914World.com _ 914World Garage _ Group buy air deflector for cooling. Change airflow under the car

Posted by: Mikey914 Oct 9 2017, 07:32 PM

As mentioned we've been working on these for some time. Just getting to finishing these up.
They change the airflow to help cool the engine better.

$28 A set who's in?

Do these work better than the stock ones?

The stock one work ok, we have been playing with adding some small "wingtip" vortex generators. On the edges, it's a part that could be cut off for the concourse crowd, but would help improve the movement of air. I generally like to spring options right before the parts are ready, but yes there will be an improvement for those that want it. biggrin.gif

In for a set, one of mine is broke halfway through.

Geez, how can I resist a "wingtip vortex generator?" I'm in for a set.

Mark, I thought you just flew planes. I didn't think you knew anything about how they work smile.gif

Posted by: Mikey914 Oct 10 2017, 09:19 AM

One of the few aviation geeks that decided to build car parts instead of kit planes. However, I have made some parts for some friends experimental aircraft.
So not you too can fly low and fast across the ground biggrin.gif

Posted by: second wind Oct 10 2017, 01:10 PM

Pictures please and is there any quantifiable evidence of cooler temperatures? Just thinking out loud here....thank you.

Yeah what do these things do? 4 or 6 cylinder?

If you look under your car, attached to the bottom of the firewall (or, well, supposed to be) are two little air deflectors that hang down. They're supposed to be hanging down from the firewall.

The purpose of these are to - duh - deflect under-body air downward and create negative pressure behind them, under the cylinders. Due to this negative pressure the positive pressure at the top of the cylinders will cause air to flow faster/better downward through the cylinders and heads, improving cooling.

If you don't have these, you really should. It's actually surprising how effective they are.

Edit: found a photos online. It's that black deflector at the bottom of the photo:

They weren't on the 6 as it was before their time. So from a concurs standpoint no. They will "work" on all. The idea is that the air is flowing past the opening where the engine compartment is and has been directed parallel for at least the 5-6' prior. So these are mounted at he firewall to create a low pressure area on the engine side. The hot air is sucked down and airflow is disrupted. The "vortex generators"are technically a wing-let that allows for more low pressure to build (a more efficient "wing"), and works at a lower airspeed. Honestly, the improvement I have made may only make the part 2-3% more effective (as it does in aircraft). So mine will not be 20% cooler than stock but there is data so show it is an improvement (at least on the aircraft side). Also we can easily shave these off for the CW should you you be in that crowd (and yes I do lean that way, but not a card carrying member).

Hope this helps with the concept and thanks for posting the pics up!.
