To cold air induction or not to cold air induction ? That is the question . I'm asking this because my LT1 isn't a street car anymore and could my Moroso CAI kit be holding my car back a little ? I know some Stock Eliminator cars run with the Throttle Body wide open. No filter or nothing in front of it. I took my Moroso off and it seems to have much more throttle response . I wish the tracks were open now ,but I have to wait til March to find out if this will free up some hidden horsepower. Thanks in advance guys.

 

I think no filter is pretty dumb. Not only are you sucking in dirt in the air, you are creating a large amount of turbulence at the mouth of the throttle body. At the very worst, stick a filter on the end of the throttle body. That will keep out dirt and help straighten the airflow into the throttle body Your moroso filter should fit perfectly on the mouth of the throttle body.

Yeah I agree , but It's not that bad of an Idea. Now if I was running a CAI kit without a filter on street driven car.....now thats dumb. But a strip car ,it's only going to go from the trailer to the track and back on the trailer

Plus the throttle bodie is so high up ,theres no way any dirt is going to get in the motor like that. Now you may be right about the moroso filter fitting the TB, but the only concern would be the neck of the thermostat housing. I will try that out this evening.

 

You'll be surprised how easiely dirt gets up there. Remember that the under hood area is a low pressure zone. It's designed like this for aero stability and also to pull air in easier for the radiator. Anything that can make it's way past the fins of the radiator and get in the throttle body. Just imagine a large dust cloud coming in contact with the internals of the engine !

Then again, you will be pulling in hot air, not cold. The only thing you are changing about the induction is the fact that your removing the "neck" of the CAI system. I'm going to wager that you will see a reduced ET without the CAI.

You could be right ,Shannon. But if I do run a quicker ET, I want a 12-pack of ICEHOUSE and money for a Steak Dinner

 

How about a gift certificate to Bed Bath and Beyond

lol

lol .that is gay ,man.......funny...but gay ! .......lol

 

I would at least plumb in air from a cooler source than underhood. I have seen several stock eliminator cars run the factory RA set-up with no filter.

 

Thanks Perry, I'm going to try it both ways. I'll keep you all posted .

 

The CAI isn't restricting the intake side nearly enough to slow it down. I think you will see no difference, and its just an unnecessary risk to take. I personally would NEVER fire any of my vehicles without an airfilter. Dirt particles about the thickness of a human hair is enough to damage internals, and I have never seen a dragstrip to be the cleanest place on earth either...

 

CAI is the biggest waste of money I see everyday. Thats just my .02 cents though. If you are really worried about losing 1-4hp over a CAI your insane. To get the most out of your car just step up and purchase some real mods.

You can always buy some pvc from home depot and fab a CAI for 20-30 if need be. I have done that before and I couldnt tell any difference from a name brand CAI and a jimmy rigged one.

 

Honestly i wouldnt be worried about the CAI itself being a restriction, however the POS filter that comes with the moroso CAI is tiny and no way can breath what a big HP motor needs. I just bought a HUGE (12 inch long, 6 inch diameter, 4in inlet with the bottom inversely coned too) KN filter. Havent really figured out how im going to attach it to the moroso, but it will outflow the moroso filter by a ton. Likely just take the mounting plate, cut a hole in it and weld a 4inch pipe on angle to it. Shrug, havent messed with it yet.

Another thing i have seen is buying a set of pantyhose and using that as a psuedo filter. I guess its fine enough to keep out most the stuff that will really hurt the motor, but allows the motor to breathe still

 

i remember once seeing something like thta but it was made of a thin mesh screen, over the carb of a monster pro street car at the local strip. i dont know what it was really for caue i know it wouldnt stop dirt from gettin in there, must have been to keep large chunks of derbis and small animals out

 

id run the CAI, better safe that sorry

i know i wouldn't risk my engine for 5 horsepower

 

Its funny, I did that for one run down the track couple years ago. Just removed the whole box from the car, kept the pipe on. Didn't seem to make any difference. I think you really need to be making a good amount of horsepower for it really to be a restriction, which you seem to be Mac 93.
