mk1 tacho options

[Volksee77]

anyone know of an aftermarket or other vw model 8000 rpm tacho that will bolt into a std GLS dash cluster, not looking for a monster tach or anything stupid like that to bolt onto the dash, want to upgrade the factory cluster for a stock look

[roccodingo]

will need a tach out of a 16V cluster... have some here will check for ya.

Sorry bud. out of the 8 mk2 clusters I only have 1 x 16 V set up, thats for the brown scirocco unfortunately.

Im sure i saw an old school VDO Tach at autobarn, it might have been about 3-4". Would the be the go?
I think it was something like this

You could always draw on an 8

I was reading vortex once and someone had a porsche one that went to 10K!

yeah all good ideas but i want a stock looking unit to mount up behind the dash cluster and work with the existing factory circuit board, the 16V unit i think will be very complicated to get to work as the foil backing circuits are completely different (already have one) and the porsche units are much bigger than the Golf mk1 unit, sigh i may have to bite the bullet an build a carbon dash with a Racepak LED instrument cluster like this intergrated into it,



Am hoping to not have to go down this path though because i like the old school 70's look of the stock cluster

Stock tachos are good for about 14K. There's a label on the back of them that says either 11 K or 14 K rpm.

8000 RPM gets the needle into the fuel gauge area though. Maybe you could make up an new face without the fuel gauge and extend the graduations.

Another option is the Porsche 924 tacho setup.

anyone what wire is for the sensor on the standard golf tacho? my loom has been hacked and need to trace it back to find the wire to sensor so i can connect it back to coil.

I dig this. I assume you're a crafty guy.

After building the new engine which sees 8500~9000 the old 7000 tach was rather useless. So here is my approach to solving this issue and still retaining an oldskool/OE look.

Basically retrofitted the guts from a generic 10000 rpm tach, scanned and photo shopped a new face plate, got the fine people at Kinko's to print in on a label paper and put it all together.

The bottom part of the tachometer case has to be trimmed as the after market tach is slightly larger


By pure luck the hight of the new assebly is same as OE and so is the needle shaft so the OE needle fits directly on to the new mechanism. You may have also notices that the circuit board now sits outside the cluster. Is is much larger so there is no room to hide it inside



Here is a pic of the original face and my printed one

That is pretty cool!

Hey i have pulled the standard mk1 dash out and replaced it with a mk2 dash, all aftermarket gauges this includes new sensors on the motor but i have now installed a Porche 911 Revs (sourced from Canberra VW (does go to 10,000 RPM), autobach black old school water temp, fuel, oil temp, fuel and orginal mk1 speedo - i have then fitted a led light set into the whole lot (if they didint have lights already built in). I have also whole sawed the excact holes and a mouting plate (made of aluminumn) and mounted it too the mk 2 dash - it looks the part but has taken a lot of work. Will take a photo and post shortly..

I'm looking at running a dual zone 9k Autometer tacho in the Mk1 instrument cluster.. I have a few busted instrument clusters so Timmy and I are going to hack a busted one up first to work out how to make it fit and then go to town on the one we're going to use when we work it out..

I have seen Porsche 924 instruments used.. But i'm not sure about the technical bits on that one.

[Volksee77]

Thats the stuff i was looking for, i may how ever reprint the face plate and alter the input sensors with a rectfier to get it to work with the standard range of movement and read correctly to 9000 rpm (my engines ignition hard cut)
