Evaporative cooler sling for outings ? Ice pack in sling?

Did you go enjoy races ?

I think due to my lack of sleep, I completely forgot about it until you just posted this... I've been pretty much in a daze for the last week. I sleep in 1-2 hour chunks then lay in bed or in the chair for an hour or two trying to get comfortable enough to sleep.

We had some friends over Sunday for Memorial day, which was nice. We put the truck on the lift and tried to troubleshoot the air leak, the new check valves were not working at all, but we did find another small leak as well.

I have a Breg Polar Care Cube that I use with the shoulder wrap to ice my shoulder. You fill it with ice and water and it pumps it around the pad like a cool shirt.
 
Body needs to heal. You'll rest up. Use the pain meds no need tobtuff it out.
 
I hate opioids/opiates. They barely do anything for me other than make me want more. The pain isn't bad during the day, but getting comfortable at night has required me to take them to get to sleep. I was feeling better yesterday, so I didn't take any last night. I was up for 3-4 hours before my brain calmed down enough to go back to sleep. I won't be taking anymore.
 
Not gonna sugar coat it….its a long healing process, but necessary for long term success. Keep the sling on, its a reminder to not use the shoulder/arm while it heals up. Do they have the “moon” PT procedures in your upcoming PT rehab routine?
I just started my strenthening and resistance portion (@18 weeks) I feel I should make a complete recovery. I know some people try to be the “tough guy” and start using the shoulder/arm too soon, and then have recurring pain because of it. Don’t be that guy!
Even though I know I have months to go for full strength, I feel right now like the shoulder is more comfortable than before surgery. I see the surgeon for my 5 month visit in 2 weeks. Hopefully no more restrictions after that. Ive been cautiously using my arm more normally now, but have to remind myself not to do anything stupid and set myself back….so far so good!
Good luck and try to stick to the plan. In the long run you’ll be glad you did.

I understand and have definitely been keeping my arm in the sling most of the time. Right now I'm sitting at my computer with it out while I ice it, but the surgeon said that was fine. I have to do that occasionally or my elbow get's extremely sore from lack of movement.
I would say I'm in more pain now still than before the surgery, but it's not bad at all. My first appointment with the surgeon is tomorrow and I think he's going to have me start using the shoulder pulley after that to start stretching out my shoulder. PT starts after 4 weeks.
 
Friday night was fun, we chatted with some of the staff that recognized us and ended up sitting in the nice air conditioned VIP area at the bottom of the tower. They felt bad for me because I couldn't race I guess?

Saturday I pointed at things and my wife pulled our air system apart. We found and fixed the leak, we had some corrosion around an o-ring that was causing the leak. I need to drain the condensate out of the air tank more frequently (I've never done it in the year since I installed it). It's re-sealed for now though, no more leaks.
 
Our local drag strip has started midnight drags for the summer. I was feeling like I could manage to do the 2-3 shift and turn the brake shutoff valve with my right hand for the burnout/staging, so we attempted to get the truck ready for that yesterday. I had a leak in the new nitrous line that I had to address, and I wanted to move some of the sensors around (bottle heater switch and pressure sensor) as well. We got the truck on the lift and Amber made, modified and installed the new hoses. Unfortunately, everything leaked...
We used Fragola Real Street reusable fittings along with their 6000 series PTFE -6 hose. I've built a ton of this style hose using Parker, Evil Energy and Fragola parts. This one is rated for 2500psi working pressure as well as nitrous oxide, but every single hose end was leaking. We went back and looked through their website, watched videos on assembly and I have no idea why they are leaking...
We were only planning on doing a 100 shot, but this truck is so lazy off the line it really needs it right away just to get moving.
The list of failed parts continues. Speaking of that, Motion couldn't replicate the issue I was having with the MAP sensor, but they did send me a brand new one and recommended I remote mounted it rather than putting it directly in the intake manifold. We took care of that yesterday and drove the truck to a local C10 event with no issues even though it was 111°F out when we left.
I was thinking with the 100 shot we should be quicker and faster than the old setup, I was hoping to see a 12.5 or better at 110+. The next one is about the same time in July, but it will be even hotter then.
 
