gomer Posted March 2, 2004 Report Posted March 2, 2004 hey guys i have a 2003 yamaha banshee with t-5s and the toomey jet kit everything perfect with the jetting it doesnt bog anywere in the rpm range i was wondering how many horsepower i am getting any help would be great Quote
MotulMonsta Posted March 4, 2004 Report Posted March 4, 2004 I'd say around 53-57 as the stock puts out 45-50. Get it on a dyno Quote
jonnyrebel2004 Posted March 4, 2004 Report Posted March 4, 2004 Looking at what I have described below what would you say my HP is? Thanks Travis Quote
MotulMonsta Posted March 4, 2004 Report Posted March 4, 2004 About the same 55-58. Posible 60 due to the higher compression ratio of the domes as opposed to stock head. I'm mearly guestamating. You figure about a 10-15 hp gain for pipes alone then add 2 for compression boost..the other stuff is junk. Maybe 1-2 for reeds Quote
lian Posted March 4, 2004 Report Posted March 4, 2004 how much hp would you get if you had fmf fatties with power core 2 and have twin air with no lid and 4 degree key and what hp difrence do you get if you mill the stock heads Quote
MotulMonsta Posted March 5, 2004 Report Posted March 5, 2004 It's not how much it will make, but where it makes it at. Toomey is a top end pipe, all the HP gains are up top in the higher rpms. the gnarly's or fatties run a broader power band..but peak HP numbers are lower then toomeys. But they make more low-mid hp. Depends on how you ride and where you ride. I wouldn't recomend gnarlies for wide open desert and fire trails..but then again Toomeys require serious clutch work to keep on the pipes in the woods and tigh trails. Real HP gains are made when you start bumping up the compression. But the higher the compression, the higher the octane rating you'll have to run. So there is drawbacks. You can mill close to 20 thousandths off a stock head and still run pump gas..any more and it will start to knock..meaning you need to run a better gas. Quote
gomer Posted March 5, 2004 Author Report Posted March 5, 2004 yea i love my t-5s as long as its long ans strate other then that they blow but im advancing the timing +4 this weekend and in a few weeks im goin to send the head off th have it shaved Quote
lian Posted March 5, 2004 Report Posted March 5, 2004 thats pretty cool i knew all that stuff but im really cures what my hp is upto cant get it off my mind and theres no one else to turn to but you guys Quote
2004LEBanshee Posted March 5, 2004 Report Posted March 5, 2004 I'm sorry but I seriously doubt that your getting mid 50' hp just form pipes. Id say 40-45 maybe. Quote
Labarraca_Baca Posted March 5, 2004 Report Posted March 5, 2004 yeah i agree with 2004LEbanshee pipes do add a good amount of ponys to the horspower but not that much. id say some where in the high 40s Quote
MotulMonsta Posted March 5, 2004 Report Posted March 5, 2004 A stock banshee motor dyno's at about 43.5 hp. Here's Toomey's dyno results. Stock banshee w/ their pipe and jet kit Quote
