These are the dyno runs on the A15 in my Datsun 1200 done right after the 2007 Runoffs at Topeka. The engine is built to SCCA GTL specifications. It runs dual 45 DCOE Webers with 32mm chokes. Run #1 was done with the required 25mm SIR (single inlet restrictor). Run 1 was flawed by bad ignition timing, too much advance causing detonation. Run #4 was done with a 24mm SIR required on 4v engines. Run #5 was done without a restrictor. In reality, the power output for run #1 with the 25mm SIR should have fallen between runs #4 & #5 for output.
