Default Fe 427 turkey pan looks or functionality

What is the general consensus about turkey pans, looks or functionlity? I was under the impression that it would be the origins of todays cold air intakes. Any thoughts pro or con turkey pans.
Tks

I have one on my Backdraft Roadster and a K&N Filter that has exposed, oiled element on TOP as well as sides. It should work better than Smelling (s) that was OE on Shelby cars.
I like it.

95% looks; 5% percolation prevention.

Is percolation a scientific word for vapor lock? In Arkansas, we treat that with wooden clothes pins. It's a heat sink and fuel line locator solution from my teenage years.

Dang, I don't think I've even seen a wooden clothes pin in 40 years. But yes, the gas in the bowls boiling after you've stopped. I know when I'm driving I can literally see the heat coming out of the hood scoop.

Well, I am 59 years old, so our math checks out. We put ice on intake manifold between runs on drag strip (George Ray's Wildcat Drag Strip).

It was featured on Horsepower TV with Joe Elmore.
He "forgot" to mention outhouses vs restrooms back then.
George Ray was a great guy and provided lots of fun.

Thanks for making me smile!!

I added 3" alum dryer duct hose via in cabin fresh air vents that are pipped from the front air duct vents on each side of the main radiator opening. One from each side(via 45degree 3"tee) & piped them into the turkey pan. This plus a good foam seal from the pan to the hood & a full K&N 7"X2" round & top cover filter insures a strong flow of cooler air. With out allowing too much heat to affect possible fuel vaporation. Proir to this, I was not receiving enough cfm to properly feed my carb. & also had some probs with the heat! All is good now.

WELCOME TO THE ADDICTION THERE IS NO CURE
Silversmith:
tks for the idea. Yesterday during a run one of the Cobra owners questioned my turkey pan set up.
I have had some vapor lock in the past and it was mitigated by gas line relocation and insulation. Other schools of thought claim that Shelby had the original idea when he piped the air through the hoodscoop via the turkey pan.

While it is true that it gets hot and could overboil the gas in the carb bowls the idea has its merits. I have seen foam insulation around the turkey pan and better seal between the pan and hood ( the foam looks hideus, but supposed it works) .

I would hate to go through the motions of removing the turkey pan to obtain minimal advantage. I am considering a very expensive ram air system sold by Jegs but I am not convinced that I have the space availability in my engine bay.

With winter around the corner I need to set up the improvement projects the right way nd get the best advantage for the Snake.
(I know I will be roasted by this but...I can take the heat---no pun intended)

Cheers
Lou

Would something as simple as an insulator gasket or spacer under your carb help?

It would be simpler than alternatives being discussed. 40 years ago, the fuel lines got wrapped with foam insulation, sometimes relocated, and an electric fuel pump and 99% of the problems were solved.

Is the ram air a filter with two hoses going under the front end of car like the 1960's Olds 442?

You have my sympathy; it is a hard problem to isolate.

Russ:
I have installed a phenolic 1" spacer already, I relocated the fule lines and are wrapped already with insulating material. The fuel pump is mechanical pumping 9 psi cold and hot so the pump seems to be working fine. I have stayed away from the electric pump thinking that I might isolate the problem other than the pump.
The ram air system has the hoses from the front grill to the carb stacked high.
tks
Lou

Lou, I don't know anything about your setup, but, if that pump was on my FE, feeding my Holley 750, 9 PSI would send my needle and seat out the hood scoop and bouncing down the street. 5 to 7 PSI is the maximum for my Holley (and for most carbs that I can ever remember).

After I saw your posting I went back to the garage and got the car out and double checked the reading again it is 7 psi. I also found this site let me know what you think:
Ram Air Box.
My set up is nothing out of thr ordinary; a mecahnical pump to the online filter and the gas preassure gauge to the carb.

7 PSI is fine. I like the ram air box -- very cool looking.

Lou, unless you're racing Erica Enders next week looking for a 6.50, forget that crap. It'll look like a shop vac on a soft motor-or ANY motor...
Pulling cold air and isolating heat is simpler and very effective. Vent whistles in the bowls help avoid stalling too.
Just do this:

Naaaah, I like his post better. I liked the ram air look on my Olds 442 that I had back in the 70s, and I still like it today. You're just gratuitously mean.

Now I know how you got to two roll bars-you started with plastic (inner) fenders.

You know I don't know who to believe... I tried to get a serious answer and possible viable solutions and instead I feel I have been ridiculed. This is not the purpose of these forums!!

I like the ram air look, and I know I've seen it on other Cobras. Ignore Chas, he's not "all there," if you know what I mean.

Lou - Patrick pretty much answered your question here...

Mostly looks, but a small part is performance - like an old school air intake ie: separating hot air from cold new fresh air from the hood scoop similar to a cold air intake.

As for the old married couple bickering amongst themselves in the corner, don't mind them, just consider it side entertainment.


PS: as for what looks better... Personally I'm not a fan of Patrick's taste.
