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?

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

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

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!.

Posted by: bbrock Oct 29 2017, 10:04 AM

Just checking where this group buy stands. Three are a few other GB items I'm getting ready to order and wondering if this can be bundled in to save on shipping.

Posted by: Mikey914 Oct 29 2017, 10:35 AM

These will be in the next wave. I currently have 6 GBs open including the master cylinder, and I found my site can only take 5 codes at a time. I have a few other new items and will be grouping my GBs to save all money. The only catch is that when this group is closed, it's closed. I can't carry them over indefinitely, otherwise why do a GB?

I just need to finish some machining, but also working on the master cylinder assembly and testing so it may be 10 days or so.

No problem. Just wanted to double check before placing my order for master cylinder and drop link bushings. Will get them ordered today.

If a car was an early 70-72 than there are no holes in the body to install them. Some measurements or a template for installation would be very helpful.

For a template you really only need to know where the 1st hole is for the side. The rest you can use the part to mark the holes.


I'm very happy with the fit on these the tool is a little rough so we need to do some more polishing.

Will probably take about a week as it's tool steel, and we can start some production aktion035.gif aktion035.gif aktion035.gif

I need a box on the shelf out there. Just keep putting parts in the box until it fills up, tape over the top and ship.

If these get done about the same time as the suspension bushings are ready to ship, may as well add two pair to the bill.

Posted by: bbrock Dec 8 2017, 11:39 AM

Posted by: cary Dec 8 2017, 10:58 PM

Here's your starting point. Based on the 3 cars I looked at here at MiddleMotors the first bolt is 15mm from the jack point plate. But beware ................
Most cars have seen some sort of rust repairs so use the 15mm as a starting point. But make sure you can drill the holes and get your 8mm socket or nut driver on the other two 5mm bolts.

Here's the pilots modification the bottom edge.

I think Phil Knight has something like that on his G650.

I put them back on Doug's car for photos but forgot a couple shots. mad.gif Tomorrow

The Haynes manual has specific instructions (& measurements) on how/where to install these on early cars. I'll try to post pics later.

Ok - here are the pics (from page 194 and 197 of the Haynes manual). Not much there, but hope it helps. I recall having to dig some seam sealer off the weld seam to drill the holes, but it's pretty easy job:
