I think this qualifies for most badass NA out there (at least based on looks). What sort of stuff is used to make that lip? It kinda looks like some landscaping trim, except the edge isn't rounded.

Probably some sort of abs plastic. My buddy did that because he was getting front end lift on the track (130mph +). Got some abs plastic and molded it to the front. Helped greatly.

I like those scoops...anyone know what they could be?

NACA ducts, you can get them lots of places. Pegasus racing carries them and there's some other places but I can't think of them. I'll be doing those in the front eventually for brake ducting. Another in the triangle window for some air to the driver too.

after you ship my stuff to me I'm going to talk an insane amount of shit to you on the internet. Seriously, get the suicide note ready.


I'm going to do the splitter/scooper shit, then see what happens. Hopefully I can make it through a session.

Someone should buy it, then. The car's been for sale for a few months now. Canadian '94 BRG, fully caged, T3 setup with an AEM and a DO Progressive kit. Gorgeous car. It was my roadster muse when I first bought my car. I codrove it at an autocross last year and it's fast as hell.

How much is it?

I think he wants 10k for it. Don't recall exactly.

Try to find me that link/listing/where I can get moar info. I may know someone who was looking.

Why do I only see TNa.

As far as the cut out on Sav's car, You did a good job. I would probably get black door trim and place around the hole to make the edges smooth and uniform.

You may have already done that, I didn't read all 7 pages.

Todd, could you tone down the straightness please? It might offend a few people.

I wonder if some straighteners would help move air through the heat exchangers too?

Do we actually have anyone here who's running a sealed/shrouded radiator, without a cut bumper who's seen the track?

GT3man...se the useless metal above your tow hook? Cut that out with a sawz-all and hit the other side too. You'll move lots more air.

I wonder how those NACAs would look painted to match? I could run a 2-hole NACA for the oil cooler and it would be really easy...but will it move enough air for a 24-row 6x10" heat exchanger?

Never thought of that. I'll be sure to do that this weekend. I have the front bumper off of the car right now for paint.

I swear you ask so many dumb questions. You seriously don't believe what anybody tells you. 10 fucking engineers that did the aero aspect of the miata could come here and tell you what will improve it and you'd still doubt them.

How bout this: Stock radiator, 20x12x3 core IC sealed in front of it with the stock A/C condenser sealed to it. Stock NB shrouding. I can cruise at 70mph all day long A/C blasting and make pulls up to speed and it never thinks about overheating. I can sit idling with A/C on and it's fine. My shit works. I think you should do what I posted earlier with regards to ducting. Maybe others will comment on its effectiveness. Here it is again...

i'm following your advice and doing this set-up. However, I'm going to move the oil cooler to the other side of the car for convenience, and I'm putting brake ducts in the air-dam.

Why don't you understand that stomping on the gas in 5th gear is different from tucking behind a train in 2nd and 3rd gear for laps at a time? I'm tearing up the pegasus catalog right now too.

R.S. Aizawa? or my Vary bumper?

I'd be willing to bet that if you did nothing more than put a big fucking fan on that radiator the engine would never overheat. You don't believe this though. But it's the fucking truth. A big 25 or 30A fan will pull so much fucking air through that radiator the car will lurch forward at a red light when it comes on....

Or if you did the shrouding like I showed it wouldn't overheat with stock fans. IMO, adding scoopers and ducts to get more air to the front is a joke. There's plenty of area up there for all the air you need. You don't race at 3 mph. Most of the air that hits the front of the car doesn't go through the mouth. It goes around it. Putting a bigger opening won't do shit. Putting a scooper won't do shit. You have to do things to make air flow. Pressure building up in the engine bay doesn't help flow through the heat exchanger. So adding 4 times more frontal area to the mouth just causes more air to built up under the hood.
