A few years ago I tested end plates in the A2 wind tunnel. The data shows that there wasn’t much difference between them, and I may have drawn some hasty conclusions about that.
The fact is, a hatchback with a 55” wing is not the ideal playing field for this type of competition. The combination of a short wingspan and an odd C-pillar vortex coming off the hatchack roof may have polluted the air right next to the end plate. So this really needs to be tested again on a proper coupe or fastback.
I’m going to the wind tunnel on 5/18 and 5/21 with two good candidates, a BRZ and a 944. We’ll be using a much wider 68” wing, and will test end plates for realz this time. (Also, I may have space for one more car, contact me if you are interested.)
So here’s an open call to everyone who makes an end plate for a 9 Lives original (now Express) wing with 4 holes on the end. Send me your end plates and pay for return shipping, and I’ll send them back after the test. I’ll publish the report and send you a copy for free.
I don’t want to leave anyone out. So if you don’t make an end plate specifically for this wing, but you want to be included, I can drill and mount your end plates accurately, to your specifications.
