Here is one from my TC 426 motor.

TC 924 mx cam
TC Porting
39mm fcr carb
uni filter
Sparks x-6 pipe

The written number next to the hp is the torque.

If you have any graphs of your own please feel free to post them with motor mods.

Nice power on that 426.

I would like to take credit for it. But I bought the motor like that.

Where did you have it dinoed i live up in akron and saw you were from ohio just wondered if there was any where close to me that has a dyno.

[K_Fulk]

165 main 50 pilot, Ive never used the 02 sensor wish I did. But I think it was pretty close.

This is were I'm at 178 main 58 pilot needle 3rd from top. My
set up is Ross 88mm 39fcr x6 with spark arrester 21 plates
hot cam st2 (old type) curtis sparks filter an air box screen.
At sea level.

I would try going down. Being at a lower sea lever would make you run richer and also having the spark arrestor.

I probly could have went lower than I was.

I try a smaller pilot an it didn't start very well 52pj made the head pipe glow. And the main any smaller and it's like it stops pulling hard at the top. what elevation are you at. Also forgot the head is ported and has big valves an thin gaskets at the base an head.
