Aero Ideas for Dirt Late Models and Dirt Modifieds; Our Cars are too Tight

[@yhites]

I think everyone talking about getting air under the car needs to also take into account the engine exhaust that dumps under the car. I believe the center of the car around the transmission is actually a high pressure area.

A really good point. That’s why a focus on getting the air out is as important as not letting the air in.

Great video. Totally agree with the left rear needing a bigger opening for air to escape. What about RR dynamic height being so low? Doesn't that contribute to the LF problem?

[@HoganTechnologiesLLC]

Yes, definitely. The RR height does affect a ton. I do go through what I think needs to happen in another one of my videos. Thanks for watching.

Drivers almost have to treat corner entry like drafting. Angleing their entry to keep the car out of dirty turbulent air left from the cars infront of them. The rise in sliders in my opinion is because quite frankly these cars today cant be over driven. And these new kids don't know that hesitant feeling of a car not turning.

I’m anxious to see how this plays out. Thanks for watching.

Check out Morans left front wheel well! lol

[@HoganTechnologiesLLC]

Found it. Yea, he opened it up pretty good.

I'm curious as to what speed aero take effect, or at least is a contributing factor. I drive a hobby stock. 99 Monte with a late Camaro nose. I feel there is an advantage, but at what speed?!

[@HoganTechnologiesLLC]

I think there is always some effect. The faster you go, the more of an effect.

The large left wheel wells i think would cause more air to be drawn through causing more drag like they say with driving a pickup with the the tailgate DOWN actually makes gas mileage worse.

[@HoganTechnologiesLLC]

I agree with making the right side wheel wells small to not let the air I, but I think getting as much air out as possible is a benefit. Years ago Josh Richard’s showed up at Screvin, I think was, with ½ the LR quarter panel missing. He was clearly faster. They made him correct it and the car slowed down. I think there is something to getting as much air out as possible.

I'm sorry but this has been going on for years, back in the early 2000 when I raced open motor modified there was one guy that did this all the time until he tried that on me, I broke him on doing the slide job after he found his self backed into the uke tires and out of the race and he had the nerve to come to me and ask if i wrecked him on purpose, my reply was yes and I'll do it again if you can't pass me clean then don't slide me !

[@HoganTechnologiesLLC]

I when I first came into late model racing,stuff did go on, but there seemed to be a lot more respect. No one wanted to tear up cars like they do now. I don’t know where this slide job culture is going, but it interesting to keep an eye on. Thanks for watching.

Great video, I am not from the USA, and I am not familiar with the dirt late model rules, but is there any rules that forbid paneling in the underside of the car and running a diffuser?

[@HoganTechnologiesLLC]

I’m not positive, but I think there is.
