Atleast i'm not the only one who knows about that. I tried telling Robbie about that. he called me stupid

Basically get the lowest pressure in teh engine bay, and the make sure all the air goes through the radiator.

what about an aftermarket belly pan with louvers, and or front splitter

Your belly pan you have now will have louvers soon if you don't stop bottoming it out on the road.

Yes, I'm jealous that I can get where I need to go without tearing the hell out of my car and having to worry about a small rock ripping off my oil pan.

It looks sweet, but totaly unpractical.

It's a fucking N/A, stock miata. How hot could it fucking get?

Btw.. the hood risers are one thing that stuck out to me. I think it looks horrible like that.

its different and i don't see that many people with them, and i think its amusing when people come up to me and ask me is there something wrong with my hood

Yeah, hood risers are different. It looks like you got in a wreck and didn't fix it right. Way to be different. lol.

BTM · 09-08-2007, 01:30 PM

damn people, get off the guys back!

**Kevin Doe** · 09-08-2007, 01:40 PM

Brent, I'm not on his back, I'm just telling him that the hood risers aren't serving the purpose he thinks they are. They DO NOT allow air out of the engine compartment.

They are bad for a few reasons. You want the underside of your car to be as low of pressure as possible. This is for both aerodynamics, and downforce. Minimziing pressure under your car basically means restricting the amount of air you let down there. Hood risers allow high pressure air to enter the engine bay, and thus the underside of your car. Not good. Since hood risers also increase the pressure under the hood, the differntial pressure across the radiator will be lower, adn you'll get less airflow across the radiator. Not good.

I guess if he just wants it to look differnt, then so be it. But with those negative aspects I listed, I think its just stupid. Doing it for looks, despite the negative performance aspects would make me call him a ricer.

BTM · 09-08-2007, 01:47 PM

yeah i guess you are right, but hey, if the guy wants to do it despite the bad then so be it.

care to explain what a front air dam or splitter is? and how to effectivly make one?

yes your right i used them thinking they would help me and in fact they did the opposite. now i know this thanks to the knowledge of kevin doe. i just have one question, is the rx-7 done yet?

**Kevin Doe** · 09-08-2007, 02:27 PM

LOL, no. Brent, if you want to swing over, I'll show you everything that I talked about on my car. I have incroporated all those conecpts into my RX-7 and could show you much easier than I could explain it on the net.

I was looking at the Beat Rush underpanel for my Evo, if they make one for your car then yes that would be a good mod. Splitters work great on the race track but aren't very practical on the street if they are low enough to be effective.

Drop that hood back down and in N/A form your cooling system is more than sufficent. I had to duct my radiator and and seal the radiator to the core support with foam insulation on the DSM, but only because I have more than doubled the original power output and thus heat load on that engine.

**Kevin Doe** · 09-08-2007, 04:50 PM

^ And added restriction becuse of the intercooler etc.

the beatrush underpanel is something i have been looking at for awhile, just don't if its worth $170.

redmike · 09-09-2007, 09:53 AM

Doesn't look like it covers everything very well.

I'm thinking you could make a template yourself and have it fabbed up cheaper than that?

I would try to bring it up to the edge of the bumper for a better fit. And try to make it as wide as you could and still clear the wheels at full lock. Looks fairly easy to fab up. Thought about doing it to mine, but his looks way easier.
