Shee-Male Posted July 4, 2005 Report Posted July 4, 2005 Ok I'm really in a indecisive bind here, I going to do the rz conversion on my banshee but I don't know what pipes to run. The thing is the rz motor is way differant than the oem banshee motor so I don't see how a "banshee pipe" would be sufficient, I may even loose hp? not to mention what happens after porting, expansion chamber size is critical, so what I'm wondering is if there is some sort of formula or software that can tell me what direction I should be looking in? Dose anybody have dyno charts, mag articals or know of a acctual rz bansee pipe? or a shop that specializes in this? What to do??? Quote
bigford84 Posted July 5, 2005 Report Posted July 5, 2005 i know of a guy that has a RZ shee with pipes on it ill have to give him a holler to see what he has. Quote
rzcolobanshee Posted July 5, 2005 Report Posted July 5, 2005 RZ motor is not "way different" the exhaust port is a lot higher, that is the main difference. I'm running Toomey T3's with 2" cut out of them, they rip very hard but have no low end. The only pipes I know of that will fit without dents or cutting are old style fmf's, paul turners and Rockets...or any out of frame pipe will work Quote
cbn70 Posted July 6, 2005 Report Posted July 6, 2005 the old style FMF's?? Where can a guy find a set of those?? I never heard about those clearing the power valve on a RZ powered shee Quote
Shee-Male Posted July 6, 2005 Author Report Posted July 6, 2005 Na, even old fmf's hit. I'm not trying to determine what fits I,m trying to find a "proper" pipe, "it rips" dosn't tell me anything, have you dynoed it? besides a rz motor is way different, sure there both 350cc's but there is nearly a 20 hp differance, a two stroke is way different than a 4 stroke because of the expansion chamber, if you cut out 2 inches out of it what happens?, how about 2 & 1/8? or what about 1 7/8? why 2"?. I guess what I'm trying to determine is chamber volume and try to match it I only whant to do it once and properly! I don't whant to settle for close or good enough. Quote
rzcolobanshee Posted July 6, 2005 Report Posted July 6, 2005 I was told the old fmfs cleared but maybe I was misinformed. I have not dynoed it but I was racing my cousin this weekend and he has a 7mm cub and I was keeping right up with him. What does a 4 stroke have anything to do with this? I know what pipes do on 2 strokes ass monkey. Cut T3's are one of the best drag pipes there are for gas (not so good for alcohol, scavenging sucks). The more you cut out the more hp you gain (up to 2.5") but you lose low end the more you cut out, it's up to you if you want the most power or keep it duneable. If your really looking for the most power you can have Shearer or GRR build you a custom set based on your porting Quote

rx7500hpt2 Posted July 7, 2005 Report Posted July 7, 2005 The easiest pipe to run is a pual turner. Quote
