Pretty stoked about everything but the stupid start failure. I mean seriously, who's ever even heard of that being a thing?
The win for me is the SSB uprights and control arms getting pushed on Pikes Peak and working great. Hard to be the only person getting miles and events on some of these proto parts but Carl and team seem to have a huge amount of motivation to get the car faster and to events to push it.

Just read the whole thread, damn you guys really went all out with this car! Mine isn't even close to being this crazy but I'm hoping to try out hillclimbs next year or the year after. Kind of hard being in the midwest and it being so flat haha.
I'd also be curious to see what the car weighs in at. I'm at 2800lbs and change right now with a fully gutted interior, trimmed doors, lexan windows. If I could get weight under 2700lbs retaining factory sheet metal and gas tank that'd be ideal.
Also if I may make a recommendation. Earlier in the thread I saw you're still using the stock shifter assembly. I recently got a CAE shifter and it's night and day better than the stock shifter. It puts the knob closer to the steering wheel while keeping throws fairly short and it's extremely crisp. I don't want to come off like a sales pitch or anything, it's kinda pricey but I wouldn't hesitate to buy it again.

about the crack .... some dummy (me) left the hood unlatched at pikes coming down from a practice session and it flew up and cracked the windshield. we didnt ask and they never mentioned it.

Right now it has a full sized battery, 4 gallon water spray system, a stand alone fire extinguisher and a separate fire suppression system, an extra cooling fan etc .... from pikes so its on the heavier side.
replied to your PM. it was a blur the months leading up to pikes so my forum time was limited.

we had an opportunity to sell our wing so we picked up a swan neck.
Made a few options for mounts out of scrap galv.
This is the one bryant and phouvanh liked the best:
revised overall shape and tweaked geometry:
ran it through FEA and found a couple overly robust points and a couple stress risers. thinned the top up and tweaked the neck part to lower the von Mises:
ended up with a 2.2 FOS at 800lbs vertical loading. may downforce is 1650lbs at 160mph. i would image the highest loads we'd ever see would be 1000lbs.

got the car down to UMC (formerly Miller Motorsports). we were excited to get a chance to tune the cars handling in as there is not a lot of opportunity for that at hillclimbs.
since we are both new to the UMC/NASA scene we had to spend a few days getting checked out of the various HDPE classes and finally got bumped to TT. next month we will be able to get a timer on the car and get some quantifiable data.
bryant heading out on track:
after a long day of driving we gave it a once-over. between both drivers the car had 140 minutes of on-track time and went through over 30 gallons of e85.
here is some feedback on the car setup:
TRE drivetrain - working flawlessly. 500HP and doesnt skip a beat. Rear end helps the car rotate. shifts are smooth!
Fortune Auto Dreadnaught pro 2-way - this setup has been great. Being our 2nd set we they came dialed in from FA. we went to a slightly softer spring rate given the new valving adjustment range. On the bumpy hills we can soften the car up to make it more forgiving - then we come to fairly smooth track like UMC and we can stiffen it up for flatter cornering.
SSB Front end (dallas) - we've had these for the whole season. at the hills they've been handling well but i've been trying to get my head around how to optimize them. Dallas has always said to run less bar upfront - more rear bar / stiffen the rear end. As im sure i've mentioned before we like to run a slightly tight setup for the hills as a safety measure. finally having track time we really focused on making the car more neutral. over the course of 7-8 sessions we kept running more and more rear bar. then more rear compression. finally softened the front a bit and it kept getting better and better. In the past we have ran -4.5 to -5 deg camber in the front in an attempt to save the outer edges of the front tires. Per Dallas's advise we dropped to -3 (ish). while we has a slight amount of wear on the outer edge it is AMAZING how much more evenly they are wearing ... with less camber.

Awesome! Glad you tried dropping the front bar and increasing that rear bias. Its hard to say with the aero you guys have but sounds like you're feeling the same things I have.
Loving the amount of track and hill time you guys are getting this year. How are your brakes holding up to the track duties? We havent notched your uprights for ducting yet have we?
