Driving the 1934 Alfa Romeo That Beat the Nazis

"But Jano was Turinese, an outsider. The Alfa men initially regarded him with suspicion. In 1982, Alfa test driver Giovanni Guidotti told journalist Doug Nye about running one of the man's first designs on the dyno:

"We would take maximum power readings by just opening the throttle wide for 30 seconds . . . then alt! Because if not . . . she would break. When Jano came in . . . he said, 'No, no, no,' and he took the throttle and opened it wide and hung a weight on it.

"It was around 5 o'clock in the afternoon, and he said, 'Now I'm going home for a bite to eat. Don't touch the throttle, and call me at home about 8 o'clock to tell me how it's going.' We were flabbergasted. At that time, no engine would last very long at full power. But we quickly learned Jano's engines just weren't like Merosi's or English engines or the French . . . they were perfect, marvelous pieces of design and construction."

Everytime I see Will in here I hope to see Sprint updates... technically this counts so Im happy :)

Wow, I didn't realize there were castings done like that. Very cool.

The engine I have appears to have been built using most of the Shankle catalog from back in the day. Its got 8L cams, a ported head, and I'm not sure what else internally It was balanced and blueprinted, but I can't read the paperwork on it (the ink has faded.) Its an older build, but the guy I got it from says it ran great. (He's trustworthy, so I'm going to take him on his word.) Apparently it made no power below 4k and would pull 8K easy. (A bit like a 1300 Veloce engine). Apparently it dyno'd at 160 hp. Should be pretty fun.

Jaremco's son stuffed his 240 into the wall at Monterey this year. He had been having brake issues all week, and going into 10, no more brakes.

A real Autodelta sliding block. I don't even want to know what that set you back. Nice setup.

Back to Alfas, I've been pondering what to do about a clutch and flywheel. Since I'm running a hot 1750 in the Sprint, and a 105 series 5 spd, I still have to run a mechanical clutch. I have a choice to run either a smaller 101 series flywheel and clutch or the larger 1750 one. I kinda want to run an aluminum 1300 flywheel and clutch since it will be lighter and more willing to rev quickly. (and possibly act more like a 1300 requiring a few more revs to get it off the line. ) I've got an old Spruel aluminum flywheel, but the ring gear is chipped and they don't make ring gears for the flywheel anymore. I'll also need a starter, and before I get the starter (thinking gear reduction type) I'll need to decide on the flywheel. Any suggestions?

No, not an original. I got lucky and bought a good casting of an original. Then I took it to a foundry in Seattle to get it heat-treated. Had to face it, drill it for bolt holes, etc. Lots of nerve-wracking work, many hours spent. Never had to use the trunnion bar since I mounted the trailing arm directly to the rear bulkhead.







As for your clutch issue, I'd run a 1750 setup, because that's all I know. Multiple options from stock to full race, and guaranteed to handle the torque. Stock Bosch starters for it are already gear-reduction.

Jaremko hasn't raced in a while. The matte green flared Roadster belongs to Leavitt. But like I said, he seems preoccupied with other cars.

Hey, isn't this an Alfa thread? Let's get back "on track," heh heh.

Some details of the modified sliding block I installed in my race car a few years ago. I fabricated the bracket to mount the sliding block's peg on the diff housing. I also made a titanium trailing arm for the diff that mounts directly to a reinforced rear bulkhead.

Who's is it? I'm only aware of two roadster race cars in the PNW, the Purple Lips Racing lightweight, and Paul Jeremco's black 68 2L out of Spokane or Yakima (I can't remember, I think its Spokane.) There are a couple 1600s up there, but I'm not sure they get out much.

Thanks, Simon. I'm running a 1750 cc engine.

There is, in fact, just one very modified 2L Roadster that's pretty quick. Big flares, lightweight with lots of fiberglass panels. But the owner hasn't brought it out in a while since he got hold of an old Sunny with significant SCCA history.

Thats an awesome pic Nader!... DP, so you have something between a 1600-2000cc motor? Any Datsun Roadsters in your group?
