1st gen with a 87 turboII motor, large street port with small bridge on the secondary. T66. 11.44et at 127.44mph with 1.96 60 foot time. 2720lb. street driven. 20psi boost. Jan 04 changed to TurboII.
Didn't notice the mods you have on it. Wild guess, I'd go with 155. Why are you wanting to know....?

For comparison, top speed in a stock FD is around 160+. At this speed you are power limited and nowhere near redline in 5th. I would imagine that the top speed of a stock TII would probably be around 140 for the same reasons.

Top Speed 350 knots

I once had a TII that went 350 knots, of course it was in the cargo bay of a C-130 at the time. An ANG buddy of mine transported it cross country for me to get an engine rebuild. He had to log the flying hours anyway and transporting something was good training for the loadmaster. Does this count?

Ya I would say right around 160. The FD is not really any greater than a slightly modded FC. I would say RB turbo back exhaust would get you pretty close to a FD in HP alone.

The car felt really good at 8000rpms in 5th gear. The car I passed thinks he was going 250km. It just did not feel like 160mph. and the clutch was not slipping. If anyone wants to see the down sized 9mb video PM me.
Mods, "large street port", T66, four 1000cc injectors, spraying water. Blew a manifold to turbo gasket so boost was down to 1.3bar.

sorry for interrupting this thread but driftmeister how in the world do you have a 530i V8? did you put in a 540s or even an old 535s V8? and would that be a 1991 525td? not 524?

oh now back to the thread, i've hit 215 km/h on my TII but it was on the highway so you wouldn't want to go any faster or even that fast unless you're on a circuit or closed road.

the fastest I've ever gone in my N/A turbo was 147mph in 4th at around 5500rpm on the Nj Turnpike. The only reason I slowed down is because it felt like I was gonna warp through the matrix or somethin.

I have a s5 with full exhaust and got it up to 155mph. I have to slow down due to traffic but it was still climbing.

well from the book it states
turbo=176mph
N/A= 191mph
that does not mean the car can do it that just means that the gears limit you to this
now to do this speed you will need a whole lot of power but it is what the book says

I've gone somewhere between 135 and 140... so i guess 137mph in my stock TII. The only reason I let off was because I have a bad tranny mount and thought the tranny was gonna drop out from under me. Plus the vibration was really starting make my nuts go numb
