Just my opinion: Don't mount the fuel solenoids on the fender. Mount them as close to the jets as possible. The nitrous has a pressure of approx 1,000 lbs. The fuel has a pressure of approx 6 lbs. If the fuel solenoids are to far from the jets, the time it takes for the fuel to reach the jets, will cause the system to be momentaraly lean. I have my fuel solenoid mounted right on the distribution block, and my nitrous solenoid mounted on the fender. Both solenoids mounted close to the jets is OK.
I usually spray about 175 HP, but have run as high as 225 hp. on stock pistons.
I'm not saying I haven't broken parts, but I get away with a lot.
