Still working on the design

I can’t leave the house with the rain and thunderstorms and the flood watches, so I have been reading superhero books on my Kindle app and moving boxes representing assemblies around in my CAD program.

OK my current design method is to assign things a box that describes the space they occupy, rather than the actual object itself, and then move the boxes around until there’s no overlap. Some boxes are fixed, like the engine/transmission box and the body box, while some are not even fixed in size, like the radiator box that changes width depending on the radiator I’m trying to fit. I think there is a possibility the smallest radiator in the catalog will be enough to cool the Pentastar after seeing the stock radiator for one of the vehicles it is installed in by FCA. That simplifies packaging considerably, because I can figuratively put that radiator beside the steering box and have room left over for a bowling alley. The joker in the deck is the OEM radiator is double-row but the catalog radiator is double-double-row with  1/3  less frontal area but a 2.25X thicker core with more fins, and I lack the data to make a direct comparison. The “double-double” refers to the tubes in the core of the catalog radiator having more than twice the heat rejecting capacity of a round tube, making the double row core the equivalent of a 4-row. There is a simple formula for comparing radiators of different designs, but catalog descriptions rarely have enough information to allow its use. And that goes double in this case, with different chunks of the equation missing from the 2 catalog descriptions. But it is my SWAG that the 22″ catalog radiator will be roughly equal to the OEM radiator, especially after I learned the replacement OEM radiator was also used for much larger engines and is just sold as a replacement for the Pentastar because it fits the hole. Ima just hafta put a huge electric fan on the catalog radiator to make sure there’s enough airflow to remove the heat, which is what I would have had to do anyway, just maybe not as huge as I’m thinking about using now.

The radiator box combined with the steering box are the same width as the engine box, which is the same width as the firewall but extends a touch to the right because of offset to balance out my “big bones” sitting behind the steering wheel on the left. Which is a very roundabout way to say the radiator and steering box are together the same width as the firewall. And that I could install a wider radiator without increasing the frontal area of the car. This also means that there will be a large hole to the left of the engine that could be use as an escape path for cooling air, or a place to install an oil cooler facing sideways. Looking at the picture right now there are several places to install a small oil cooler, above the steering box there is a 5″ wide by 18″ tall space, there’s a 7″ tall space under the radiator that could run the width of the front end if the hoses would fit under the steering box. But as I don’t see any oil coolers near those sizes in the catalog…the question is moot.

And I just found a picture online of the engine in side view, with a tape measure in clear view to use to scale from and all the driven bits hanging off the front with the belt and pulleys exposed to measure. Something to make the engine box more accurate in the for and aft dimension, might mean a bigger box, might mean a smaller box, but either way it’s a more accurate box.

And writing note, when I get on a roll writing it’s pretty much stream of consciousness, but I still “feel” the punctuation and capitalization. What I don’t have a feel for is when I need a paragraph break. And my proofreader program knows fvck-all about paragraph breaks so I don’t get a blurb about needing a paragraph like I do about passive voice or homonyms. What I’m trying to say is I know I need more paragraph breaks in my writing, I just don’t always know where to put them.

Having contrary thoughts here

I just read an author’s use of the Bechdel Test as a bare minimum qualifier for equity in a story. This got me thinking of a story that had no on-camera men, all the speaking characters would be women. And the only thing they would talk about would be men, and other women. Set it in a nursing home and call it “Gossip Grannies”. None of the speaking characters would talk about themselves or any of the other speaking characters, and each weekly arc would be about a particular combination, guy-girl, guy-girl-girl, guy-guy, girl-girl, whatever. For all my comic artist/writer friends here’s a free setup, just put Based on a Concept by Opus The Poet in the credits.

I’m a writer so I must write

If it seems like the posts don’t have a lot of content lately you’re right. I’m writing because I have to as a writer. Also to get better as a writer I have to write something as often as I can. So, I’m writing.

I’m still torn about tires and wheels for the hot rod. On the one hand for best performance at Goodguys I need to run a short wide tire that gets the car down lower and drops the CG which improves cornering power, and a taller tire that lets me clear speed bumps for normal driving around, OR I could get one set of wheels and tires that are just tall enough to get me over the speed bumps and still has the good grip for Goodguys. If I go with two sets of tires I’ll run the 255/60R15 BF Goodrich TA Radial as my dedicated street tire and the Maxxis Victra VR-1 245/40R15 as my dedicated race tire. If I go with a single wheel/tire for everything I’m looking at the 245/40R17 in a variety of brands up to 285/40R17 also in a variety of brands, and maybe a 315/35R17 Goodyear to get the grip and barely raise the bottom of the car over speed bumps.

There are three reasons for going to the 17″ diameter wheel, the first being that there are many more brands and sizes of tires available in 17″ diameter wheels than 15″. The second is there is room to stuff some huge disk brakes by T-bucket standards inside a 17″ wheel. For a T-bucket 11″ front brakes are huge, but I can easily fit a 13″ front disk inside the 17″ wheel and there aren’t any bigger brakes I can fit to the early Ford spindle. Unfortunately the rear brakes are limited by the constraints of the knuckle from the minivan to be only 11″ or so. Bigger brakes mean more stopping power from the same pedal pressure and calipers with less fade. That means shorter stops or less time braking and more time on the gas for racing. The third reason is it’s much less expensive to buy 4 wheels and tires than 8, even though that makes both sets of tires last longer. So I may have to give up a tiny bit of cornering grip to get better braking and much lower costs. Running 17″ wheels with 40 profile tires looks strange on a bucket though, so I might go with the 15″ tire combinations in spite of the extra cost, because in reality the 11″ brakes are just barely adequate for the weight of the car, and there is room for 12.2″ discs on the front with special low-profile calipers that are more than barely adequate. The 255/60R15 TA Radial looks “right” on a bucket, while the 245/40R15 Maxxis tire has much more grip and is roughly equal to the grip from the 17″ tires between the reduced center of gravity and the tread width.

Ugh! I hate when stuff like this happens, needing to make a decision without enough data to make the best decision, and not enough money to get the data.
