I know he knows it's a 5 speed. When I emailed him, mentioning how much higher RPM he was claiming than most report, he responded thus:
"Doug,
I rarely take the Cobra out on the highway, so my estimation was a guess."
I'm feeling much better about this all the time, with numbers like those reported by Joyridin' I'm sure my contact must be mistaken. According to my calculations, our final drive ratios would be in the same general range (his 4.56 X .56 OD = 2.55 final ratio, my 3.70 X .68 OD = 2.51 final ratio), so I'm expecting numbers pretty close to those reported in Joyridin's post above.
Thanks, guys!
