting the air filter. The supercharger is VERY sensitive to inlet restrictions. A fresh air scoop built into the hood is the only good alternative we see but most corvette owners are not interested in such a modification.

krivera · 07-12-2002, 05:14 PM

Yeah i was thinking of modifiying the hood but i dont know? mmm there was a guy on here that had a nice setup he was pulling air from the drivers side front wheel?

YES!!!
It is a win win situation.
what you do not want to do is create a restriction as mentioned. this will cut off the CFM and boost.

The supercharger is compressing the air which creates more heat, so what ever temp you can drop the incomming air, the boosted air exiting will be decreased as well.

A short cut for you to look. http://forums.corvetteforum.com/zerothread?id=282675

I have made this extra so I can get so much cold air in as possible

yep that is the guy i like his setup! looks affective????

Hey Tomas / CarNDrvr:

What model# is that K&N filter on your Procharger?

Yours fit a lot better than the one that came with my kit (7" long and hits the master cylinder). Thanks!

Tomas · 07-17-2002, 04:00 AM

Hello gcrouse

I was searching for the partnumber but i couldnt find it, but a email you the KN filter application and there you can find the partnumber. hope that will help

regards

Look at http://www.breathlessperformance.com/ It is listed under intake components.

Quote:

Item 100-210(4): C5 Air Filter Red.
VORTEX CLEANABLE FILTER

These filters have a internal velocity stack at the tip of the filter which not only increases filtration area but reduces turbulence giving a smoother shot of air into the intake.

PRICE: $69.99

It is the only I found that will fit. But it still does touch the master cylinder on my 90 when it was in the stock position.
