Holley: SELECTING A MECHANICAL SECONDARY CARBURETOR tool
By SuperDan in Software, Calculators
I hate reading nomograms! So I took the one on the second page of this Holley document on carb selection (for sizing mechanical secondary Holleys):
http://holley.com/da... nical/Selec...
...and fit a second order polynomial to the inputs (minimum WOT rpm and displacement in cubic inches):
cfm = 0.000886*WOTrpm*disp + 0.000159*disp^2 + 0.0000066*WOTrpm^2 - 0.345*disp - 0.0554*WOTrpm + 439
Checking it against that nomogram, it seems to reproduce the results of drawing a line across from WOTrpm through disp to find the cfm needed, within +/- 6 cfm, when I checked it against the 10 data pairs I used to read off the graph and then check it. It all really hinges on how closely you read that graph to come up with the input data, and how accurate the data they used to make the graph with actually was. I used a graph that I tweaked to exactly match each of the 3 axes of the original graph, zoomed in to very precisely read the data off of lines I drew from several WOTrpm/displacemt pairs over to the cfm axes, as well as one graph for each axes to find the non-linear formula for each of those. Like I said, I geeked out.
Here's a spreadsheet I made up to do the calcuations:
http://alteredz.com/...chSecSizing.xls
(same file as the download, the link is provided above too)
All of my work is shown on the calcs sheet, if you want to check my math
Just put the WOTrpm (minimum rpm for WOT use) and displacement (in cubic inches) in the yellow boxes and the answer appears in the magenta cell to the right of those.
Watch out, we have no idea how accurate the data in that original graph is! Also, they make no mention of whether the type of boosters are, the throttle plate size, or the venturi size. I believe all of these play in the selection.
Also, note that Holley and BG may have a name for a carb based on a cfm number but the total cfm they flow can largely differ. BG's 650 DP Mighty Demon flows 830 according to them, so if you pull 830 off of that graph, you'd want a 650 Mighty Demon!

Quarter Mile Calculator
By SuperDan in Software, Calculators
This is a quarter mile calculator that uses visual basic for applications within excel to calculate position, velocity, and acceleration based on vehicle parameters.
The input accepts the following parameters:
weight
drag Coefficient
rolling resistance
traction coefficient
shift points
transmission gear ratios
differential gear ratio
Tire Diameter
Engine Torque Curve
The engine torque curve assumes rear wheel torque and accepts 7 datapoint pairs. The program interpolates between the given data points using cubic spline interpolation (gives a smooth twice differentiable curve).
The output to the dialog is all of the drag strip parameters (60' time and speed, 330' time and speed, 660' time and speed, 1000' time and speed, and quarter mile time and speed). Further, all of the data for a 50 second run is output to a spreadsheet (100 samples per second).
The program predicts the times for my car to within 0.1 second and within .5 mph.
Currently, the program is specific to a manual transmission powered car. I would like to expand it to include automatic transmission equipped cars. The source code is open and I invite criticism as long as it comes with suggestions for improvement.
IMPORTANT: In order for this program to run properly, you must set your excel security level to medium. And then when you are prompted to run macros say yes.

Toe-in converter
By SuperDan in Software, Calculators
Most of us think of toe-in as measured in inches, but my local alignment shop's machine only measures in degrees. So I built this spreadsheet to convert from one to the other.

Datalogging software & source, Mac compiled & PC
By SuperDan in Software, Calculators
These are a couple of pieces of software I've developed for tuning ECM's. I've included both OS X executable as well as the code itself. They're written in RealBasic, a cross-platform, object-oriented, compiled version of the old stand-by language Basic. I'm hoping that someone who knows what they're doing can take a look at these programs and whip them into shape, or at least give me some good suggestions, hints, ideas - I'm not a programmer (as will be obvious once you look at the code).
The first one is called "ALDLx". It's a data logger for the '7730-and-family ECMs. It has been patterned after a couple of older pieces of software (ALDLMON and WinALDL). It was designed from scratch to work via a USB/Serial adapter. As it stands it works pretty well (for me!), but it's spaghetti code at best (in spite of being Object Oriented). It compiles under 10.3 and 10.4, hasn't been tried under 10.5. It also compiled it on the Windows 98 version of RealBasic, as an experiment, but didn't have a chance to try it.
The second one is "PKTx", is a little utility that does only one thing: sends a .bin file from the Mac via USB/serial adapter to a Romulator. That's it. However, the killer app is that you can run a program like TunerPro or TunerCat under Virtual PC, modify it in a "shared" folder, and send it up to the Romulator on the fly every time you save it. So you can datalog with ALDLx, modify the .bin with TunerCat/TunerPro, and send it to the Romulator all in one smooth action.
Anyway, if there are any brave programmer/gearhead types out there, I hope you take a look at these things and can maybe do something with them.
Tuning Distro.zip is approximately 7.6 mb in size.

Header flange dimensions
By SuperDan in Drawing Files, Templates
This is a solid model of a header flange for a P90 head.
The file formats are STEP, and IGES. I can post in other formats if you would like, just PM me and I will save my file in
something you can use.
Also attached are some solid models for a header design. This isn't the one that I went with, but it still looks pretty
cool. Note that the flange is attached upside down and uses the wrong bolt pattern for the middle flange (my mistake). Use
the flange only file for flange dimensions.

Ground Control Camber Plate template
By SuperDan in Drawing Files, Templates
Ground Control Camber Plate template as drawn and designed by Zzeal in his original thread here: http://forums.hybrid...ad.php?t=152601
I scanned in a copy of the template to .pdf format. I taped it to a standard 8 1/2 x 11 piece of paper and fed it through my nice top-feed scanner at work so that it wouldn't reduce or enlarge the size at all.
I confirmed that the size doesn't change by printing it from Adobe Acrobat, you just want to make sure after clicking print that in the "page handling" section of the print window that under "page scaling" to select "none" and uncheck "auto-rotate and center" and it prints out perfectly 1-1 to the original template made by Zzeal.
One more tip, you'll probably want to print it on the thickest paper your printer can handle so that when you cut it out it isn't super flimsy like it will be if you just use regular printer paper.

Turbo Swap Wiring Diagram
By SuperDan in Drawing Files, Templates
Since I just finished a swap, I decided to document what I wired, and how. I was going to sell it on ebay but decided not to waste my time...lol. This is for wiring an 82-83 into a 75-78 as far as I can figure. Year models may vary so check your manual and wiring diagrams!!!!! I'M NOT LIABLE FOR DEATH AND DESTRUCTION. unless I choose to take credit.
Option: You may omit the ZXT Fuel Pump Control Module by simply grounding the negative side of the fuel pump.
