I'm looking for a good carbon fiber helmet with a duckbill and coms (ideally built in, or easily added) for use in my Revolution A-One.

Right now I have a Black Armor from 2015 and it's not bad but my coms system connector broke (Race Radios stuck something into the helmet during a WRL race) and before I invest in putting a new coms system into my old helmet I figure I'd check to see if folks have some ideas. Right now it appears that Black Armor might not be in business any more...

Thanks!

Whats worked for you?

I track an R53 with LSD and was wondering if an equally weighted/powered open diffed RWD will be better. Of course there are too many variables. Nonetheless, interesting to see what different people think.

2) All attempts I make to form a team to build a car fall apart when the people who say they want to join realize I'm not going to fund the ENTIRE thing as well as do ALL of the work and just let them play with the race car.

So are there tracks near me or in an area worth moving to that doesn't have an insanely high cost of living? (Bonus points for warmer climates/short winters) And how feasible is it to get into racing if I have to fund and build the car entirely on my own while working 60 hours a week, because all I can find are free loaders?

The following goals are a bit of stretch but just to throw something out there, here goes:

1. At least 2 days of coaching
2. 3rd place or better for Texas TT3 Regional Championship
3. Podium at Nationals OR sub 2:00 at WGI - I will only be able to do 1 of these events this year
4. 1:17 at MSR-C
5. 1:59 at ECR
6. 1:33 at Barber
7. 2:24 at COTA
8. 1:19 at Hallett

Last Years Goals

1. Get 4 days of coaching - Got 2 days in
2. Break 2:00 at WGI - Never made it up there due to COVID
3. Break 1:33 at Road Atlanta - Did get a 1:32 
4. Break TT3 track record at Mid Ohio - Never made it back
5. Podium in NASA Mid Atlantic Region - Only drove 1 weekend

I'd pawn my grandfather's wheelchair if it meant getting some RA1's.

A few years ago i thought I was going to start instructing, and at the time was very unimpressed with the intercom offerings on the market. It seemed like everybody hates Chatterboxes. At the time Trac-Com came out with a competing product, but I wasn't that impressed with that system either and sold it before ever using it. 

I'm now actually signed up to become an instructor and need to find a suitable intercom system that doesn't suck. Unfortunately it doesn't seem like there has been much improvement in offerings on the market. 

Does anyone have any suggestions on what system to use?

Does anyone have hands-on experience with the Stilo WRC03 or the Speedcom SCC-2MPI relative to the Chatterbox/TracCom systems? 

Any help would be greatly appreciated!

Should I spend the money on corner balancing?

Benefit is more weekend time with my 11-yr-old twins enjoying car stuff like this shop-show down in Houston today. We still have fun on country roads in our '85 911 and '05 330i. Miss TWS, but happy for a shared hobby with my kids. 

So what does the DL 2 bring to the table?

Wi-Fi:

First thing that peaks my interest is WiFi. Could this be used to download data during an enduro pitstop? Is that enough time? Is AiM’s Wi-Fi robust enough to connect quickly and gather that data?

RPM Pick-Up/Shift Light Option:

Not quit sure how this works, but there appears to be an option for grabbing RPM for non-CAN cars, which is everything I race or track. Along with a good RPM the DL 2!allows for programmable shift light. More feedback to help pilot a car is usually a good thing.

Better Accuracy:

Aim markets the new Solo 2’s has have much improved accuracy with help from another collection of satellites or something. Is this just fancy marketing hype?

Finally can you emulate an OBD or CANBUS to somehow rig up a car that you could simply plug in a DL 2 and log you own custom sensors via you own emulated OBD or CANBUS?

SCCA racer Brad Gross enters COTA Trucks for CMI, NASCAR debut
https://www.thecheckeredflag.co.uk/2021/04/scca-racer-brad-gross-enters-cota-trucks-for-cmi-nascar-debut/

Stay tuned for more details, livery reveal, etc...thank you for your support / trash talking!! LOL!!!

• Accelerometer calibration can be problematic, and on more than one occasion I've come home with garbage data (only really a problem for the videos though)
• Update rate is not great for GPS (1Hz using internal phone GPS)
• No success whatsoever with integrating ODBII data - I've tried a couple different adapters and done lots of troubleshooting, but the data rate is always horrible to the point of being unusable

I'd specifically like to improve overall data rate and specifically start getting good OBDII data - I really want to be able to see throttle inputs and such, both to make nice-looking videos and to analyze for personal improvement.

The most obvious option, I think, is to get something like an AiM Solo DL. I'm not especially familiar with all the options, but I gather that the Solo is the budget option at $700. That's expensive enough to not be an impulse purchase, and to be honest I'd want to either try one myself or at least get lots of other people's experiences before pulling the trigger.

Another option would be to keep using HLT but with some better peripherals. I see a couple options for a standalone GPS receiver that will get 10Hz, which would be a marked improvement. The big question would be whether I could resolve the OBDII data rate issue; I'm not sure exactly where the problem is, if it's the adapters I used, or what the car natively sends, or it's an HLT thing, etc. So I'm slightly hesitant to go buy yet another adapter in the hopes that it'll be the magic bullet.

