Yeah, compounded by being behind that C at the bottom edge of both sides of the mouth. I wanted to avoid cutting the bumper right now, I taped off the gaps up top by the radiator to increase pressure up there with the idea being the radiator should block more air = more pressure to push through the brake ducts. I read up a lot on custom intakes where they mentioned using the above to smooth out the transition of the flow. I think you might actually have something here, if I can get my hands on some testing gear I can make one out of modeling clay and do a few laps to see how temps look compared to the unmodified side.

I wonder if those FLIR adapters for your phone are worth any weight?

Got my hands on a set of the GV front bumper extensions, they should block all flow over the tires and from what I gather they do wonders for front downforce and stabilize the car quite a bit - very noticeable over 100mph. I'll do some coasting sessions to see how she rolls before/after to gauge drag. I'd like to see better fuel economy so I have more gas for driving and use less for driving

Front white part here:


Oh, and the back part above is very similar to what HotRod mag saw w/ their 80 Camaro (see Here) which didn't reduce drag but gave -40 pounds of lift in the rear verified in the (mentioned before) A2 wind tunnel. I suspect even without sideskirts (just like the Camaro) it will also increase -lift and probably not do much for drag since the tires are already out roughly as far as the rear deflectors. Pretty impressive in my opinion.

Car Aerodynamics - A2 Wind Tunnel - Wind Camp Tech Theory
Here, Eaker is examining the stock Z28-type side spats, which did not alter the Cd but added 40 pounds of rear downforce. He thought they may be more helpful in yaw but says testing 0 degrees to the airflow gives you 75 percent of the data you'd need at slight yaw. We also tested the Moon discs, which reduced drag by two to four counts. The farther the wheels are from the outer edge of the fender, the less the discs matter.

I thought those trumpets were only effective when used in vacuum?

^ VA is pretty far, got a mountain of liquor?

I test-fit the deflectors and they do the job I need them to do blocking all but the bottom bit of tire due to camber, the install looks like it'll be a little more involved than I thought requiring removing at least the lip to install them but there's quite a few attachment points so they shouldn't deflect.

Picked up a pair of 3rd gen Saturn SL1s, one being a parts car and a steal at 250 bucks. Going to gut that and pour the parts into the other as well as my GF and a friends cars. Should only be a shell when we're done with it. If I had the time I'd refurb and flip it since there's a few bent? valves. Oh well :P

I wonder... that may be the case. We're going off the 'it works in intakes' idea, but since intakes are (mostly) in vacuum... do they hurt flow at pressure? I'd think not but maybe I need to read more on them.

Got the car aligned on Friday, thought my GV extensions walked away off my front steps but UPS had the wrong delivery address so I tracked it down to a house a block away. WHEW!


Trial fitment test. From the front, you can see both tires completely obstructed - I'm excited to try these out!


From the side; they fit the form of the bumper quite well, just need to get hardware to attach them and figure out HOW they attach, it looks like after predrilling some holes the lip goes onto the extensions first and then as one onto the car.

Got the alignment corrected after a short stint offroading from snap oversteer, no damage but the bolts did slip a bit so it had to be adjusted again.

My alignment bolts have slipped several times. My NB isn't working right now (otherwise I would try them) but Flying Miata now has an eccentric "locking" kit that is supposed to prevent that from happening.

Bedridden with the superflu, I had been planning on going to the MAP Proving Grounds. Le sigh :(

So! I experienced my second Main Relay failure tonight, not the best feeling in the world since I replaced the thing in July (16th to be exact). Going to order some spares...

Fuel pump on an aux relay? Maybe go with an aftermarket, higher amperage one like some folks had?

I have the DW pump wiring stuff, I just haven't had the motivation to install it. Probably something I'll be doing next Spring though to reduce load on that circuit. The increased loads from my DW300 are probably popping it prematurely.

Greased the bushings last night and found my rear upper inside zerks are reachable but I can't get the fitting to stay attached. I'll have to pull them and either put longer zerks in or clearance the material around the installed zerks to get the gun on the thing.

Also, the passenger side brake duct just barely dragged on the inside lip of the wheel and rubbed a small area through except the coils. Another thing to address next year. Le sigh~

Going to put my TSE EFR downpipe (for NA) up on the marketplace here soon. Probably going to sell the hardlines as well since I don't need them, will update here with a link once posted.

I had a downpipe made by an exhaust shop to get the car to FM, I don't think I'll actually use it and could use the money. The hardlines I'm on the fence about, nothing wrong with the parts themselves.

He built his custom DP before the production parts shipped.
