lokisbuddy Posted February 9, 2009 Report Posted February 9, 2009 Ok guys I was watching horsepower tv the other day and saw this bad ass lsx engine they built. they put it on the dyno and I cant remember what it ran but then they put on a carb spacer and it gained 18 horse and 8ft lbs of torque wouldnt this same principle apply with reed spacers I mean to a lesser extent? could someone with access to a dyno please do a study on this? thanks Quote
BlasterKX Posted February 9, 2009 Report Posted February 9, 2009 I dont think it would do anything like that on a 2 stroke cuz we use reed valves. on a car engine they use of course valves cams etc etc. anyway i beleave that a spacer would just push the reeds further away. but i could be wrong if it doesnt do anything. someone please correct me if i am.lol Quote
lokisbuddy Posted February 9, 2009 Author Report Posted February 9, 2009 I have never really felt any gains using the reed spacer but I want dyno proven results to finally lay to rest the whole issue lol Quote
Snopczynski Posted February 9, 2009 Report Posted February 9, 2009 Reed spacers do make a difference for the good on larger bore, higher cc 2-stroke motors. Stock and even in some cases mini strokers, its not a high gain. Quote
jinx44 Posted February 9, 2009 Report Posted February 9, 2009 I have spent several hours in the past on the dyno testing reed spacers with 350 and 4mm motors. I tried at least 4-5 different thicknesses, and tried reed/cylinder, and intake/reed combinations. I found more power decreases than increases, and never saw a significant enough powerband shift to constitute the money and time spent. If you want to try them for yourself, I have a few sets still laying around here. Quote
VWMIKE Posted February 9, 2009 Report Posted February 9, 2009 I think each application is different as well. I think it depends on how good or bad the stock intake tract is designed. On older Honda Cr250's it sucks, and running a reed spacer made a noticeable difference in the way they ran, especially down low. Quote
LS1Inferno Posted February 9, 2009 Report Posted February 9, 2009 the only reason for running spaces ive seen is to just mover the carbs up and out some to keep from bowls hitting the clutch Quote
BlasterKX Posted February 9, 2009 Report Posted February 9, 2009 the only reason for running spaces ive seen is to just mover the carbs up and out some to keep from bowls hitting the clutch thats what i have always seen when it comes to this topic. and if theres so many people saying that then apparantly its true.lol Quote
RollinRhino Posted February 10, 2009 Report Posted February 10, 2009 Spacers on a two stroke reduce volumetric efficiency, whereas on a four stroke they can be used to tune the engine's intake capacity. Quote
