If you really want to go fast, and not want to have to engineer anything (like Nic Case did) that's the way to do it. Jimmy Schauer has gone 108 with his dragster with pretty much off the shelf components.

Other than that, you're either looking at a 1) shorter wheelbase electric lipo powered car or 2) a nitro powered car, of which only two or maybe three in the world have ever hit a real 100 mph, and those were high-dollar purpose-built unlimited speed run cars. Fact.
