Lockdown Engine Run - ASP S15A

Engine of the week: ASP S15A. I used this engine in Slow Goodyear team race for several years until it lost its hot starting prowess, so now it's retired and waiting for a new job - possibly Slow Combat. I usually ran it with the venturi closed down to about 5mm, on 10% nitro, suction feed and an APC 7x4 in Slow GY. This run is in the unrestricted mode, 6.5mm venturi, 25% nitro and crankcase pressure.
