Default filter or no filter

I have a question perhaps it is stupid one and maybe it isnt.
First off my car is race only and is never street driven.I have a K&N CAI and I was thinking of running it with no filter but I got to thinking that it may not actually get more air due to turbulance or not getting the full sucking factor that a cai gets.I might just get a new filter the RF1015 that is on there is quite old(8 years)
the car is running kinda fat right now also so the more air the better.I guess the stock maf could be maxing out also.I figure with the drivetrain loss I am getting the motor is making about 590 fwhp

any opinions are welcome

thanks

If your track has a lot of dirt and the pits arent paved I would run a filter, but you dont have too.

But I dont see why you wouldnt run a $20 filter to protect a $15k engine?

If you cherish your motor, then keep the filter on.

If you do not, then gain a few more cfm and trash the filter.

In testing a few years ago my Stocker was a tenth slower with the factory Ram Air stuff installed.

I was try to maybe make a high flow 'filter' of sorts. Maybe with say nylons over some sort of cage that mounts to the end of the CAI.

But like Speed said, if it's a dirtier track, make sure to run a filter, no use risking it.

I dont recall what mfg it was but they had a dyno chat that the engine would make more h/p with the filter thank just the intake, That was with a carb when I saw it though. I wouldnt risk it. You may want to run a cover or something on the tube though like others said

what I was doing was when I ran the motor in the pits I would disconnect the cai at the maf and just put that one clamp on in the staging lanes to hook it back up.I bought a new filter and I will give that a shot.I think my problem is that I am maxing out the maf anyway
thanks for the help guys

First off make a couple passes back to back with and without the filter when the car is 100% operating temp and see if you gain any MPH. If not then it is not even worth it. With my heads and cam I did not pick up anything when I removed my air filter. This was on my WS6 with the factory intake setup and an Accel air filter... kind of like k&n

Combined with your third O2 idea you must be busy. Are you on drugs or just naturally stupid?

When will you find the time?

Heck clean the basement mow the yard get ready for move to TN with mommy, sell the turd mobile. Now develop new air filter and of course the third O2 project. How can you do all that and make soo many useless posts each day?

You said you didn't want to start ****? Don't worry you are complete!

Wow, only five posts and every one of them offensive. Maybe you should stay off of here until you have something constructive to say.

If that coment is directed at me I can tell you for a fact that my car is faster without the factory stuff in front of the throttle body. My application is race only. In the class that I run (Stock Eliminator) we have two choices. Run the stock stuff or nothing! So I can't say that something from the aftermarket isn't better. Maybe someone can post up their personnal results on that.

heh Looks like Battle resurrected Bolter's name. Same exactly lame insult style as Battle. $10 says an IP comparison links them.

I think Phire was more implying me. I had a bit of a nasty reply to him but decided against it. I don't want to stoop to Battle/Bolter's level.

Come on formula I wasn't trying to get you fired up, I just don't wanna see STREET driven Lt1's demise from debris consumption, in pursuit of gaining 2 horsepower. You guys don't relize that inexperienced members read these posts and listen to our ideas, good and bad, If they read that someone put sugar in their gas tank and gained 50 rwhp, they might try it, and ruin their car.

Gizmo, Dave J, I didn't understand that your cars were stock equipped race driven vehicles, in that case I see no reason why removing the filter on a well kept track would hurt. However where air particles could be a factor, you risk causing damage to your maf, if your lucky, and severe irreputable damage to the motor if you are not.

I meant no offense to you guys, in the good old days, my father, and uncles all raced their 60's and 70's machines filterless, it's just that these days the computer controlled cars are far more effected by influences of air, temp, moister, etc. good luck, hope i've eased the tension,

The first thing to go on my Formula was the factory computer, etc. If you are going to race an LT1 an aftermarket computer is one of the best upgrades that you can do. I run my FAST in Alpha-N, so there is not much that it looks at in regards to sensors. Instead I change the tune to make up for changes in DA.
I always cover my throttle body while the car is parked in the pits. I also shut off the motor and coast into my pit space to at least lessen the amount of junk that the motor sucks in. Worse is tearing the motor down for the IHRA tech to inspect it. Especially on a windy day.

Take Care,

Daren
