Title: GEARSPLIT program under Win XP
Post by: }{ead$hot Zod on January 26, 2005, 02:42:00 PM
Anyone able to get the GearSplit program to work under Windoze XP?. I tried getting it to run with the "Windoze Compatibility Wizard" to no avail. I would prefer not to run it under my "V4/VGC laptop"   :mad:

I have it running on two xp machines, main computer and laptop with no problems or capatibility problems.
 
 I would uninstall and reistall it without using windows compatibility wizard. I just installed it without any problems.
 
 Let me know how you turn out, and I will put up a help forum for the Gearsplit program where questions and answers and be setup and remain there.

Jon, it wouldn't even install on that machine. argh!!!
 
 Well as luck would have it. It loaded flawlessly on my other XP machine. Looks like a windows reinstall on this one, but then again the beer is closer to the other machine...decisions decisions.....

Ok so I just want to make sure you got it running on one of the XP machines without problem. Please let me know.
 
 Thanks

Great if you have any other questions about Gearsplit please post here under a new topic.
 
 Have fun with it, very nice program EMS has provided us with.

I watched Dave work for Months to make that program happen...  it's an amazing bit of software truly designed for us....  
 
 Just wanted to take a minute and thank Dave for doing the work...

It's a very fascinating program. And the fact that we can plug in our own numbers makes it more valuable. And with our own forum here we would be able to give new users numbers that we have come up with or added. I have already added the three transmissions that fit my truck. Now I just need to figure out how to get the aerodynamic coefficient of my truck, "brick" isn't an acceptable input  :)

yeah a brick isnt a good one, there should be some published reports that can get you very close with your  application.

The closest I've found online is a 0.5.

As a quick side note here. Many programs when installed will replace the shared .dll files on your computer with a version of their own that should work ok with Windows and their program. That is generally the reason you have to reinstall Windoze. Not because it failed but because another program changed it. All this program does on install is check to see if you have the Borland database admisitrator installed or not. If it does not have it it will install it other wise it just adds to the list of installed databases.
 
 The one thing the documentation may not allude to but might be obvious is that you can add to the lists of transmissions in gear manager and then add the appropriate gears that are available for the differnt gear positions. Take a look at the 'Gear manager' function and you will see what i mean. I did not think of it at the time but under gear manger you could add an enry for Winters Quick change and then list all the drop gears available. Unfortunately you will not be able to drag and drop it into the drop gear box as that was never anticipated but you will have a handy reference of the available quick change gears and whether you have a set on hand or not. Same goes for a Jerico or Tex Racing but that gets tougher as they have a very hard way of keeping track of the gear ratios as one entry will affect another unlike a Hewland for the most part..

Is there anyone interested in a coastdown test program to help find the Cd of vehicle?
 
 Free if it will be used. on another note it was mentioned that the cost of this software is split between Jon Amo and myself with landracing.com getting 50% of the proceeds to help him keep this site going and up to date.
 
 On another note a lot of help was provided by Mayf from the landspeed list as well. he helped a lot with getting the math straight..

Gear Split is Wonderful! after a week into it, i've learned more than years of trial and error and the car isn't even built yet.. The "coast down program for Cd would much appreciated..
 
 thanks

Dave I'd love to see a coast down program... Beckett and I have talked about it several times... but if it's much past getting correct change the math can be a bit overwhelming...

I would love to have the ability to use a coastdown program. I know Banks used one and makes mention of it on his site (http://www.bankspower.com/sidewinder-dakota_platform.cfm).

Dave, if you made a coastdown program I know I would use it for my cars. Thanks, Tom Gerardi

Dave, the new program would be very welcome.  And if this, as well as the original Gearsplit program, were able to also run on a mac platform this would be fantastic. I know this is asking alot.

I have no plans to do anything for a MAC platform if there is a windoze emulator for the MAC that would be your best bet. For right now that is my stand in the future if any complilers and linkers come out that will do both windoze and MAC it might change but until then i see little hope for any MAC stuff.

Keith - If you are interested these are the coast down formulas . Speeds are in Ft/Sec (mph x 1.47)
 
 If you're timing the seconds to coast from speed (A) to speed (B):
   (A) minus (B) divided by coast down seconds divided by 32 x car wt. = drag in Lb.
 
 If you're seeing how much speed you loose while coasting for a given distance:
   
   Speed lost x 2 divided by coast down Ft x car wt. = drag in Lb.
 
  Lb drag includes aero and rolling friction and is for the average speed . The greater the change in speed the more the drag curve affects the accuracy . The accuracy is as good as the speedometer and the observers eye & thumb .

aero and rolling have to be separated to get any meaningful answer.

This GearSplit sounds very interesting, where would I find a copy of it?

Title: Dodge pickup Cd:
Post by: Rex Schimmer on January 30, 2006, 11:44:06 AM
Headshot, I read were you think that the Cd on you Dodge pickup to be around .5. NOT EVEN CLOSE! Your truck is not a brick, it's two bricks! A short one setting on top of a long one. The Cd for the bottom may be some place below 1.0 because of its length but the cab, being so short probably has a Cd above 1 and combined  you have a brick! It is not the shape of the front of the car it is the shape of the back that counts most.

Paul Van Valkenburgh has a good discription of finding the Cd via the cost down method in his book "Race Car Engineering and Mechnics".

Saw a recent Myth Busters where they drove two identical pickups down the highway until they ran dry with one following the other.  It was a long ways on a full tank, over 300 miles if I remember right.

Anyway the test was to see if the tailgate was down if you got better mileage.  Well the one with the tailgate up went quite a bit further.  

They said, I don't know if it is true or not, that the newer pickups are designed so that with the tailgate up it makes a bubble of air circulate back forward to the cab and up the back of the cab which then tumbles in a circular motion that stops the air going over the top of the cab from getting sucked in behind the cab thus streamlining the air flow (Some of the F1 cars use diverted air to help with the airflow around the open wheels and I've considered experiment with that later on my lakester if it ever actually runs.).  

Hope you understand what I was trying to explain :roll: .  I think they even put Styrofoam balls or something in the back to see how the air really was circulating and it followed the above statement.

Disclaimer:  All of the above could be true or a myth since I saw the show a couple weeks ago and at least 1/2 of those memory cells are no longer with me :cry: .

c ya, Sum

You can run XP programs virtual in WIN7! There is a demo at the link on the jpg!  :cheers:
