H2 top speed?
Hello,
I purchased my '03 H2 a few months ago. It tops out (speed) at around 80-85 mph. Is that about what other 03's do? Thanks.

Re: H2 top speed?
Thanks everyone. I figured something wasn't right. The motor runs smooth and doesn't seem to "miss". I didn't realize there was a governor. Thanks Again!

Re: H2 top speed?
There actually is not a governor but there is a top speed control built in to your computer that controls your motor, transmission, speedometer, etc. Unless you go to the dealership, you'll have to buy a programmer to access the computer and tell it to allow higher top speeds. 80 to 85 sounds low unless you have after market tires that are larger, causing the computer to go out of whack.
If the tires are larger, then the computer needs to be reprogrammed with a programmer, to make the changes. The programmer is a small handheld device that plugs into your vehicle under the dash, very simply. I use the Diablo Predator, but there are others available.
Hope this helps. Good luck.

Re: H2 top speed?
Thanks Gunzz,
I have the stock wheels. Right now the debate is to either take my rig to the dealer to see if there is something else wrong that would inhibit top speed or save the money from not seeing the dealer and buying a programmer to adjust accordingly. I'm just starting to investigate programmers.
PS. I like your ahhh.........picture! Thanks Again!

Re: H2 top speed?
I have had it right up to the 100MPH mark, definately seemed like it had some more left, cruising at 90-95 is no problem at all. You should be able to do 85 or better without hitting a wall

Re: H2 top speed?
You should go ahead and get programer. It will still unlock so much power and torque you will be amazed. It gives you control of so much like adjusting your wheel size in the computer to match what you are running so speedo is accurate.
