Wing vs No Wing - Can a cheap aero kit produce downforce?

[@StudioVRM]

Some more background info for those of you who are curious - The wing is 57" between the endplates and was run at a 1 degree angle of attack as measured from the flat underside of the wing. The splitter sticks out 3" beyond the profile of the front bumper as viewed from the top, so it is pretty substantial. And yes, both are strong enough that I can stand on them.

[@countryguywithcamera]

StudioVRM add in enough power on the rebuild to make up for the added drag. As well as tape gaps in the car lol

[@alexdumitrescu3068]

VERY well put together assessment of the application of wing/splitter combo. I especially appreciate the critical assessment of positive AND negative effects. Oil starvation is brutal and is easy to attain with sticky tires and higher G's. Thank you!

[@Speediesam]

One of the best areo videos on KZbin. You compared the same car, driver and tires…. You broke it down into slow corner and faster. And to end it talking about oil starvation brilliantly. Which is a huge problem in my world of BMWs…. Great content

[@StudioVRM]

Thank you! I'm hoping to do another one of these in the future, this time comparing our DIY kit to an off the shelf kit with a more expensive wing.

[@Speediesam]

@@StudioVRM yes and yesss please!

[@theluckycatcollective8788]

I love this kind of direct comparison! Thank you for your hard work

[@davidkris]

So sorry about your engine. Thanks for the great comparison info. First video of yours I've seen, and subscribing immediately. Looking forward to finding your videos of the rebuild.

[@Clint_Moto34]

Damn this is really well made! It's so informative and great to understand/watch. Thx for sharing! :)

[@ElectrifyingRacing]

Roger - we absolutely loved your video!

[@tractorback76]

A good general video man! Well put together and great comparisons. Here's another negative of a splitter, going off track can result on it smashing into the radiator etc and ending the day

[@dtmracing13]

Learned the same lesson about oil sloshing at WGI. #4 Piston decided it was unhappy with the working conditions and left. Spectacularly. That's when I purchased a baffled oil pan that holds an extra quart of oil to boot. I just got the same wing your using, thanks to your recommendation. I'm going to fab my own end plates out of poly carb though, mostly because I hate the look of these. lol. Hope to meet you at the track!

[@nthk4u]

Great Vid. What was the overall lap time difference?

[@StudioVRM]

It was about 2 seconds over a 1 minute 35 second lap. We've made quite a few refinements since then and it's even more of a difference now.

[@Bruceanddenise]

SOLID information, backed by DATA! Sucks about the motor but appreciate you sharing your experience. Hopefully, save someone else the headaches! Thanks!

[@marioelburro1492]

Trying to learn about aero so i can install it on my car one day. Looks may be cool but it'll be even more cool knowing it is actually functioning (if done right). I wont be racing but i love how aero works, thx👍🏼

[@HoustonSpeedFreaks]

Loved all the information! Very well put together video😁

[@johngalt7232]

Thanks for the side be side comparison. Sorry to hear about the engine.

[@DANTHETUBEMAN]

Vary practical video, good information, nice experimentation for regular street car people.

[@NicksStuff]

Was the chassis setup identical? The balance of the car remained the same?

[@StudioVRM]

The chassis setup and alignment was identical. It actually felt more balanced and natural without the aero, because that's what the alignment and suspension was set up for. We made some alignment changes to the car since the video was made, and the car feels much better (and is even faster) now.

[@aacar4095]

Great video! Extremely informative. Lots of power + lots of downforce + light weight = fast = F1 😉

[@TheLibertyTech]

Great video mate 👍

[@johnturner39]

What were your final fastest times before and after aero?

[@racett5316]

I WANT TO KNOW TOO THE TOTAL

[@bbdetailing9123]

Good stuff.thank you!

I found this video fantastic.

you can do this even cheaper! glues some dead birds onto your trunk and some axe heads on the front. thank me later ;-)

Sick video

[@soconoha]

Hi there, great video! Any pointers on stiffening the wing with the epoxy? I've got the same one and hate how flimsy it is. Is it as simple as drilling some holes and pouring it in? Thanks for the videos and your time!

