Not much, lol
If everything is in tip top shape you might be able to hit 110...downhill with a tail wind.

kinda like the v8 I see lol

You can get 120mph out of them ,I managed to pull that on autobahn with a 2.8 5 speed manual.Maybe its easier with manual but it can be done.

Re: Top Speed?

Most of the EFI cars without speed rated tires (V or Z) were limited at 115mph +/-. Most of the auto cars will get up to about 120-130mph before the 700R4 will downshift to 3rd and rev the **** out of the engine. Tons of exaggeration about top speeds on the forum.

Re: Top Speed?

My low 88 manual has hit 122mph.
110 was easy then a long pull up.
