10. Again averaging three pulls, we got closer to the magic 500rwhp goal with a 463/491 average, netting 40 more horsepower this time on 107 race gas and a slight two-degree-increase in timing (21 degrees). The interesting thing was that the downstream air temp readings from under the blower, actually went down during a full throttle pull (114 degrees at the start to 112 at the end of the pull), which is unheard of with valley-charged modular engines. This improvement is due to the location of the air-to-water intercooler coolant tank in the trunk—its four-gallon capacity with a 22-gpm Meziere water pump feeding 22 feet of heater hose routed under the car to the heat exchanger acts as an additional cooling device. We borrowed this idea from Brian Finch and his Pro-Touring Terminator-powered ’67 coupe (thanks Brian!). These numbers are safe, solid, reliable and repeatable.
