New high Flow Airbox

[Jetpilot]

OK here is a question... How much would you TDR members be willing to spend to get a high quality airbox that would use a filter like the AFE Mega-Cannon? The box would supply plenty of fresh air (no not just the fender well opening).



The reason I am asking is to decide where to go with a design I have. If there is enough interest that I could supply these I might give it a whirl.



PS: Moderators if I am not allowed to ask this type question please let me know.

High Flow airbox

Jetpilot, Iwould be interested and I have a couple of buddies also. From you gotta friend state, close to the lake

 

[Mark_Kendrick]

I would too. . I'm about to design one myself.



I was thinking twin conicals

 

[yogibear]

Twin Conicals heh. . Mark you've been looking at Playboy too much!!

 

[Mark_Kendrick]

I didn't know madonna was in playboy this month????

 

[CumminsAholic]

Is this the design that was in a previous TRD issue? If so I think it's a good idea and I'd be interested in one if my tires will clear. Price... I dunno, I guess it depends on what it's made of and what it is.

This is not the one that was in the TDR magazine... . In fact it really doesn't exist yet. I want an airbox for my truck that will feed it plenty of air. I believe I have an idea that will work and just want to see how many others would be actually interested. I want to use the AFE Mega-Cannon style filter. I have no idea what they would cost to produce, but I personally would like to use something like high temp ABS plastic (similiar to OEM airbox material). Again this is just in the idea stage, there are alot of good setups out there that I think work for most guys. The only people that probably would benefit from this would be high HP guys who want max airflow and lower egt's.

Doug, you have my interest. While I am very happy with my Scotty air and K+N, I've been thinking about trying the AFE. Please keep me in the loop.

I am interested. The $70. 00 to $100. 00 range would make me more interested. It would have to work well for off-road (water,dust ,mud).

 

[Mark_Kendrick]

I think the ABS would be the nicest. . Low heat absorbtion etc. .

ABS is expensive on the startup. I think a metal box would be easier to build and prototype. . if there was demand you could then make it in ABS.



Metal is easy to modify also.

 

[Jetpilot]

Mark,



You are correct about ABS vs. Aluminum or SS, it would be much easier and cheaper. But the ABS would be the nicest for all the reasons you mentioned. I don't even know if this airbox will come to be... . I am just trying to see what the interest is.

[yogibear]

Jetpilot, I would also be interested.

I think understanding the gols would help...



I'm looking for 800+ cfm at 6" of water.

a readily available filter.

Ability to have more than one air source. (places to get air from 3-4 sides )



If it mounted near the passenger rear side of the engine compartment you could get air from the fender, the cowl, above(hood scoop or the like), or front. So flat surfaces on 3-4 sides large enough for at least a 4" flange to be attached . . 6" would be nice

 

[RustyJC]

I'd be interested, especially if it isn't drawing air from the cowl. Not all of us enjoy listening to turbo whine for days on end while on an RVing trip.

Doug not to shoot holes in your plan, but i would just like to add a few pointers.



the High HP crowd is a limited market and harder to please.



800CFM is not a lot of air, but 6" of water is a big restriction. You should shoot for at LEAST half that, at 800CFM



you will also find that most of the egt problems are from the guys driving outside of their compressor’s map. not restricted airways.



take for example Kurt’s new B1 he is turning in better egts loaded, than some people have empty. that is not due to insufficient air flow at the intake. It has to do with the Pressure Ratio and efficiency of the turbine. Comparatively to the air charge density. The density is effected very little by the ambient temperature, but a lot by the compressor efficiency. Obviously ambient is important but not the root of all evil. The C/E is. also remember a turbo is a vacuum pump and designed to draw air in.



Currently there are four major movers selling aftermarket boxes for our trucks. Of the four, two of them are really good. The price will come down on them as the new wears off, and the dealers of them start getting antsy for revenue.



I can prove to you that a stock air box and filter Is only giving up 4HP on a dyno with a 450HP engine. And at highway speeds will only net you about 50F higher EGT’S.



We are not talking about highway speeds with 10K of trailer, just the empty truck like most of the high HP guys drive.



Good luck, just make sure you have a market. BTW: it is the $100-$150 range, and it better out flow the competition. Lets just say 800-900CFM @ 1. 5” H2O

 

[Todd T]

I forgot to add.



you may think the stock box is a contributor to Lag also. that is a huge misconception.



an HX 40 takes about 2 seconds to go across its map. add to that about 12" H2O to get there.



your ears are telling you it spools faster because you hear it at lower boost levels, with an aftermarket filter compared to a stock box. but have you put a stopwatch to it?



and no seat of the pants Ted Jannetty tests here either. use a speed gun and measure the acceleration of the turbine wheel over the P/R range.

 

[Mark_Kendrick]

Todd,

Not to ruffle your feathers, but...



I think you're off on the numbers, 6" of water is not much. the BHAF is rated at ~930 cfm at 6" and there is a noticable difference in spool-up and throttle response over a stock airbox.



Significant enough that I will not put the stock box back in.



Less than 6" would be better but I consider the specs of the AH19037 sufficent for high hp application.



I want BHAF performance in a ducted box. I have a 4xxhp truck and I want to filter like/betther than a BHAF in both flow and filtration.

 

[HEMI®Dart]

Put me in for one. I'm running the AFE Mega-Cannon/ Funnel Ram now. I have had every airfilter in-between. Still looking for a good design that only pulls cold outside air into the motor.

How bout' a cannister

Someone posted a while back about the ABS (? black plastic) cylinder cannister from Fleetgaurd for one of their filters. Had a picture and a part number too. Can't remember if it was for the bhaf we run but it was round and was just a housing for the filter to slide into. The only problem was it didn't have any place for intake air so I never heard anymore about it.



My idea is just to modify one of these and find a place for some outside air to get to it; either from the stock location, or maybe from underneath in the fender well area.

 

[Cummins Corvette]

If you make a GOOD box for the bhaf, that gets air from the fender opening and the scotty then put me down for one. I am buying one of the new ss malory mounts, but will always be willing to upgade for lower egt. An ideal setup would be one that just seals against the hood, fender, and firewall. That will be challenging with all the wires, ac lines and such. I plan on doing what I can to make this mount do that. There is also a gap between the fender and the firewall that would bring in more outside air if a sealing box was made. Let's do it! Oo. Oo.
