did i quick search but couldnt find anything with v8 in it. i remeber reading a thread about a bloke that done a build like this on here, he had the exhausts at the front but cant find it now, this looks a little like his.

The one on here was an Alfa V6, with conventional gearbox and rear mounted, while this looks to be the crappy old Rover V8 with some kind of chain drive front mounted. There's one with a Chevy V8 on there, too, but so far nothing with a Chrysler Hemi........

I appreciate that its been done, but it looks very little like a cinq anymore! Get a s'charger under the bonnoet of a 1.1/1.2/1.4 and then i'll be impressed

Was on my mental list a while back, but came to the realisation that a tub is the only way to go

I'm 95% sure a centrifugal blower will fit (although the rad might need moving). Blue 2 is slated for this when/if time and money allow.

I love the sound of a nice V8..music to my ears :worship:

I was musing about a supercharged FIRE engine in the Cinq yesterday......I love the power delivery from a Supercharger. But I think space would be a big problem.

Also which charger to use. Most conversions nowadays seem to use the Eaton Charger from the Mini Cooper S's. I have a feeling these might be a little large for a 1.1 or 1.2 8v but would prolly well suit a 1.4 16v.

Anyway I fanyone undertakes the conversion I will be incredibly interested.......*goes off to research*

An eaton in Punto has been done by davethetrike. It went bang, but what the hell. 16 valve engine, so when the crank pulley sheared its keyway the engine ate itself.

Like I say, I can't see an Eaton fitting a Cinq for space reasons. But I'm pretty sure a Rotrax centrifugal blower can be squeezed in.

Yes,the lot went on ebay a few months back, so all that had it on your list of 'things to do' you missed your chance.

Surely abit of 'bodywork' and a bonnet bulge will sort out clearance issues

I spent a lot of time reading dave's thread....it was fantastic! I also read it with views to s'charge the 1.2 16v... but taking the same approach as dave took on a cento is a no go.

There's no room up front, above, or even enought room to fit an additional belt on the pulley, at least with a 16v engine in there. It may be easier with an 8v, and I'm sure it CAN be done, but its goona take a LOT of planning

But the Rotrex is tiny but perfectly formed :yum:. You'd use the alternator belt (but a bigger one, with an idler pulley) and work out some way of preventing the crank pulley from coming loose.

OK, it'd not have the bungee cord effect of the Eaton, but would stress the drive train out less and have fewer of the control issues posed by turbos.

yeah, looks nice even the 7 or 8 poly belt is gonna be double the with of the current alternator belt and is gonna need either;

the engine to the shifted towards gearbox end at least 2-3cm if sharing the same belt for the alt....even greater if using independant pulleys.
or
possibly a custom offside engine mount (maybe the euro sei latest design may work if you can fit it to an older cinq/sei chasis)
or
cutting a section out of the inner arch

these are all observation with the 16v .. i really need to get a 1.1 8v just to get a grip on a normal cento lol

your also gonna need an oil cooler....inlet oil temp 80 degrees max isn't much, especially with that load.

I think if you could take drive from the other end it would be easier, perhaps some kind of drive from the flywheel end, but that may be difficult as well.

Would love to see it done though .. i have reigned myself to a future turbo conversion though...far easier.

Gear drive from the ring-gear on the flywheel

Just use the Air-conditioning type setup.
I'd expect an A/C compressor puts more load on the system than a blower would.

@brooky - yeah, its that easy lol why didn't i think of it. The gearing will be totally wrong, you'll need to cut the geabox casing, make some mounts, and get the tolerance just right.

@cc1 - that was a plan on the 1.4, but the whole AC mounting had to be junked, as it used the sei engine mounts point lol.
O
n the 1.1 though i'm sure it could be done with the ac mount. Only concern, even on the AC version, the belt is still only a 5V, no where near the rotex 7V/8V. Not sure is it due to additional load or what though.

It just created a whole new list of 'things to do', it came out of the left field for me And yeah, it is big, luckily I have no space issues but a bit of a shuffle would be required for a Cinq.

Yes. that should work, but I've never seen one in the flesh. AFAIK, the Rotrex doesn't usually need an oil cooler.

Think of it as a belt driven turbo without all the exhaust and temperature control hastles.

The Rotrex uses a planetary gearbox to get the spin up speed so would produce some start up resistance.

Unless my skim read of your linked document was far to much of a skim read, it does have an oil feed...hence my 80 degree max oil input temp, i didn't make it up lol

Still and oil cooler would prob be fitted to such a beast anyway, so you could just take a feed off t, as long as it was post filter.

Kristian

Nope -- it has it's own oil supply: uses stuff of a similar spec to jet engines. So the port they refer to is the inlet port of the supercharger, rather than the inlet port of the engine's oil pump. Run these on engine oil and they won't last ten minutes.

fair enough Like I said it was a skim read - will have a proper read tomo
