110, but it had a lot more left in it (13B swap Dellorto DHLA 48, full RB exhaust) but I didn't want to get hurt or arrested so I slowed it down.

The rx7 i havent tried yet. I just got it. Besides the tires may explode. They are dry rotted.

But i have been

192 mph on my Bike (Started getting a little light)
176 mph in the Merc (Ran out of Road)
155 mph in the Jag (Passengers got Yancy)
144 in the Rover (Thats all it would do)
147 in the F350 (thats all it would do)

I will post the mazda's speed as soon as i get it safe enough to try it.

haven't maxed out the 7 but before that i had this engine in a '75 808 with a speedo that went to 130. i ran it up to bout 120 then let off. it was still pulling tho so i would've made the 130 mark with on problem.

210km/h or about 130mph. Got some serious front end shake so I let off fairly quick. Was in Indiana at 2am, so I decided to see what she would do. I attribute the shake to the stock steering box and poor high speed front end aerodynamics. This was before redoing the suspension/steering/engine. I want to try again with some aero improvements, but at a sanctioned event.

138 mph in a Ford CrownVic.

160mph in a friends ported 12A with a downdraft webber.
This speed was determined by math and frankly I have never really been confident in the accuracy of the formula so I am not absolutely sure.

13x

70 1/2 Camaro speedo went to 150, pinned it
86 Mustang 145
76 Honda CB750F Supersport 130+
Those were back in the NYC area

Vegas
79 Rx7 120+ yes I have the 130 speedo, and that will be topped

of course none of this was done on public road
