In addition to being plenty powerful, we liked the fact that the F-1A-94 was self-contained and required no drilling or tapping of the oil pan. The blown, injected big-block was tuned using a Holley HP management system and all testing was run on race fuel. The supplied air-to-water intercooler worked perfectly, dropping inlet air temps by over 100 degrees (using dyno water). The ProCharger kit installed without any drama, all we had to do was clock the discharge properly to line up with the intercooler tubing. To say that exceeding the 1,000hp mark was as easy as bolting on the ProCharger supercharger is an understatement. Enter the F-1A-94 centrifugal supercharger from ProCharger, which is the largest 9-inch supercharger they make. Looking to reach four-digit power levels with the BPE 540, we decided it was high time to apply a more serious power-adder. Little did we know that we were just scratching the surface of the power potential of the BPE 540, but we liked the fact that this thing just took each licking and kept on ticking. Run with the blower kit from Speedmaster and The Blower Shop, the Mad Adder produced 939 hp and 866 lb-ft of torque at 11.1 psi. Next up we applied some boost from a 6-71 supercharger (incorrectly labeled as an 8-71 in the story. Run with a 250hp shot, the nitrous injected 540 Mad Adder produced 937 hp and 891 lb-ft of torque. Having verified the engine was ready to rock and roll, we immediately applied the first of the power-adders in the form of a Zex nitrous kit. Also present was a healthy, solid roller cam that checked in with 0.652-inch lift with a 255/262-degree duration split and 114-degree LSA.Īfter receiving the big-block in the crate we ran it on the dyno in naturally aspirated trim, even though the engine came with a dyno sheet from BPE. The heads combine with the forged pistons to produce a boost-friendly compression ratio of 8.5:1. The forged rotating assembly was topped by a set of as-cast aluminum BBC (rectangular port) heads that featured 119cc combustion chambers. Starting with their own heavy-duty, four-bolt block they added a 4340 forged steel crank, forged H-beam rods, and matching forged aluminum pistons. We liked the fact that the BPE 540 featured plenty of intestinal fortitude in the form of forged internals. According to the info supplied with their crate 540 stroker, the BPE combo was ready for boost and/or nitrous right out of the box.
For those just joining the party, we have subjected our 540-inch big-block crate engine from BluePrint Engines (BPE) to two different power-adders: nitrous and boost (roots).
As loyal readers of Super Chevy, we know there is no way you missed the first two installments of our Mad Adder series.
