What CFM did you calculate?  Assumming the Busa is at 1300 cc w/ a 1.6 VE at 6K RPM I come up with 220 CFM.  That would put you into a 3" unit that has the same dimensions as mine.  They offer the 4" that is 10" in dia. and about 18" long that would surley handel the Busa. Keep in mind you want to size it close so the turbine spins fast enough to spit the dirt out.

Not bad for a good filter/prefilter that does a good job of keeping clean air available. I was looking at their sizing chart and it appears it needs to be HUGE for a turbo busa. Am I missing something? I guess I COULD call them huh? Well,there's another thing i need to get done. drowning

The busa turns 12,500 rpm though. You do the sizing according to max rpm don't you? The 10x18 wouldn't be so bad but any more than that it becomes a packaging issue.

Oops! Yes you would size it for max RPM.   That would put you in to the 5" series and it would be 32" long.  Are you actully running the motor at its peak? I would call the supplier and talk with them. The max of 10 "WC shown on the chart equates to only a .3609 PSI pressure drop thru the filter. Thats not much. You could probably use the 4" and still be ok.  The velocity would be higher however still acceptable and not impede performance. You would need to know what the max turbine RPM is however.

No, I would not be running iut at its' peak unless on long fast runs but that's not the point. I agree I should call them directly. Just got to get time.

You lost me there.

The VLR air cleaner has a Turbine  (fan) built into it to expel the dirt before it hits the filter.  I assumme it has a critical RPM before it goes Kaboom.  The motor vaccumme spins it, so if your outside its range then it could be a problem.  That would be a question for the Manufacture.

That turbine does not turn. It is stationary.It makes the air swirl to form a vortex that expels the debris before it gets to the element. At least that's how all have been that I've seen on heavy equipment.

Yes it has an actual mechanical turbine that spins.  Your probably thinking of the McDonnel series that does not have one.

The required Trans output shaft bearing is discontinued and had to find a replacement for it. I was able get a wider one that required machining .118" of the flange it rides against. The recieved the replacement 17mm wider bearing and installed it. As it turns out there was just enough clearence to install the shifter paw with the bearing in.  I trimmed .118" off the shaft to accomadate the wider bearing and all looks good to go. Well with the exception of I am not pleased with the excessive play in the new bearing.  My experience with ball bearings is they tend to have a zero to a slight side play in the inner race, however this one allows me to rock the shaft about an 1/8". I also discovered the main shaft seals are discontinued and had to find replacements for them too.

Thanks, It certainly did not come without its trials and tribulations :-[ :o lol.   After working thru all the bearing issues on the trans I get it Installed and discovered that my Driven clutch would not clear the frame and trans primary shaft. Even with all the pre measuring to determine were to split the 2 piece shaft I was 3/8" to long for clearence. So my solution was to remove 3/8" off the clutch wear it slides onto the shaft.   I made a split arbor so I could chuck up the driven clutch in the lathe and removed 3/8".  I then made an additional spacer to make up for the 3/8" I removed as shown near the trans. Allways something!
