UTCC / Hyperfest 2018
 

We goin!
VIR May 18-20

Tire Rack Ultimate Track Car Challenge

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.

Bauce.

It'll be like this, right?!



Pumped to see a miata at UTCC. :party: 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 :D

Assuming the Full Course, we think 1:51 or so, depending on what congig we bring.

I am so mad it is the same weekend as SOFR, rally Ohio. I was planning on being at hyperfest this year. Oh well.

Hell yes, it'll be awesome to see you guys run! You just made me look forward to Hyperfest so much more.

weekend before I go to Greece, but might be worth going out this year. too bad it's not in my backyard anymore...

Gahhhhh can't wait for this.

Looks like our wacky Super Lap aero will just squeeze into ST2. R7's for that. A7's for UTCC. Think maybe a top ten finish in UTCC is possible?

I would think ~1:58-59 in ST2 trim and if you can squeeze out a 1:49 I think that would be top 5.

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.

We're wondering the same thing. Long ass 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.

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". :party:

I hope to make it over there late Thursday evening to camp and be able to catch Emilio and Ryan doing UTCC on Friday.
