I am wondering how I get more rpms. I asphalt race at 4600ft. 1/4 mile. I am only getting 7800 rpm I was told 8500.

The motor is all stock and stock pipes. 22-37 gear stock clutch weight w/rivit w-s-w spring,stock secondary 47degree helix.

The sled rus pretty good, 3 races 3 finals 1 win, nice points lead.

Thanks Ray
 

1/4 mile is 1320ft. your 4600ft is a little over 7/8 of a mile, try taking the rivit out of the weight and maybe tighten up your secondary a little.
 
RAY. LIKE TO SEE YA WITH A AGGRESSIVE ANGLE CAM. ANYWAYS DON,T RUN AT 8500. 8350 IS SWEET SPOT. NWC IS SPOT ON, TAKE YOUR WEIGHTS OUT AND DRILL TIP RIVET OUT. RUN THAT EMPTIE. 3:16 (yammie tony)