An interesting tidbit on the data point is this: I have the JB4 piggyback tune on my car, with a bluetooth module. I can pair my phone to the JB4 to change settings, read/clear codes, and...read realtime data. From this, I know that it's possible to get high-rate data on throttle position and so forth, because it works great in that app. The major difference there, of course, is that I'm getting data from the CAN bus instead of through the OBDII port. I lack the technical knowledge to know if there's any practical or expected difference between those two.

Overall, I'm leaning towards a Solo - maybe keeping an eye out for a used one now that the Solo2 is out - because I feel like there are far less questions with that option. Plus it seems a lot simpler - one box to set up for the weekend vs. phone + GPS + maybe wired OBDII adapter...but HLT + addons would certainly come in cheaper.

Thoughts?

Location:

Sonoma Raceway. Course was prepped behind main grand stands. There was an on-track event happening at the same time organized by the same club/org, so the main paddock area was used by "the big boys" paying for track time.

Format:

First off, this was a non-competitive event. Field of about 60 drivers at the beginning of the day, split into two groups. We did two sessions A group drives, B Group works then B Group drives, A group works before lunch. After lunch, we did 4 more sessions, ending the day at 5:10pm. The day started of course with a driver's meeting discussing safety, expectations, safety, cone working, safety, format, and safety. After the safety was safetied we did a course walk and discussed the "safe" line (Sonoma doesn't allow instructing, no talk of "fast" lines!). There was also a second driver's meeting after lunch which I missed as I lost track of time fixing something on my car (more on that later). The groups were staged parked in two rows at an angle. One line would pull out bit by bit, staging for their run, and once through the next side would start lining up. Nobody was counting runs, just keeping the cars rolling as often as safe/possible. Though this wasn't a competitive event, they had timing equipment on hand so you could catch your time as you slowed down after the finish line. Super helpful/awesome.

What I brought:

I roped a friend with quite a bit more track experience (mostly drift, some Lemons, etc) to be my wing man, and also hold me accountable to make sure I actually attended and didn't pull my motor out for an excuse to not go. So we'd talked ahead of time to make sure we didn't double up too badly on supplies/tools and did our best to support each other. That said, I made a spreadsheet (google docs ftw) so I could track what I needed to pack still, and also for future reference to reflect on. Here's the list:

Hat
Helmet Sock
Tire Pressure Gauge
Chalk
Folding Chair
Water Bottle
Sun Block
Timing Light
Paper Towels
Nitrile Gloves
Ear Plugs
Tape
Cardboard
Laptop
Laptop Charger
Power Inverter
Multimeter
Test Light
Long Flat Screwdriver
Short Flat Screwdriver
Long Philips Screwdriver
Short Philips Screwdriver
3/8 Ratchet
3/8 Socket Set
3/8 Extensions
Zip Ties
10mm Wrench
12mm Wrench
13mm Wrench
14mm Wrench
17mm Wrench
Crecent Wrench

That's obviously just my main column, with other columns for quantity, item details, URL if relevent, etc.

You'll notice Helmet isn't on this list. That's because my buddy had one he was gifting to me (friends are great!). It was his old one, mildly worn, with a Snell 2010 certification, so hopefully it's still good for a few seasons.

It also helps to have a friend who races regularly to give you tips (hat tip to Jesse over at DrivenDaily in New Hampshire). He shot me over his packing list, and while far more extensive he helped note some key items and some basic guidance on what to expect. He was the one to tell me to bring chalk and brought up side wall marking.

Results:

I was about to get somewhere between 15-20 runs in for the day, which was fantastic. I started my first run just putting around, making sure not to get lost and loafed out a 47 second lap. Feeling a bit more confident I wouldn't get lost, I adding some power the next go around, and ran a 38.something. I then ran a 37, and was notified I missed a gate. Woops. Pay attention! I didn't have an issue getting lost again throughout the day, and took a couple runs to get down into the 33/34 second range, where I sat most of the day. I did manage a 32.064 which I was thrilled about, though my friend was running solid 30/31's all day, so I was still a good bit behind that. Towards the end of the day I got some tips from ride alongs, and was able to see another 2 seconds out there. But I ran out of time to put it all together. That's probably the most frustrating part of the day, to feel like I needed just a few more runs, but the day was over. Working the track was great fun too though, as I was able to see a huge variety of vehicles as well as skill levels involved. From Tesla 3's creaming most of us, to an old 67 Camaro with probably six figures into it that was nothing to laugh at and put down solid times all day. Then on the other end there's a girl attending with her boyfriend, him in a SN95 and her in an 80's nissan hardbody. It was her first event, and I felt like cheering her on every run as I saw her times start at 50+ seconds and whittle their way down to a 38 (and honestly, it was a truck with a mild lift running 28"+ tall wheels, I'm not sure I'd have been any faster in it). It was also healthy to see/watch newer muscle cars span the distance from 28 seconds to 35 seconds, showing just how much of it is driver and confidence in the vehicle. All in all I felt great about my personal results, and while definitely found plenty of aspects to work on, was also encouraged that I'm not incapable of driving decently.

