I have a new Nova P5XLT on a Kyosho inferno MP9 TKI 3 Ready set.......I have about a gallon threw it. I am running Kyosho 1.1 Clutch Springs, Kyosho Blue clutch shoes, 13 tooth bell, 46 spur. Nova 41021 Manifold, Nova 9901 SS Pipe. I have run both the 6 and 6.5 carb inserts with similar results.

The low end in the motor seems somewhat lacking. I am not the greatest tuner but I think the tune is close. I am wondering if my pipe & manifold selection may be having an adverse affect on the low end power I am looking for. The motor has plenty of top end! I run down most cars on the back straight.

From a dead stop the car is hooked up and you can hear the clutch engage but there is a flat spot in the power band at the point of engagement. The motor is not coughing and belching out smoke as if to rich.....it is not sputtering and missing out as if to lean.

I have gone over the clutch it looks good and all the shoes seem to be engaging correctly. Like I said above I am of the opinion that I may have a bad Nova mani / tuned pipe combo for the application. I don't want to sacrifice all of my top end power for low end power but I could definitely trade some high end power for some low end grunt.

I'm not the greatest driver so I know I don't carry enough speed threw the corners which drops the motor out of the power band......so my driving style is such that I go threw a corner rite before a jump and with the flat spot in the power band I come up short on most jumps. OR on a good night I carry enough speed threw the corner and over shoot the jump
