I hope to see you again some time soon.

Hi Jani,
nice to see some other finnish here :)
Hopefully I can see the car on thursday in Turku mini meeting...

I can't believe nobody has asked this yet, but what power is this beast making?

it looks like a genuinely amazing setup Jani, such an impressive feat fitting all that stuff into the mini engine bay, and actually getting it to work!

Truly amazing Jani.

Great write-up as well in this months magazine.

I can't believe your first maiden voyage was 1600 km to the IMM !! Nice talking to you on the Saturday at the show.

Hope your return journey was as good.

Richard.

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

Hi Prawn!

I must say, I also wondered that nopody ask it earlier!

Quite far from what I want it to be!!!

At the moment in 5200rmp area is 160hp and more than 220nm torgue. Al the way from 2500rmp I have more than 160nm in use.
After 5500rmp it goes away too lean and just after that 5500 it start to get more boost!!
The boost start rise just after 5500rmp 0.80bar--, 6000rmp 0.92bar and 6500rmp there is 1.05bar and the limit is 6900rmp.

I have there now standart SPI fuel line! So it is far too small.

We don't have time to touch ingnition yet so there is also more to do and that's how to get more power! Now we keep it in safe area just in case to get it run well!!

So there is a lot more to come!!

Unfortunately the autumn is quite far here in Finland already so we have to wait news untill spring. (may)

Remember there is still those 60hp nitrous to come.

Jani, i don't think you'll ned to 60 hp of nitrous, even a small amount will make a big difference with the supercharger,

a mere 25hp jet increase in our turbo car made a big difference,

Hi Richard.

Well no...

Close to stansted airport altenator rotating shaft from supercharger snap!!
So there was small panic in the air!!!

Thank good my brain some how work at the moment!

We look place where to find bateries and some cabel.
I put +wire directly to startmotor where is all major +cabels and extra batteri was other passenger side, also a -cable goes directly engine room.

We keep changing beteries from my car and my mates car and that how we drive more than 800km

So it was not homey trip back to home!!
But here we are!

Hi Carl.

Well I have to grant that a bit afraid to use those nitrous...

I have those smaller jets in home so I have to think what to do.
Maybe it is more sensable to use those smaller jets!

Wow, those are the kind of figures I was hoping you would say!

I'm going to be making a similar kind of setup to yours, although far less electronic, using a turbo carb and megajolt for the ignition. if i got anywhere near those power figures at any RPM I'd be very happy indeed!

Do you have any issues with DET running 9.13:1 CR? I'd imagine you've got a fairly conservative ignition map to keep things safe?

If I remember right.... when boost is close that 0,9 bar igniton is close to 26.

So answer is no worse..

I find a full 50hp nitrous hit in second gear is some what of an unusual feeling as the car suddenly starts to cover large amounts of distance in a relatively short amount of time What will 60 be like ontop of 160

Thing is, you get the bug and want more. I drove the missus 998 Seat Arosa the other day and couldnt believe how crap it was

Im still using a standard transmission on the mini, and they way I have been using it recently, I dont expect it to last out the year

Target for next year is run 100hp fed in from 30 over rpm rather than the normal over time, should be kinder on the standard box . The turbo will have to wait for now and I have been concidering keeping the NOS for a 25hp shot to spool it up

forgive me if this has already been asked Jani, but how have you overcome the issue of boost release on over run and idle?

it's the one aspect of my build that I'm uncertain of at the moment, I had planned to use an SSQV thinking that it would remain open on idle, but apparently this isn't the case!

Any details on how you did it would be great, as looking at the pics all I can see is the charger> intercooler> throttle body with no take off for pressure release at all!

cheers

HI Nick.

I think this image tells you much.

I see Jani, some kind of blow off device with a mini filter!

Could I be simple, and ask what exactly that is? and where I could get one?

I've been looking for info on what's used as standard on the bini's, but there seems to be little said about it, and nothing uprated available for them at all!

Mr. Prawn, the friendly Crustacean- slowly making steps towards forced induction.

OK, so a small bit more looking and am I right in thinking it's the standard valve from the bini cooper S? with a flange to fit it welded into your pipes?

Is it actuated just like a dump valve with a vacuum feed from the inlet manifold?

Mr. Prawn, the friendly Crustacean- slowly making steps towards forced induction.

Correctly!!! From bmw Cooper S

As Mini Magazine story tells all flanges are water cut by the locally company.

That's better Janni.

Presume no significant rise in back pressure ?

Well.... Some updated images from Cabriolet.
This year I have had a lot of different kind problems with this car.

Now there is a second Cooler down there and that hight one is now water cooled Cooler.
Same time I finally come wiser and decide to put that alternator better place.





Now the alternator is much better place.

Nice to meet you at Karlskoga Jani. Incredibly fast car, and obviously you're a good driver :)

The packaging is truly amazing.
