For those that are interested this is what my snapped driveshaft looked like when I removed it - Shear Failure in Torsion:

'They' say imitation is the sincerest form of flattery.......

Well I should be flattered then as this morning I received a pm from a guy called Emin who is a mini collector and restorer in the US. He did the below for a buddy of his, turns out he liked my paintwork.............

My ceramic coating was around the £250 mark from these guys: http://www.camcoat.u...om/Exhausts.htm  I havent seen a Zircotec covered exhaust be put through the same as my coating to know if you still get a glow when under load, I know Zircotec is more expensive?!?!? Watch my dyno video to see what I mean by glow  http://www.theminifo...spec/?p=2479498

As for bleeding brakes you just have to be methodical and ask someone to help you. I started with the inner bleed valves on each four pot, then to the outer and then checked the inner again just for piece of mind. If you've never bled a brake system before I suggest you google it.

The first dry day in weeks was not going to go without blowing the cobwebs out

I happened across a buddy of mine in his M5, this was his response:

I attended the Supercar Sunday Breakfast Club at Goodwood on the weekend, amazing turn out of cars and about 15,000 people. I blagged it past the car parkign guys to get myself to the gate to be confronted by a man insisting that I had to have registered online before the event to be able to get the car on the circuit to display it. Fortunately one of the people in charge at the gate, a few meters in front of where I had been stopped recognised the car as I could see him mouth "I've seen that car before, it goes like F**K", consequently I was given a circuit pass.....

Note crowd round mini, not so much round the 458 next to it........

I was at Goodwood on Monday (19th May) hooning around, this is my best lap of the day - 1:37:8.

Here's another clip from Goodwood the other week, it shows how it reels in the other cars....

Stefan, If you're referring to the K20 site then yes I have and I also follow that lot closely. If you know that site and others you may know the name Jose Mercado, or Merc Racing?? I do a lot of 3D work for him, almost all of what you have seen from him in the last year or more has been through me. We have been working on an supercharged air to air intake manifold for the K20, for use with various superchargers. Unfortunately it wont fit in the mini so I wont get to use the fruits of my labour. I have designed multiple throttle body to supercharger inlets for him and a belt tensioner/extra idler pulley for greater belt wrap on the charger pulley. Here's a link to the site (http://mercracing.ne...ercharger-kits/) and a few renders of the work I did:

As for my quest for more power I don't have any firm plans or the cash to do so. Ultimately the plan is to swap out the M62 for a 2.3L Whipple Twin Screw, water to air intercooled, dual 60mm throttle body (like on the big block US stuff), remove engine coolant water pump and replace with electric pump to allow me to mount the SC low on the front of the motor, reducing the c of g. All in I reckon about £4k to upgrade, I might get some back if I sell my JRSC and I have a good source for parts from the US.

The only problem is if I do the above I'll never get started on my sprint mini so I am torn, I would love to build my own from scratch and have started on some modelling work but arent far enough to warrant starting anything yet, plus I am struggling for room in my current place.....

Those with a keen eye will be able to tell this space frame design is not to scale for a mini, it was a first pass at a spaceframe and I was using very rough dimensions. I have improved the design considerably since this attempt but gonna keep it under wraps for now. I have a rough Hayabusa engine model and My wheels, tyres and brakes are also modelled but there is so much more to do and not enough hours in the week.

Planned Upgrade of Exhaust System:

I am getting fed up with constantly being hassled at track days for being too noisy so I have hatched a plan. I am going to swap out the original 6" x 18" absorption silencer and the extra 5"x18" absorption silencer that I add for track days and replace them with 2x 2.5" inlet 6"x14" round Flowmaster DBX silencers from the US, two of these in series should remove a ton of noise and not be much more restrictive that the two straight throughs.

If you're interested in the information on the silencers here's a link: http://www.carid.com...technology.html

I have been static tested and drive by tested at Goodwood so I know where I am starting from, so will be able to report how well/or not they have been in reducing the noise.
