Gauges

[new to this]

Has any one fitted 4 small gauges in a Sprint dash ? is there enough room ? or would a Stag dash fit ?

Depending on what gauges you need.

All I had extra on the V8Sprint was an Oil Pressure/Temperature in place of the clock.

Not needed much else.

You can fit a fourth small gauge below the fuel gauge but you will need to remove one of the lugs which hold the air vent in place and Dremel a small bit of metal from the dash. You will need to counterbore the hole if you want it to compliment the other gauges but I didn't so the gauge just sat slightly proud.

Okay thanks, tired a Stag dash but to small for opening

Probably not much use to you, but it may stir ideas, and its huge amount of work, with my Toledo, and the seating position I have to adopt, of all the 4 auxiliary gauges fitted, there is only one I dont have to wriggle around to see clearly, so, I started playing BIGTIME with the opportune purchase of a plank dash I started playing with ideas,












6 idiot lights too, L & R indicators top outer, Oil, mid left, "Shift Light" mid right, bottom 2 will be beam and ignition

Oh I really like the 3 hole plank dash! That really cool.

I didn’t want to cut the plank so fitted a motorbike gauge (Koso TNT04) and made a custom panel for lights. Both fit inside gutted speedos in the standard holes.

Koso does tach, speed, mileage, temp, volts, indicators, high beam has some idiot lights.

Light panel is a first draft, I’m going to revise it (in black). Could be revised with a oil pressure gauge too, which I may do.

Just thought I would post this up, still nowhere near finished yet, but its getting there.......

I thought 100 mph was over-optimistic for a factory-standard Triumph Toledo 1300 speedometer, but 170 mph as indicated by your after-market accessory speedometer would be unatainable!

Even downhill with a following wind, a Triumph Toledo 1300 would struggle to reach 80 mph!

You are underestimating these cars. Well, the 100mph. 170 would need a vast amount of power.
I have sat at 100mph or a tad over in a Toledo fitted with a better cam and raised CR, but otherwise standard. It did have overdrive, and a 4.11 diff. And that speed was via GPS so accurate. No reason a 1300 could not achieve that or indeed more.

On which off-road race track was that, given that 70 mph is the ABSOLUTE maximum speed limit in Great Britain on the public highways - motorways & dual-carriageways, whilst 110 km/h or 130 km/h (circa 82 mph) are the ABSOLUTE maximum speed limits in many European countries!?!

An engine with a substituted alternative camshaft with increased duration & lift, plus increased compression ratio, could hardly be regarded as factory-standard!

A factory-standard, VW 411/412LE engine [VW Type 4 style air-cooled engine with 1679 cm³ displacement & 8•2:1 compression ratio | 80 DIN hp @ 4900 rpm] develops much more torque & power than a VW 1700 Type 2 engine [VW Type 4 style air-cooled engine with 1679 cm³ displacement & 7•3:1 compression ratio | 66 DIN hp @ 4800 rpm].

You (of all people) shouldn't confuse a man made speed limit with a law of physics Nigel. Not everyone drives like you. I can think of many places in the UK and many more in Europe where speeds of over 100mph are legally obtainable.

From my own experiments on the Carledo, it would seem that an average powered (125-150bhp) modified Dolomite shaped car (or stock Sprint) achieves an aerodynamically limited V-max of around 115-120 mph.

So at 100mph+ an extra 5mph on you V-max costs 25bhp. But the NEXT 5mph probably costs 50BHP and the 5mph after THAT costs 100bhp. That's the nature of aero and you soon fall foul of the law of diminishing returns. To the point where I no longer consider a car's V-max as a viable, or even interesting, datum. Fast enough to lose your licence is more than fast enough, I'm more interested in economical, long duration cruising speed at or slightly over NSL. Which MAY give a possible V-max well over 100mph, but that isn't the point, it's just a side effect!

So yes, a 170mph speedo is a bit optimistic to say the least. But it's a sad fact that a 170mph (or 180mph like mine in the Dolomega) electronic speedo of the sort favoured by transplanters, is cheaper and easier to obtain than one which reaches a more achievable/realistic V-max of 130-140mph. So the 170 speedo isn't a fad or a boast, it's just the pricing structure of the instruments!

One final point, the factory standard Dolomite Sprint speedo reads to 140mph, a figure just as unattainable for it as 170 is to Ian's near 200BHP Redtop powered Toledo! I'm not sure it still applies, but there was a law in the USA from the mid 70s on, that American market cars could not possess a speedo that went to more than 85MPH! What the point was, I have no idea, but nearly every car built, even in those low-power-from-high-capacity days (I had an 80s built 5 litre V8 Oldsmobile that only made 140 bhp) could cruise "off the clock" all day and the night after!

If you remove the propshaft from a Sprint you can run it at speeds which register off the clock!

1. None of your business, but I will say I had our spitfire up to 208kmh perfectly legally in June, on the way to slovenia. With the lady wife and a boot full of luggage... it would have done more, but the traffic was getting busy ahead. You need to think bigger about what these cars can achieve. And what you say about speed limits is incorrect, and Carledo is bang on about there being places within the UP and Europe where there are NO speed limits at all.
My Toledo was not a highly modified car at all, it made 91bhp on the rollers once set up. But as stated, it would sit at 100mph and that too was 4 up.... (we were running a bit late for an event)

You could probably do it on a rolling road with the drivetrain intact! Removing the wind resistance is key, it's the biggest source of drag at high speed! The car is geared to do more or less 70MPH at 3000 RPM in overdrive top, so therefore, without drag, it will do circa 140mph at a perfectly attainable 6000 RPM. Add in a bit of speedo optimism and you are well off the clock!