The Vehicle:

It's at this point I get to start making excuses. So get ready. The vehicle is a '75 280Z. It last weighed in on truck scales at 2280. Tank was probably at about 1/4 at that time. The engine is a L28ET running megasquirt (all built an tuned by me). According to my virtual dyno (which feel free to take with a grain of salt, but I can also give you all my data to back up my known degrees of accuracy) makes about 180 peak HP at about 6,000 but is also making 150hp at 4,300 and carries 160hp to 6500. So it's a nice fat HP curve. The big issue, is the tires. They're "what I've had" sitting on my shelf for.... 9 years? They're Sumitomo HTR 200 (205/60R14). It's a 380TW tire, so not the hardest tire in the world, but it's age probably isn't helping. It's also definitely an all season tire, with deep water shedding grooves. And of course they haven't been heat cycled or the like. I know I'd have ran faster times with better tires, but like I stated earlier, I could see piles of time left out on the track. I plan on buying some commuter tires soon, and will be buying 15" wheels with some "fun" tires to wear to the track next spring.

What I learned:

I need to be more aggressive with the throttle. My idea of "at the edge" apparently isn't at the edge enough. Because I'm still feeling traction limited all the time, I wasn't dipping to 1st in places I should have been. My digital gauge/dash was on the fritz, which made me less weary about pushing the RPM's in first without any form of a shift light, and looking through logs, I rarely reached 5k and even then that was only in 2nd. First was only ever reaching 4,200, so I definitely let piles of room on the table considering I can run to 6800 all day. I also didn't feel like I really had enough time to play with tire pressures with this format. There was hardly enough time to run back to my parking space 200 feet away to grab the tire pressure, let alone check all my tires. By the time I grabbed the chalk and was marking my tires and seeing the results, I realized I could have dropped a lot of air but wasn't sure it even mattered with how much time was being left out there due to me, not the tires. Another big lesson learned, was that my car didn't break. That was the big goal of the day, but it was nice to REALLY thrash on the car and find it holding up. When something has been in the garage for this long, it's hard to feel like you've REALLY checked every bolt... Also, it was 90+ degrees out there, in the shade. I couldn't have brought too much water. I kept refilling from faucets at the track, which was okay, but I wish I'd brought more. It also took me too long in the day to lose my propriety and just dunk my hat and shirt in the sink and wear wet clothing. Once I did that I realized I'd been quite dumb/silly all day. I was much happier being cooler and wet (fun note, we don't have considerable humidity here like most of Texas, so getting wet will quickly drop your skin temps what feels like 10+ degrees since the water evaporates so quickly). Another little driver less-learned was that I need to be willing to chew more wheel with my outside hand when it can prevent a shuffle and allow smoother steering. One main low speed turn kept me puzzled most of the day as I felt I couldn't get my wheel moved fast enough to exit where I wanted. I don't want to think about what stick 225 or 245 tires in the front will be like turning, but I can see that I definitely need to become more economic with my movements if I want to have any arms left at the end of another day like this. Some other lessons learned: A basket somewhere would be a handy, as I need a place to keep things like chalk and the tire pressure gauge IN the car, so I'm not running around grabbing those every-run items. My helmet hits the roof, which means when I get a kirkey or similar seat I'll need to drop my seating position about 3" if I want to pray to be SCCA legal post-cage. This might put my visibility much lower than I'm used to/comfortable with, and will likely run extra padding on the street for this reason. My friend used milk crates for his supplies. I used cardboard boxes (and a backpack)... I was jelly. I need to get better boxes for the stuff/items. An unreliable dash won't ruin your day, but it's quite annoying. Need to solve ECU to Phone communication drop outs.

What I'll do different:

Go to more events. This was $75, and probably the most fun I've had under $100 in a loooong time. It was a great way to spend a day. I should do it more. I also should try to  ride-along more. Several strangers asked if they could join in, and it was great to get other people's feedback, but there is no reason I couldn't have been taking notes on their driving. I also need to be better prepped from a toolbox perspective. I could use something like a metal tackle box for most of what I need for events like this, and could/should probably just spend the money to duplicate the base essentials.

What when wrong:

Since I mentioned working on the car. I'd been having some standing idle temp control issues with the car, and I thought that maybe my head temp sensor was sitting way above the coolant temp sensor, so I'd pulled the plug I had, and moved the sensor, Well, when I put the plug back I didn't apply more sealant, and of course it leaked. Over lunch we managed to get the plug reinstalled with a couple wraps of electrical tape, and that stopped the slow drip. In fact, now that I think about it, that tape is still on there.... I should fix that....

Anyway, some videos for fun. I don't have any of my car because of a strict hard mount only rule for cameras (safety first!). So here's my friend in his 280ZX:

And this was the fastest car I witnessed in the B group (26 second range) while I worked the course. You never know what vehicle will be fast ( a good lesson learned ) but talking to him later this guy was obviously a track rat.

Enjoy! Hope you like the book I wrote for yall.
