I run this engine in buggy and is flat amazing power. It wheels truggies really nice aswell. Get it you wont be dissapointed. Half these guys on here saying they like werks never seen or ran a dynamite and think the name is cheap so the engine is and thats where there wrong. Ive seen more werks junk out its a joke. Werks are nice but i really love my dynamite more. plus since you got the money for it and a pipe snatch it up i will gurantee that you will love the power this thing offers. I still havent passed 220 on degrees and the power is nuts, considering 250 is where it really likes to run, I still got a big window of power to open it. also before im bashed on the werks area im not saying they suck they are really good but i have seen 2 werks a b5 and b6 not reach 2 1/2 gallons. The b5 was the updated one and out of box junk carb then went to totally dieing 2 gallons later the b6 ran really good but didnt hold compression. Now for dynamite ive seen a just broken in get stuck at full throttle till it died and only lost the rod. Senn another in a losi get stuck in full and did no harm. Cant compare but the dynamites are just rock solid. I can go on and on about the good in both but for a beginner and club racer its great. I love my dynamite others love there werks. Just like a car for example some love there hondas but i love my idk dodge or somthin. There are always fan boys but ur guts saying xpe for a reason! lol
