Finally got the clutch working and the boys and I took the Mini for a quick spin around the cul de sac. Still needs tuning, but at least it is moving!!!

It is running, but… the clutch doesn’t disengage
August 1st, 2013

Well everything is moving along nicely. Finally got the car running and it sounds great. It took a couple of hours to go through the break in process, changed the oil to take the car for a drive, and… the clutch won’t disengage. Feels like this car isn’t going to make it on the road before the snow comes. I’ve already had one volunteer indicate they would push me around the block if it comes to it.
One of the experiments in this car was to try an RTS clutch. This appears to be an excellent alternative to switching everything out to a pre verto clutch and was fairly easy. In the picture below you can see the double up’d fingers on the revised pressure plate.
Now the hope is that making this change isn’t want is causing me the trouble. Unfortunately it is looking more and more like I am going to have to try and get the clutch cover off and see how exactly this thing was put together…
As an aside here is a link to instructions on the RTS clutch. http://www.turbominis.co.uk/forums/index.php?p=vt&tid=437563

Engine and gearbox are built
September 5th, 2012

Last night was a big night as we bolted the engine and gearbox together. I realize that I have been very delinquent in my updates and there will be some catch up that is done on the whole build process, but I may still get to drive the mini before the snow flys….
Here is a shot of the gearbox. It took a bit of work, but I finally got it back together with the new baulk ring. Not sure what I am going to do with the old one as it is the source of all this craziness.
Here is another shot with the new LSD insalled! Not sure how long the old one was going to make it.
A shot of the engine waiting for the gearbox.
and one of everything bolted together.
Well…

Not much progress in April… still waiting on the cam shaft and only cleaned a couple of parts. Plus side is that this is my last trip to Madagascar and in theory I should have more time. Not sure if my wife agrees, but we will see.

Flow Results of the Port and Polish
January 29th, 2011
{ No Comments }
Well there has been a marked improvement to the flow numbers. There has been an 19% increase in CFM on the Intake and 21% on the Exhaust. The following is a graph of the flow results.
The Exhaust to Intake ratio hovers around 60%, which is short of the 70% goal, but seems to be pretty standard for these heads. Regardless their is a significant improvement. I have added some pictures to the gallery of Jesse’s work.
Crank, Head, Block, & Suspension Cleanup

Things are still moving really slow. The target of Mini Meet West is in question… 🙂 Hopefully January and February will be months that show significant results. I know I keep saying that…
Well the crank has been lightened and is off to be balanced; the head has been ported and the new valves are being fitted; the blocked has been bored and honed; and I am slowly cleaning up a little more of the Suspension. Actually here is a before and after shot of cleaning up the break calipers.

Main Strap and …

Well there continues to be some build progress. I don’t have a lot of pictures, but here is a quick shot of the new main strap. It needs longer studs, but those will come shortly.
There are few outstanding parts that need to be ordered, but hopefully everything will be together for Christmas! I am hoping to also get int he garage and get some more done on the suspension, but there is also a Caribbean cruise to fit in. 🙂

Well even though I haven’t had much of a chance to work on the car Jesse has made some progress with the connecting rods. Have a look…
Step 1 Connecting Rods
Step 2 Debeaming Connecting Rods
Step 3 Polishing the Connecting Rods
I sure hope it will be running by the end of winter… 🙂 Hopefully when I am back next time I will get most of the suspension sorted out.
