INTRODUCTION: Development of our fuel injection racing book and our methanol racing book included information from drag race competition & testing. Several test runs with our supercharged drag car were recorded in home videos shown below. While a lot of camera movement & view interference is throughout, these videos are indicative of reliable performance levels from the various moderate setups in our drag racer. The test runs were done with either a streamline nostalgia Corvette funnycar body or nostalgia altered body with an aerodynamic nose piece & adjustable wing with spill plates.
SOFT SETUPS: In all of these runs, both the setups & operation were held moderate for the best reliability & repeatability. They were not anywhere near the maximum power output available from more blower overdrive, more launch engine speed, more shift engine speed, air to fuel ratio leaning, or more nitromethane. We ran our own ‘race of technical publications,’ not the competitors’ ‘race of max engine power, fastest ET, or max speed.’
JETTING: The fuel for each run was either methanol or nitromethane blends with methanol. Jetting was properly adjusted with data from our calculator, Pro-Calc, for optimum fuel distribution, low speed air to fuel ratio, high speed air to fuel ratio, & fuel pressure. The notations with each of the following video llinks show other details of the test run.
VIDEO 1 ALT: Red altered during the day on methanol; low blower speed (underdriven) of -10.3%; low engine RPM leave; low RPM shifting.
RESULTS: Straight run @ 7.56 ET 184 MPH with an even color on all spark plugs; engine temp between 150 & 180 deg. F; this was our typical soft setup for Nostalgia Eliminator One with a bracket ET target of 7.6 sec. It was also similar to the mechanical setup used with our nostalgia Corvette funnycar body in CIFCA bracket racing with an ET target of 7.5 sec.
Video currently not available.
VIDEO 2 ALT: Red altered at night on 6% nitromethane 94% methanol; using our Pro-Calc, we adjusted jetting & nozzles to a specific air to fuel ratio discussed in our publications that was necessary for a low percentage of nitromethane. It was set up also with low blower speed (underdrive) of -10.3%; low engine RPM leave; and shifting @ low engine speed in the 6’s RPM. This setup is detailed in Blown Nitro Racing on a Budget.
RESULTS: Straight run @ 7.30 ET 193 MPH again with an even color on all spark plugs; engine temp between 150 & 180 deg. F; this was the start of our low percentage nitromethane development.
VIDEO 3 ALT: Red altered during the day on 20% nitromethane 80% methanol with Pro-Calc jetting & nozzles; -10.3% blower; low RPM leave; low RPM shifting; with jetting & nozzles adjusted for an appropriate air to fuel ratio. This setup is also detailed in Blown Nitro Racing on a Budget.
RESULTS: Straight run @ 7.02 ET 196 MPH and again with an even color on all 8 spark plugs & good engine temp.
Video currently not available.
VIDEO 4 FC: Funnycar on a day run on methanol; 11.5% blower over drive; low RPM leave; shifting 7600 RPM.
RESULTS: Straight run @ 6.74 ET 205 MPH with an even color on all 8 spark plugs and a good engine temperature.
VIDEO 5 FC: Funnycar during a day run on methanol; 15.4% blower overdrive; low RPM leave; shifting in the high 7s RPM.
RESULTS: Straight run @ 6.69 ET 205 MPH with good plug reading & engine temperature.
VIdeo 6 FC: Funnycar during day on methanol; 19.2% blower overdrive; IDLE launch; shifting high 7s RPM.
RESULTS: Straight run @ 6.68 ET 209 MPH with good plug color and engine temperature; while the blower was above previous tests, is was still well below values for maximum performance. Again the intent was to maintain good reliability for continued testing & bracket racing competition. Also note the rapid response from an idle launch. At the hit, I swapped the clutch & throttle feet, full loading the engine at idle on up.