Man I too have built a ton of PTFE hose, but all mainly aeroquip. If I had every hose end leaking I'd be talking to someone. Has to be a mismatch between the ptfe ID and the ferrule, or the taper. I don't think I've had a ptfe hose end leak in like 10 years, I can't even remember the last leak it's been that long.

If it was just one leaking, I had a couple extra olive ferrules and would have rebuilt it, unfortunately the ones I could see were all leaking between the nut and the fitting. I double checked that we were using the correct ends with the hose. I would bet it would hold up to 100-200psi fuel pressure no problem, but the 900psi nitrous wasn't having it. Once it starts to leak things get real cold quick and it leaks worse.
I went with the Fragola because they are the only ones that sold a DIY hose with a black sheath that could handle nitrous pressures. We're going to take measurements today and just order their pre-made crimped lines. I'll probably send an e-mail to them as well to see if I can at least get them to send me some new ferrules so it's not all junk. They would probably work fine for fuel or power steering.
 
I talked to the guy at Induction Solutions (where I bought the nitrous plate), he said he's never been able to get the reusable fittings to seal with nitrous. I ordered all pre-crimped lines and we'll get it all set up for next month's run.
 
I still can't talk myself into nitrous for my truck,....
But it sounds SO FUN. lol.

Interesting. Good job on calling man! Knowledge is knowledge.
 
Time for a new update!
We got the new nitrous lines last week and got them installed and pressure tested. I worked on the tune a bit from the info I got from Induction Solutions and we went to the Drift and Drag event at Firebird on Saturday night. The gates opened at 5,PM but we waited until 8PM to at least let the sun go down. There were so few cars drag racing it was like having a private track rental. I ran 3 times and there was only one of the 3 where I didn't drive straight into the burnout box and that was because there was an oil down on the track.
We put jets in for an ~100hp shot using PWM to bring it on over 1/2 second (just to verify how it worked).

First Run:

I was rusty and forgot to turn the rear brakes back on before I pulled up to the starting line so it spun just before the light went green and I had a slow start.
Second Run:

Third run:

It was very consistent so I didn't bother wasting any more Nitrous.

Based on fuel usage (2hp per 1lb/hr) I was only making ~600hp peak with the nitrous. I'm working on getting it to a tuner to get my gasoline and e85 timing curves dialed in, that should get me the 100hp I'm missing.

Because I went from 4.10:1 to 3.73:1 AND from 275/40R17 (25.7") to 28x10R17 I slowed the driveshaft down by about 17%. Pair that with the big cam, it's pretty lazy off the line still, needs more nitrous! It was over a second faster than when I ran with the old BTR nitrous cam N/A though, so we're improving.

I won't take it back to the track until I get it tuned, then I'll probably run it with the same jets once to see the improvement, then start bumping it up until I get close to 11.5 or 135 (NHRA cage rules).

It felt good to go down the track again, even though it was 100+ out.
 
Are you planning on a cage? I’m assuming you are going to be doing it yourself.

Glad to see you and the truck back out!
 
I don't really want to do a cage as I think it will cut down on the usability of the truck. NHRA rules say I can only go 11.5@135 without a cage, but other promotors say I can do 10s. PowerTour says I only need a helmet and can go up to a 10.0 and I think a lot of the drag and drive events use the same rules.
I'm fine with 11.5, but I'd love to see a 10.something at least once while this engine is in the truck.

The truck is going to UMS tuning next Tuesday. They have a nice hub dyno and do load tuning at 500rpm increments as well as WOT tuning. They're going to do the whole process twice for me, once with 91 and once with E85.

The plan is to just see how we like doing the drag and drive events with this truck, then this engine will go into a more appropriate dedicated drag and drive vehicle. We're currently debating between using the Sonoma I already have (Cream Puff XL?) or picking up a Chevy 2/Nova Wagon (Amber's choice). Either option will have a full race chassis that I'll put together. Both platforms have tons of support, although it would be cheaper and easier in the S-10.
