There is no ratio for that, when setting up gearing it is a comparmise between the 2. It's best to ask ur local racwers what they are using. On the longest straight at your track you want ur engine to hit maximum revs just before the end of that straight. Preferably no more than a 5 tooth split with pinions, or the engine will bog down when changing.
Which one first? Set the high end gear ratio (2nd Speed) and than get 4-5 split for the first gear. Or any other thing that we should consider?
