Supercharger question
Turbo Mini Forums

I have noticed a load of cooper s chargers coming up for sale, are they easy enough to fit to an A series (with a bit of fabrication) I am running an mg metro 1275 would the compression ratio be ok?
Cheers

Vmax already do the conversion kits.

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

nope CR way too high on an mg engine

waiting for the big long post by hedgemonkey...........................

Metro turbo weekend driver,Mini turbo in the making again!

sorry but I think Vmax are having a laugh with the price of that kit ?2k+!!!!! you can pick the chargers up for less than ?100 and even with the manifold fabrications and pully setup that is ott IMHO.
So what head would I need to look at on a 1275 lump?
Cheers

its not the head, its the pistons you need to worry about. most heads have the same chamber size until modded

I have to agree, I feel that 2k for the supercharger kit it is waaay high, as you say its possible to pick up a 'charger for peanuts on ebay, and the kit just uses a 1.75" su.

Its a shame that mr vmax doesn't (as far as i'm aware) sell just the manifold and intake/ carb manifold seperatly. I expect that is only a mater of time before somebody else does offer just the manifolds.

if you wanna get some made, give maniflow a bell, they've custom made for me in the past and their work is outstanding!

I was thinking of getting a supercharger to replace my turbo, but then I thought about all the effort that i went to to make everything fit and work properly and i thought bugger it!

Just stick with a turbo, the compressors are more efficient anyhow! Also you can adjust the boost easily, where as a supercharger you have a fixed boost only (depending on the size of the pulley)

Please nobody think that I'm diss'n the vmax kit in any way, just me rabbit'n on...and on....and on...!

Hannibal: There are two ways we can do this: the easy way and the hard way. In a few minutes my friends and I are going to come down on you like your worst nightmare. You're gonna wish the Earth had opened up and swallowed you whole.
bad guy: What's the easy way?
Hannibal: That WAS the easy way.

The kit is actually ?1650, fitted is ?2k.

Personally i dont think this is bad value at all really. There are a lot of bits to put into the kit and i pretty sure it has a modded head etc.

Its a pretty good deal plus its been well proven

Im still sticking with a turbo though, more smiles per mile

Use the SEARCH function and there has been no end of topics on superchargers.

still think it steep though. I got my t3 rebuilt at the turbotechnics with 360 thrust beraing for 500 notes, and my head for 550 from SRE, carb and manifolds were 40 quid and intercooler set up was 70 quid, fuel pump and reg were 40 quid, zorst down pipe 40, bulkhead box was 50 as was the oil feed. that totals 1340 by my maths!

Anyhow, horses for courses and all that! Sure its a fab bit of kit.

bear in mind he cant just lob any 2nd hand stuff on, carbs etc have to be rebuilt, add an air filter adds a few quid. plus he modds the supercharger to fit etc. RR session thats included... the list goes on
guess all the bits add up, plus its a business at the end of the day not a hobby

Not much different to your parts list really

Yeah each to their own. from what ive heard all the people how have had the conversion have been very happy.

What about the fact he developed this kit?

Should he not sell a kit at a price to recover his costs?

Thats the problem with mini people, they want everything as little of possible regardless of how shat the qualitiy is !!!!!!

Well said Alex !
If it was so easy, anyone could do the conversion ?
Look at the problems Stu's having ! , or better still, look at the prices of other s/c kits on the market... ?2000+ and you dont get a head.

Chris

I think the kit looks very good value, as already said Stuart had to develop the kit himself. So think of all the time he spend researching and developing before he could even put it on the market.

Look at the price of the Minispares and Minispeed kits, then tell us which is best value !

TRUE, BUSINESS IS BUSINESS AT The {takes cap loc off} end of the day!

Still a very neat conversion, and whether its supercharged or turbocharged, forced inductions the way to goooooooo!!

OK having read the comments above I would like to retract my comment reguarding the price as I did not realise the kit came with a modded head.
It is way out of my league and I would just ask the question, why would someone spend that much when I would imagine a turbo conversion is a very much easier and cheaper way to get the same results?

Edited by Big Mark on 20th Mar, 2005.

you'll probably find that you can easily spend a whole lot more than a vmax supercharger conversion when turbocharging

even gearboxes can easily cost over ?1500 you add in s/c gears & drops, LSD and CWP's etc

although i guess finding a good mg metro turbo setup and bang that in you could do it fairly cheaply, which is enough for most for a while......

Good points there.

The Bini supercharger conversion is a bastard to do yourself. Do not underestimate how difficult it is to fit. Stuart's conversion looks like the dogs bollocks to me.

The Opcon/Autorotor MS charger is much more thermally efficient and a blow through kit would be nice. The killer is the price of all the other bits. I'm using all new components and my final "good" engine build is awfully expensive (unfinished). Start thinking about some big money.

You could go Abingdon research and put the blower in the passenger footwell.

When you see a BINI blower, they don't look that big, until you put them next to your A Series.

Bugger off, I'm getting there.

what can i say , just came across this thread and most of the questions have been answered, because i offer a wide fitting range ,from race kits see Ian Johnson 's twini mini , lhd ,injection, minisprint, or road use with carb- with or without servo- , all use diferent manifold and pulley setups , each one is made by me test fitted to an engine if sold in kit form ensure fit , to suit customers engine /car configuration. It takes me 6 days to make the full kit up inc head , time is money , I stand by what i make and believe its good value for money/ power gained / ease of fit /reliabillity
I'm no stranger to the turbo conversion and relistically its not a relatively easy DIY fitment in 6 or so hours , although ultimately will probably give more power
will this years avon park meet see the might of the turbo finally challanged?
remember its not a mini unless theres and 'a' series under the bonnet !(or boot as well if its I. Johnsons)

it`ll be interesting if any superchargers enter class D,
carl and ian or out on there own !!!

Everyone knows that instructions only have to be read if the thing doesn't work....

Stuart, do you know what the quickest 1/4 mile time someones mini has done which has had your supercharger kit on? (and with only one engine)

Team Racing

Hang fire a min Jim and Mark - I'm sure Stu will agree with me when he admit's the M45 SC will never be a match for a well sorted and matched
turbo like the R5GT spec T2...
(or maybe a hyrid T3?)

I'd be intersted to see/hear one run though!

There was a geezer in class D with one of Stu's kits, that big ape looking bloke from London and Surrey.

Can't remember his times but the car was in full road trim and the bloke must weight 18 stone!!.

touch wood (not cloth), fingers crossed my new improved demo min should be at avon park - its not out and out race but - 93 mini cooper all standard car except for budget 165's , 1293 cc 36x31 head ,286 cam ,m45 supercharger , charge cooled ,emerald injection /ignition ,helical 4 speed box and wait for it ...2.7 cwp - at least i'll be cruising at 90-100 on the way there ,whether its on the way back as well is another matter!
like dave said its not going to be the sharpest tool there but i need to build an all round demo car , it did 15.6 last year when rough round the edges so if its in the 14's with all round drivabillity i'll be well happy !

faster than a light weight mini turbo running 5 or 6psi!

IIRC the Bini blower at 0.5 bar gets a maximum efficiency of 64%. Twin Screw blowers are looking about 84% and Turbos in the 80's. I suppose you could use a 2 stage series setup with a bonnet bulge! to get the bigger boosts.

Bugger off, I'm getting there.
