General performance figures for>

woh woh woh!

Unowithout cat)
118 bhp standard (although many websites quote lower for the 1.3 - 105BHP)
According to what I can find: 845/925 kg (mark1/mark2)

Polo G40:
133BHP
770kg

As standard that's a lot more power for a lot less mass.....

LOL i just read those performance figures and realised that i got my performance figures mixed up with the 1.3 polo GT LOL (silly me) but even still the Uno Turbo is a far more tuneable car than the G40.

Paul's correct with those figures. I also disagree about an Uno being more tunable. I'd say it's about the same, both are forced induction after all. VW's tend to be stronger engines as well, but that's a different argument.

From the mods I can remember:

decat, stainless steel exhaust
bored out charger (JabbaSport R1 or something)
smaller charger pulley
twin induction kits
port & polished
high-lift camshaft
ECU remap
wheels/suspension/body trims etc.

The ECU and twin induction's on their own increased power up nearly 50%.

It's about 200bhp per ton in total.

And front wheel drive!

I'll race him in the wet! Lol JK

 

[whatoncewas]

LOL, that's right. I has been known to even wheel spin in 3rd!

 

[jamie86]

Had my cinq wheel spinning in 1st and 2nd.lol and thats only 54bhp

Anyway back on topic I guess!

 

[F R O S T Y]

200bhp...Whoa! sounds like a beast mate! My uno also wheelspins in 3rd gear as does my mates r5 GTT. Has ur mate done a quarter mile in his polo? I reckon 14 seconds easy or even less. Dunc how fast did u do ur quarter mile at santa pod mate?

[Dunc Uno Turbo]

last time it ran pod it did a 14.6 with no fmic, standard turbo and a few other standard bits. should be quicker now by quite a bit i'd have thought! depends on the start i get.

whats does your do frosty?

pulling it to bits next year anyway to tidy it up and get ready for 230+ bhp

Dunc

 

[F R O S T Y]

I havent done a quarter mile run yet mate. What do you reckon, its pretty much standard as far as engine mods go, only got full zorst, induction kit, bleed valve and Dump valve. But saying that its a lot quicker than it should be i've been told. Theres only one way to find out i guess...Whos up for a trip to the pod

F R O S T Y

 

[Dunc Uno Turbo]

sounds pretty much like my mates old one mod wise and that ran a 15.3 ( i think or 15.5) and that was running quick for saying what had been done

Pod? i'm there hehe

Dunc

 

[jamie86]

When is the next Pod run?

I'll be up for that......

 

[whatoncewas]

Nah, never done any official times or anything. I predit 0-100 of under 14 seconds - it leaves his other car (Civic Type-R) 3-4 car lengths.

I've just came across this thread & have had a good read through it some good stuff in there, but, bleed valves, thats the biggest no-no ever conceived on this planet when it comes to turbo cars, unless you want it to go boom! Its very crude & if any tuner worth their salt recommends one do a runner.

As for comparisons, its a tough one. I ran 5 GT Turbo's for many years and my last one had 188bhp & 212lbs/ft of torque and had it times over the 1/4 mile in the high 14's which is quick. It was done properly & proved to be faultless over the 3 years I ran it as I never broke down, my mate in London has now owned it for 2 faultless years as well. I did consider an UNO at one time but in the end didn't go for it after driving about 4 different ones, this was 6 years ago.

The UNO is a good car, but there just isn't the depth of knowledge of tuners out there & therefore any well tuned 5 will easily outrun it. I know of at least 20 5 turbo's in the UK that are now running mid 12's 1/4s & one that runs high 11's & its a daily driver car with 150,000miles on it (he did 12 runs in one day at Santa Pod, slowest being 12.3). Plus the one area where there is no shadow of a doubt is the chassis, the UNO engine may take more, & to be honest is probably a better unit than the Renault, but the chassis even in standard form, feels on the edge where as the Renault copes well with upto 200bhp, got to remember Renault where the last manufacturer to win a full WRC event (the Monte Carlo Rally) with a FWD car in the 11 turbo back in 84 which has same running gear ad the 5.

The Polo G40 really can't be mentioned in the same thread as either an UNO or a 5 because it is limited by having a supercharger & there is a very long thread on the topic of the merits of each in the Cinq section, & it has the worst chassis of the lot, it is truly one of the worst handling cars I've ever been in, & it has even less of a knowledge bass than the UNO.

