The "Big Wang" test


As you might have heard we started selling wings. What you might not have heard was that we tested the Big Wang vs an APR 200 wing. The interesting part was, If our wing failed to beat the APR200 we would scrap the whole Big Wang program. The thought process was, to offer a wing that's worse than the industry standard would be pointless. We at Nine Lives would also like to express our absolute respect for APR they are valued competitors. On with the test.  



The test car was our V8 powered Miata. We've run this car for 5 years with the APR200. Everything on the car was exactly the same between tests. Same tire psi, hell... even the same oil! The only thing that would be different would be the tires' heat cycles. The big wang's tires (Pirelli P-zero dm)had 10-15 heat cycles as the APR's test had fresh tires. 
  


Test location was good old Road Atlanta. Our home track with lots of data on file.

Weather 
Warning: Our tests were not done on the same day. Take that for what you will, but conditions were close enough not to find any reason to void the results. Both where 65* and sunny at test time. Barometric pressure was 30.1 for the APR test and 29.9 for the Big wang. A difference of 0.1. (Normal daily barometric pressure shift is +-0.5) 

APR's data came before we were encouraged to do the "Big Wang" program so test driving is unbiased.   

 The Subjects 
 The two test subjects were a 60" 'APR-200' ('new 200' standard Miata) and a 66" Elan made 'Big Wang'. We picked the 200 to test with because both wings were set around the same retail price. APR 200 is $935 retail, ours is $686 w/Optional R-Theory mounts. 






So like any good test, we formed a theory and tested it. 

 As you can see above the big wang was a whopping 6" larger. This raised a few questions for us to base our test on. 

  • Bigger Wing = more/less drag?
  • 3d (Twist) style vs 2d = more/less downforce?
  • Aluminum v Carbon = weight play a factor?


The test 


The first question was if the Big Wang's extra 6" would increase drag. Drag would affect the car's ability to gain speed. The evidence we'll use is the effect on top speed, more drag = lower top speed.

The result: Big Wang had less drag! 
 Evidence below. 
APR 200 top speed 156 (AiM solo DL detected 157mph) 
Big wangs top speed of 159mph 

Test notes: We gained an incredible amount of speed. 3mph from a wing swap is a huge performance advantage

Next question was about downforce levels. 
for this, we selected turn 12, Road Atlanta's fastest turn. 
The result: Big Wang had more Downforce! 
evidence below. 

 Corner speed at turn 12 was 107mph 


Corner speed of the big wang was 109  (other laps we saw as high as 111mph)


 Test notes. we noticed a significant amount of stability with the Big Wang. We were able to 'keep our foot in it' for much more of the track. 



The final question was about weight. 
Carbon vs Aluminum. Carbon will always be lighter and stronger. Our wing weighed in at 0.2 lbs_per_in. The apr weighed in at .14 lbs_per_in.  A difference of just .6lbs_per_in. although our wing was heavier, it wasn't that much heavier. Elan really did their homework and made a well-performing lightweight airfoil.   

Test notes: 
We didn't notice any added body roll from mounting the larger wing. We were paying attention, if we did, we would notify customers of what to expect.  





Final Thoughts
We went the same lap times between the two wings. Considering the Big Wang had tires that were into their 10-15 heat cycle we considered that a point for the Big Wang. Overall the downforce was astonishing. We had the APR set to its maximum aoa at 15*. At this angle of attack, we couldn't get it to overpower the front splitter. The Big Wang was able to overpower the front splitter at just 2* aoa. We wound up running the Big Wang at -1* just to find a balance in the car. At this point, with The Big Wang, we can start adding a lot more front downforce to take the car even further.

Testing speed parts at speed. MSD Atomic Intake, 105mm Throttle body and Pirelli slicks.

Test time. When you run time trails every time you take the track it's test time. This time we take the time too look for time.... ;) We installed a MSD atomic intake, paired to a 105mm Holley Throttle body on our 5.7l LS1 engine. We also tried out some slicks.




This was our first event trying out the Perrelli P zero DM. fitting 225's to 9" wheels was a real pain. these tires did not want to go on.  DM's are allegedly Pirelli's Time attack tire. super sticky.





We also bolted on an MSD atomic intake W/105mm holly throttle body. we had lots of people reaching out to us warning about our TB size choice.  Lots of internet rumors about drivability on such a "small" engine. We also needed to grind our Corvette water pump to clear the intake. 





The lat thing to test was CCP fab Fiberglass doors. already proven to remove 60lbs from the chassis. 
  


