Cabriolet 1399cc superchargered and N2O **** UPDATE ****
Turbo Mini Forums

So I think now is a good time to introduce myself.

My Cabrio was featured on Mini Magazine October issue. There you can red more about the car.
Mini World little later....

In the summer of 2008 I got it in my head to do a completely different version of a superchargered Mini.

This resulted in using the following parts to acheve perfection.

Well pistons are from Avonbar and diss are self made by Ian Hargreaves 15cc Accralite, 73,50mm bore. The Piston compression ratio is 9.13:1

The head was fully modified with new race steel valves, inlet 35,7mm, exhaust 31mm with bronze valve guides. The valve seats have being changed so I can use unleaded fuel.

The camshaft is a Piper billet 285 scatter.
The rockers are full roller hi-lift 1.5 ratio.

Crank is from MED engineering with a 82,3mm stroke latest specs, Re-ground, Ni – Tempered, Crossdrilled, Wedged, Bladed & Backdrill. I used a 82,3mm stroke crank because I wanted 20cc more capacity compared to normally used 1380cc engine and that’s why it how has a capacity of 1399cc

Cooper S lightened con rods from MED engineering and a Finn turbo cooler.

I have also added a 60hp Nitrous system.

An Eaton M45 supercharger and at the moment I use only 0,8bar/11,6psi boost. (I have now too small fuel line so can't use 1bar boost)

I also added a cylinder head gasket from Cometic high pressure gasket, which is able to handle a high compression ratio and boost without any problems.

Ultra light flywheel and backplate from Mini Spares

I use a Haltec ecu and I have a Jenvey throttle body whit 2 injectors.

The radiator is made in Finland and it is a 3-core system and it is almost in its original position.

I have mounted a second radiator under the right wing for extra cooling and I found it from a Derbi motor cycle and it fits well into the wing

Is this it?

If something is worth doing, it's worth doing half of.

Read about it yesterday in the October issue of MinMag.

Interested in how well the ECU works.

Here you go

To do it in future you need to do the [img] tag before the url then use. {/img]

obviously use square brackets or it won't work.

I used the squiqqly ones to show you.

Wow, very nice indeed.

really nice car! i would love one of these cabs but there a bit pricey still.

i dont get the intercooler set up tho mate?

no longer a series, but still 1.3 turbo.

Nothing wrong with your english or engineering!

'Where does the engine go?'

Lovely job, interesting injection setup, be nice to know how evenly spreas you fuelling is across the shared ports.

Before upping the boost check out this thread http://www.turbominis.co.uk/forums/index.php?p=vt&tid=312408 I think you'll be at the useful limit of the M45 cwhere you are

Is your alternator chain driven from the charger??

i was looking at this at IMM for quite a while and it did look really good.
If I remember correctly it definitely looked like the alternator was driven of the charger by a chain.

luke

Yep chain...

Here is reason (copy from text what I send to mazines)

I started the project I wanted to run the alternator from the supercharger. (Which I believe has never being done before) The problem came about because the supercharger runs at a lot higher speeds than the alternator needs to operate correctly so I have to figure out the correct gear ratio so that the alternator would run at its correct speed. So after a lot of trial and error I figured out the correct ratio. So I started to get gears together with were all hand made. The next problem I had was that I needed to figure out the gear material as we figured out after about 5 miles that nylon melted so we needed to look at something else as the torque from the supercharger shaft was huge. We tried gears hand made from aluminium which was not strong enough for the job. Then we cane across special hardened light weigh steel which worked great. The next problem we had was to figure how to keep the gears in mesh. We first tried different belts which all ended in disaster and we in the end tried a special chain which worked really well. This has worked flawless up now.

Of course there is self made shaft inside the supercharger, original shaft is too short, so I have to break down that size of supercharger and plan that new shaft with extra outside bearing.
