AlpinA 2.o L RacinG EnginE

Back in the states as of Monday and about 14 hours of catch-up sleep (after 3.5 hours from Sydney to Auckland and the 12+ hours from Auckland to San Francisco).  What a great trip!  While I was gone my engine builder had left a message to come over and have a look at some of the work that was done on the mag bits.  Top images are of the partially assembled bottom end, bearings in - crank, rods and pistons. The other images are of the black chromate finished mag pieces - valve cover, upper timing cover and oil pan.  Gary Arentz did the work on these (slide throttle casing was also done by him), he really does incredibly nice work at a reasonable price - very well known in racing circles for finishing/re-finishing of magnesium parts including Hewland gear box cases and the like.  The finish really has a unique color that doesn't quite translate in the images and is something that can't be replicated with paint.

BmW ScreenSaveR

Still on Holiday for a few more days (Bondi Beach, Australia).  I was working on some screen saver's for my computer at home, this is one of the iterations, not quite right.....yet.  Going to go sit on the beach for a bit, 80 degree's or so today and bright sunshine.  Really a beautiful spot here.

QueenstowN, NeW ZealanD

I have been on Holiday down in New Zealand since 9 November, this is the incredible view from our condo in Queenstown.  We started off in Auckland for three days and then flew down to Christchurch to collect my son who had been studying at the University of Canterbury for the past sixth months.  From there, we took a two day drive down to Queenstown - what an incredibly beautiful country with equally nice people.  Very enjoyable.  Wednesday over to Sydney Australia and then back home to the U.S. next Sunday.  Lots to post of BmW related info upon my return.

AlpinA 2oo2 Gr.2 - GaS PedaL

Special cast aluminum AlpinA accelerator pedal for BmW race cars utilized in the my Gr. 2 AlpinA car (see top image) as well as various CsL race cars.  At some point someone poked and extra set of holes in the pedal to apparently change the height of the cable ball for the accelerator linkage.  Another small hole for who-knows-what was also drilled.  Just another one of the small nit-picky details I wanted taken care of so I left this with my friend Roger Hamlin (Hamlin Fabrication, Sonoma, CA) a few weeks back.  His suggestion for the "cheap" fix was to put a couple of stainless flat head screws in the holes and call it good, my suggestion was to weld the holes up and then grind them back and make them go away.  End product, welded up holes.  All that is left is to give it a light polish and then re-paint the three recessed areas with some red hobby paint.  Again, a minor detail....but then the devil is always in the details.

AlpinA - FaltZ "WerkS" 3.5 CsL

I was up at my friends (Roger Hamlin, Hamlin Fabrication, Sonoma, CA) a few weeks ago to rettieve some parts he had been working on for me (machining the Schnitzer valve cover to accept the AlpinA script/plaque).  Time permitting it is always better to go up there personally rather than have roger send the parts back via UPS or US Mail.  Why?  Because he always has really cool cars in his shop.  Currently two (2) BmW's - one a clone CsL race car the other this one, a "werks" Motorsport M49 powered 3.5 CsL.  I didn't check the serial number of the car, however I am pretty sure it is the AlpinA - Faltz 3.5 CSL from '76 that competed in various WTCC events including 6 hours at Silverstone and Vallelunga (amongst others), driven by Harald Grohs, Sam Posey and a number of others.  Check the "Driver's" thread for the Harald Grohs write up and and you can see him airborne (significantly) in a 3.5 CSL, same car......odds are.

AlpinA 2oo2 Gr.2 - FlywheeL

This past week I received a phone call from my engine builder, he needed some odds/ends (parts) one of which is the 20 mm (1,5) crank nut and wavy washer, both of which I learned are NLA from BmW.  I was able to source those from a local salvage yard.  The other item of business was the flywheel.  I had handed it over to him years ago and while it has been in a box in his shop since then, prior to that it was on the car....and for a period of time that car was outside under cover (on the East Coast of the United States).  Obviously, I wasn't going to have him install the flywheel in its "un-restored" condition (top image) so I paid a visit to his shop and retrieved it.  I wasn't really sure how to approach this one - take it to someone and have them media/soda blast it, or try to do it myself.  I opted for "do it myself".  I had some "metal cleaner" I purchased years ago - it looked like simple green, the bottle was so old the name of the product wasn't legible any longer.  Whatever it was - it worked.  I soaked the part in the cleaner for about two hours.  Whatever it was it did the job.  After the metal cleaner process, I hit it with a wire wheel/power drill and then final finish with a scotch bright pad.  Given what it looked like initially, it came out pretty good.  One or two places to touch up and then I am calling it good.  On the top few images you will notice a couple of  rectangular blocks of steel attached to the inside face of the flywheel, those are the pick-up's for the electronic ignition.  Bottom two images are of the Homologation papers (#5258) for BmW Gr. 2 cars that show the flywheel along with a number of other parts (twin plate clutch and 148mm connecting rod, etc.,).  Later this week I will try try to get the part weighed to see how it compares to a stock flywheel and or aluminum version.

AlpinA 2oo2 Gr. 2 EnginE UpdatE (10/15/2014)

I stopped by my Engine Builder's yesterday.  They had called me a few days earlier and left me a list of things they needed.  Somehow the 20mm (1,5) crank nut and associated "wavy washer" didn't make it with the pack of parts that came out from Louisiana back in 2oo2.  Who knows, maybe it did and it is in some random bag.  It still amazes me how many parts and pieces are associated with a car - even a race car that in theory has less of everything.  Those particular parts are NLA from BmW now so you either source them from the old nut and bolt shop or get them 2nd hand.  I opted for 2nd hand, a tensky to the guy at Double O2 Salvage in Hayward and I had my part(s).   Top image I like and not bad for an I-Phone camera - looking down on the polished crankshaft through the cylinder.  The others are of the pistons which have all beef fit into the cylinders and now just need final finishing (these are CP pistons) and the new 148mm Carrillo connecting rods.  This motor is going back together fast now and will probably be done in a month or so.
