As per title.

Ie their maximum flow rate (or maximum RPM if thats how they work out safe limits of superchargers) etc etc etc.

Theres a company in Surrey called VmaxScart

They do a conversion on Mpi Mini's using this charger

Intreresting stuff, but dont help me know what they good for power wise.

IIRC they good for about 200bhp when they fit smaller pulley etc on CooperS's but dunno what boost that is and if they can go further.

Stuart Gurr is a very helpful man

Bloodyhell, if BBR are to be believed then 250bhp is possible from one, but still no word on how fast the charger is spinning for this.

BBR ?

Stavros

Brodie Britian Racing, the old Cossie legends from back in the day.

They do Minis now!

Inc a Turbo one that runs 30psi boost!

iirc max rpm 14000 and there the cheapest of the cheap for a super charger, like buying an XS power turbo

Stavros

Bet they not held together with glue like XS power turbos tho

If you fit a 15% pulley you'll see 14-15psi, standard psi is 8-9psi. If you fit 17-19% pulley you'll see I beleive18-19psi which really is on the limit of a standard supercharger. Most poeple that want anymore boost use an uprated version, this make a different sound too.

You can pick up a nearly new supercharger on ebay for aprox £100-£150

Stavros

cheers gra, and yes, ebay made me ask this question

so 19psi, and according to mark 14000rpm.

whats the % bit mean gra? 15% what? (im bit new to s/c so this might be an obvious thing, but i dunno)

% difference in size to the original pulley?

Stavros

i was wondering if it was that, or a pulley size that makes supercharger RPM 15% higher than the engine rpm, or, well, i dunno!

Grahamxx

No worries , 15% means its 15% smaller than the standard pulley, which means the supercharge rotates faster giving more boost

twin charging steve?

Stavros

Cheers Gra, just need to find out for deffo about the supercharger RPMs etc now.

Greg-

Not on the GTR mate, tho itd be cool, itd be more development work and complication i really dont need

Could be a possibility on the SX but not something im immediatley thinking about, but if i pull the engine out i might look at that option yeah, as low down power on CA18s are bit wank IMO, but then itd need aftermarket managment etc to get the fueling and ign right, and thatd make it cost money.

Mainly just looking at it from a learning and potential future ideas point of view, i like to learn, and always good to know about stuff you could do rather than do what most people do and jump into a project without realising its crap, or theres a better one they couldve done.

big_wig_074

lol!ive been thinking the same bloody thing!

Stavros

aahahahahaaa, checkitoooot

There ya go, all the info.

14000rpm limit it seems.
.75litres of airflow per revolution.

Its time for sums.

Im tempted to get one of them chargers off Ebay just so i got one, even without a use for it, cause who knows how long they will be for sale on the cheap for?
Are CooperS's still in production?

email this chap, his name is rob. he appears to be somewhat of an oracle on chargers, more so eatons. Very helpfull.

escortrsmatt

cooper s` are still in production, also as for power limits on their standard chargers, when we fit a john cooper works kit at work it includes an uprated supercharger.(older cooper s` 200bhp newer/facelift cooper s` 210bhp)but that is only on a 1.6litre engine.
