I currently have a pretty mild 1293 Tarmac Rally car, The engine was built for consistancy and reliability. Webber, Mild cam, forged pistons roller rockers, but to run pump fuel. The engine has maybe 1,000-2,000 klms from last rebuild.... Its no rocket at the moment !. Im interested in what people have done with Supercharger options, not just options but results and who actually did the conversions in either Mellbourne or NSW.....

Thanks

Maybe talk with Graham Russell, he has a forced induction cam sorted & will have plenty of testing results for you to ponder over

You should put your heart & soul into everything you do.

I have just ordered a vmax scart supercharger kit from the UK, will let you know when it gets here and bolted on.

what about the supercharger kit LINK Automotive/ High Performance products supply?

I have an SC12 from a AE82 (I think) Corolla, and it goes pretty well. It's one of the famed "Ben's Kits", his ausmini name is 92 send him a PM.

From looking around it's fairly easy to say, bang for buck, Ben's kit is the way to go. However, no harm in being different though!

Last time my car was on a rolling road it made 82hp atws, and was blowing laods of smoke etc. Turned that that one of my exhasut valve guides has loosened and moved upwards! It runs a lot nicer now that that's fixed and probably makes a tiny bit more power and feels smoother at the higher rpms too.

My motor is a 1330cc Cooper S motor with standard pistons (as in low comp) Cooper S cam, S head, single HIF44 carb, cheapo LCB extractors all running through a (relatively) stock mini K gearbox.

For comparison it made about 50hp atws before the upgrade so it did give it a decent punch, and not bad for only 5-6psi of boost (can make 7 if you ring the crap out of it but that's just not nice )

not an eaton supercharger.. vmax scart is

i've seen some pics of the manifold for the Eaton. and i wonder how this makes any power at all

A bent pipe with a triangle cut in the side of it...I guess it is forcing the air in so easy of flow doesn't have to be perfect

i would love a triangle

the first pics should be one of the buyable kits

further down there is a homemade one, following the triangle idea


luckily, a friend of mine now goes a differend way. after getting rid of the carb system he used injection and now added an intercooler after relocating the charger

I have yet to read anything bad about the vmax kit, im sure it works quite well. I dont understand any of the engineering how or why it works stuff, manifolds smanifolds! I have a thing called blind faith

i got a jonspeed kit to put on when i finish off some other things. ill hopefully take some pictures of the job. Can get over 75% hp gain from this kit supposedly. so ill let you know how it feels before i blow my box and diff

don't get me wrong, the kits do work. we got 100HP out of a 60HP engine without much work.
but this setup is only scratching at the surface of the possibilities of this charger. and i don't like wasting energy, due to unnecessary hot air

i have only heard of LINK in melbourne, they supply and fit complete kits.

P1xV1xT1xk=P2xV2xT2xk k is constant for air
There is some interesting test results on super-charging on the net. Try RB racing and the sites for some of the super-charger manufacturer's.
There is also a site that deals with blown drag bike engs. the same basic principles apply.
One of the ideas is to have the blower mounted in a good cold air flow position and they are using a expansion chamber instead of inter-coolers[less air flow restriction] to drop the air temp before it enters the eng.[compression =heat, expansion = loss of heat]
One other thing they are doing is looking at the cam overlap[easy with T/C heads] so the cylinders have a increased scavaging of cold air. The volume per cycle is increased to over come the duration of v/v overlap.
Some of these engs are running a max boost of 3bar[45psi] with sequential opening intake butterflys on the blower intake to have better low rpm/load control. All are blow thru carby or injection systems.
Nothing new with this idea, look at a rolls royce merlin eng, they had a scroll type blower with internal boost regulator.
One problem with the SC teflon coated blowers is they do not like high rpm and pressure. the teflon peels off into the engine. There is a site where a bloke stripped the blower rotors and fitted a wear seal to the rotors.

I assume it is the same supercharger as fitted to my 03 JCW. (standard SC wasnt teflon coated back then but the JCW conversion came with upgraded teflon coated SC) I have run 17-18psi for the last 3+ years with no problems, the car is constantly bounced off the increased rev limiter of 7200rpm. I have never heard of any problmes with the teflon coatings within the MINI communty.
