Cup240
Does anyone else do a kit for my 172 apart from ktec? I dont want to go down the turbo route, prefeer better low end torque. Thanks

big boost cup
Buy the supercharger bracket from @marinemackay2003
And have a browse on here for the rest of the parts

Sorry should have mentioned im unable to do this myself, my knowledge starts and stops with bodywork so id have have a specialist do it
It's a fairly simple conversion to do your self tbh will pm you

I've been following your project thread, surely it's no that simple...
I'm guessing GEN90, your bracket & Charger and you're on your way?
Cam belt change to fit the megane crank pulley, megane injectors, can map it on standard ecu, remove aircon and fit cup alt bracket and my s/c brackets, charger and intercooler that's about it in simple terms
Yes the pic is my charger build @barnesautos

yes you need to ditch the air conditioning as that is where the charger sits

I already have the aircon deleted and also have epas steering so plenty room. Why does the charger attatch to the alternator belt? Does it not force air like a turbo? Also is it a must to change the valves like you did or was that just for reliability? Thanks
Sounds so simple!
Everything sounds simple, depends on how mechanically adept you are tbh
@notfastnotfurious do you have the pms aircon delete? If so you would need to convert back as the s/c can not be run on the pms kit did to belt width
The charger runs from the crank and is run off the aux belt drive as it replaces the air con pump in location
As it's a belt driven turbo in effect so requires a belt to drive it unlike a turbo that runs on exhaust gas
As for the valves they are Not required for low boost but would be a good upgrade as I had my head off at the time and running more boost it made sense

I dont know how to tell if its pms as it came like this. Its a proper cup model. Are dump valves available? Heard a rumour its possible.

It's so simple it's silly.
Remove engine, take it to gave Cambelt done and key way pulley fitted.
Get engine back, add bracket, add supercharger.
Put engine back in, plumb in boost pipe work and supercharger oil cooler
Get mapped
I did mine start to finish including painting the engine bay, wiring in a different ECU and driving 3 hours to get Cambelt done in about 30 hours.

This.
It's simple for someone like me or you, but not sure it's something the average DIY home mechanic should take on, or the op by the sound of things.
Yes maybe you could do it in a weekend or something if you had done it before. But when I charged mine for the first time and I factor in all the research time, checking pulley sizes, air flow rates, restrictor sizes etc etc. As well as getting everything installed neat and tidy and not looking like it was just thrown together it took weeks!

most of the hard work will be done already with the kit tbh, pulley sizes are either 85mm or 90mm depending on whats required, my kit takes care of all the belts and pulley side of things
looking at making some restrictor's in various sizes too
most of the hard work will be covered

If my R3 engine goes pop or doesn't impress I'll be in touch for one of your kits mate. :up:
You can also play around with pulley sizes and restrictors to tailor the boost and power band. I used a 95mm pulley on mine as I wanted the boost and power nice and low and further up the rev range as this was better for the racing.
The brackets look well made mate, I would have had some myself if they had used an auto-tensioner.

You still could do tbh. Just take the turbo off and run the charger instead. You'll be able to run more boost as your on low comp anyway aren't you?
Andys medium boost build, megane internals etc 280hp.
Its currently in getting repaired as the cam seal popped out causing a massive oil leak, so it needs stripping and checking for repairs, once its fixed its going up for sale I think.
If its got megane piston's that means the vvt will have been disconnected. Not a problem with a turbo setup as you can dial in some boost to compensate. Not so easy with a charger though.

I'd love a supercharger...
It sounds less hassle..

It is the less hassle route.
The only real downside compared to a turbo in terms of reliability is the charger will let go at some point, and compared to the Turbo you can't rebuild them. So another Rotrex is about £700 - £1k.
Oh, and less torque. But i'm more than happy with my 250bhp and 220 lb ft. Doesn't exactly feel slow. Lol!

It doesn't break gearboxes either. Well not as much as a turbo conversion does! :wink:

Seems a shame to sell it, but I'm sure you'll make the decision that's right for you.

Totally... A new charger would seem a pita,but being a sealed (they're sealed right?) unit I would expect there life span to be long and uninterrupted.
I've been around turbos a long time and something just loves to kill them and no matter how hard people try they just bite the dust..

Yep, they are sealed. I don't want to tempt fate by saying mine is all fine and dandy 😂
My last project was a 205 GTi6, swapping the engine, building the loom, etc.
Took 3 days plus a few hours to mate the loom.
Sadly, with kids, spending hours in the garage is now an hour here & there so this kind of project would take months!
I think the reason they fail is over speeding, and possibly straying over the max temps of the oil
Can't remember anyone monitoring the oil temps for the charger on the clio's

Max rpm is roughly 7300rpm on the 85 mm pulley btw
That's pretty much bang on matey.
Technically you would be very slightly overspeeding the charger at 7300rpm with an 85mm pulley. But if you talk to rotrex off the record the C30 range can run overspeed by about 10% with no issues.
I ran mine to 7600rpm a few times. But I'd never have a rotrex again.
