Unfortunately I do not have a torque chart. However, it is possible to calulate the rate of torque falloff. I do not have the figures for that either. I do not it drops rapidly about after 5,000 RPM. You are right, with a factory camshaft you would never be able to do 8,000 rpm, that figure was thrown out the to illustrate that a K&N cannot give you more power in this application, because even the paper filters far exceed the airflow requirements of the engine, and you would need to be revving outrageously high to even come close to useing the OEM potential.

I odered a camshaft in Zaporojie Plane motor plant and they made a shaft with optomal on their opiniton valve timing (21d after TDC intake valve closing). I payed $150 for it. They told me, that now I have 194 HP motor with 88.9 mm pistons and 208 with 96 mm. I belive 194 HP is enought, but I had to modify exhaust.
