tonight i did a WOT run in 3rd and noticed my duty cycle at 82%. i have motron 60s with 58psi with 0 vaccum. this was at 15psi of boost. fuel system is dual 255s -8 feed -6 return. does thsi sound reasonable? also is there any reference to HP that is being made with this much duty cycle on properly setup fuel system?

i get mine to about 95% idc when only running boost at 15 psi and also using a bit of meth. id say thats about right, i dont have a big motor only a 370 so with a 4.8 id guess thats a about right, my fuel pressure is 58 psi boost referenced. so at 15 psi boost the pumps are actually making 73-75 psi .

i didnt hink that the 4.8 would use that kind of duty cycle. but i guess in the case of turbo size of motor doesnt matter all that much. this thing is violent
