Engine/Transmission (1998.5 - 2002) Value of "special" aircleaner ducting...

[Gary - K7GLD]

This is NOT intended as a "knock" of some of the aftermarket "cool air" induction setups some here are using, only the results of an informal test done on my own truck...



I recently installed a NAPA BHAF on my '02 truck, and in connection with another temperature related project, decided to also see as nearly as possible what the underhood temps were in the area around my BHAF as compared to ambient outside temperatures - here's my BHAF setup:



#ad






SOOOooo, with outside temps at an indicated 91 degrees, and after a 5 mile drive on reasonably level road at 55 MPH or so, my underhood temp over on the inside of the BHAF, next to the turbo, registered just under 100 degrees - an increase over ambient of about 10 degrees.



Now, I gotta wonder exactly WHAT real-world benefit is to be obtained by hacking holes in firewalls and installing fancy ductwork - all to (hopefully!) reduce intake air by another 10 degrees...



Nor is mine the first such test I have read about - and the others also indicate about a 10 degree underhood rise in temperature at common freeway speeds...



Just a FYI to ponder...

what kinda temps do the frantz create?

UMMmmm "create"?



None that I'm aware of - not really one of their claimed features as far as I know...

heh heh



if ya think that is cool, just wait!!!

 

[Bob Wagner]

what is the canister temp during operation, from a walmart point of view :-laf



cold as ice or hot as hell

 

[ThrottleJockey]

Uhhmm, Gary?



What Bob is saying is that due to the fact THAT THERE IS HOT OIL FLOWING through the Frantz...



... what kinda temps do the Frantz create?

 

[Gary - K7GLD]

On the few runs I've done so far, canister temp for the Frantz oil filter runs about 20 degrees below coolent temperature - which seems to be about 185 degrees - at least that's what my engine block registers after full warm-up and a 10 mile drive...

As posted above, and for sure, the Frantz has LOTS less heat and radiating surface than does the engine and radiator plus A/C condenser...



Pretty minimal affect on underhood temps...

The Frantz is dual purpose:



1. extra oil filtration

2. intake air heater

Cliff is gonna mount a Coleman 12v cooler onto the front of his grill with barbed wire (anti-theft). The most important part is the KX500 rear fender support that has been modified to lower his drag coeffecient!

HMMmmm - all that, and cold beer at the rest stops...

You have already discovered one on the many hidden attributes!

I should have the air box done today. The scoop is in "free clean" air, and if everything works as it is supposed to, I should see 1 to 2 psi of boost when idling and the truck is moving at over 60 MPH.

 

[Diesel Freak]

almost done.

Pretty slick looking set up there, D. F. You must have mover the battery tray back to where the air cleaner used to be.

Gary, I've always considered you relatively knowledgable on here, but surely you realize that the purpose of "hacking holes in the firewall" is to get more air into the engine to create more power, and not to solely reduce the temperature of the intake air by 10 degrees. In fact, I've never even heard that mentioned as a feature.



You act like you've stumbled upon some startling revelation here, when in fact you're missing the main point.
