Couldn’t sleep this morning

I kept getting woke up by noises and pains. And the odd twinge and muscle spasm.

At least now I’m not bothered by engineering problems I can’t solve without access to a computer for parts information and a calculator for other problems. As in there are multiple OD ratios available for that T5 gearset upgrade and one I think might be too tall for the Sprint-T. That would be the 0.59 ratio that comes standard with the upgraded gearset. With the difference in diameter between the race tires 23″ and the street tires 27″ is like throwing in another gearchange so the top gear spins the tires at like 235 MPH at redline in 5th and dividing that out to convert it to a RPM/MPH and then multiplying by cruise speed gets me below idle RPM until 33 MPH.

I think I’m getting EGT sensors and tuning 200° lean of peak at cruise, for gas mileage. And changing the A/F ratio until I get best average power as determined by idle to redline pulls in 2nd gear. Which means to 61 MPH because that’s what redline in 2nd works out to. So since I don’t need a precise number I can just put the car in 2nd rolling onto the onramp of a freeway and time how long it takes to get to redline from idle in 2nd a few times on the same onramp and change the fueling a bit and try again in a few minutes and see if I’m quicker or slower to redline. I’m sure the people living close to that onramp are going to love my tuning sessions. I should probably make sure I install an effective muffler.

On the frame changes, I think the most structurally efficient way to get the diagonal braces installed is to let the intersection with the hoops curve at the same radius as the bend in the hoops so the diagonals fall in the same plane as the uprights.

And just as I was finishing that thought my computer locked up for about an hour. I couldn’t get the browser to change tasks, or anything else like shut down, or open a file, or pretty much anything except be shiny. And now I’m pretty much about to shut down myself having spent all my spoons trying to get the computer functional I think I’ll finish my beer and take a nap since it’s about 0600 which is functionally like roughly 2200 to me on my sleep schedule. but before I do that I’ll publish this post.
