Blooze Own: An F355 Six Speed N* Build Thread (Page 115/126)

Thanks for the well-wishes guys! I was taking apart my engine hoist when the hydraulic cylinder accidentally swung down like a guillotine and crushed my index finger against the upright of the hoist. It's a through and through break with the part closest to my hand having also splintered. At least it didn't take out a knuckle... that would've been way worse. I look at the bright side... at least now I'll be able to get out of stacking 6 cords of wood!

Damn man, that sucks!

Hope you're a fast healer.

Let it mend, don't overdo. Gives you a good chance to finalize plans, catch up on your reading, and other somewhat "sedentary" activities....(yea, like I believe you're going to "rest"! )

If I thought it would make you feel any better, I'd tell you about some of my broken bones!

Short version....get well soon!


HAGO!

Great minds think alike! Well almost, mine is aluminum. Great work as always Dave.


PS-Sorry to see your index finger in that shape!

Ouch! I've had a few near misses with my engine hoist...but never thought it could end like that! I'll be taking better care myself now. Don't worry...I'm sure the wood will be there waiting for you when you are all healed

Well, if healing time depended on all the good vibes being sent my way, I would be back in the saddle by now Too bad it doesn't work that way. Ten days ago the orthopaedic surgeon decided it needed to be re-broken and pinned... oh-yay. That restarts the healing-clock all over again... 3.5 weeks down, 5 more to go. They've immobilized my entire hand in a cast which I'm told will need an additional month of physio to get back to normal.

Ha! A gang of neighbours felt sorry for my wife stacking all the wood so they came over and had it done in one morning! Gotta love country folk.

Well that just "sucks canal water"....as we used to say waaaay back in the 60's!

Little to no choice but to go with it and let the doc's work their "magic". Don't have to tell you this, but a positive attitude is one of the main ingredients for fast, proper healing. I'm sure yours is fine, just try not to let yourself get frustrated. Time really does "heal all wounds", problem is as humans, sooner or later, we run out of time. Don't think you're anywhere near that point yet!

As hard as it is to believe, and next to impossible to accept, there does seem to be some reason for most of what we are subjected to throughout our lives, though it escapes me most of the time, and seems to make absolutely no sense what-so-ever.

If you get REAL bored and run completely out of things to do, you can draw up the plans for my "proposed" roof, where the B pillars are angled to match the fcar quarter windows, and incorporate a frame to hold them to replace the section cut out of the original Fiero pillar; the rear window frame will accommodate the MR2 glass, and is integrated into the new quarter glass frames; the gas fill neck is moved to the fcar location, AND the Ttops will still fit! Oh yea, and research what door glass and wing window can be used to replicate the fcar arrangement. I'll get measurements if you need them!LOL

I guess if you're still bored after that, you can design a vehicle to replace the space shuttles.......

On a serious note; HEAL!!

Thanks Sage for making me a chuckle! I'm on the final leg of mending: I had the steel pins pulled out of my finger a couple days ago. The Occupational Therapist says it will take 2 months before the swelling is completely gone and until I gain full flexibility and range of motion of my finger, but at least now I can get back on the project.

During my down-time I did a bit of research on electric radiator fans. Most sites give flow rates, sizes, current draw, availability, and cost of their products and there's quite a wide range of performance for low profile fans. I looked at 14" diameter fans and found some with as little as 950 cfm and others with as much as 1850 cfm. Some drew 6 amps and others as much as 22 amps. The range of prices were anywhere from $65 to $175 per fan! The strange thing is that the ones with the higher electrical requirements and/or highest cost, weren't necessarily the ones with the highest flow rates... they're all over the map. Generally speaking though, the deeper the fan, the better the performance.

My original cooling system plan was dependent upon being able to find a suitable 2" thick pusher fan, but I was disappointed with the low flow rates of the ones I found. To get into the highest flow rates, I needed to go to a deeper fan, which also limited my choices to a puller. That led to having to redesign my layout since the fan needed to be swapped to the opposite side of the radiator, like on the actual F355. Good thing I hadn't gone into too much detail on my drawings!

In the end, I chose a relatively inexpensive fan from Perma Cool (Summit part number PRM-18124) which on some websites sold for as much as $160 but at Summit they were on sale for $61 each. They have ten "S"-shaped blades, flow 1850 cfm, draw a miserly 8.5 amps, and are 2.75" thick. I'll post pics of them once I receive them. In the meantime, here's a schematic of the new layout:



To make room for the thicker fan, I tilted the radiators backward at the top, which made better use of the available space and as an added bonus angled the radiator exhaust to better suit the angle of the louvers in the wheel well liners. I mocked up the driver's side radiator close to the angle it'll be installed, then played around with some cardboard and some Coroplast to get an idea how I'll close up the engine bay and wheel well to force the air where I want it to go:



It's by no means finished, but it's a starting point for further development. I still need to design the duct work from the door scoops to the radiator, and plan for in-service accessibility. For starters though you can imagine how the incoming airflow from the main door scoop will benefit from re-profiling the cross section of the large door post pillars. I'll probably taper the aft of the posts to form a smooth ramp leading to the inboard side of the radiators. I'll also need to do something about clearing the upper water inlet.



I've given some thought about how I'll remove and install the rads to service them too. Currently there's no floor under the radiators but that area will get closed off with a removable fiberglass panel. Removing the panel will allow the radiators to be pulled out from the bottom of the car. I'll also have to make a service panel on the inside of the engine bay to access the upper hose and fill cap.



From this last view it's easy to see just how much width there is up and over the wheel for the any airflow that can't be handled by the louvers in the liners.

Glad to see your back at it Dave! Looking forward to some winter updates.

Since things have cooled off nicely around here, I've slowed down considerably on rewiring the Fiero and have been playing outdoors.

The takeaway from this is that a high flow rating with a low electrical consumption is a LIE. A few companies rate their fans honestly... most do not.
It takes horsepower to move air... a motor can't move much air if it's not pulling much current.

A fan blade can only get so efficient, so a better indicator of fan performance is diameter and current draw (really motor power) rather than claimed CFM.

I predict you'll be disappointed in the performance of these units. The only way 1850 CFM could pass through the frame with the motor pulling 8.5 amps is if they were mounted in the path of a tornado.
