After just reading this months miniworld magazine I am led to believing Supercharger is the answer to my problems.

In my mind I think a 1275 engine with some uprated cam, a metro turbo head, HIF44, Injection manifold and an Eaton M45 charger.

First question is level of difficulty to fit, how long would it take, my brother is well into his knowledge on mini's and a friend has supercharged his before now, so I have help.

Reliability, how reliable is this?

Alos whats the deal with the intake manifold and needle, I don't want to spend 1500 english tokens on the kit, when I could save £££'s in doing it myself. The friend has access to many machines with his job and made his own intake for his so that isn't a problem, it's the needle I am concerned with, as this will have to be profiled in some way?!

Lastly, the decompression plate, can this be made or anywhere it can be bought from?

Help please, very intrigued into doing this and opinions are welcomed!

Thankyou

if you're changing the head then just open up the chambers on the new one to drop the CR save having to use a decomp plate. no need to go for a turbo head either, the only difference is the sodium valves and they aren't really needed.

the needle will be profiled when you get it setup on the rolling road.

thanks for that! just wondered if a way to get around the needle, would be to use a weber, I don't know anything about weber's but just wondered if this would be better for air flow etc??

[Turbo Nick]

you'll still have the same issues with a weber but instead of a needle you'll need all the right jets.

[Turbo Phil]

Bud's right, you'll find the SU far easier to tune, than messing around with venturis etc in the weber. Besides the SU is a great piece of kit & underated by most.

So it's a hif44 all the way, is there a way I can profile the needle myself or does it have to be a certain shape?
Anyone know how reliable it is, more often than not it will be a daily driver to uni and to work, only ever pushed at weekends?!

As long as you keep boost to a sensible level and the whole thing is properly built it should be perfectly reliable. for gearbox and diff reliability keep power no greater than 110bhp.

Yes you can profile the needle yourself, a lanbda gauge and sensor make the job a whole lot easier.

[TheKing777]

Thanks all for the help, much appreciated! Just need to gather all the parts.

[Turbo Phil]

Yep ! I used an Air/Fuel gauge and a lambda to help when i profiled my needle. It's well worth the £150 it cost me. When i took my car to the rollers, Peter Baldwin said the fuelling was spot on. So the gauge must be accurate enough, & the power figure says enough !

[Turbo Nick]

did mine the same way aswell, best £200 i've spent i reckon on that wideband gauge. It's a bit long winded but well worth the effort, my RR bloke was amazed when i went for a power run.

Just had an insurance quote for a 1275 and for a 1275 supercharged and I am actually astonished!
I turned 18 in august, will have been driving for a year with no claims and no convictions in march, I'm male.
My renewal quote is:
£900 for a standard 1275, with tops of 75bhp (easily going to be less than this!)
£1125 for a supercharged 1275 with approx 110 bhp.

Yes will be be fitting a supercharger now!! Can't wait.
I officially love Adrian Flux insurance!

i think this is about the only time i'll say i'm glad i'm old, lol. i pay about £300 on mine with breakdown and all mods. would be cheaper if i didn't live in a ghetto, lol.

Very true but I must admit I was expecting in the 2000 range! Student loan will pay for the insurance. All my mods have been added to the policy as well so happy days!

[Wil_h]

£1100, I pay about 10% of that for a 998 turbo, and thats only limited to 8000 miles.

Maybe I should accept that I'm getting old.

[TheKing777]

I wouldn't say old....more experienced, I'd say! What sort of gauges will be useful in this conversion, rev counter is a must but what else would be useful?

Would an oil cooler and larger fan be necessary?

How difficult is the fit as in how much time should I allow for it?
