Default top speed with 4.785 FD???

whats the top speed using the 4.785 FD in a GSR tranny? how about a b16 trans?
i've heard of people doing 70 mph and being at 5k(i think that was a b16 trans--if that makes a diff). tia

i dunno but holt chit. that seems even too much for draggin, You'd probably need a 10k redline to actually make it to a decent speed before you hit the rev limiter

What's your tire size, inlcuding rim diameter?

Assuming an 8300 RPM redline, your top speed would be 149 mph with the 4.785 final. It'd be 162 mph with the stock 4.4 final.
