MoonshineV3 - GLTC Remote Mount Party Mode
#101
Depends on what you're looking for, if you want OE looking fitment I would steer clear. If you just want a tough piece that fits "good enough" and isn't an air dam for your track car, send it. I spent a decent amount of time working with it, shaving some areas, and so on, and it's still pretty meh fitment, but about what I expected. Perfectly fine for racecar.

Made some good progress on the racecar over the weekend. Finally hunkered down and "finished" the roof scoop. It's not perfect, but it's at least molded well enough this time that I can go back and put some time into it to clean it up, but for now its doing its job. The intercooler ducting is also gonna need some love at some point, but as-is is also in a working state so gotta move forward with other projects and circle back to stuff like that. Between waiting on resin to dry I also modified my wing mounts for the GLTC "free" wing I have, repositioned the rear-view camera, and re-installed the "GT3" side mirrors after drilling out the base so I can fully tighten them while installed. The camera was too close to my face and forced a huge re-focus of the eyes, which felt unnatural. Only issue with new poistion is I have to find a new home for AFR gauge. For the wing I'm not expecting any real downforce as it's a tiny 40" x 6" chrod foil, I'm just hoping it negates the lift of the fastback. Having driven the car with no wing at all it's doable, just a bit loose and full on PARTYMODE. Finally, once I got everything put together yesterday I took a Sunday drive down to the new Raceway fuel station and filled 'er up with pump e85 of unkown potency. I really need to get a flex fuel sensor for this life, but armed with my laptop made some manual adjustments in conjunction with VE Analyze. Haven't made any timing adjustments yet, but motor/turbo already diggin the corn juice.

Next projects will be undertray and radiator ducting, then get those KBD parts painted/wrapped for final install. After that hopefully start getting into some tidy up work such as fixing my fender vents (got new templates from Singular so I can do it right this time), brake pad swap (R12f / R10r to R16f / R12r), install brake ducting (BX11 ducts are already installed), and so on. This weekend generated some good momentum, just gotta keep after it because GRIDLIFE CMP is coming up quick. My Sprinter is also in limp home mode, so gotta sort out whatever is going on with that. That little 150hp turbo deisel is gonna have a bad enough time at 20lbs of boost pulling a miata around slowly, at 3lbs it ain't gonna get anywhere.
As far as the wing goes, I'm not doing it because I think it'll be good from a raw pace perspective, I'm just doing it because I've essentially accepted I'm not trying to be competitive in GLTC (or any other series) at this point. Don't have the time/money/patience to spend all my time on racecar stuff, so just building the car for pure enjoyment and I fully believe less aero is more fun than more aero. In this case I do get 3% back for a bit more power at least. Wings are fantastic devices for making a racecar faster, but being that locked down is kinda boring imo. Spicy takes only. Also, mid-pack back where I live I wanna try having a raw pwr/wt advantage. As the car sits in this trim I'm getting real close to have a net negative modifier, but at the very least I'm rigth at 0 mod%. There were plenty of times at COTA where even with no wing I was getting held up in the esses, which makes no sense. So, applying some iRacing logic here I'm going to try giving up a bit handling to have more passing/defending power.

No progress from Thursday-Monday because of an 11 hour road trip to a buddies wedding, but the good news is the van (2006 Sprinter, new adventure van/tow pig) didn't hit limp mode in the 22 hours of jamming out miles. Had a fuel pressure sensor go out on me so glad it was an easy fix *knocks on wood*.
Came home to a few new parts inlcuding DW700cc injectors to replace the 450s. Would have been a good opportunity to go ID's, but honeslty I wanted the ease of straight up plug n' play with only ~two weeks to next race weekend. Need to go get a proper tuning session in before CMP, but already getting the expected results of ~80%DC in logs verses nearly 120%DC and AFR's running away after 6k RPM. Smoothing out the fuel should be pretty easy task one night this week or weekend, but first I really need to turn n' burn on the most important bits remaining: Undertray, radiator ducting, and brake ducts (inlets/hoses). Either way, e85 + a few degress of timing bump is looking good so far.

