How fast will a ZHP go?

[Gheybe]

The fastest I've been is 110 MPH and I felt like a complete ass after I pulled that off.

Its limited to 155 but with aftermarket software that removes the limiter, I believe some people have seen the lower 160's on a GPS.

I know I don't have a ZHP, but I have the same differential as you guys with a manual.

But I got to 162 as per the GPS.

When I was back in Germany (on 9 Munich to Berlin) I had my speedometer maxed out at +/-155 mph, and the limiter never kicked in, while the Tach showed only around +/-5800 RPM. There was not much more gas pedal or oomph left in the car, you can feel the car was already at the drag limit.

i hit 125 once but then quickly went back down thinking it was at its limit but now i read this and have plans.

My car felt very stable and felt like it wanted more when I hit 140 last year. I have no plans to do that again.

Are you sure that limiter wasn't cutting power? That's a lot like what the limiter does; cuts power and it feels like there's nothing left. I'm willing to bet that if you had some performance software that takes out the limiter, you'd see an easy 270-280km/h if you give it some space to stretch its legs.

Yes, I'm fairly sure about the limiter not cutting in. I did it few times just to make sure I actually maxed out the speedo. Now, if I kept it there for a while longer I guess I could have gone a hair faster BUT it was very slow from about 150mph on to get to a hair past 155mph mark on so I think it was very close to the top end (+/- speedo error). The real surprise was that the RPM was still fairly low for the top end, so maybe if I droped the gear down one. I did have my DME software reflashed/updated at a German BMW dealer during my tour when I used to get the engine ck light after normal autobahn driving. BTW, I am going back this summer so I should be able to duplicate, although this time I am adding a turbo.

Great line. I'm stealing that one for future use.

LOL def gonna use that as well Great line, Eduardo!

As for me...I've had the 328 up to 127mph gps confirmed. Just a mile/hour short of the limiter kicking in Need to get that removed for future activities...
