of the non-musical variety  Thinking of changing the dials in the T3 to something more 'sporting' (might as well whilst the dash is out, they're a curse word to wire otherwise!)... never been a big fan of having masses of aftermarket dials bolted all over the dashboard so have been looking at other ways of doing it. As standard they it has three round pods with clock, speedo+odo and a multi-jobbie with fuel level and warning lights on the end. I think the outside two are 52mm but the speedo is (or looks) bigger. Just found a set of Porsche 911 dials, anyone know how big these are? I am NOT hacking my £10 perfect no-cracks dashtop to get them in They seem to have one with oil temp and fuel on, one with oil temp and pressure (which seems odd, unless they're off different cars? two oil pressuress? maybe one is water), a larger rev counter and a clock. there is no speedo but we'll come to that They also have various warning lights spread out over them.  Anyone got any other ideas for cool dials? not really interested in the £30 "MULTI FUNCTION NEED FOR SPEED 11000000RPM" jobbies on ebay, am interested in round dials from old cars that maybe have a couple of different gauges in. it's aircooled so don't need water temp though oooh, and whilst i'm here - speedo requirements for MoT. Am I right in thinking you can pass without one? And anyone got any experience of hooking up an electronic pushbike speedo to a car? my guess is it just needs the wheel diameter set and a magnet stuck onto the end of the speedo drive cable but i don't know if they're calibrated to car speeds. sorry for the ramble... cheers |

Yea, you don't need a working speedo for the MOT - I went through a few without one ;D
The bike speedo's really don't work well on cars, from what I've seen - Demontweeks sell digital ones but they cost some....

Guess I'd need an odo for limited mileage insurance and the occasional working out of mpg, but that can be tucked up behind the dash. The problem is with the speedo the cable has been swapped for a short one that only reaches to under the dash, where the dial used to be. so it's pull the front hub apart to fit a new one, or fit some kind of electronic one instead. it'd be nice to know how fast i'm blatting through speed cameras i guess.

I have heard of people fitting push bike speedos to cars before. You could mount it to any rotating part after the gearbox and set it up however you wanted. Propshaft might be a good bet as its easy to keep out of the way, if you got a wireless type.
There are some similar types for sale for around £70 (I think) in PPC might be worth a look as they are car specific.

Pillock, speedo cables are not that tough to fit - although I did mine when sorting out the front brakes, basically: - Remove hubcap so you can see the little square thingy (passengerside front wheel)
- Remove circlip - put in hubcap so you don't lose it just in case
- Carefully pull out the old cable from the passenger seat
- Push the new cable in from the back of the spindle with plenty of grease - there is a shaft all the way through from the back - just make sure you get it the right way past the flexi hose
On a seperate note, good idea for a thread. Does anyone know if oil temp senders are universal (i.e. would a VDO sender run a Autometer gauge and vice-versa). Ditto for pressure senders/gauges Also, pillock, have you considered extra gauges in the fresh air vents? Thats where mine will probably end up... |

Bike speedos work very well attualy! I'm using one on the mini to good effect and i know several guys with turbo minis are using them too. Not do you get speed info you get data logging and a clock for under £20 and a couple of hours work. The sensor can go on a wheel or a durm or even on the driveshaft (like mine) then just key in your wheel circumfrance and you get a very accurate measurement.
The only downside i can see is the lack of a backlight for night driving.

i was gonna ask about this, slater, what one are you using? I'm gonna need one as theres no way that 13" wheels, a vauxhall axle, and a suzuki gearbox will ever give an accurate reading without masses of hassle!

Backlight is zero problem at all.... I know where i can lay my hands on some electroluminescent sheet complete with the inverter to power it Was thinking of I get a large enough tacho with a plain face, and it's cheap enough to mess with, then i could cut a square hole into it and mount the bike speedo inside. Did see that most of the bike units have a data logger thing, looks quite useful. Would also be a useable odometer as long as it has a battery backup and won't clear itself whenever i disconnect the main battery. Panda Matt.... the fresh air vents is a pretty good idea, not thought of those! only downside on a t3 is that they sort of point downwards, and also I was hoping to use them for fresh air! want most of the dash to be as stock looking as possible, even the heating and controls. will have to work out some kind of electric heater though as it's got j-tubes already fitted. anyway, anyone got any clue on the size differences between T3 and 911 clocks? Sure two of the T3s are standard 52mm but no idea on the 911 ones. Glad the bike speedos have been used to good effect though, a rev counter is a much more important dial to have right in front of you! Even though i'd not risk taking my engine over 4000rpm and most of them are redlined at double that |

IIRC the one i have is a sigma 1200, odometer, clock, average speed, cycle time (how long you have been driving), top speed, stop watch and some other biker stuff i don't relly understand. Its got two wacking great buttons on it to cycle the modes and stuff and is quite easy to change on the move.
I was reccomended the sigma ones by a guy running one in a kit car as he reckond they had got it to read up to 180mph (artificialy! got mine to read 150ish by strapping a magnet on drill chuck and holding the pickup close when the drill was running a couple of 1000 rpm )
Theres loads of differant models, some wire'd some wireless. Mines got a wire as i wasnt sure if the wireless would work though the car body but I'm told it will. Theres a little holder that you stick on your dash and then the unit clips in. They use there own little lithium battery like a watch. I'm not sure how long it will last but i guess it depends on how many miles you do as the unit switches it self off after a min or so of reading 0mph. Not sure if they loose data if you change the battery but i think there might be an option to program in the odo reading when you go through the setup procedure to change the wheel size etc. So you could program in the cars current milage too!
The pickup is just a magnet and reed switch, stick the magnet on something rotating and then the switch unit goes on a fixed bit. You have to be careful to get the pickup orentated with the poles of the magnet or it wont work! (just visulise how it would go on bike or try it!) They take a bit of 'modification' cous they are obviously intended for bike use but its not too hard to work it out, if it comes down to it you could just order a new switch from rs or someone and build your own pickup. The unit only counts pulses.

I've also decided to go for one of those, due to the nice clean design (in case it can't be mounted inside the tacho). However I'll let you win that one and bid on my own  |