Well, not everything is done the way I want it done, but we're ready to go rip at CMP. Livery and some other projects will have to wait, but got a good bit done this weekend including: undertray, radiator ducting, spring rate change, brake pad compound change (Gloc R16F / R12R), side skirts and most important washed it and the wheels (holy moly they were dirty). Still need to secure some stuff in the cabin, but mechanically it's ready for first session which is nice. Usually I'm grinding until it gets loaded up and I leave town haha. Also added a turbo blanket, which is cutting down on heat radiating off the turbo quite a bit. Figure that will be helpful now and in the future when i move turbo down to OE muffler location because I'm kinda tired of having it effectively in the cockpit with me.

Can't belive you went with a remote mount. Can't make any power on a miata with that!
Great thread, I just found it. If you've seen my build thread, you'll know I had one of the biggest turbo's ever put on a miata rear mounted years ago (but in a compound setup). It was a ebay GT45, T6, 1.05 AR. It did make power.
What worked for me was keeping the piping from the engine to the turbine very well insulated. That kept things hot and helped response a ton.
I also ran into issues with a restrictive intercooler at one point back when I was supercharged, so I recommend keeping an eye on the delta P across it.
My new setup doesn't have an intercooler, but I will likely add a small one beside my radiator in the near future to knock some of the heat off That should help get a bit more top end out of my turbo as it's too small for what I'm doing and will be at choked flow at higher RPMs.
Earlier advice about keeping the TIP down is great advice. I did this on my setup, as the GT45 was very lower restriction. I experimented with each turbo operating at diff pressure ratios. The small turbo spoolign gave great resonse. But if you let the big turbo carry a lot of the load, the car would just pull like hell to 9K. But response was very poor.
My advice, if you're going to stay rear mount, get a good turbo and insulate the hotside, every inch of it.

Definitely interesting in measure delta P and TIP, too, just constantly in a state of procrastinating on all the necessary stuff and not leaving myself with time to do the fun stuff.

Welp, all in all had an incredible weekend at CMP. Car ran perfect all weekend, just did some setup work getting brake bias and chassis balance/damping mostly dialed in. Day 1 we had uhhh, WAY too much power. Race 1 I was motoring everyone like a typical Mustang bro in DE that won't give point bys so threw myself on the dyno and booooooy she was spicy. Of a claimed 190whp I was making 225-227 at 10psi tapering to 8.5, so did Bama math and turned the boost down as much as I could resulting in ~7psi tapering to 6. I also self DQ'd and started from the back of race 2. Can't seem to make any less than 6 on a 4.3lbs spring, but will do some more playing with it now that I'm home to see what I can do and then get a tuning session scheduled at local dyno. Coolant temps werea perfect 185f in every session with not a hint of creeping higher, i.e. I need to play with reclaiming some drag by blocking off the rad opening/hood vents, but IATs were still as high as 155. The IC/e85 took some edge off, enough to not pull timing, but still up there. Running safe AFRs (11.8ish) and non-bleeding edge timing I just hoped that wasn't detonating and sent it. I'm probably wrong and will be building a motor before long.

Thanks for sharing. That looks like a friggin HOOT! The power delivery and sound reminds me of a rotrex. Flat out through that sweeper (corner 7?) looks fun/scary.
You and the car were hanging in the pack there well, some mean chassis to have to fight against in that class.

And yeah, power to weight really helps even things out. I have a lot of development to do on myself and the car, but this weekend gave me a lot of hope things can actually get much better.

No updates, just a picture. Can't wait to finish up the livery and get this thing looking poper *everyone collectively rolls their eyes*
Probably going to run NASA NOLA in about a month and setting up a list of test sceanarios starting with testing the car as it sat at CMP, then add tire spats front/rear - block off brake ducts/some of radiator - etc, re-spring, "free" wing vs "free" spoiler and so on. Also already signed up for GLTC Mid-Ohio, let's gooooo.

Working on fixing my fender vents. Got some fresh templates from Ryan, taking the incorrect bends out of the fins, and then doing it right. Did driver side last night and the fins are still solidyly attached, but definitely don't want to do any more bending them back and forth at this point. Not going to fully re-install until I re-do livery and installing them correctly from underneath need to do a little cleanup of my cuts because I'm a heathen. Anyways, more pictures.
