Electric Yenko style hood flap
Posted by: LeadFootLogan ()
Date: July 10, 2018 11:11AM

I am currently building a 65 Corsa 140, and I will be using it for autocross and street use. I live in Texas, so overheating will be an issue and I need a way to combat this. I came up with an idea of taking the yenko stinger hood flap, and making it able to rise and lower by a flip of a switch. This idea is a work in progress. The reasoning behind why I am thinking of this is because of rain,sand, dirt etc. So at times where it’s nice outside, then it’s pouring down raining, you can just flip a switch and close the flap protecting your engine and makes it where you won’t get wet from the rain. I do have a design(not a very good drawer)for it. Unfortunately I don’t have a computer next to me at the moment so I won’t be able to show the drawing right now.

Ben Carey did this with electric servos. His videos might still be on Facebook.

I think it is a neat idea. I don't think it is needed for a street-driven car, but still sounds like a cool project.

Guy in my club did something that is more effective than those dinky little flaps. His whole decklid is on servos where the hinges are and that end of the lid lifts about an inch at whatever speed he programs the controller. Pretty slick, I wish I had pics. But like David says, you should not have problems with overheating doing autocross or street driving in the Texas sun if everything is right with your motor and cooling system.

Why are you overheating? Are you removing all shrouds? All things in proper working order and that car will be fine in TX. Cool idea and yes Ben Carey did that. I think the problem with the flaps is they let water in even closed. Not ideal for a street car.

My corvair dosent run yet. I am currently building it with my dad, and I wanted to make mine unique. The engine will be modified so by adding more power=more heat. Also, knowing my 16 year old self will be driving it to the rev limiter almost everywhere I go. So, I though the hood flaps would be a cool addition to my Corvair and be functional as well.

Has anyone ever tried opening the flaps using the vacuum created by the engine when accelerating?

Vacuum is 0 in a normally aspirated engine under WOT.

If I were to do anything like that it would to add three small doors to the bottom of each lower shroud that would open with a servo when temps get to high.
