General max speed of Uno Turbo MK1 1.3

[kpematop]

Hello, what is the max speed of Uno Turbo 1.3 MK1
I reach 200km/h, but more the car don't want...
I have forge atmo dump valve and BMC air filter. And the turbo works at 0.9bar

i thought it was around 127-130??

gotta love the uno's

Divide 200 km/h with 1.66666666etc. and you'll get about 120 mph.

200 km/h is maybe the the topspeed for a close to original uno, but if you raise the boost and get rid of the rpm limit (6700rpm) You will make a lot more..

I am with FORGE MOTORSPORT ATMO DUMP VALVE
BMC F1 AIR FILTER double cone
boost at 0.9bar
but more 200km/h don't want((
I AM SICK
I want tear asses of GOLF 2 GTI and BMW 320 E30 on max speed))

Just out of curiosity, how many rpms are you doing at 200 km/h? How much boost is your turbo producing at that speed at full throttle?

Note that the mk1 Uno was never a good friend of the wind tunnel, which can be easily seen by noticing the brick-like (but very solid looking and overall appealing IMHO) shape so why don't you go with the cars natural characteristics and take advantage of its superb sprinting ability instead of trying to get it to do what he wasn't projected to do in the 1st place?

If you insist on trying to make it go faster, I don't really know how tall is the standard gearing, but I'm almost sure that at those speeds you're already on the descending part of your engines power curve, so you either start thinking about making it breathe better on the higher revs (hybrid turbo, head work, cams...) or try to find a compatible gearbox with taller ratios.

Oh, and I don't think I should comment the "ass tearing" issue

0.9bar on 5 gear

i have taken my mk2 to 255kph ..@ 7300rpm

The mk1 Uno shape WAS designed with the help of a wind tunnel. It has a drag coefficent (CD) of 0.34 (round about), which was the LOWEST in its class at the time of the launch in 1983!

The mk2 Uno was slightly more aerodynamic, but not by much. I think they got it down to 0.33 with the redesigned front and the tailgate.

It was the low drag CD that enabled the Uno to achieve good fuel economy and good performance from not much power.

Don't forget as well with aerodynamics, it's often the shape that doesn't look like it will work that is the best. I remember how it was often stated in physics that a bullet from a gun would actually travel faster if it went backwards.

However, the mk1 Uno has such a cool 'chunky' shape

You have 2 problems. The engine simply does not have enough power. And, the faster you go in 5th gear the less power the engine is making as its it reving well above its peak power point.

you need an engine that can make more torque at the higher RPM you need to go faster.

 

[Muzzie]

Couple things I've noticed.

My Uno only does like .6-.07 bar - I've had it up to 210 (just).

So i would have thought the one afore mentioned would get more than 200 running extra boost.

And the other thing, someone said something about an RPM limit?? As in a rev limiter. Do Mrk1s have this. Cause mines completely untouched, but I've had it out to almost 8K on more than one occasion.

Which brings a further question - what will they do happily without blowing up?

 

[SteveNZ]

Mk1 turbos dont have rev limiters in NZ.

7K is ok. If you rev it more it probably wont blow up but its going to be stressing the engine a whole lot more. i.e. less reliability.

Standard Uno turbo will do 200K. A few extra mods, more boost etc will still only get you around 200k. But it will get you there faster.

Problem is matching the power of the engine to the gear ratios. You could have 200BHP at 4000RPM but you may still only do 200K top speed as all the power is gone at 6000. Its very difficult to get an Uno to make good power at high 6000+ RPM.

Pity I don't have a gearbox that helps me get there faster Stupid sync on third is totally non existant. Right royal pain in the backside, and I don't like letting anyone drive it because of that, they crunch and grind it badly. Actually, I hate anyone driving it regardless, but thats especially more so.

And its good to know I won't blow it up lol. I'll just keep the oil changes up and she'll be right.

Duh! :bang:

just thought i would tell you guys, that the uno turbo was designed to run 1.0 bar as standard but the boost was turned down over hear because of insurance problems. italian uno's run 1.0 bar standard. the bottom end is just about bullet proof. mk 1 gearboxes are not. they are weak. mk2 tipo type box much stronger. with 1.0 bar, the uno can push over 130mph given enough room. with 0.86 bar[uk spec], they top 125mph. with a few easy tweaks, the engine makes 1.0 bar btw, did you know the turbo has more ground clearance then an ordinary uno

 

[jamie86]

I had an indicated 140ish on my MK2 so unless the speedo was stupidly out..

Also that was on 15" wheels...

Would of GPS'd it but was a bit busy melting a piston :yum:

Over where? I doubt thats any more than a rumor. I've heard lots of others too
