Bhaf For Mpg

Yes so far so good. We've had some real crappy weather here the last 2 days. I took it off today just to look, and the shield stopped a ton of salt from coming at the filter from the shock tower area. Very good fit.

AGPTurbo, I bought my Fleet Guard BHAF off of Amazon for $45.00!!

There is something not correct with his data, it's doesn't make any logical sense.

 

Nearly all of the air going into the engine bay crosses the intercooler, a/c condenser and radiator, it's then heated by the 200° block, 1000°+ exhaust manifold, and 400°+ charge air pipe. A BHAF pulls nearly all of it's air from that same engine bay, a small amount comes from the hole in the fender.

 

How are you only going to see a +20° rise? It's not going to happen, that's how.

 

With my sealed box, pulling air from only outside the engine bay I see a 15° rise over ambient 4" after the filter when pulling a grade. With a temp probe on the outside of the box it is 125° over ambient, and that is believable 20° is not.

 

 

 

We went over this before.  I have nothing up front, no batteries, no overflow or washer tanks.  I have nothing.  The air free flows through.  Sitting at a stoplight it would skyrocket.

That's right, and that will also effect your moving temps. It's also why your data is not relevant for a truck with all their underhood stuff.

You start driving that thing again?

Then say that before saying I don't make any logical sense.  

 

No I haven't even started it in a year.  I'm just gonna sell it, I have no use for it.

I honestly just forgot you had gutted the underhood, which in retrospect makes perfect sense. So, for a truck like Michael's the results would be different and probably closer to what I have seen.

I'm trying to get my hands on a spare thermometer for this purpose. I don't think I'll see you level of temps ever either. IAT always follow the +40*F rule. I can tell the outside temp by just looking at the IAT which is always close to +40*F rule. The only time this doesn't apply is when the engine is cold then the IAT matches outside temp.

[AH64ID]

My IATs vary based on ambient and load, but empty they are generally +6, but as we have said the sender location has a lot to do with it.

With an intercooler and the location of your MAP sensor I am not sure you would see it on the IAT, the +40 without a load shows how much the coolant effects the reading and probably why they moved it on 3rd gen trucks.

I cannot think of anything that would change the temp, and I wouldn't be shocked if it was higher simply because there is more downpipe and the turbine is much higher and further forward on a 2nd gen vs 3rd gen.

Like I mentioned before nearly all of the air entering the bay goes over a hot radiator, intercooler, condenser and then is heated by the block, charge air pipe, and exhaust.

I've never seen the template for the heat shield.

Joe , it's in the articles section, 24v. Also someone just put the link in an earlier post
