Dyno Vs.Drag Strip Testing

Indeed a testing tool for AFR, total timing etc.etc. UK dyno's however seem to be quite good for accuracy against real time track results.
2 examples, a known [email protected] ran 137/weight came out to just 4hp less.
And our own '69RR dyno'd@695fwhp, to date we are @664fwhp per weight/mph with same carb, settings plus a full exhaust, with a bit more left in the car.
