ive had a few problems with my rotrex c30 supercharger so ive trawling the internet lately for advice.
but then checking www.rotrex.com i seen this important update-

March 2012

Due to lack of availability Rotrex has had to change the high speed spindle seal in the C8 and C15 families of superchargers from March 2012.

As a result of this new seal the supercharger must now be positioned above the canister and oil cooler in order to prevent any potential oil leakage from the supercharger. If the canister or oil cooler is placed too high - thereby allowing the supercharger to fill up with oil - the oil will leak out through the seal and into the compressor housing. For the avoidance of doubt the supercharger is designed to suck oil into the supercharger when running, and it will function perfectly well with the canister and oil cooler positioned below the supercharger.

In addition to being available the new seal has many other benefits including less wear and longer durability. The new requirement for the oil circuit layout has no effect on the functioning of the supercharger when running.

We foresee a similar change in the future for the C30 and C38 families of superchargers, however at this point no decision has been taken. Nevertheless it is always best to position the supercharger above the canister and oil cooler to avoid any risk of leakage in case of wear or damage to the high speed spindle seal.

this is the bit that concerns me as the supercharger is extremely low as it is but now i supposedly need to get the canister lower!
its just not possible :/

thats ok with me as my charger is on my top of the enginer and the canister and cooler is low

albeit mine is on a pug

what charger you got?

mine runs a c30-94

what sort of power you running?

[mikemcc03]

hi,
to be honest all i know is its a c30 charger.
it was advertised as 280bhp but it isnt that but luckily i had it cheap enough but now i have problems with the charger :/ it ran 212 a few days ago an the guy at gotboost said it sounds loud. soooooo
leaking from the impeller shaft (who'd of thought that would happen)
so i think with the force of the induction its managed to get some kind of ingress into the charger an damaged the bearings and put a very faint mark on the rollers.
hope fully soon be rebuilt an see what happens then.

Lose the aircon pump & mount the charger higher up the block

[andy888]

get some pics up of the car bud. sounds a hoot! when did you get it?

Lad at my work has one with the jam sport kit and charger failed sent it away and got no support from jamsport or rotrex , it's a expensive kit to get about 13k miles out its just a normal st now

hi carlo to be honest the charger isnt that complicated inside at all my charger started to whine an was way down on power so i am in the middle of rebuilding an so far its cost me £46 (including a tool to remove the bearings).
the most expensive part of the rebuild will be the oil! but i would rather try an rebuild it my self than shell out £1000+ on a new unit!
i have a few pics of the inside of the charger if anyone is interested?

hi guzzler
yeah thats another option i will have to look into!
maybe rotrex or kit supplier will have a new option for customers?

[carlo]

Hi mate I will make the lad aware of this thread see if you can help him

yeah no problem.
i cant say i can 100% help to fix his problem but i think its better to have a go than just leave it go to waste.
im actually making a little "how to rebuild" from my experience and all being how well it actually goes i will post it for other users to have some idea of what to expect an a heads up on them.

no problem mate, here they are.




sorry about the writing its for the "how to guide"

[Spiky]

interesting to see whats in my supercharger

[paul-h]

Nice one mate! Is there wear on that shaft?

[frsjon]

so its not a geared system as such just runs on bearings...kind of the same as they use on seadoo's..and they dont last very long ...pretty much a turbo with a pulley instead of a exhaust housing..

[mikemcc03]

Hi guys.
Its a very simple setup to be honest
An yes there is slight wear to the shaft but a machine shop is confident it would polish out as there is no actually damage or roughness on the parts.
I'll keep you all updated as I go along.
It takes no special tools to dismantle the charger at all.
Once the "how to guide" is finished I'll post it up for others.

Good on you mate!

thanks mate.
ive been through the internet for any kind of guide an no luck whatsoever!
ive gathered some handy info which i'll also include.
i just think its ridiculous that you have to straight replace it for 1000+ quid
the only think i still think is ludicrous is the 100 quid a litre for oil!
i have a list of supposedly compatible options but need to research which will be the best for it.
if any one can help on this i'd be eternally greatfull!
thanks all

Is the eaton charger found on the likes of a mini cooper s any different to this one? Only I know someone selling one!

[Spiky]

Like chalk and cheese

Google will show you

[mikemcc03]

a completely different kettle of fish the rotrex is the size of an alternator maybe smaller
and has no internal gears
but the eaton is a screw type charger (could be wrong) an is a fair old size.

like spiky said chalk an cheese.
but would be alot easier to find info if it was :/

A friend of mine is building a high boost supercharged 306 rallye using the kit commonly sold on the gti6 forum. I will direct him to this thread.

Ah I see! Owel! Ha!
