I'll be honest, I don't usually pay that much attention to the props / cats thing. But an average ratio of -6 cats per post means that this relationship just isn't working out between us.

Goodness what did I come back to? Lol
Sorry for lack of updates, been crunching to make a bunch of improvements before COTA. Many refinements rather than massive changes. More power will be something coming later this year when I'm not under the gun, but every time I'm out with the car I learn more about it and come home with a long list of tweaks to make. GTA Finals at Buttonwillow was no different, the car will be the same overall spec as it was then but lots of details improved, reinforced, etc.
It's making enough downforce to warp generally immovable things that the front loads transmit through, so have had to cut out and rebuild a few things.
Titanium skid pucks on the underside have increased in thickness.
Swapped the Wilwood 1" MC and early booster to a NB2 Sport booster and factory 15/16" MC.
Will be testing some new bumpstop solutions.
Acquired spare throttle body, gas pedal, and ECU in case there's ever a drive-by-wire issue.
New oil cooler config using the V8R engine plate, Setrab cooling, Staubli dry breaks... less pressure drop than old setup that was removed due to too much pressure loss.
Converted to manual steering via a custom idler pulley setup to eliminate the pump. Rack de-powered and welded.
Testing this weekend.

Mind me asking if you used HPTuners for your ECU? If so I'd love to get my hands on that e85 info. I plan to add in the e85 sensor as well while I am doing a few other things in the coming weeks. The sensor appears to be PN=13577379 but I can't seem to find the part number for the e85 sensor connector anywhere. I have a crap load of 3 pin connectors in my wiring tub so I'm hoping I will get lucky.....
Here's what I have in my parts list on this car:
Flex fuel sensor GM PN 13577394
Flex fuel sensor pigtail Ebay (no PN, just searched "GM flex fuel sensor pigtail" and found one with a picture that looked correct for the sensor I had)

Mostly because I lost two 1" MCs to date. One at Laguna Seca last fall, another at Buttonwillow on day 1. Then a third at a test day right after that, but the third one was my fault. Considered a manual setup, might still go that route but decided before I go bananas on it I ought to first try the simpler solution that the Stoptech calipers were designed to work with anyways. Coming from the old setup this is less piston diameter but more boost assist. We'll see if it amounts to much difference at the pedal.

If you like that setup and then decide you want a little less boost you can get the 15/16ths master but with a normal amount of boost from an MSM.
How long do your Ti sliders last? I ended up making mine from scraps of D2 tool steel I think these were like 60Rc which is close to the most wear resistant metal you're going to get for reasonable money. You can probably make them have way less surface area as your Ti ones for the same wear rate and end up being lighter and cheaper.

This is the 6.4:1 booster (NB2 Sport non-ABS and MSM).
First impressions driving around the lot, slightly longer pedal travel but less pedal pressure (no surprise). Pedal feels good once I'm through that longer initial travel. Miiight want to try a 929 MC as well, but going to test this weekend.
Hard to compare longevity without a bunch of other factors. Frequency of contact, surface area, etc. I just cut a couple dozen Ti sliders, so I'm going to be set for a long time.

Loaded up. Gridlife is doing their first ever West Coast track battle event at Streets of Willow tomorrow. We need to test before COTA, so timing is perfect. What's not perfect is the weather right now.. but the forecast claims it should be mostly clear tomorrow. Fingers crossed that we get some dry testing in.

GRIDLIFE came to the West coast for an exhibition of their Track Battle format. We had Hoosiers left over from UTCC last year just begging to get used so we entered in the unlimited class and got ready for the party.
It was a cold day out, low surface temp with little sunlight to bring the surface temp up and very little rubber on the ground after the storm the day before. Hard to get enough heat in the tires, they were about 40 degrees below optimal. Thankfully the weather held and it did stay dray through the day, and I was able to push to find as much speed as was available.

Lots of cool cars out at the event but at the top of the time sheets it turned into a battle for top honors between us and a fellow GTA competitor, Steven Chan in his 780 whp GTR on Hankook slicks.

The track got slower through the day with temperatures dropping and rising winds. With each session I cleaned up my lines a bit more and found areas to pick up time, but with every few degrees of temperature drop we saw the times inevitably rise several tenths. If the weather had gone the other way and warmed up we'd have been in the 1:16's and contending for the overall production car record.
Still, 1:17.0 landed 1st place in Unlimited, Top Time of Day, and a new Miata lap record by a big margin.
The car felt solid, coming home with several little notes for tweaks and things to check before COTA but overall we're ready to rock and roll.
