Review on Revolutionary Motor: Transforming Efficiency and Performance by Ronny Welch

Revainrating 1 out of 5

Problem solved - engine cooling and air conditioning

I wish I had bought this 3 years earlier. I couldn't figure out what was making my car tick until we took it to the dealer and sure enough dealers love to rip people off and would charge us $150 for the part and $500 for the labor. Luckily the guy is a car enthusiast and after telling us what was causing the tick was able to switch it over fairly quickly, saving us literally hundreds!

Pros
  • GOLS certificate
Cons
  • So-so
