How many horsepower does a car need to cruise at 65 mph?
Enjoy. People find it difficult to believe that their car only needs about twenty horsepower to cruise along at a steady 65 mph. Here’s how you can check for yourself. You’ll need a stopwatch, a good, flat, empty road, wind-free conditions, and at least one passenger plus the driver.
What should the RPMs be at 75 mph?
I know this question depends on the engine and how it’s set up, but what would be an “ideal” rpm range for cruising the highways at 75 mph with a 350 sbc? Ideal being good gas mileage and the ability to pass without a downshift (if those two aren’t mutually exclusive).
What is the Max RPM you run your motor at continously?
As a point of reference, a Suzuki DF140 will run around 37 with 1/2 fuel and 2 people, per Suzuki’s performance sats. The BF150 is a more powerful engine and should easily add at least 4-5 mph to the Suz’s top speed. I wonder if you have barnacles or something growing on your hull?
Can a 4.2 liter TPS stay locked at 50 mph?
A TPS is also possible, but I bet it’s just worn with knowing you’ve had it eight year’s and it’s high mileage. The 4.2 has plenty of power to stay locked at 50 – 60 mph, even with the car full of family & stuff and even on slight inclines.

Can a 4.2 liter engine go to 60 mph?
The 4.2 has plenty of power to stay locked at 50 – 60 mph, even with the car full of family & stuff and even on slight inclines. Actually, on a few occasions I was amazed by how much “suffocating” the engine took before the computer decided it cannot go locked anymore.

Do you need to change gears at 60 mph?
To raise the rpm at 60 mph (or any given road speed), you need to gear “lower”, i.e. the 3.42 gears will need to be changed.
