Bare minimum requirements for a Web 86C?

For a good street engine with no strip time.

I ran a Web 86C with CB 044 Ultra Mag Plus oval-port 42 x 37 (looked similar to your photo), Weber 48 IDA's, 42 vents and 10.5:1 CR and 1 5/8" header.  It was an excellent hot street Beetle, but required 91 octane (94 when at sea level).

(Later, I elected to have 44 mm intakes installed and moved up to 1.75" exhaust, but that was done in order to race at our Friday night Street Legal drags).

I ran virtually that exact same spec, only with a 1 3/4" exhaust and it was a really nice drive. Heads were 42x37 044's (hand ported), and I had 10.6:1 - previously had an 86B at IIRC 9.5:1 and it felt so much better with the 86C and the extra compression. Very drivable, I used it daily for a 45 mile commute when my every day car broke.

Thx guys!  86C it is!

What would you say was wrong with the 86B? I consider using a 86B in a street driven 2165ccm engine.

Thanks!

To be honest nothing at all BB, the car was great with it in there, but the block was apart for a bearing change and I had the parts so thought I would try the change. Definitely quicker (as you would expect) with the more aggressive cam and CR, and not just by a little bit, it seemed a whole different engine.

Thanks guys!!! Great info!  I'm really looking forward to trying this cam out!
