Nice JJ! pretty awesome wing there
So the speedway was interesting. First time with the race car on a Roval. It was more interesting than I originally gave it credit.
While heat cycles are heat cycles, there's nothing like a perfectly new and groomed NASCAR/GrandAm track to leave your heat cycled tires looking nearly new. Was a shame removing all that nice looking rubber, but times fall off quick with heat cycles...
When I built my wing uprights, I did not build adjustment that would allow for anything less than 7 degrees of rake. My initial concerns for top speed and this aero package turned out to be a bit less of an issue. Since I couldn't flatten out the wing, the aero drag was enough to keep the car just under 150mph (5mph shy of redline). The vipers in ST1, my sister W2W class, whom I compete with for the overall, don't have near the aero drag and could flatten their wings out to 0. They were runing 10-15 mph faster than me on the oval. My aero drag stalled me at about 8100RPM in 6th for nearly 8 seconds!!! That's a lot of time to lose to another car that's still building speed. Good news is that I made up a lot of time in the infield. Ultimately, I won my class against the GTRs but missed an overall track record by 1 second against the vipers
... I've taken the overall against them this year a few times, and if there was ever a track I would lose to them it was this one.
I did try pulling the wing just for giggles. Now, if you're thinking that was a bad idea, you'd be right... really right! --- but you don't know until you try
As you would expect, a new top speed was met with fantastic enthusiasm bouncing off the rev limiter! Shortly following the top speed (rev limit) the car became nearly uncontrollable and threatened to kill me. The car jumped down to the flat below the banked oval and then back up on to oval--- all at 155mph! It was a trip, lol! Of course the result was me pulling off and into the pits. A lost session, but answered a question and gave me a part to change for the future, ie. need more wing adjustment.
FTR and to save some face, "Lips" pulled the wing on this NA TTB Elise, picked up 8mph and lost 2 seconds... All good things. So I had some precedence for pulling the wing, but our aero packages and speeds are MUCH different, so no real surprise in the different results. Good data for the NA TTB car though!
Engine and trans loads were high with the sustained WOT, RPM, and MPH. Again, the car performed without incident. It's been essentially an arrive and drive car all season and couldn't be happier with the performance and reliability!
