went to the track last night hoping to get into the 8's on the 100shot. Well i go pull up the tree. stall it up to 2000rpm flip the arm switch and purge the lines.

okay now it starts to suck. launch!!! and then total BOG ... BOG... BOG until about 2700 rpms... then the f'er starts haulin ***, but my best 60' out of the night was a 2.59 due to all this bogging. I have the FJO programmed to come out of the hole spraying 40% of the shot to 2500rpms then it goes to 80% then 100% from 3000rpms on.... did this all three runs.

second run i have it @ 25% out of the hole and still bogging...... everyone one was running really slow last night my best run was a 9.7 @ 72mph which sux considering my best a 9.2 on a 75 shot....... can anyone give me a reason for this?

 

There aren't a whole lot of ppl spraying under 3,000rpm's....so might have some issues with the mixture. Bog is usually indicator that there is fuel and no nitrous, or super rich.

 

that doesnt make any sense though. i purge..... and everything.... hmmm

 

what does that have to do with what he said???
he meant no nitrous being sprayed into the engine, like you fuel solenoid opening and your nitrous solenoid not opening.

 

Dry our wet system?
Does your progressive system work on both fuel and nitrous solenoids or just a nitrous solenoid?
