NSXPO Recap - Day 1: The Drive
With NSXPO registration set for around 4-5 pm Central Time in the hotel lobby, I calculated that I would need to leave home at roughly 3:00 am Mountain. Thus, I packed the car the night before and grabbed about five hours of sleep before I set off. Here's the route:
I was deeply concerned about the weather, since it was the end of October and in Colorado all the way to the New Mexico border, that means potentially a massive snow storm at any time. Same for the plains. While my Conti ECS tires do great in the cold and in the wet, they are summer tires. A freak snow squall could mean the total loss of the car. Thus, instead of running East through Kansas on the nice open interstate, I chose to run South toward the warm weather. This meant taking US-87 Southeast through Amarillo.
Night Drive: Denver to Raton Pass, NM
I departed on time and the car warmed up quickly. I can report that the Hikari "Vision Plus" LED headlights are a fantastic upgrade. Even just the low beams provided an enormous field of view and I felt like I had very good night visibility. I used the brights frequently and it was like a WWII searchlight. You may recall from my other posts that the "Vision Plus" series of lights uses a single, domed Cree XHP50.2 LED unit instead of a matrix of smaller LEDs. I find that it creates a more even light beam without any weird artifacts in the pattern. I was very pleased during the pitch black rural sections of I-25 and felt safe.
Given the darkness and absence of other cars, my main concern on this leg of the drive was wildlife. It's fall and the deer/elk are out in force. As such, I kept to or below the speed limit of 75 to help give myself reaction time if something jumped out across the road. The only creature I saw was a huge 10-point whitetail buck just off the shoulder eating some grass outside of Pueblo. The Hikaris spotlighted him well ahead and he just looked up at me as I drove by. Still, I brought the car down to 55 just in case he spooked and jumped out onto the road.
I crossed the Raton Pass (7,834 ft / 2,388 m)in the dark. It was the only weather danger on this route, as rain at the bottom can be snow at the top of the pass. Thankfully I had clear, starry skies.
Sunrise Blast: Raton, NM to Dalhart, TX
Making the left turn from I-25 to US-87 in Raton, the sun started to come up and visibility improved. Within an hour it was daylight and I had wide open, straight roads with miles of visibility. With little to no other cars around, it was now safe to explore the potential of my engine design choices. Here's what I found. I did not have the chance to calibrate my speedometer, since after the capacitor replacement service from BrianK, it started to drift over 70 mph.
@NSX_n00b has the calibrator and I haven't had time to make it down there. My Uniden R3 radar detector has GPS, however, and I used it to get an accurate speed. Interestingly, the NSX-R final drive allowed me to "drive the tach" for the most part. 80 mph = 3,500 rpm; 90 mph = 4,000 rpm; 100 mph = 4,500 rpm; and 110 mph = 5,000 rpm. Once over about 90, you really start to feel the aero working on the car. The NSX just starts to suck down to the road- it got more stable the faster I went. A cool effect is that I could hear a steady hiss of air being sucked into the engine compartment through the cowl vent via the low pressure void under the car as speed increased. It really does work as designed in the wind tunnel.
Running at 5,000+ rpm though New Mexico, this is the picture I had constantly in my mind:
I was the one who clearanced the gears and shafts. I was the one who assembled the stacks. And, I was the one who torqued everything down. Did I miss something? Did I make a mistake? Would my trans grenade itself under the strain of a constant 120+ mph? After about 100 miles, I started to calm down and trust my work. The transmission was as smooth as glass. This journey was confirming that I had indeed done my job right. A quick fuel stop in Clayton, NM and I was streaking down to Texas.
Crossing into Texas, the party was over. The road turned to trash. I don't know what Texas DOT does for paving, but the road surface was like a crumble of compressed gravel on top of the asphalt. It wasn't loose, but it was uneven and LOUD. Plus, upon entering Texas, I encountered a steady stream of trash trailers that were running without mud flaps. Every few miles or so, they would rip up a chunk of this rough road patch and throw it in the air towards my NSX. I slowed way down and gave them plenty of room.
