Weights and Measures

« **on:** April 08, 2008, 01:57:59 PM »

I'm wondering if anyone in SCJB land has weighed the following separately...

1. Engine (make, model, induction exhaust... different types ok)
2. Pump (w/ or w/o snoots, extentions, intakes, nozzels, more types the better)
3. Hull (make & model plus a dimension from the transom to where it balances)
4. Tanks (empty w/ capacity in gal.)
5. Driver suited up (vs. in your b-day suit)

I would like to set up a little CG calculator and want to get an idea of how they set up compared to where we think they should be set up. This should help everyone in ordering drive lines, fin placement, best location for tanks, driver's seat etc. My hope is I'll develop it as free ware (probably a modified excel spread sheet) on the site if our fearless leader thinks it's ok.

I'm good with it as long as theres a big fat disclaimer that doesn't hold anyone liable

i dont have any of the above to weigh for ya tho.

That's cool - we can set it up so there is no true answer to any specific question. Just a "what if" tool for guys that 1) don't know what they have and 2) want to aim for a specific CG during set up. I would not nor could I make any recommendations.

Hey Marc, on that book you showed me, I thought I read the 12JC weighed 125 pounds.

That pump looks killer.

« **Reply #5 on:** April 08, 2008, 04:54:34 PM »

The book says approx. 100lbs but I just put mine on the scale and it was 70 lbs even.

I have my electronic scales for weighing my race cars that we could weigh a complete boat and trailer, then weigh the trailer without the boat to figure the difference.

Only problem is you have to raise the trailer with a jack to place the wheels on the weigh pads.

« **Reply #7 on:** April 08, 2008, 06:49:21 PM »

I really wonder how well this would work out. There are so many different configurations for the same sort of boat/trailer configuration. Then you would have to take into account how each trailer was made and how the hulls were laid up in the molds.

« **Reply #8 on:** April 09, 2008, 08:51:31 AM »

Differences in weights is the point of the calculator. As we get more data on different hulls I hope we can have a list of different boats as the database gets bigger. If you have an idea of where to put a fin for instance you could check it with the calculator. The info for the hulls needs to include the moment as well as the weight. so we need to know the distance from the balance point to the transom as a minimum. It would be nice to find the height above the keel too but I haven't figured out an easy way to get that yet and I couldn't expect everyone to be able to supply that info anyway. a few assumptions would have to be made. PS thanks for the pump weight Marcsrollin... I take it that's as shown in the pix.

maybe that weight included the intake too

i weigh 289 naked!

theres a start....which = need a bigger engine than normal to move my big ass

« **Reply #12 on:** April 09, 2008, 10:08:56 AM »

Chromey I have you down for 289 now make sure you race that way so your weight and balance figures will work out. We wouldn't want you to be bow heavy simply because you put on your shoes!!!

« **Reply #13 on:** April 09, 2008, 11:13:32 AM »

Thought I'd work up the graphics for the calculator. I'll work on a work sheet later then I can add in the formula and try it out.

« **Reply #14 on:** April 09, 2008, 03:30:49 PM »

my engine weighs 625 lbs with the mounting plates, fuel pump, alternator (mini denso style), top mount IMI starter, Moroso vacuum pump, MSD 6al, MSD HVC coil, and bassett twistie headers installed on it. Its a tall deck brodix aluminum block with Pro Filer aluminum heads, Pro Filer Hitman aluminum intake and a Dominator carb. Hope this helps Wiz.

Outstanding Cyclone !!! If anyone has an Iron Block Comp Jet motor weighed that would be great too.

« **Reply #16 on:** April 10, 2008, 11:32:04 AM »

Here is the basic calculator please replace the weight and distances listed that was just to make sure it worked...
We now have a basic weight for an Iron block with same build to Cyclone's Aluminum one.(thank you GM Performance Catalog)

Wish I didnt run the trial version of that program out of time!!!

« **Reply #18 on:** April 10, 2008, 02:33:00 PM »

What trial version are you speaking of. Excel? if you have any of the major spreadsheet softwares you should be able to convert it through the other version. If not an old version of Excel you could pick up cheep.

Yeah the trial version that came with vista. Im gonna see if i can get it to open up using the older version I have.

Only if your version works in that crappy Vista. Read an article about how you can set up a PC with a dual boot so you can boot up with Windows XP or Vista. Pretty sweet.

Yeah vista sucks. I would rather run windows 3.1 than this dog shit.

Vista is fine! People are just unwilling to adapt to something new.

« **Reply #28 on:** April 24, 2008, 06:18:51 PM »

Vista isnt the greatest, im just puterin along with it. I didnt even try to use the office trial version, cause afterwards it costs $$$$$$$. Go to openoffice.org and download the FREE, very similar office software. Will open any spreadsheets, powerpoint, excel, anything!! And its FREE!! It works great Microsoft sounds like they might be backin off the no suport for XP thing also Just my 02 guys Mark

I have to agree with you! No one wants to change. I just bought a new PC and it came with Vista and the more I play with it and get use to how it works, I like it. I hated XP when it came out and once I made the change and got use to it, it was fine. Hell, I'm an "X" Network Engineer and use to have to stay 6 months ahead of what everyone else was just getting. The latest and greatest PC that just hit Best Buy is 6 to 12 months old technology. So can never be up to date. I do know that I've got to buy a new paint/graphics program.
