914 901 Gear Ratios, Tech Article, Gear Ratio Workbook, Member Gear Set Library Options

[race914]

To maximize my 914's performance on the track, I've put together several different gear sets for my 901. This has helped me to maximize my top speed on the straights, as well as acceleration out of the corners. This has proved to be a great advantage over stock geared 914s.

I want share the info I’ve collected, as well as what I’ve learned from these projects.

I’ve put together a Gear Ratio Tech Article that includes: why you might consider re-gearing; ways to approach this project; the 914 901 Gear Ratio Workbook (MS Excel required); and references to 914World members that provide related products & services.

Lastly, and perhaps most importantly, I’ll be maintaining the Member Gear Set Library that includes the various gear ratio setups that Members are using for different applications & situations. This centralized repository will greatly facilitate finding information applicable to your re-gearing project. Important Note! The ‘right’ gear set for you is particular to many factors. To list a few, the car’s weight, suspension, engine, and DRIVER! Don’t take the gear-sets listed for a particular application as your ideal setup. Contact the owner, compare corner speeds, suspension setups, engine characteristics, driving skills, etc. All of these factors play into what will work for you.

If you'd like to contribute to the "Member Gear Set library", post your info on this thread and include:

* Applicable Category (Autocross, Street, Track (including track name)
* Engine (cc & cylinders),
* HP,
* Redline RPM,
* Tire Diameter,
* Weight w/driver,
* 1st-5th gear codes, and
* Any short comment that you’d like to pass on, or better yet, a link to the applicable 914World discussion thread on your setup

I tried several times to download your article but got a warning .

" Microsoft Word 97 Conversion " - Unable to load graphics conversion filter . Continue with document conversion .

1) what is a graphics conversion filter ?
2) what does this warning mean ?

I tried several times clicking on the yes and nadda . But on the 6th click a window opened up titled " Regearing - 080120 [1] - Word Pad " . This small article referred to a " 914 901 gear ratio work book " .

Was that article the workbook or is there another download available ? My PC has 2.66ghz and is about 3 years old so it isn't quite obsolete quite yet .

Thanks for any feed back on this one .

The article is MS Word 97 and includes the workbook which is an MS Excel 2007 file.

I can't be certain, but from your info above, it sounds like your system may be trying to open the article in Word Pad?

You might try clicking the article link again, and then instead of clicking 'open', 'save' the document file on your system, then launch MS Word and open the article from there.


EDIT 1/22: If you don't have Microsoft Word or Excel here is a 'free' option:

Microsoft provides downloads for a Word Viewer & Excel Viewer
