1999 Ford F-150 Lightning Kenne Bell Blower Swap
Intercooler Efficiency @ 522 HP
We have praised the efficiency of the (late-model) intercooler system employed on the Lightning and for good reason. Check out the results of this test. We all wanted to see just how much power was available from the Autorotor and since the air/fuel ratio (also data logged) was nice and safe (usually about 10.5:1) we decided to really get serious. The motor was equipped with what we dubbed (at nearly midnight) the "Ken Super Tube"(a large section of 4-inch aluminum tubing used to keep fan wash from upsetting the filter). The tubing was attached to the 90mm meter and the stock flexible section of tubing used to join the MAF to the throttle body. We used the AccuFab prototype throttle body and equipped the supercharger with a 2.57-inch blower pulley. We continued use of the 9 inch crank pulley from Johnny Lightning. So equipped, the motor ripped out 522 hp at the wheels and a whopping 600 lbs.-ft. of torque at the wheels--through the stock cats no less. What was real impressive was the fact that the charge temperature at 21.6 psi reached 320 exiting the blower but was reduced to a peak of just 106. The stock intercooler system running ambient water (no ice water tricks) pulled out over 200 of charge temperature. I guess Ford suspected Lightning owners might be subjecting their trucks to some abuse. View Related Article
