Front Splitter Endplates - Verus Engineering
 

We wanted to add another part to our line-up that adds front end down force. We wanted something that no one else had made yet, something effective, and something a bit sexy :cheers:. Below is what we designed, the predicted performance of the unit, and a few photos of the parts on the shop car. These were designed to go on our front splitter, but may be able to install on other units as well.

Design:
The front splitter endplates were designed to increase front end downforce of the vehicle for improved performance at high rates of speed. By creating a high pressure pocket of air above the splitter and in front of the front wheels, we are able to increase front end downforce. By reducing the airflow that hits the wheel head on, we also reduce the airflow into the wheel well and thus lift generated in the wheel well.

Like all of our analysis before, each analysis was done using a half-car analysis since no yaw testing was completed. This is done using symmetry down the centerline of the car. Significantly less computational processing power is necessary when using a half-car model and was the reason behind this analysis approach. The meshing of the car is done using first a surface mesh and then volume mesh. To find a suitable mesh size for the analysis, a grid convergence study was done. A volume mesh count of 10 million cells was considered within the room of accuracy using mesh sensitivity analysis.

Numerical Data:
The front splitter endplates increase downforce and drag according to our CFD analysis. The additional front downforce comes with a penalty of increased drag, however the l/d (lift over drag ratio) for this component is favorable. To put in another way, the amount of down force this part produces is significant compared to the amount of drag increase.

Conclusion:
With a bit of math, at a mere 100 MPH, these two pieces add an expected 40 lbs of down force to the car. These can be used to help balance out a rear wing or allow the end user to run a bit more wing angle for faster times.

As we have said before, real world benefits may differ as this is a computational analysis. Something as simple as ride height or wheel choice can vary results, as well as various other aspects. Real world results could be better or worse than what is shown above. Keep in mind we did NOT vary any of these aspects and kept it a very simple A to B comparison with the results outlined above.

Testing 3D prototypes. I used these 3D printed plastic units for about 2000 miles without issue, carbon fiber should be plenty strong.

We will have more photos soon with nicer wheels :thumbsup:.

These will be available shortly and we will post when FT-86 SpeedFactory and our other vendors place these on their websites.

ahhhhh so thats what this piece is! i saw it on ig, but just thought it was a piece stuck on the sides of a splitter. i was actually going to make one of my own, but more similar in design like the ones found on the ATS-V and vette and other GM cars.

woohoo! The parts list keeps growing! Awesome!

Do you think these in combination with the race splitter would be enough to balance out a wing like the APR GT-250?

There are the numbers that APR advertises for the wing:

I had been leaning towards running a 5 inch splitter instead of the Velox unit as I didn't think 3 inches would be enough but these end plates may change that and I like that they also function as mini fender flares for larger tires.

That will depend on what AOA you plan on running. Yes, these will help balance out a rear wing :thumbsup:.

The real question to ask is ... When is Velox will be selling their last piece of the puzzle ;) ? A Velox wing that match the splitter with endplate ?

Quick question. How are the aero balance (F/R)of splitter and diffuser on this thread is different from the aero balance posting on the diffuser thread?

Looks like we accidentally flip flopped front and rear on one of the data sets, I will look over our documents and correct whichever one is in error.

A close up picture with nicer wheels. Will get more as I have free time to take more pictures.

Looks like I swapped front to rear balance from the diffuser data in the diffuser thread. Will get with FT86 SpeedFactory and correct this, thanks for catching it.

Units are now on the website: http://www.ft86speedfactory.com/ft-8...l#.Vse3_fkrJhF

Few more photos as of recent.

Loving mine... and the wheel deflectors. Ready for warmer overnight lows so I can put my RPF1's and Direzza ZII's back on! Lots of front end grip even on my "winter" Continental DWS.

jesus Eric, you just keep pumpin em out dontcha?! lol

Im guessing finned skirts. Or underplate.

Doing our best. No longer a part time gig, this is my life now.

We have both in the works along with other aero development items. Time is hard to come by but more updates to come on all of it soon-ish.

