VP & Sunoco Race Fuel Cross Reference

[Tracy Robbins]

Rockett 111 would be equivalent to C-11. Lee Nylander @ Rockett is a wealth of knowlege. He answers their tech line check out www.rockettbrand.com for an 800 number.

I dyno'd with C14 (What was available at the time) in an SS 427 Alum headed motor, so would I have to richen the mixture to go to C11, Rocket 111 or Sunoco Purple? Not going back to the dyno anytime soon to test fuels. I assume I can get an idea on what to do by viewing my EGT temps after a run?

curious, did you optimize timing and jet w/ C14? which burns slower than C11? If so than you would have to run more jet and less timing to achieve the same burn...make sence???

Makes sense. We optimized the timing and jetting with C-14

Thanks!
