New Intake Horn Idea

[Greenleaf]

Guys, idea here.

Would it benefit me to remove my grid heaters and intake horn... . then install a unit from an industrial application w/out the grid heat? These other horns are much bigger,have the same bolt pattern from what I can tell and have no grid heaters. Increased air flow due to less restriction at the horn's 90° bend is my idea.



I don'r drive this rig much at all in the cold and never during the winter so the grid heat being in-op will not be an issue. Besides, all my 12 valve bus engines do not have grid heaters and they are used all through the winter.



Whadda you think? Do it or have my horn polished and keep the grids

I can't see how it would hurt, if the buses run ok without the grid heaters, then go for it I am assuming you would polish up the larger manifold too. If you don't mind living with a little rough running while warming up the few times it gets cold for you you shoudl be ok..... How many people run around with broken heaters, relays, glow plugs, etc (think fords and chevys... . )??????



Might want to check the battery condition though when it is cold



Keep the stock stuff and throw it back on if you sell the truck, or sell it to a fellow TDR guy who needs it.



Try it and tell us how it goes.

remove the heaters

They are for environmental concerns anyway. The few seconds of time that the engine makes a bit of white smoke won't make much difference. Keep them though. When the engine gets a lot of hours/miles on it (like close to a million) they will help. The engine has a distinctly bad smell when it is about worn out and the heaters will counteract that to some extent. The restriction posed by the heaters will not amount to much on a stock setup but as you strive for more HP they will need to be gone.

I had wondered about the intake heaters too. I have a 2nd Gen intake horn and all the piping, boots, and eblow just waiting for a 2nd Gen intercooler to mate up with under the hood. Here in the swamp, we didnt really have winter this past year, though it did make some whitish bluish smoke at less than 30deg until it got warmed up. Go for it. Worst that can hapen is it wont make any difference, but then you can say you have an aftermarket intake.

DP, those 2nd gen intake horns have the same bolt pattern too? Boy I really need to have a buddy with a 2nd gen 12V so I can look under the hood to see what parts can interchange

Jeez bro, why don't ya stick a hoodscoop outta tha hood to force the air in also I've kinda had that idea and have been waiting to see something like that here and have been kinda surprised that there's no talk of it...

Bill, yep they have the same bolt pattern. I even lined it all up, and the injector lines wont even get in the way of anything. Just have to check the length of the pipe coming in from the IC- the intake horn sits farther back on a nonIC 1st Gen than on a 2nd Gen, so I may have to add a couple inches. I think, coupled with the bigger cooler, the 2nd Gen setup will flow more air, with less restriction, and cool it a goodly deal more, allowing more power on diesel only. I might break 200 then.

Remove the grids... they are only needed in really cold weather.

I only use mine when the temps get below about 25 F or so...

It makes sense that they are impeding airflow.

I may remove miine when I build the custom intake horn...

ooops!

Thanks,

Just the encouragement I needed. I will have to fab a new intake pipe as the original will not work.



Looks like funOo.
