supercharging the Dynamique

[Martin_172]

managed to "aquire" a supercharger from a Cooper S and was just going to sell it but was thinking of supercharging my dynamique when i get my 172 next month as the dynamiques coming off the road.

now as far as im aware i would need the following to make this possible...

custom bracket to mount the supercharger
custom aux belt to run it (as well as the alternator)
custom pipes to run from the supercharger to a front mount intercooler then from there to the inlet manifold
bigger injectors?

would this need standalone management or could i run this on the standard ecu with just a remap

i dont mind doing the mechanical side of things so i wont be paying much if any labour charge so was thinking of doing it for a bit of cheap fun! especially after seeing a supercharged polo 1.4 in a magazine today lol

what else would be involoved?

Stock ECU can run it with a remap you need a 2 bar or so map sensor. A stand alone ECU has advanatges but it costs.

You need some bigger injecotrs realy as well there laod thought oc hoice form.

The plastic intake manaiofld usless though you need to fabricate a stronger one.

Spark plugs need to change them.

Idealy start with a 1.6 engine as the cooper S chargers for that sized engine If your going to all the effort you might as well just use the rad from a 1.6 one make the 1.2 ECU run the 1.6 with the charger mounts arn't an issue use the 1.2 box if you realy want the 1.6 is stronger though.

Need an air filter setup as well along with some presure release valves and also you want an intercooler for some proper gains. Else you'lll be significantly limited by boost on normal fuel. Ok so you can run aditives but might as well make the pipework for an intercooler and run stock fuel.

actually now that i think of it, this would need a new inlet manifold/throttle body as the standard manifold is shite and then cable throttle to go with it wouldnt it?

 

[Fred@BTM]

good luck trying to get that ecu to read boost! it can only just about read the std sensors as it is

Electric throttle body can be used.

The more I think of silly projects like this I always end up with a K20A engined Clio (CTR engine) then the charger etc that. BenR's the man about tunning that engine but its better than the Clio has a better 6 speed box LSD should be cheaper the imports have it as standard if you get one of those.

Or go do somehitng interesting like a 1.6 /dci powered 4x4 model using the 4x4 Kangoo setup Ok so its not wonderful disconecting at speed etc but I'm sure something can be done. Would make a true 4x4 Clio not just the poeple on her who say a car has a 4 x4 ride height.

so realisticly it would need standalone management?

what about going back a step in time and ditching injection for a set of motorbike carbs?!

dont want to spent any big ammount of money on this just fancy doing something stupid with the 1.2 engine since its a nice wee car thats lying about doing nothing!

Yes that a fun ideal bike engine t/b's on it.

Why not stick 2 engines in it?

 

[Martin_172]

ive got 2 1.2 16v engines actually lol 1 spare 1 fitted, but like i said im not wanting to spend much on this car just thought it would cost maby less than £500 to supercharge it (not inc mapping) just it seems like more hastle than its worth

 

[A13EX F Trophy No70]

need to lower the compression ratio too?

 

[Jamie]

Chasing a rainbow on this one, going to be endless money and on a 1.2? well that would be silly.

Save up and buy a quicker car or look for alternative methods imo.

ive got a spanking new turbo off a kangoo in the bottom of my box i keep staring at with a funny look every time i open it :lolup:
its got to be doable if you can bolt a turbo to a crappy 1.3 hcs ford engine and run it on standard management albeit at 5psi it must be doable fairly cheaply

Would help the 1.2 not that high though still will be a limitation.

If its a KKK turbo off the K9k is do don't go using that turbine will melt. Infact don't use any diesel turbo on a petrol.

if you read my original post you'll see im buying a 172, but i have my black dynamique sitting doing nothing as well as a supercharger sitting doing nothing and thought and still beleive it can be done cheaply, just not sure on the ecu side of things with these cars..

 

[16v_jon]

Why not give it a try, you can use megasquirt for the managment for cheapness, map it yourself using a laptop and a wideband.
The only thing you going to have to do it drop the compression of the engine, the plastic manifold will take 20 psi of boost i rekon.

 

[Matt@Stealthsport]

Why bother?

Just fit a bigger engine such as a 172/182 lump.

Easy job and will give you similar power I would imagine........

Seems pointless to re-invent the wheel if you know what I mean.

 

[Martin_172]

172 engines been done, no one as far as i know has supercharged the 1.2 16v.

i love how lightweight the car/ engine is, f**k i even lifted my new engine into the back of a van myself once the gearbox was removed!


imo my car has just enough power to have loads of fun down a backroad and it handles totally spot on and goes from 110-0 in no time due to s**t hot brakes and no weight! (As gibson found out when he was behind me in his 172 at 115 coming into a 30 when i was braking from 115-30 hard and he couldnt slow as quick as me! and hes got DS2500 pads (think thats the ones?))

it just lacks low down torque to pull it out bends so why not supercharge it? ive already got a reprofiled cam and lightned and ballanced bottom end to stick on it when i get the chance to build it up!

jon just reading into megasquirt and love the sound of it, obviously due to this being a project on the side id rather not spend thousands on a motec and having it maped! etc as it defeats the purpose of the build! you think 20psi is the maximum safe limit of boost or maximum it will take before it goes?!

id love to give it a go, im fine on doing straight swaps eg changing an engine for an identical one etc but just never tried anything custom like supercharging or mapping!

 

[leighk18]

do it mate sounds like a great idea /then see if you can out run ya 172 lol

 

[Martin_172]

lol wouldnt outrun it, well down a backroad it would outrun or atleast stay with a standard 172 (well not sure about mk1 172 never driven one!) straightline it wouldnt be that quick but would be fun!

anyone got any idea how much power it would run with arround 20psi of boost? how do you adjust the boost preasure of a supercharger is it by using different pulleys?!

where would i get a bracket and belt made for it? would i need to run it off the cambelt or aux belt?

 

[leighk18]

i belive you run it of the cambelt but could be wrong check these out as they deal with supercharging saxos,106s etc and they use to sell a plate which could hold the charger in place which charger do you have could you pm me some pics please intrested in the idea

no its run off a seperate belt from the crank pulley, boost is adjusted via pulley size and 20psi will require a big drop in compression and quite alot of strengthening /cooling mods

Run off the AUX belt easier that way. Easy for the belt just measure up the size you need with abracket for the charger and go to a motorfacotry and roder a belt that size etc.

20psi of boost forget it few normal chargers work that high you'd be looking at about 200hp though. More lily your looking at 10psi at most boost which would be near 130hp.

Don't forget you need a better gearbox realy the 1.2 one isn't that good strenght wise.

20psi is silly you'd need a serious charge cooler etc to cool it plus most likly water injection and lowered CR to make it work on any normal road fuel.

To put it in prespective I think Matt black old car could run up that high with its high spec turbo and that would make 500hp. But don't forget that a turbo engine build for a turbo with an expensive manifold stronger rods and lower CR pistons than the normal low CR pistons the stock engine ran.
