Waiting on the door installation people

OK I have selected storm doors to replace the ones installed when the house was originally built in 1985, now I’m waiting for the installers to arrive and measure the door to get the right size storm frame. As this is one of the few standard size things on the house, I don’t expect too much hassle getting it installed.

One thing I have to say, it’s easy to get through the door once it’s open, the frame is 3′ x 6′. Looking through the Lowe’s listings this is the largest standard door available. There are taller doors, but they are only available by special order. There are lots of doors that come narrower, but I didn’t see anything wider. So 3 by 6 is as big as you can get without spending buttloads of money. But the installation people have to verify that in person so they get the right thing.

I have been practicing with the bender for the plastic stock of the frame and exhaust for the Mini Sprint-T, as the exhaust in particular requires lots of work to get right and there is a bend for the muffler/tailpipe in particular that really needs to be done right. To simulate the thin wall exhaust tubing of the 1:1 scale vehicle the end of the exhaust tip needs to be filed to a knife edge from the inside and the inside painted matte black or matte silver. That’s something I’m going to have to research, does E85 leave a carbon deposit when tuned for best power? I already know that the highway mileage tune for 87 octane won’t, as it is about as lean as the engine will run right with, emulating a tune that let a ZO6 Corvette get just over 38 MPG in a real-world highway test. For airplane drivers this is the car equivalent of tuning 150° lean-of-peak on the EGT. And for people not aware this is over 40 MPG steady-state from an engine that displaces 427 in3 (7 liters) and put out ~500 HP at the rear wheels back in the day. But anyway the highway tune will not remove carbon deposits at the end of the exhaust, so if the tune for E85 carbons up the exhaust then I need to emulate that in the model. And I just checked the E85 forum and there are 3 posts that say they don’t get any carbon from running E85, and one that said he still has carbon in his tailpipe from the 87 octane the dealer put in when he first bought it, but nothing more than that in 5000+miles since he bought the car, so I’m going with the matte silver for the inside of the tube.

The fuel map is going to look really strange when I get this tune done, because most of the map will be slightly rich except for the RPM block and throttle setting for steady-state freeway cruise at 60 MPH which will have a “hole” that leans the engine as far as it will go and still run right. On 87 octane this will be leaner than the max NOx point so low CO, CO2 and middling NOx.

And I have been sitting here writing for about 3 hours waiting to hear from these people, and it’s about 1630 CST so I’m going to assume they aren’t going to answer today. And this is a good word count to stop at, because I don’t want to bore anyone today. So, I have to go out again tomorrow to deposit a check, which means going on the bus again. But not as bad as Black Friday in the rain.