[@StudioVRM]

Thanks! I detailed what I did on this page on this page here: studiovrm.net/racing-secrets-blog/how-to-make-a-cheap-wing-that-produces-downforce/ Hopefully that clarifies things a little bit. Basically I used a two-part polyurethane foam and poured it in a small amount at a time. The polyurethane is lighter than solid 2-part gel epoxies and it expands so you don't have to mix or use very much. My wing had cracks from previous use, so I sanded and filled those with a two part structural epoxy, similar to what you would find at your local hardware store.

[@soconoha]

@@StudioVRM awesome, thanks for the info!

Splitter and air dam will reduce drag.

[@idriwzrd]

Anyone else see the pushrods come out from under the back of the car?

[@Fred_the_1996]

Virgin pushrods peek out vs chad me: piston comes flying out and destroys the engine 😎

Big Aero, little turbo and try sump oil pan.

[@the_rush_to_nothing]

[@racett5316]

WHATS THE TOTAL TIME SAVED BY AERO?

[@StudioVRM]

At the time of filming, the aero was worth a little over 2 seconds on a ~1:33 lap around NJMP Thunderbolt.

[@AstroCreepSpeedShack]

2 seconds total is great! I was blown away when I did a very similar setup on a much different car a few years ago and saw an average of ~5 seconds a lap faster at both VIR and PittRace. Cheap and maybe not the prettiest, but EFFECTIVE!

[@WarriorOfEden3033]

Exactly why the GT500 has a oil catch can

[@sepg5084]

Catch can does nothing for oil starvation induced by lateral acceleration, it just catches the oil (among other stuff) from engine blow-by.

[@WarriorOfEden3033]

​@sepg5084 then why did they install it to solve that problem?

[@danisherhan]

should've installed DRS

[@StudioVRM]

Oh the tech inspectors at impound would love that. It's so far outside what'd allowed in our class that their heads will probably explode.

[@NicksStuff]

What did the timer say over the full lap?

[@StudioVRM]

It was just over 2 seconds faster, bringing a 1:35 lap down to a 1:33.

[@grippgoat]

Hoosier? Whose👂? 😂

[@jdmorris9578]

Great video. This demonstrates my thoughts on wings, on the street they are useless.

[@sepg5084]

You can say that almost anything is useless on a street except for people-mover vehicles. Not all public roads are "streets".

[@danteeightsix]

Aerodynamics don't make your car faster, they make it to where you can handle the car better at higher speeds.

[@WarriorOfEden3033]

Aero changes depending on application

[@shredandenjoy7311]

Buddy, you can't claim there's not much a difference through two low speed turns when you dropped .39s! That's the better part of a half second in just two turns, and not high speed turns either! It's also important to note that "gap" through low vs high speed sections isn't terribly indicative of much. A 1 second gap is going to visually be different from 60 to 90 to 120mph, despite not having actually gained or lost any ground on the trailing car.

[@StudioVRM]

You're not wrong. This script was written with track day and DE drivers in mind, where people tend to be a little less concerned about a few tenths here or there. The gap through high speed turns was fun to illustrate because it looks so dramatic on video. That said, where you make up your time matter quite a bit in a wheel to wheel race. Most club racers can convert an advantage through high-speed corners into a position or two and hold it through the low-speed stuff. It's a little harder to do the other way around.

[@shredandenjoy7311]

Fair point! Still, for time attack folks, it's worth noting that is the kind of gains folks are pretty happy with!

Not surprised you say that.

I've never witnessed anyone call an actual racecar rice. Some people have no idea what that word means.

[@pab702]

It’s a track car. It’s not a show car or even a daily. Plus all of his mods serve a purpose.. to shave time of off his lap times.

[@sepg5084]

@@zelda7ase nah. A lot of people call asian cars "rice" whenever they want to. There will always be haters
