I have the chip, fuel controller, throttle body reworked and it runs 54 on 12' beadlocks and Interco Reptiles. the first throttle body james put on would run to 59 but didn't run as smooth as this set up. I was happy with the first TBody but James wasn't and he swapped it out, no cost. although I lost 5 mph the power is amazing--torque, torque, torque at any speed. unbelievable torque. acceleration is excellent up to 45 and tappers off slightly after that. the most linear power transfer I have seen. alas, although I am happy with the set up, I walked into james office and there sat the most gorgeous polished and ported head and glistening piston that just screamed "JET_JET_JET". how could I resist and of course, must have the alba exhaust-----lol. sooooooooooooooo the rhinojet is 200 miles from home in the ever capable hands of the HRR and will be ready, when james is happy with it. lmao.
