Ryan Lopez, Corey Johnson, and Gene Hickerson have been testing this fully modified engine since December with excellent results. We feel that we have found the best possible combination of power and fuel economy for the Arrow Engines. We have tested the Losi RE-12, OS T-2060, and VP-Pro RS-4 pipes and they all work well with these mods. Fuel mileage ranges from 9-12 minutes with a big increase in all around power.
Wow would love to see the internal when you have a chance. What type gains have you seen innreference of the power band. To date their aren't any arrows running locally so im clueless with its performance stock or modded. Im familar with the OS line been running Os for many years just recently swapped into nova line.
