Thanks, Craig, I do Love the more rare 2 year only T5. What sunroof is that? I too, have a 41,000 mi. T5 Coupe stored away, on my bucket list, from '69, when I broke an early 50mm crank, in my old "bitsa" autocross engine, with way too much Racer Brown 296* light Speedster race cam, in the heavier 1582cc street coupe.


...now what was that my WWII P-40 pilot Dad used to say,..."the only problem with experience, is the price you pay to earn it..."


(I've been hanging out over on the 912 Registry BBS, trying to help the folks over there. I've been referring anyone with a real interest in these 616 engines, to buy your E-book, still one of the best, from which I learned a lot! My paper copy has your autograph in the front, and I still have my "DOPE" button, which came with it. I'm still studying, trying to deserve it... Jack & I talk about you on occasion. Be safe, and enjoy the cool coupe.)

Dyno tests show the torque is better at rpms less than 2000 with the stock 022 and BR18 curve. When one of my customers changes from an 050 to a BR18 they always say how much better it is at the lower rpms. The torque is slightly better with the 031 that starts about 1100 to 1200 and shoots straight up to roughly 1800 rpm. (They are all different.) I set my 022's and BR18's to start a little above 1000 rpm so that people with Solexes and worn out carbs can get their idle mixtures set correctly. No complaints so far. Engines with higher performance, twin plugs, hot cams, etc. can use a straight line "curve." My thought is they don't need that extra few lbs of torque because they have plenty to start with.

Bruce Smith's excellent site has all of the Bosch curves. I'm sure if someone sent him a 0012 he would be happy to post it's curve too. I'm guessing he must be holiday or would of commented already on this thread :)

Amen, John, one of the "Masters",


My findings, as well, and Thanks, to John, who got me along the way, in my ignition study, several years ago, Kudos, my Friend!