So if your talking about tuning the car the 5's teh best, if you want to keep a car standard in A+ condition for shows etc & rareity value, I woudl plump for the UNO as I think it's an often overlooked design classic of the 2 box design.

Again these are all just my opinion based on my experience, don't take it as anything other than that

 

[Dunc Uno Turbo]

good reply that evo mate and your very very true about the tuning, but in a way i like the though of owning a really quick uno, and not a really quick 5 as there are alot around as you said, plus the 5 turbo engine isn't anywhere near as good for track day use due to the rev range on it (doesn't rev high enough) and they run out of puff out at 120mph.

but don't get me wrong, i do really like them and would have one (but still keep uno) just preffer the exclusivity of the uno

but one totally good bonus with the uno is the engine design is more modern with fuel injection and no manual choke which used to hack me off with my old renault 5 gt turbo powered clio hehe

[F R O S T Y]

Yeh theres some good points you made there J333EVO but regards to the bleed valve i do agree to some extent about what you're saying as in it can result in a boom but an UNO TURBO was designed to run 1 bar of boost in the first place as standard however fiat decided that 0.6 bar was enough boost. (maybe for Grannies) So as long as the boost does not exceed 1 bar it should be safe to turn the boost up. I know people with 300bhp unos that run 2.5 bar boost safely all day long. And lastly with regards to the Renault 5 yes you are correct it is a lot easier to find tuners for them as they are a lot more common than unos and hence have a lot more off the shelf parts for modifications etc. But like Dunc says what we love about our UTs is the fact that they are a rare classic and as much as i love 5 Turbos (My best mates had 3) the manual choke does **** me off too! lol But other than that its a great little beast of a car!
And Dunc me old mate....Whats that u say?? A Clio with a 5 Turbo engine? Sounds kool mate!!!

F R O S T Y

 

[Dunc Uno Turbo]

yeah, a clio with a r5 gtt engine, looked like a 1.2 but went like stink (well for about 27 miles in the year that i owned it cos i kept blowing it up and it was always at the garage lol) needed a respray too but open the bonnet and a **** load of samcos hit you in the face lol

Dunc

 

[jamie86]

J333EVO- Why such a no to bleed valves?

Maybe you can explain to me sunday as my little Y10 runs v.well with one fitted......

Quite a few bhp up on standard!

 

[Dunc Uno Turbo]

boost spikes and the temptation to turn it up just that little bit more

Dunc

 

[J333EVO]

Some good replies there. Your right about the UNO engine being newer & being designed for 1Bar boost all engines are tested above what they are sold with thats how they get the reliability, test it higher, fix the problems therefore setting it lower in builds a safety margin, but the Renault engine was designed to go to nearer 2Bar in the 11 Rallye cars and the Mid engined 5 which could be bought with Renaults own performance pack giving it 260bhp 270lbs/ft or torque & its believed that 50% of all mid engined 5's were sold like this, but thats a very diff car. The reason Fiat never sold it like this was the chassis as I said, it really struggles to cope. You have to remember whenever a car is realised to the public it has to be a compromise to meet the needs of the masses not the individual, thats why people like us buy older cars and modify because we are taking a good basis but tailor it for our needs.

I've always fancied an Uno Turbo but just never came across a good'un whenever I was looking for a car, there was v.few of them in Scotland as I've only lived down here for 2years.

There are much better & more reliable ways of getting more boost than a bleed valve which is probably the single biggest reason that all turbo cars have a bad rep for reliability. Reprogramming the ECU, bigger injectors re-jetted carb, stronger waste gate, you see the problem with them is it tricks the waste gate into staying closed longer than it should, therefore the ECU doesn't know what is happening & can lead to detonation from fuel starvation as there is insufficient fuel for the higher boost levels.

& fuel injection is available on the 5, on my 5 I never needed the choke because it was so well set up, so I removed it as it gives a cleaner input for the fuel without the butterfly in the way. http://www.bbperformancetuning.co.uk/articles/article.asp?id=52

And to be honest il driven a good few tracks in the UK & there is never the opportunity to get much above about 100 which means its an ideal track day weapon, so the fact that the gearbox ratios hinder it to about 130mph is neither here nor there. Try keeping up with a well driven standard Elise round a track which tops out at 120 and you'll see what I mean.

& why bother with putting a 5 engine in a Clio when you can have this http://www.bbperformancetuning.co.uk/articles/article.asp?id=31
Looks like fun as the 172 has a great chassis.
