GPS - What kinds are best?

[racin jason]

use a suction cup mount on the windsheild and it will be in the line of sight and work well. looking down at the dash at el mirage is not the hot setup unless you are hunting for dirtbikers.

Good Point.  That got me to thinking that our Z06 has a heads-up display.

So I wonder if something like this would work?

I own that device and its made by a company called Globaltop.

I paid 99$ for mine.

It works great.....*except.

You can not see the display because of the stark white background of the salt.....period. I dont care if you use 2X thick window tint film that they provide in the kit.

We found this out in 07 and had to use a 3X4 inspection mirror taped to part of the roll cage to see it.
This was still a pain because my pop is about 4" shorter than I am, and this made swapping drivers a pain (the mirror was out of line of sight for me but worked great for my dad.

I will however say that this device has a very large display and could be used to make a very good speed indicator for your vehicle. You will need to glue a piece of mirror (glass or plexi or mirror vinyl) to the back of the windshield and mount the thing so you can see it. We had to jerry-rig a setup at the salt and it was not perfect. I am now considering re-using the unit (it gave dead accurate readings unlike my expensive Nuvi unit) and just do a nice install using the mirrored vinyl. People said the thing would vibrate and you will not be able to see the numbers, this was in fact incorrect and you could read them very well (I and to dip my head a bit to see the mirror) because of my bad salt install.
Other than that, the unit is quite cool and is a cool way to get a heads up in your personal ride....but for the salt you will need a mirror.

*this unit was mentioned previously in this thread as well.


BTW:

Here is the same unit for 70$.
THis is where I got mine.

Joe,
Great When can You START ! I'm kinda LIKE the Blind leading the Blind{Racing a V-Twin DOHC} Then trying to Keep Up with You and the Gang{J/N,J/MC,ECT} on my FLIPPIN HD V-rod !!!!
All's I want is a Friggen 200mph club Hat and at this Point I'd Race just about anything to get one !
ONE GOOD THING GOING BROKE HAS TAUGHT ME is if you want it done{Fixing my Broken Bikes} you better Learn to do it Myself !
I Have ALL THE RESPECT IN THE WORLD for all of the Builder's that Race them Too ,and I have the scars on my hands to prove it !
I'm 1/2 Polish so I have to do thing's the Hard way,and Going Fast on a V-rod is A BITCCH without much support{I'm the R&D Sponsor} !
So I'm a LITTLE BITTER LATELY.

Welcome Home and God Bless YOU AND all THE TROUP'S!
Thanks again,,

Yeah but you have Dave and his buddy "Mo" to help... so it seems to work well....even for an older motorcycle....

GPS is not really a "luxury" item if you are doing licensing passes or have a speed restriction.

Speedos that rear wheel driven aren't useable unless you know the slip and growth, front mount speed sounds like a good idea though.  Tach ain't reliable with an automatic, and 1000rpm = 52mph for me.

Someday I hope to not need one.

GPS is not really a "luxury" item if you are doing licensing passes or have a speed restriction...........

With the 25 mph window on the licensing passes you have quite a bit of leeway.  Even with a torque converter, you should know the slippage to be close enough and you should be fine using one of the spread sheet applications or on-line calculators like on my site.....

........... or other sites.

Thousands have licensed prior to GPS and I certainly have other places I plan on spending the money vs. a GPS,

Don't buy one then.  I need one.  I was born with a 30lb right foot.  Hard to find shoes, but I suffer through it.

[McRat]

Here's the calculator I use:  http://www.mcratracing.com/allisonratios.xls 
Factory redline occurred at 110mph, so the base values aren't correct anymore.

[Cajun Kid]

The speed sheets  from Sum's site work very well.... On pavement/concrete with no rear wheel slippage.

I checked it against my tach, my speedo and the ECTA timing slip.

My Speedo said 130, Sums chart said 128 and the actual timing slip was 126.98054

That is very acceptable spread.
