General Whats Your Revs To Speed?

80mph generally equals about 4000 rpm, on a level road, at least it does on my car, then again i am running different wheels, an tyres 195/45/r15

these are 2 pics i took a long time ago.....please note, boost, good oil pressure, and warmed through oil and water......

i'd have to go with the negotiator on this one, can't see beyond a faulty, miswired rev counter, depressed clutch, or an outright fake. my personal opinion, you've got up to speed, then pressed the clutch, giving a slight drop in oil pressure, no boost, you've done it early after starting the car as neither oil or water are up to temp yet

Thats the standard oil pressure for it - if you like I can give you the same pic but on boost :) And the pic was taken after about 20mph of driving, the thermostat is stuffed so it doesn't warm up properly.

As I said though, I can give you a pic of it on boost :)

And my tyres are not standard :)

i got UT clocks fitted in my car, muzzie what does the rev counter say when your cars hitting the rev limiter?

EDIT: just took my car out and yeah, 2750rpm 5th gear at 60mph

Dunno - never taken it out that far, I've never gone above 5500 I wanna keep it reliable.

Came back from college today and checked the revs to speed ratio.

1986 Uno 45S, 999cc FIRE with 5 speed gearbox.

60mph = just under 3000 rpm in 5th gear.

Muzzie, by the sounds of it your tachometer is under reading!

Maybe so, but in the mind time I have you all wound up :p I have another test to confirm that though :) Aftermarket tach!
 
Yep, I'm with Chas and turboned on this one.
I think you're a FAKE Muzzie! :)

Interesting that you have a miles-per-hour speedometer in NZ, like I do. The other Uno Turbos that I have seen here have all had km/h speedos.

My Mk1 Uno Turbo has a Tipo-style gearbox (linkages inside the car) and there is very little gap between 4th and 5th. At 100km/h in 5th, it is doing 3000RPM - double yours. This is even with 185/60 13 tyres. So, I think you must have a very different Tipo gearbox fitted, or you were dipping the clutch. Besides, your second photo is different again which is not exactly adding credence to the readings ;) Nice odometer reading though!

Another interesting fact is that I can't maintain 100km/h without 0.3-0.4bar turbo boost. The fastest I can go without the turbo boost gauge registering is 80km/h. My Uno Turbo is super-economical and as you can guess, the turbocharger is very responsive because it's boosted-up most of the time! So, to take a photo at 100km/h with no turbo boost, the throttle would have to be fully closed - coasting, or in neutral...

Contrary to what someone said, I'd happily take you on in a race because if your gearing is that high in other gears, you'll be bogging down!

Yeah you're right, the tacho reads wrong :) I had fun while it lasted though :)

It does about 2700 at 100k. And I can get well over 100 without registering boost. Easy :)

And thats no fake :)
 
Good! mystery solved.lol


Mine 6500rpm (ish) at bout 135mph was getting blinded by the oil smoke from melted piston so may be a bit out... :eek:

If you are doing that speed, the rev counter is incorrect! Mk1 does 3200 rpm at 100k. Tyre size is irrelivant

Ive seen a few NZ new UTs with mph speedos mk1 and mk2, never a digital though.

So you're telling me that my GPS is wrong??

Because at 100k on the dot, my aftermarket one says I'm doing 2800.

And if you slap 20s on an uno (I know not possible but still) then you won't be doing 3200 at 100.......... NO WAY IN HELL!
