RPM for a Banshee
 

I have several buddies running the T-5's and I believe they are the best all around pipe you can buy. If we didnt race so much I would trade my CPI's for a set.

what makes the T6's so bad when you are doing major mods

The best I can explain is that the expansion chamber is designed for the stock exhaust duration. When you go modifying the exhaust port you change when the pressure wave reflects back to the cylinder. If the timing isn't right then power is no good. I ported a set of jugs to my standard all around port that had a set of T-6's on it. The power was great until about 3/4 up the rpm scale then it went flat. It wouldnt rev out good. We did nothing but put a set of T-5's on it and then it really woke up. Power down low was the same but screamed on top end. If you notice every set of T-5's that go on e-bay sell for a great price because people know they work.

Are you sure a banshee cant pull more then 8500RPM stock? its such a tiny piston? In my manual it says my LT can churn 9000 RPM!

I'm sure it can turn more rpms than that, but where does it make it's actual power? Chances are at around 8000 it falls off bad.My bike made it's max power on the dyno at 9200rpms and went flat at 10,600. It is definitely far from stock.

i get what u say, maybee you can pull upwards of 9k in 1st-2ed gear, but the motor has a hard time holding that rpm. Thx for clearing it up.
