MeanHoTRoD_93883 Posted February 4, 2005 Report Posted February 4, 2005 Just asking My brother has a 2003 yamaha banshee its has T5S WHITE BORTHERS BOOST BOOTLE AND 2 K&N AIRFILTERS WHICH GO TO THE CARB AND ITS JETTED AT 290'S MAIN and with pistons it ran Maxpower 41.51 Max tourqe +22.26 Kmh/hr 139.65KMH MAXIMUM ENGINE SPEED 11.56 is that good for my mods or i need to check it is that fast for the mods my bro has Well he is unsure Quote
banshdog Posted February 4, 2005 Report Posted February 4, 2005 Kmh/hr 139.65KMH Or 86.8 mph. figured anyone who looked at this would do the conversion anyway, just lookin out. Quote
Ducman Posted February 4, 2005 Report Posted February 4, 2005 Not bad. Some port work will get your bro to 45 For comparison a YZF 450 with a full system and K&N lid off jetted makes about 43hp. Quote
richybanshee Posted February 4, 2005 Report Posted February 4, 2005 (edited) From what I know, a stock shee makes between 32-34 HP. Putting a K&N Filter properly jetted without airbox lid may get you to 35-39 HP. K&N info URL: http://www.knfilters.com/images/PowerSports/knpowerlids.jpg Some pipe manufactures claim 14-15 HP power increase over stock with box and filter mods. so 32 + 14 = 46 HP 33 + 14 = 47 HP 34 + 14 = 48 HP 32+15=47 HP 33+15=48 HP 34+15=49 HP From LRD site: http://www.lrdperformance.com/cgi-bin/shop...amaha%20Banshee Yamaha Banshee Banshee RFX Series pipes PEAK HP: 49.8 @ 8200 RPM WEIGHT: 17 lbs. From Toomey Racing: http://www.toomey.com/ They have Dyno runs of Procircuit, FMF SST's, Paul Turner MidRange, CPI's against their new TR6's. Every one of this pipes makes close to 50 HP. They do not display their T5's vs TR6's but I have the dyno sheet and T5's make only 47 HP. DMC claims 14 horse power http://www.dmc-on-line.com/index2.html CPI claims 1-3 horse power more than brand X http://www.cpiracing.com/support/faq/item.asp?id=13 If someone has dynoed a stock shee or with pipes and filter mod correct me if I'm wrong. MeanHoTRoD_93883 I think the banshee is a little low on power, based on the info I have collected. Edited February 4, 2005 by richybanshee Quote
OKsoccer24 Posted February 5, 2005 Report Posted February 5, 2005 I have the fmf gnarlies, 20cc domes w/pro design cool head, v-force and pro flow k&n. It made 46hp and was perfectly jetted. So you are probably right about the ball park of hp. Quote
MeanHoTRoD_93883 Posted February 5, 2005 Author Report Posted February 5, 2005 so i just need to check on the jetting? Quote
