I'll drive for UTCC, Dan and Sonny will team up for the NASA TT2/ST2 events. We're scrambling to get Vegas ready. For UTCC it'll run fool boost, make around 360whp, the Quafie sequential, 245/40 A7's and probably similar aero to what we ran at Superlap.
Back up plan if we can't get Vegas ready is to do the same prep to Bullet. No problems with Bullet but Vegas will be very more sexy time. Not sure of the final TT2/ST2 config but less front aero, 2250# and around 290 avg power with the sequential and same tires is a guess.
No idea how fast we'll go. Once we get the first shakedown done here, we'll issue a pointing-to-the-bleachers lap time to begin the talking of the smacks.
Pumped to see a miata at UTCC. I'll be up there that weekend to be a cheer-leader for you guys and I'll be running TTE over the weekend as well. Maybe upset Kohler's old record
Spare motor dynoed here. It's a PT points BP4W. So basically 9.95:1 stock flow with rods, pistons, oil pump, damper, valve springs, ARP studs.
23-25psi here. Bottom plot is the same hardware with the smaller W/G actuator for S1.
Now to install the whammy BP6D, +2 CNC, big cams, 9.0:1. Not sure how much more we'll gain but I'd expect another 40whp.
More flow so peak boost will drop 1-2psi which is good. Less static compression and coated chambers/crowns/valves/exhaust ports so we can probably add another 1-2° of timing.
VVT will help it to spool faster. Cams and head will pay off on the top end. Still, the PT engine has a 2500rpm wide powerband. Can't wait to unleash this thing on track with the Quaife.
Crazy top speeds at VIR! It’s gonna take some serious testing to determine the right amount of aero. I look forward to another solid showing by all of you guys.
I wonder if Aero drag from the 295’s is worth the penalty over the 275’s. It’s a whole new mind set at that track. All my experience is the right twisty stuff.
We're wondering the same thing. Long *** straights. We'll look at data when we get there and decide if we need to trim out aero. For TT, track position doesn't matter so you don't need top end speed. Entry and min corner speeds equal lower lap times. I'm thinking we'll want all the downforce even if it hits an aero wall at like 150 or something.
That wonderful aggressive Aero will likely be felt pretty early. Long before 150 IMHO.
I have no doubt you guys will optimize the setup and show up with another ringer. Sneak around the pits and see what the locals focus on. Downforce with little drag as possible would be my goal. Maybe spend some time on flatish bottom and diffuser stuff. With that you can minimize wing angle and drag.
Bullet does not have a flat bottom or diffuser. No offense but, I purposely ignore what other people are doing. Unfortunately the front arrow on Bullet is not adjustable. So if we reduce downforce, it's a one way street.
Frankly I'm excited about having all the downforce so even if it is a bit slow on the straights I will probably leave it that way.
No 295s on Bullet. It only fits 245 fronts.
We'll either run 245 square again, or 245/275 stagger if testing proves it to be faster with all this extra power.
I think the aero will prove to be super beneficial in.... the up-hill esses, I actually stay track left on entry to cut distance in my car. T10, the FAST left hander after esses. And hog pen(T16/17) which is of course important because it's the start of the front straight. I realize the crowd I'm talking to, so this is just me thinking "out loud".
I hope to make it over there late Thursday evening to camp and be able to catch Emilio and Ryan doing UTCC on Friday.
