if its a COMPLETELY STOCK CHEST. it will fall about that 8K mark.. as will Stock switch boxes... stock chest stock tuner etc stop scavenging about 7600


between the two i think you may just need to spend some money

No chest work is allowed to be done in these configurations.

These motors regularly turn 9200+ as well as 200xri.

They have 56lb fuel curves and one piece plates and tuners.

Thats all I can figure is really holding me back now is ability to turn fuel down in this heat and the adapter plate/tuner?

what about exhaust divider? Are the promax and 260 the same?? Both mine look identical to me??
