Kevin You've got some other issue going on there ~ I live @ 5006'FtASL & do most of my driving @ or above that & Back when my 90Westy had a H2Oboxer BelowDeck it would do 80MPH when ever I asked it to as long as the Terrain was RelativelyLevel & the Winds were Light ~ There is a loss of about 18% in HP @ these Alt's so it does take longer to get to speed but somewhere @ least in the 70s should be achievable if your Van' is healthy.
