[Roadsters] 2-litre Roadster vs Porsche 911 of the day?

[Gary McCormick]

Thanks, guys. Interesting history stuff.

One thing that I got out of the Jay Leno video was the relative 
simplicity of boosting the early 911’s air-cooled boxer engine. His 
builder swapped in larger-bore cylinders and pistons and a longer-stroke 
crank to increase the displacement to 2.5L, and added high-performance 
heads (dual-plug, larger valves).

Cheers,

Against 911s, lotus elans, XKEs and TR5/6. While at the national level, in the east at least, Bob Sharp's major competitor was Bob Tullius in his Group 44 TRs, but at the lower levels I did quite well against all of them. Had a better top speed than most and could out drag them all, so at a fast track like Bridgehampton I always did well, but with the 'cart' suspension and power oversteer with a Detroit Locker at high speeds that can wear you down,  had to work harder at places like Lime Rock.

Don't think I ever went up against a really fully prepared 911. But then again they were never a problem for the Datsuns and Triumphs at the national level. Also the 911s back then were not the monsters they are today.
