Procharger filter-less

[swflastang05]

I've been wanting to try running my F-1A without the cone filter in place, since the filter gets all messed up from all the suction collapsing it. I'm thinking running filter-less may result in a little more power, maybe. In any case I'm trying to decide if I should just remove the filter from the inlet pipe vs. removing the whole inlet assembly and just let the air come into the SC directly. Since it's a rear facing inlet centri, heat is an issue. Does anyone have experience with this? Is there real data from IAT differences etc.?

Here's a pic, if leaving the tube the concept would be getting cooler air from the cowl hood opening in the back.

Are you using a oiled filter or dry? My '07 was NA and I went from an oiled filter to a dry and it picked up a small amount of power. I don't remember how much no. If your only tracking the car now then you could get away with no filter. Have you thought of fabing a duct off the cow hood to match up with you intake tube when it's closed? you would get much better air that way. Just a thought.

It's an oiled filter, like a K&N. I still drive it on the street too, just early morning cruises on the weekend but it's street driven sometimes nonetheless. I have thought about fabing something like that, but not in much detail yet. I'm trying to visualize how I could do that without it looking stupid. I know I have high expectations, I want it to be fast and look good too lol

In that case I would go for the dry filter and fab a inner wire cone to hold it filter in shape. Looking good and going fast is a challenging problem sometimes. Maybe a lower shield, say .75-1.0" from the bottom of the filter if room exists attached to the filter in the shape of the filter. Maybe 1/3rd or so of the bottom of the filter. That would still look good and function.

There are mushroom filters that will fit right on the supercharger itself. I thought about the same thing when I had a D1. In the end I stuck with the Procharger setup.

A friend of mine was a racer with sponsors. He contacted Procharger about the Chinese copy of a Russian tractor looking air intake. They told him that they took the time to develop a different cai that got air from the ground. It resulted in 5 degrees less air intake temp in a S197. That was it. The Procharger air to air intercooler works pretty well considering the amount of boost it puts out. It negates the perceived hot air going into it by being located above the exhaust.

If you can come up with a better mousetrap then more power to you. IMO I always thought the filter wasn't big enough for the air entering the motor but I was able to make pretty good power with what was provided.

I've done a web search on the same thing and read the foam filters that come on the typical mushroom filter setup tend to break apart and when they do they can end up in the impeller. Screen filters are also less than ideal compared to a traditional filter because you take away from the surface area. JeremyH explained this in another thread. Traveler's idea of an inner wire cone is probably the best option.

BTW what are the dimensions of that filter in the pic? I need to replace my Spectre knock off.

I noticed in your pic that the abs control unit is gone. Did you relocate it ir remove it?

Here is what I made for mine.

Thanks for the replies, I'm not really worried about finding a different type of filter but rather if there's any power left on the table from running one at all, I'll just leave it as is for cruising on the street. Next time I go to the track I'm going to make a few passes with vs. without and see how it goes. I may mess around with the idea of some sort of cold air intake that connects to the cowl hood inlet in the back if I can make it look decent.

Yes I removed it last year, about 900 miles ago, haven't missed it at all.

Thanks for the pic, I knew you had something like that but wasn't too sure on the details. If I made something like that I'm pretty sure it would hit my BOV in the same area as the filter so I would need to tweak it a bit somehow. Do you feel that set up helps? I know your car makes a shit ton of power so it's not hurting anything that's for sure!

It does help on the top end and on the road pulls. Manuel has comented to me several times on the ait difference from the stock setup. FWIW, I have a BOV and wastegate in that same location.

mine is a coyote platform but filter placement is similar- I remove at the track and notice a solid .15-.2 tenths in et difference and 1+mph in trap speed- revs faster as well- tried multiple times with multiple tunes- on a d1 w 10.5ish psi. .You are a lil quicker than I am so I would assume you would see a tenth and maybe a mph. and another #of boost maybe.

 

[bujeezus]

I know you said you weren't interested in another type of filter but any reason not to try a dry one? I'm running an R2C dry filter and love it. http://www.r2cperformance.com/assets/1/Products/500x500/Mustang Bullitt Filter 020.jpg
Course I don't have a supercharger. Have you thought maybe you're oiling it too much? Just throwing out ideas.

Okay very good to know, thanks for the info. If Manuel says it's good than it's golden in my book, I know he forms his opinions on solid data and results, no BS there!

^^This is exactly what I was looking for! Thank you very much, can't wait to try it out! Do you remove the filter from the tube or the entire tube assembly and leave the inlet completely open to atmosphere?

Thanks for the suggestion, maybe I'll try one of those for the street next time I need a new filter.

entire tube so blower is open- often wonder if a blower velocity style stack would help direct air more smoothly in- I think there called bell mouths.

Don't remove the filter unless your car is only driven at the track. If you're concerned about the appearance, keep a shiny filter in the trunk and swap it out at car shows.

That's what some guys do with floor mats and stuff...

 

[jjjferro]

Is there a screen or something that can be attached to the blower for track use instead of just being wide open?

Yes I can make a screen out of 1/4" square wire. Manuel actually suggested that too, just to prevent it from sucking in a large item like a shop rag or something. I actually know a guy where that happened, he was working on his car with the SC filter off, then cranked it to test something and it sucked a rag in that was on the fender next to to SC, it screwed it up pretty bad, he had to send it back to Vortech for repair.

If you remove the filter is there a chance of it running a tad lean? I know the filter will restrict the air a little bit.

 

[Wes06]

if it pulls in more air, the MAF should read that air velocity has gone up slightly and adjust, but im just a keyboard tuner

I was just thinking out loud too. Hahahaha
