Another way to get cool air into the engine compartment ! We all know that we are borderline on getting enough air in there. I spent a lot of time last year checking this out. I feel that a few of us just don't do enough testing to find out why. Anyway...this is a really cool way of correcting the problem in a beautiful way. VERY stylized ! The vacuum closure (I think) was cool too ! I wish I could do body work like that !!........Bruce

Did you see the two sequels??

I look but do not see how air gets to the barrels.  I think I understand how the oil gets cool, but not the  engine proper.  Pls explain.  The body work is immaculate, the no-handles opening is the bomb -- howdeydodat?  and the seats look more comfy than a barcalounger.  And yes, very stylized, maybe a bit much, but so good looking nevertheless.  Very cool.  Lighted nerf bars??!!  Holy carp . . .

He/They have done a lot of neat stuff, but it's all just to be different. It's all very well done, but I'm not sure how well it's all been thought out. For example, as far as I can tell, air is force fed at speed into the engine sheet metal for cooling; but what about when it's idling at a light in traffic? And I'm sorry, it's a show car doesn't cut it; putting so much into a Speedster (steel or fiberglass) that you're afraid to drive it is sacrilege.

The electric door solenoid poppers are actuated by a magnet mech. in the door , the triggering opposing magnet is a key fob, they will soon offer a finger ring that will do the same thing.

It looked like it was his ring that operated the popper. He puts his left hand with his ring along the door and moved until it opened.

I applaud the guy for thinking outside the box, but he's running an air cooled engine with no shroud?  Also, that fan mounted under the big oil cooling would pull a lot of hot air into the engine compartment directly into the carbs, which don't have air cleaners.

Maybe he has a type 4 engine with type 4 cooling and the pop-up scoops direct air directly to the carbs.

I can't get those videos to play, but Henry uses a cutout behind the rear licence plate on his six cylinder cars, and that brings additional air into the engine bay.  But maybe that's only good for a flat six engine - I'm not sure.

For someone who's trying to get more air to a VW engine I'm sure it would help as well, Bob, although with positive pressure pushing air in from the front firewall (from a 6 or 7" hole, or "gap" as Alan does) I wonder if the airflow through the engine compartment (and removing heat from the exterior surfaces of the engine, components, shroud and cylinder covers) and then exiting through said cutout is providing more cooling? 

Stan has said that a firewall hole didn't seem to do that much for temps in his car- I wonder if this would be his answer?

Is the 7' hole only functional with the stock fan housing? I have that hole blocked off because I run the 911 fan shroud (no cooling issues).

I've always thought some scoops to fit the carbs would be beneficial on the open highway or drag racing but don't want to have a couple of warts on my car. These pop up scoops are cool but I question how well they work on that set up.

Is that a type 3 motor?

I think the firewall hole would still be beneficial with the 911 style fan housing, Bill, as the positive pressure would feed the carbs, and (if it didn't upset the airflow) add to the fan volume if it needed it.

It looks like a Type 3 Motor;

Forgot to mention, I have an oil cooler mounted to my firewall.

You need to move that....
