Welcome to Drive Crash Repair Repeat here you can find, RC Cars, Losi , 30dnt, BAja, hybrid, RCmax Engine RC cars. Lots of bashing and crashes but most of all good fun.
I've been involved in High Performance automobiles and also drag raced 2-stroke ATVs for decades and you have it all backwards on them stacks...the stack with the wider opening will bring in more air volume into the opening and thusly create a faster and more dense air charge...the OBR starts small and stays small, not much of a chance for compressing the air and speeding it up...take it from me, the OBR will NOT perform as well. You see, in order to sell stuff, all these manufacturers claim big and give these parts catchy names in hopes people fall for'em and buy their product. So I bet if you put both of those on an airflow meter, the OBR will absolutely flow less...
I love my Traxxas Slash and my rustler VXL brushless but nothing compares to my big 1/5 scale King Motor blade 34cc 2-stroke and the Rovan XLT 45 four wheel drive behemoth the sound and smell you can't get from Electric. Those sound nasty
