Fordboy (Mark?), the Performance Trends software does look similar to GearSplit and by now, would have expected someone to come up with something. Although it may be buried in another part of the software, I did not see a field for entering Cd. Does Performance Trends calculate Cd and does it graph time/distance to reach mph? I only saw a mph/rpm graph. Cd as part of the calculation and a time/distance graph are very important features for we LSR types.
My XP computer is old but still works fine for GearSplit. This may be a good thing because computers running XP are nearly giveaway. No need for an expensive computer to run GS.

Hi John,
Well, I am unfamiliar with the "GearSplit" software. My disclaimer is that I own and use a lot of Performance Trends Software, and have a good relationship with the folks at the company.
They also offer: Drag Race Analyzer Pro Ver. 2.0, specifically for Land Speed Racers.
http://performancetrends.com/Bonneville-land-speed-record-computer-simulation.htmIt is being used for simulation work on the "Carbonite" streamliner, and Rob is very positive about how well it is working. It adds cd, etc and other drag variables into the calculations.
Also available is: Bonneville Pro from Quarterjr Software. I have this and use it. It also has inputs for cd, cda, etc
There are also many members of the board that use it, including Woody. It is currently available on SpeedTalk in a $99.00 "bulk buy" deal, that SpeedTalk offers about once a year.
http://speedtalk.com/forum/viewtopic.php?f=12&t=52417There are 12 apps included and one has 52 specialized racing calculators for incredible value. There are 158 of 200 presold and only 4 days left to reach the 200 minimum.
Most of these apps are $59 to $79 each so . . . . . . . .
Of course, if you are happy with GearSplit, there is no reason to change if it does what you need. And you don't have to learn any new systems/software/etc, PLUS, there is no cost.
I use data all the time to make decisions. There are other folks who do not. Ya pays yo money, and makes your choice . . . . . . .
