Hmmmmm I like that alot, but I wonder if its going to cause airflow problems while crawling. My brain says that it is, but my brain can't actually come up with a decent answer to why it will cause problems.

Well carry on then, if I come up with a reason for my thoughtless wanderings I will let you know:D

One other thing, do you think the windshield wipers will block the view of the gauges?

the wiper is a smidge in the way.. if your slitting kinda slumped, it blocks about the lower 1/3 of the gauges... if ya sit up normal, it's at the very bottom of the gauge... obviously thats not how they be final fitted... I'm gonna do a small hole black mesh screen in the whole back opening.. with the 3 guages mounted thru it with angle rings... I woulda liked another 1/2" of room, but I'll make it work...

I can't imagine any situation where airflow would be worse... I venture to guess sitting in traffic it would be getting more/better air than the tube to the rad suport any day... I mean, it's not like a rad with no airflow thru it..

I'm pretty certain the setup could EASILY feed a big cube BB in any situation.....

I'm also considering, when it's all done, adding some like 1/2" thick, foil backed, self-stick, thermal insulation to the underside of the pan... but again, I don't really think it'll "need" it...
 
I like the filter setup looks really cool man! But what are you gonna do if it starts raining? Wont that just allow for water to gather in their and get those gauges all wet? Or does that not matter.
 
well, water shouldn't gather in there... the cowl does overhang in the back.. I'm not concerned about the gauges getting wet, I ran the old fp gauge out on the hood for years...

i'd be more concerned with moisture being sucked into the airbox.. thus why I'm running oiled filters and a pre-filter... the pan will also have small drain holes in the very back corners...


here's a couple other angles to show the back...

oh, please.. are you guys serious?

you think that a stock tube/tophat setup or one of these pvc 1/2 a$$ snorkels people run even comes close to flowing what that opening will?

gimme a break, not a chance...

I have to agree, the size of the opening you have and the "air cavity" that will be around the actual overkill sized filter should be more then enough :waytogo:.
As far as the gauges go, I ran a FP and a nitrous pressure on the cowl of a 5.0 I used to own and with the exception of the cheap chrome rings pitting I had no problems at all.

Paul keep up the insane work, and keep thinking out of the box, I have gotten so many great ideas from your build and learned a lot of neat tricks different ways of doing things , So Thanks :bow:

I gotta agree with you too. My '70 1/2 Trans Am had the blocker plate out of the shaker scoop. There was plenty of air to feed a little over 700hp there. Water never seemed to be a problem either. Not that it was mudded or anything, but it was driven in quite a few pretty wicked thunder storms down south. I think a little water vapor helps things stay cool and dense for more HP.

You're making me miss my Blazer alot. Keep up the awesome work!!!

I actually totally agree Paul but for some reason I keep on thinking it won't flow enough air, but every time I think about it logically there is no reason it won't flow enough air to provide more than enough for a substantially larger motor.

Just different than what I am used too I suppose, different is sometimes hard to wrap your head around it.

Just seemed like a small area to suck air in while you are sitting on a trail where speeds are very low. But that statement makes no sense when you (as you referenced) think about the stock snorkel on the newer ( still our body style) trucks.

Carry on sir, these are the pointless ramblings of a thoughtless mind:D
 
The smiley face at the end of my statement was meant to say that they are not going to block the air, just another reason to put them inside.

I just like all my gauges in the same general area so that you not looking all over the place to try and read them. Back in the day the fuel pressure had to go out there which was ok.
 
with those gauges outside, wouldn't they fog up?

thats a good question.... apparently they can't fog up when they are liquid filled's... :rolleyes: I ran my liquid-filled fuel pressure out there for a few yrs, actually on the hood, totally exposed and had no ill-effects..... non-liquid filled? yeah, i suppose that could definitely be an issue...


that being said.... I can now report, I personally have seen a liquid filled fail... :(

I went outside and pulled the fp off the steel hood yesterday.. and all the oil had leaked out at some point in the last 3 yrs that it's been sitting on the side of the house...

now, it has been getting banged around a bit.. but... it did fail...


so... I now need to buy all 3 gauges for out there... this is where my stubborn, "I love the look of the Pro Comp 2 5/8's" thinking is biting me in the arse... here's why....

Id actually like to downsize them to 2 1/16" so they fit a bit better.. but as some may know, pro comps are only 2 5/8... i'd have to switch those to sport comp's to go smaller... and obviously the styling is a bit different..


oh, and my dash is full.. there really is no interior spot for em... I actually found it to be pretty effective visually having the fuel pressure out on the hood... plus, it looks badarse imo...
 
oh, just wanted to touch on something Eric said...

Just different than what I am used too I suppose, different is sometimes hard to wrap your head around it.
I don't think you realized how poignant that line is concerning my rig... a lot of the "outside the box" ideas and designs I do, I feel are often looked at like that... they somehow offend peoples thoughts of sensible or something... my glovebox breaker panel was like that.... most give ya the :confused: but every once in a while an old hotrodder would come up and say "that's sick".... they understood....

personally... I actually look at this mod as a HIGHLY effective solution on these rigs... it's gonna be about as effective as it can be performance-wise.. highly enhanced salad bowl effect... huge filter, cowl pressure under speed, cool fresh air...

but an equally important thing I think is water crossing... now obviously it's not as effective as a snorkel at the roofline, but I think with the fans off, I'll be able to get thru some pretty deep stuff... I go from having water be an issue when it's 1/2 way up my grill to another foot higher and drawing from an area not likely to have water coming in... if it's coming over my hood, I got other issues..

gotta go look around at mesh screen now... don't want birds, snakes and critters snuggling up to my air filter like a new woobie... ;)

Don't give up on the larger gauges....just modify the cowl (original one) to drop the height in that area by maybe 1/2". If the very bottom of the gauge isn't visible it won't matter, the important stuff is what's going on across the upper part of each gauge.

Personally, I'd like to see you figure out a solution that keeps those gauges out there.

:usaflag:

I bounced around the idea of modding the very back of the hood.. obviously anything I want to do with glass, I can... I really don't wanna mess with the metal cowl if i can... they're low enough as it is.. tho it's feasable, and wouldn't mess with the hood line, which i really don't wanna do.. It would just look/be a bit easier with a tad more room.. get a little more angle going...

toyed with moving them to center, and doing 3 little raised humps at the very back edge of the hood... I could also raise the entire back lip a bit... but I really like the hoodlines as they are.. I'll have a couple weeks before I get to the hood underside work, gotta finish the pan first, so I've got some time to tink about it... :D
