airflow testing

had some dry weather today for a bit of testing.i rigged up a gopro to show the bottom and some of the upper lip.i placed 3 strips of tufts to show how attached the airflow is on the bottom center where it transitions back to the chassis flat bottom.you can also see the high pressure area on the top side of the splitter.the tufts kinda dance around.i have 1 more video i still need to edit.it shows the upper side pointed at the tire flick.i will have that one up soon.i hope the utube works.its my first one.

You should shoot one with no splitter if possible, with the tufts in as close of the same location as you can manage.

topside

alright,ill try and do that when i remove the splitter.its going to be on for a bit though.here is the topside video.i was trying to capture the tire flick area.you can see it if you go full screen.im going to try and install the imrp diffuser today.i have a good feel for how the splitter is adding down force.so the larger rear diffuser will be interesting to try.today is the last dry day we will see here in the pacific northwest for over a week.so i will be logging some miles.

i've read through this whole post, forgive me if i've missed something, but Kevin, is your splitter to be used in conjunction with a rear spoiler? seems that the df applied to the front is changed quite a bit..? are your working on a companion piece for the rear to work the downforce together?

I'm sure it would work better if it was in companion with a rear wing, but with a weight distribution of 39/61 (f/r) with a driver from the factory, it really helps even that out so the weight is centered more on the front tires and make the vehicle more planted than it otherwise would be. Just my 2 cents.

thanks guys.

i was prepared to add a rear wing if i needed it.but after driving the car a few times.plus i added the big imrp diffuser today.the car just sticks like crazy.anything over 60 mph you can feel it working.the feel is very neutral too.today i was taking corners at 75 and the car was just stuck to the road.on slower speed corners under 40mph i could feel the back end step out a bit.those speeds are purely mechanical grip.at this point i feel you could run this setup without a wing and do pretty good on the track.maybe a Gurney flap on the rear clam would add just a bit more df without adding a bunch more drag.so now i have pushed it as hard as i can on the street.i need to get a splitter to one of the guys that runs a track regularly.then add the splitter to see there impressions.i look forward to hearing how other people like it.i will be starting production tomorrow.i finally have all my materials here.

This has been needed so badly. I can't dial in my ARP wing much at all. More for looks (and drag!) as it stands (pun) now. You are going to be a busy fellow.

Actually, for that view, I didn't even need the tufts to see it working. I can see the lip flexing down slightly as you pick up speed, which is enough evidence for me! Not to mention the increased airflow to the radiator (the air that used to go under now goes up into the mouth.)

so do you have to much rear grip?do you have a splitter on the front now?i feel that adding more front aero will be a big benefit.i will also be doing dive planes that will mount low.possibly on the tire flicks.these will be for tuning and slower speed tracks.i wont be able to get to these for a bit.i have a lot of orders to fill.

yea there is just a bit of flex.you can see it pulling down slightly.i have a fix for that too.i added 2 threaded spacers between the crash structure and the splitter back about 10 inches.these are located just behind the plinth.so i will add one more just behind the plinth in the center.im pretty sure that will cure that slight movement.these spacers where needed to tie the clam into the crash structure.without them the clam is only attached at the headlights.so it would just lift up and down.your right.the airflow to the rad looks really good.the tufts get sucked right into it.

Can you ever have too much grip? More a matter of balance. If much wing is applied, car is "tight" per the vernacular of NC. Current front aero is per Esta. I'm sure it is not as effective as is needed.

yea,balance is key.you will need to add some front aero.that apr wing is capable of producing a good amount of df.its the one i have been eying for myself.

just building splitter parts.i have a splitter top in the oven right now.in a few days i will have the 2 e glass ones ready to ship.i need to place a large order for all the hardware that these will use.plus i need to write the install directions.so there is plenty to do but progress is being made.i also have the test splitter to offer someone.i need to email ztec to see if he wants it first.he is on top of the list.he was also going to do some track testing for me as well.this one has the light wood core.so its maybe 2 pounds heavier than the nomex splitters.

as for the carbon splitters.i have been doing the eglass ones first to get a feel for the layup.the upper part is very complex.so now i have a better idea of how to lay the carbon ones.these will get done next.

YES!

so since I am 2nd on the list for the eglass one.....

when do you think it will ship Kevin?????? Inquiring minds want to know.

As for testing mine will see the track very soon after install. I am looking at 12 maybe 14 track days this year so I sure hope it proves to be a robust piece. The first is this weekend! but the splitter wont make it for that.

well,if you where to take the wood core one.i could ship that one early next week.or if you wanted a nomex core splitter.that would be a few days longer.im laying up the bottom pieces for them now.then they will need to be trimmed and glued together.i will have the weight difference between the wood and the nomex in a day or two also.
