I got my new R8 engine friday and again the break in was great, this engine Rex lapped for easy break in and he also did his work on the crank to get a little more rpm from it. I had it broken in and ready for the track saturday to finish the running in and to get it tuned and ready for the Dual race this coming weekend at the Proline test track and Thunder Alley Rc tracks. By the end of the night I had about a half gallon through the engine and had it tuned in with a 6.5 insert. This R8 is some serious power, it has a ton of bottom but with Rex's mod to the crank it never stops pulling. It blows my mind that these engines make so much useable power at this price point, I can honestly say I have not driven a car with this much power at any price. I am not 100% sure how much top end the stock R8 has but with just minor crank timing adjustment I can say this motor makes enough power to put a smile on anyones face. In my opinion most guys will find that the D52 power band for buggy is spot on especially if you dont have great grip at your track, but if you want a motor with more power from bottom to top look at the R8 modded by Rex. This is my first modded motor as I have always been hesitant because many modders over do it but this motor has a great idle and is power everywhere with no dead spots it is ultra crisp response. I will have a busy weekend at the Dual and it is an out of town race for me but I will do my best to get some video on a couple of the best layouts you will ever see. Thanks Rex and RW mods this thing rips.
