This mimics my own experiences. I buy NOS Regina chains whenever I see one.
Many years ago, Ausca tried using a single roller chain conversion on the race GTA engines. Sprockets were cut down for the chain. The chains were Regina, and this did work, but they did stretch quite a bit, and they were replaced after every race. Depending on cams used we could break them which was a mess, and the idea was eventually shelved.

More issues....

The Duetto sat in the trailer since the rebuild of the engine following the missed shift late last year. Busy with building the engine for the Coupe after selling the Montreal engine. That car is now a mid front engine 2 liter, race car.

I entered the coupe for the Mitty (rd. Atlanta again) But my plans to race it was stalled by a noise in the engine. I`m hoping it is just a rod bolt hitting the windage tray...

So I took the Duetto instead. I did a few laps thirsday noticing the wide band O2 meter was showing high 11s and low 12s just before the braking zone on the back straight.

So I pulled the main jets (200s) and replaced them with 190s. Friday qualifying the AFRs were back to high 12s and low to mid 13s. Perfect I thought.

In the Friday race I burned a hole in the #3 piston....

Ed (alfapartical) pointed out to me when I told him that at idle the O2 meter was showing 21, that that was a signal that the )2 sensor was not working (cooked from leaded fuel). I should have questioned that ads it always read in the 15s at idle. Shame on me, and as well there was 3 more O2 sensors in the trailer.

Racing was over. (I don`t work on the car at the track.)
So we pulled the plug, stuck a hand towel over it`s hole so it could make it down to the grid for the public viewing of the Alfas.

Pic below was taken by Steve Piantieri his Gulia Spider is the red one in the pic. He blew up a brand new crate race motor in his Mustang race car on Friday as well.

Wideband AFR meters are a mixed blessing in race cars. Great for setting up a new engine configuration but maybe best ignored after that unless you are always on the look out for the last couple of HP.

I took the photo from Patrick, the HSR photographer, who does such wonderful work. I will forward your appreciation to him.

We're taking "Ronzoni", my tri-color 1750 Spider to Barber Motorsports Park next week for the HSR event. It's a long haul for us *575 miles*. I welcome any Alfisti to the event. As usual, all my uploaded photos appear upside down. Let's hope it's just my photos, and not my car.

If the Administrator would please rotate my photo for me, I'd appreciate it.