Then I got to Dalhart and discovered the source of the rough road surface. They were laying down what I can only describe as road gravel soaked in hot, liquid black tar. These knuckleheads were just dumping it on the road and letting traffic drive over it. Maybe that's how they "paved" it? I slowed to about 20 mph in 1st gear. As I listened to the gravel pinging all over my undercarriage like a low-speed sand blaster, I could only think of all those hours I spent scrubbing the car during the refresh. It was 4 miles of misery.
Entering Civilization: Dalhart, TX to Ft. Worth.
I finally escaped the Mad Max-like devastation of Dalhart and made it to Amarillo for lunch and gas. Pulling into the McDonalds (it's my go-to "GI safe" travel food), I inspected the car. My windshield was chipped in about 6 places, thanks to the trash trailers. Also, there were two big chips in my right rear wheel. Again, trash trailers. Plus, the skirts of the car were covered in liquid black tar the consistency of water. Not good. Thankfully, I had had the good sense to have all of the underskirt areas covered in PPF. Hopefully it would wash off. Leaving Amarillo, I picked up US-287 and things opened back up for a while. I was able to make some good time.
The run between Amarillo and Witchita Falls was very much like interstate, but with stops in each small farming town along the way. I was very careful to obey the speed limits there- it always went from 75 mph to 65 --> 45 --> 35 and then in the reverse order leaving town. I didn't find it disruptive at all. It gave the transmission a chance to cool down. However, as I got closer to DFW, the number of cars on the road got steadily higher. Eventually I was just cruising in traffic at 75 mph.
At my Valero fuel stop in Witchita Falls, a nice older African-American gentleman walked up to me and told me he'd been running with me since Amarillo, pointed at the NSX and said "man, that thing can really MOVE!" He was catching up to me in the towns and then lost me as I blasted away from them. He had never seen a NSX before, so we had a nice chat about the car.
By the time I entered the DFW exurbs, it was a hot 90F outside and the A/C was blasting. Again, I was grateful all the A/C struggles got solved last season. I soon found myself in DFW rush hour traffic, creeping along in 1st gear. Finally, at about 4:00 pm, I rolled into the DFW Hilton Lakes host hotel and was greeted with a sea of NSXs. I made it.
Thoughts:
- My distance covered was 761 miles.
- I made the journey in 12.5 hours. Google says the drive would take about 12 hours straight through. I spent about an hour at gas stops and food. Leaving the house at 3 am MT and arriving at 4:00 pm CT, subtracting an hour for the time change and an hour for stops gives us 11 hours drive time. DFW rush hour really hurt me and it took almost an hour to get to the hotel once I hit the city limits. But for that, I would have been closer to 10 hours.
- I thought I would miss the cruise control, but I didn't. I found that my foot got fairly steady after an hour or two on the highway.
- The NSX is very easy to drive fast. The aero and the suspension work to make the car comfortable at speed. I found both hands moving to the "10 and 2" racing position as speed increased.
- PPF is a must on this car for long distance travel. My paint would have been ruined.
- Same for the windshield. I'm looking into the ExoShield product. The White NC1 parked next to me had it and I was impressed.
- The NSX-R differential is....a lot. I found myself missing the 6-speed.
- The powertrain performed flawlessly. I did my job right.
- The tune was perfect at all altitudes and never even hiccupped once.
- My Uniden R3 caught 11 speed traps between Raton and Witchita Falls. I had on average 2-3 miles of warning. They were all running Ka band Stalker guns.
- Waze caught 3 "hidden" speed traps where they were radar silent and shooting laser from behind trees.
- The Conti ECS are great tires.
- The radiator guard was clutch- the whole front of the car was bug smashed, and all the debris from the trash trailers likely would have holed the rad core. Thanks @RYU!
- I would not drive this way to Dallas again in a NSX because Dalhart, TX. That road...