:cheers:

I am very curious to see about the advantage of side skirts, but I would assume undercarriage would beat it easily ;)

Personally I vote for a VELOX X-WING ;)

My end plates came in today!

Installation was a breeze and I took her out for some photos afterwards.

I finally have a pic with my summers on... but it was right after a rain storm and the car is DIRTY... the dirt makes the endplates stand out more tho lol. I need to wash her and get some nice pics in a scenic spot!

Do you guys know if this can be installed over an STI lip?

Sent from my SM-G935W8 using Tapatalk

Potentially, personally know of one guy making it work with his *plastic lip of your choice* style splitter. It requires some custom fabrication but he states it made a noticeable difference in front end stability.

Oh nice. I'll most likely do the same. Thanks!! Time
to purchase mine then

Neat photo mash-up our web-developer did on his own car with our CFD picture.

Are there any other components you'd like to see us produce from dry pre-preg carbon as well? Let us know!

Functional canards.

Rear spoiler that can replace my Scion boomerang.....

Side skirts?

Work in progress, likely 4 months out though.

Boomerang?

3rd set of prototypes are due in shortly, these should be production ready in the coming weeks.

So by the time I can afford the splitter I'll have another couple grand of parts to buy... great... gonna need some kind of chart showing the functionality of the canards... maybe wind tunnel and track testing, and a deposition by at least one senator that they do function... Just to piss off the haters

We know they work, the real question is how much do they actually do? We're quite excited to undertake this project because we honestly want to learn more! There is not A LOT of data on dive planes and we hope to learn a bit by trying a few different shapes, angles, etc.

Not many people know this but one of the primary function of a dive plane is to help seal the side of the car with vortices, not actual front end downforce, though they generally produce downforce as well :thumbsup:.

We'll work on having all forms of functionality legality checked off as well :party0030: :party0030: .

Boomerang = Factory Scion spoiler......could also be called a bat'leth.....if your a star trek fan.

I would like something like this. http://www.ebay.com/itm/LRB-Speed-MA...9We2lZ&vxp=mtr

Mounting would cover the holes made by the factory spoiler, adjustment rods connected to a license plate frame mount.....made out of aluminum........just an idea

We made a slight revision to the end plates by adding our logo to the sides of them. These were out of stock for a few weeks but we now have plenty more back in stock!

Any questions, let us know.

Eric

I just ordered a splitter and plates from ft86 on Sunday. I haven't received shipping notification yet. Will my end plate thingies have the logo?

I believe so. We're back ordered on splitters right now, I have another order of splitters shipping out today to FT86SpeedFactory so I would expect them to start shipping mid next week.

Thanks,
Eric

Thanks boss

So where are we at on that Velox GT Wing?

Please tell me this is happening and not a sick joke. I am in the market for a gt wing and this comment has made me throw out all other wing options. Will not buy a wing till this comment is confirmed true or false. lol.

It was hinted at in another thread. I'm looking at selling my Rocket Bunny wing for Voltex but Velox would certainly be an option. If Eric made it mount like the RB wing I'd love him forever ;) ;)

I was just about to pull the trigger on a Voltex 1s within this week until I saw your comment.

Eric should be along shortly but I doubt he will confirm anything other than "they are looking into it". If you want it this year you should probably just get the Voltex and save the packaging so you can sell it later. Shouldn't take much of a hit on a Voltex wing

We've been developing a rear wing since the beginning of the year, we're trying to have first articles ready by the end of the year. It's our own design/profile, should be interesting. To say we have a lot of free time right now would be an absolute lie so if you're interested in a wing in the near future, I would, by all means, *not wait for ours*.

We do have a goal of offering a universal wing to compete against Voltex and APR units though, because who doesn't love an underdog?!?!? Learning a lot and should be neat when all is said and done.

Thanks,
Eric

man....how much products are you guys developing atm? I heard of a few but it seems like the list keeps growing! Now I wish I didn't get the sard cf wing yet...I may sell it in the future then. :D
