  1. Race Tracking Your Supra - Information exchange

    I agree that bigger is better, but that's also when comparing identical airfoils. I don't know how much difference the airfoil itself makes, but I'm fairly certain it accounts for something. Not necessarily just in total downforce, but maybe the downforce curve, L/D etc... Perfect shot

    That'd be cool thanks man. So why'd you choose the Fulcrum 14 over the Zeb 330?
  3. EdgeOfSanity's weekend track day build

    Front bar is better than no bar. You're introducing adjustability to the front (assuming it's adjustable...).

    Is that image legit? Where's it from? the Fulcrum 14 looks a lot flatter than that in pics. I could be off though obv since they're just pics By "pay for it" do you mean literally? Because they seem to be priced similarly

    Posted this in my build thread, but nobody checks my build thread, so trying here.... i've been going back and forth with both AJ Hartman and Zebulon to eventually replace my wing. Specs: Current: APR: 67" length - 10" chord w/APR gurney flap & Singular Motorsports Endplates AJ Hartman...
  6. TBK's Time Attack Build: MK-BRX

    General updates: Time to renew the registration, which means it needs to pass a test. They're quite strict here during testing, and the rules are really vague. So seats/exhaust/steering wheel/splitter/diffuser will all come off, along with any small decals i have. Back on when after the test is...
  7. Traction issues on e85, 45psi boost

    I think I found your problem OP
  8. TBK's Time Attack Build: MK-BRX

    This fits under the infotainment screen. Just disappears, with the ball sticking out on the right side. And the ball then connects to this mount that holds the catalyst I've tried many different combos (i think 5 at this point), and this is by far the one i liked the most. Does it...
  9. TBK's Time Attack Build: MK-BRX

    The data science nerd in me is def excited to check something like that out.
  10. TBK's Time Attack Build: MK-BRX

    Unfortunately i don't. I keep forgetting to set up the camera on the Garmin. It's there, i just need to calibrate it. Takes a second, so will get to it. The Sector:One guys have a lot of good vids on yas. Here's Jack in a 488 (Corkscrew Layout) Yash in a stock Supra (GP Layout)
  11. TBK's Time Attack Build: MK-BRX

    Expanding on the tune side of things a bit. Comparison between the old tune and the latest revised one The old log wasn't great, or long (and was on the street vs the new one being at the track). Hence low number of frames for example, but should still be at least somewhat representative...
  12. TBK's Time Attack Build: MK-BRX

    Yesterday's track day was a success. I set out to with the intention of logging, and testing aero/suspension/alignment. Conditions: I was on dead 295/30 CRS tires, and it was day after it rained, so was very dusty and slippery. No rubber on the track. Way too much traffic, so couldn't get any...
  13. What did you do to your Supra today?

    Oil coolers work man. Will absolutely help with oil/coolant temps. My coolant temps at the track today were almost too low (ambient was about 70)
  14. What did you do to your Supra today?

    An oil cooler?

    Nankang recommend 34-40 PSI for anything over 3,050lbs. So if we were to go by their reco, we'd be in the 36-38psi range, which def won't work for me.

    Struggled to get the tires properly warm last time around, so I'm also going to lower my cold pressures. I usually target 34 warm, but also considering going down a tad. So looks like you're pretty much in the same ballpark in going to be testing tomorrow.
  17. Race Tracking Your Supra - Information exchange

    Folks who run 200tw tires. What warm pressures do you target? Also, what do you (not the manufacturer) consider operating temps for that tire?
  18. TBK's Time Attack Build: MK-BRX

    Track day coming up tomorrow. Should have a revised map by then, hopefully something more linear and consistent. It's always been such a mad rush that i've never really had time to take a race-ready setup for testing. Tomorrow should be the day i get to do that. Game plan will be to gather...
  19. TBK's Time Attack Build: MK-BRX

    Yer, i'm just really confused as to how Sameh could even let my throttle mapping be this bad.... Here's a strong tell..... the the pedal pressure distribution. Sameh handed me drag-style maps with shit throttle mapping. The OTS tune, which we all know is garbage and non-linear, is a lot more...
