When my neighbor let me borrow his Dodge ram 1500 quad cab, srt-10. (basically has a viper engine in it) I was going 145 mph and honestly didn't think i was going that fast. I was cursing with around 3,000 rpm.
In my everyday truck, 07 doge ram 1500 quad cab. I get it up to like 125, every once and a while to shake the cobwebs out.
But the same neighbor took me 160 MPH in a 35... probably the most exhilarating thing i have ever done. He had the only White with white rims viper in the world. (know to the viper club) It had a blue racing strip and was so fresh. Since then he has sold it.
