made cowl snorkel

[rangerrager]

hey guys just figured id show my new cowl snorkel.let me know what you think and how it will perform.
in the picuteres u can see the tube go into the cowl thorugh a sheetmaetal plate i made to replace the cover thats on there stock.and the pic of the front of the truck i threw in there cause its sexy

lokks like its workable to me.

 

[rangerrager]

awsome ..thanks..anyone else?

It doesn't look bad, but MY main concern with using a cowl snorkel would be rain water getting in to your air box. Let us know how it works out and let me know after a good rain if you had any problems.

 

[rangerrager]

yea i was concerned about it to..so was about to out a peice of sheetmetal in side and attach it to the grates from the inside so you didnt see it but it would prtoect against water,and it turns out there is already a little roof there stock.i stuck my hand in the cowl and was like oo wow..thats easy.so it should be protectd alrady and if not i will resort to my sheetmetal plan..u will never see it in there.especially if i paint it black

 

[Mechanickid]

looks good!

 

[kevinsranger]

you would never get enough rain to hydro loc your engine like that anyway, looks good, i made one but i went thru the inner fender well and into the side of the cowl, yours looks much easier

Once the metal gets heated from the engine compartment heat, you will have a HOT AIR INTAKE!!!!

Not good!!!!

The OEM CAI works just fine!

I think he classified it as a Snorkel, not a CAI.

Looks good man, is that dryer vent hose?

Either way, heating the incoming air is not good........

 

[BlackBII]

I agree totally, but, if your in a river, having water come in the airbox is not good either. That's why my snorkel goes out into the fender

 

[rangerrager]

yeah it is dryer vent hose..idk..is that bad that it gets hot..whats the worth that could happen?

It won't hurt anything, but from a performance, and efficiency standpoint, hot air is less dense than cold air, and you will get slightly less peformance, and MPG.

True, but off road fuel efficiency isn't a major concern. Actually makes me wonder. Did he set it up so that it could run the stock intake on the street and then flip a panel and run the snorkel offroad?

I'd be most concerned about "snowplowing" water over the top of the hood. Induction through the cowl may get drowned. It's not very hard to do that.

Though I'm not sure what I'd do about it.

Note that a completely different take on the whole thing is to build a SMALL redundant snorkel (like, 1 inch or smaller), and keep the stock intake. With two air paths, you can't suck water into the box; it has to get submerged. The auxillary vent can just be secured to the top of the firewall -- this is an emergency feature, not a performance feature, so you really don't care if it gets a bit warm. This would give you quite a lot of depth for very, very little cost in parts or performance.

Early 2.9Ls even come with the tube (though it's unsecured and often points down to the road, which disables it).

Bob, you're overstating the effect of warm air. It HELPS mileage slightly (very slightly for EFI) because the fuel evaporates better. It hurts peak power slightly. Many intake manifolds are heated either by coolant or by sucking air off the exhaust manifold for this reason.