With the updates installed, we sent her out on a flier. 






Results!

 Intake and TB.
 Reading the internet gossip was quite intimidating. A constant barrage of "you'll lose driveability" came our way. We aren't sure if they were wrong or if the tapered bore on the TB was that big of a help. Despite all of that we didn't notice any mid throttle hesitation. Mid range pulled just as hard as before. On the top end, we did notice a huge gain in top speed. Previous peak top speed was 155 we where now trapping 157. a 3mph gain is a big deal on our cars with big wings. Overall very happy with the results. 



Tires. 

This was our first experience with "real slicks" Data shows that we were peaking at 1.5G we will compare this to our Maxxis tires that are normally peaking out at 1.3G. a 15% gain. The P Zeros gave us 3 great laps, after that, they were a bit hard to control and needed to be cooled. They did take 2 laps to heat up, a solid lap more then any other tire we tested. Release and brake away was sudden, but not uncontrollable nor shocking. Overall these were very easy to dive very fast.  The second day of running the P zeros was not as fast as the first day. looks like they we already had grip falling off, this was after the first 8 heat cycles. A big punch in the gut after finding out how much they retail for.  The maxxis... old trusty... have lasted us a good year, 80 heat cycles,  and still peak out at 1.3g. going forward despite the time gained we will switch back to the Maxxis to keep costs low.  
 We have heard rumors of a stickey-er Maxxis coming out. 

Times are in. Previous fastest lap set on the same day in 2016 was a 1:34.8, new fastest lap set on 2017 1:32.8. A huge improvement. This puts us on par with corvettes with similar tires. our advantage is much lower operating costs.

Conclusion,
We are keeping the doors and the intake. but going forward we will be switching back to the Maxxis.  




       

Daytona didn't go as planned.



What is that smoke coming from? oh ...... 

About 3 years ago we had a chance to drive under the lights with USCA. The Miata blew a diff seal and we never made a lap under the lights. Exciting news to hear that David Murry Track days, this year was running under the lights. Super stoked to finally check the bucket list we packed up and headed south.  





 Landed in Datona around 1pm. Normally driver meetings require a 5 am wakeup. not this one.  We could get used to tracking days like this. 




The Drivers meeting ended around 3pm and the sun slowly went down. 


After the first Dusk run Fire erupted. Our Dry sump tank vent clogged, pressure built, blew the dipstick out, along with 3 qts of oil and it coated the headers. 




 The real hero was the Little 2lbs fire bottle. Without it, the fire would have grown. It delayed the damage just long enough to allow Daytona Fire to put it out. I owe those guys a lot of beer.

Here is the little Hero in all his glory. If you drive without one of these your an idiot. buy one a link is above. don't be an idiot. A billy bad ass fire system and another one have been ordered for the Miata. 



I thought I was done. The Boys from Mosler motorsports said: "You're getting the lights" and jumped into action. 




Damage was only cosmetic, the car ran fine. We were worried about damage to the tire. So the last few laps were super slow.  but we got the lights. 





Thank you- My wife Andrea, I know i scared the hell out of you. 
Mosler Motorsports (part of Nine lives racing) for kicking me in the ass and making the car work.
 OG racing for employing me and giving me the safety gear I need.   

and to all of our partners. Holley performance, Maxxis tires, PFC brakes 

CCP Fabrication -Miata Doors review with video.

Doors are on! 
We went down to CCP fab and ordered some lightweight doors for or NB Miata - v8 car. The first thing we did was make a quick FB live un-boxing video, next was to install them. 

The Facebook live video. 




Old OEM doors off. These are 'Gutted' NB Doors with Lexan triangle windows.  The steel doors came out to a whopping 29.6lbs on our handy-dandy bathroom scale.



As you can see not much remains of the original door. Just the bare necessities. Amazing to think this is 29lbs.



The new CCP Fabrication doors. The first impression was 'wow' at how light they are. The second was I thought I could snap them in half. When you're building a race car you sometimes need to build an item a bit more fragile to lose mass and gain speed. I'll keep my tubular control arms. Over the long run, that's where we want strength. The doors' strength is less important. The material is very thin. We found on accident that that light passes through them. A shop light surprised us with that discovery.


The big payoff. 5.6lbs. They feel almost weightless.




Excuse my mess. The shop is full of projects right now. The doors installed easily enough. Uses factory mounting points. OEM latches, Strikers where all reused. Install took a few minutes.
