It took me three tries to type that headline because my forearm stuck to the chair. Anywho URL:

I had a hard time getting the URL to share this, and I have been wanting to share it since last week. This is slightly out of the ordinary for this blog but I have linked over in the side bar.
I went out to get lottery tickets the long way and took the long way home for about a mile and a quarter walk. My old feet did not take kindly to the abuse and started to swell inside my shoes, and let’s just say the results were neither pretty nor comfortable.
I’m still thinking about the alternator and driving the stock water pump on the LS engine, and discovered after a few minutes that no matter which side of the engine I hung the alternator I was going to need an idler pulley to turn the water pump the right direction, because physics. The rib side needs to drive the alternator and the crank pulleys, the flat side needs to drive the water pump. That means the belt has to change direction twice to get everything running the right direction, and that means an extra idler, or two alternators with one placed in a strange orientation to be running the right direction while driven by the wrong side of the belt. Personally, I prefer an idler and a high amperage single alternator over trying to wire in two alternators to the electrical system. But it is feasible to run two alternators if you include blocking diodes to prevent power from trying to go into a dead alternator. I think the technical term is a “crowbar” diode to stop the flow of current if the alternator shorts out.
And this came in as I was composing this, Mrs. the Poet is doing some volunteer work for the election and has some information about us on the voter registration list, and there was a strange phone number attached to our names. I did a reverse lookup and it either is now or at sometime in the past was for a church in Grand Prairie, which is a few miles down the road, and about three cities are between us and the church. Looking further had my name and my father’s birthday attached to this number, which is understandable because we have different middle names to prevent me from being a Junior, but the same first name and middle initials. And obviously this is not in my stage and pen names because he was never “Opus”. He’s always been “John” or “Johnny”. But it was funny to see me listed as 85 YO, and a whole bunch of old addresses where we used to live. Further investigation shows another person currently attached to the number over in a different part of town who I never heard of. A quote from Alice seems appropriate: “Curiouser and curiouser”.
Now, back to the Sprint-T, I have also been thinking about that intake manifold and how to make it. One thing I was thinking about was to use carbon fiber around a positive mold for the runners and just doing everything into a single unit that will bolt to the heads. I have been thinking about mounting the injectors in the roof of the plenum aimed at the mouths of the runners for charge cooling, since the runners are all downhill to the mounting face on the heads. All of the fuel sprayed into the runners will get to the cylinder it was intended for, eventually. Now making sure the fuel delivered is the fuel needed will take some finagling in the tune, but I don’t see that as an insurmountable problem so much as a calibration issue with on-throttle enrichment. This is a programming function that acts like the acceleration pump in a carb, except in software. And calibration is similar to calibrating the pump shot on a carb set up, by trial and error on the street or track. The tuner has to start with enrichment disabled, then gradually increase enrichment until the engine runs smoothly even when throttle settings go from idle to wide open in a fraction of a second. The tricky part is a little too much enrichment acts like a little too little, a slight stumble on tip-in. That’s why taking very small steps is better, because the tuner is more likely to hit the sweet spot in throttle response before going past it.
And this looks like a good place to put this post to bed.
