What I did this 4th of July

Well I went out and did some shopping as depicted in the photograph.
It needs a name

This is my new exercise weight and car repellant. I needed something heavier than my 2 pound hand weight but was not comfortable with buying 5 pound weights which was the next step up, plus I only have the one free hand when walking. It needs a name, but I’m not comfortable with naming it after Thor’s Mjolnir, because number one it can’t live up to the name, and two I’m not Heathen or Asratu, I’m Eclectic Wiccan and I follow (sort of follow) a Greek forge god. Actually I look to Hephaestus as more of an inspiration than a focus of worship. But that still leaves me with a nameless hammer.

I also got some nut driver sockets for use with my drill, and some 12″ by 12″ (cut size) wash cloths that were free with the coupon. And on the way home I redeemed a coupon for 2 Ultimate Cheeseburgers for $5 and added small fries and a small drink, and now I’m stuffed. I ate an actual pound of meat, plus cheese and buns, small fries and a Coke Zero, and I was still able to walk the half-mile from the convenience store where I bought the Lotto ticket to my house, but I think I’ll skip the ice cream tonight.

Also, I got the installed measurements for the Subaru EJ engine in an Impreza wagon and I have to say it’s looking pretty good. The height and width are slightly more “as installed” but the really good number was the firewall to front pulley number. This is the installed distance between the two points and allows for 11″ of clearance for the intake and the intercooler and is all behind the rear face of the block. This is longer than the input shaft on the T5 which will handle the output from the 2.5l turbo engine just fine. And that means I can move the engine even further to the right because the bellhousing will be clear of structure. That’s a 250 pound engine mated to a 80 pound transmission for a total powertrain weight of 330 pounds. The offset has to balance my weight of 225 pounds in driving suit and helmet that has an arm of 11.25″ or 2531 inch-pounds or engine offset of 7.67″. That’s going to hang a lot of the right side of the engine out from under the hood. When I started on this project I was looking at a 545 pound engine bolted to a 125 pound transmission that only put out 100 more HP. I went from 1700 pounds without driver to 1360 and lowered the CofG significantly and I only need to tune an additional 15 HP to get the same power-to-weight ratio. That’s a tank of E85 and a few minutes on a dyno adjusting boost. Seriously, at this point I have to say I think I have found the closest thing to a perfect engine for this beast, if I can find one to install.


Role playing game yesterday was fun, but it made me cancel my trip today

I was doing pretty good on the back pain issue until I caught the bus home from yesterday’s game session. There was a hole in the grass that the mower just skimmed over disguising it as a perfectly flat surface, and of course I stepped in the hole. What causes me the most pain is not the uneven surfaces I know about, it’s the sudden drops into places I can’t see. Stairs are usually no problem unless the surface I’m stepping on is not the surface I will be walking on, like a loose stair that is actually sticking up that I expect to take my weight immediately instead of the milliseconds it takes the stair to bottom out. Well hidden holes in grass are the same thing, I expect the solid surface to be in one place and it’s an inch or so lower so my back is not properly set up for the landing, which then really hurts.

On the T-bucket front, someone suggested another engine family that would work, the Subaru EJ. It’s compact, about 28.5″ wide and about 15″ long for the 4 cylinder versions, about 22″ long for the sixes, and has dual overhead cams and 4 valves per cylinder, and later versions have VVT (Variable Valve Timing) and some 4 cylinder models had factory turbos. Now the best combo for the GoodGuys events is the VVT and the turbo, which has good low RPM torque combined with high RPM horsepower. That’s because VVT adjusts intake and exhaust events for best power at each RPM point and the Subaru engine lets the computer adjust intake and exhaust separately for even better low speed power and response. This lets the turbo spin up quicker which improves mid-range and upper RPM breathing and power. Engine weights are reported to be about 200 for the 4 and about 300 for the 6 NA engines with the factory turbo adding about 50 pounds to the 4, and not available on the 6. There is an active aftermarket for both versions but biased towards the 4 cylinder, so light weight and lots of power can be had. The stock NA and Turbo versions do very well in SCCA Solo racing, so GoodGuys in the bucket will be mostly matching gear ratios and transmission ratios so the engine is in the best part of the power curve when power is needed. Most of the engine weight is at crankshaft height which helps keep the CG low which aids handling. The debate is does the low RPM grunt from the 6 offset the higher weight and reduced power because of no turbo? There are kits to install the turbo from the 4 on the 6 that are reputed to retain the low end grunt while exceeding the power available from the 4. And there are kits that purport to give the turbo 4 the same low-end grunt as the 6, without increasing the weight over the factory turbo or reducing ultimate power produced. But in any case the main advantage is the low center of gravity offered by the horizontally opposed cylinders of the Subaru engine.
