Removing air filter/box at track?

[BradC]

I'm going again in a week and I was thinking of removing the air filter or the air box and the plastic pipe behind the radiator, or I could remove it at the TB. Anybody have experience with this? Is it worth the chance of sucking up a pebble :rolleyes: Any times? Any tips?

i pulled my intake off at the track and ran 15.8s and 15.9s and when I put my cool air intake back on I ran constant 15.5s and then a 15.3. when you take the air box off you will suck up warm air right when you take off and your 60' will be hurt. all the hot air from your engine compartment is just waiting to be sucked into your intake. for track uses go to home depot and get that flimsy air ducting and route it from your intake(without the little screen) to the hole that leads to your front left fender. Or pay 26$ more and get a filter to put at the end of the ducting and now you have a custom CAI. at the track i reached my hand down to feel if my filter was warm or cold and it would have been cold enough to make go "ahh" if someone put it on my bare back. the flimsy stuff doesnt conduct heat and does really well. I bought a metal "scoop" and was going to put it on but I couldnt find a way to put it on without cutting my air dam.. sorry for rambling, some people say they have had better luck without anything but it hurt my times,

I just don't want ot suck up a rock or something. I should run the hose to the bottom of the air dam, right? Like drier hose?

You will be more likely to suck up something, and a rock coudl be potentionally dangerous like killing the motor.

Jsut run an open TB ot a hose that stays up pretty high...

We used to use pantyhose stretched over the Duct.

when you launch though your times(for some it is different) will be hurt well at least your 60' and that will hurt your 1/4. just get that ducting and a filter with a 4 to 3 inch reducer and make yourself a cheap cool air intake that is good for the track and road.

oops sorry, the reason your launch might be bad is because your engine, at least for the launch, will be sucking in hot engine air, get cold air from a better place and keep it away from the ground unless you have a filter. remember, colder air, more oxygen, better combustion, faster car, happier you.

The warm air thing is true but tell you the truth when I am at the track unless I am hotlapping and getting 2 runs in a rotation, so within, 20-30 minutes my car is dead cool and doesn't really heat up by the end of the track.(hence why I pull my belt with confidence)

As for the panty hose trick, it alwasy hurt me... I stretched them far but they still seemed worse then an air filter... Maybe I just had nice panty hose, with a fine mesh...

I pulled the air filter in mine once and lost MPH and a little ET.

Forgot to mention, I did notice a seat of the pants loss when I pulled the filter but after running the car for ~15-20 minutes(drive to track for me) Computer compensates and there is more power in the end and that is with the extra hot air from the engine bay...

Just with my tests and experience with my '00

Lat week when I ran my car with air filter in:
times were 16.08 @ 85.01 and 16.01 @ 86.91
then when I decided to take my air filter out:
times were 15.78 @ 87.12 and 15.84 @ 87.09
I actually gained in speed and times. I did leave the MAF screen in becasue of the fact that I was scared a foreign body would get into my engine.

Thanks ya'll, I think the easiest thing to do would be to just remove the entire air box but leave all the stock tubing. Then the air would be coming from right behind the headlight. I don't know if the ECM in my 93 is as hi-tech or sensitive as a 2000, but I think I'll let the car run in the staging lanes for 30-40 minutes before I run so the ECM can adjust. I remember I time I did this for about 5 minutes and the car drove great. I'll try it all different ways when I go Tuesday so we can have some solid numbers to work with instead of SOTP.

is pulling your belt safe to do? i'd be a little nervous about that. what precautions should you take when doing that?
