Long overdue update;;
I went from a 108 bypass with 38 nozzles to a 100 and gained .14 et from 8.90 to 8.76 with about a 2 mph gain, log book is not available to me at the moment. In the end it was hard to race with due to fumes. On one pass my eyes watered so bad i should have aborted. For years (1999 to 2009) running methanol and Klotz i got by with just filling the system and not draining it for storage. After playing with m5 for four years all my AN fittings were junk. So if you run it drain the m5 after the race weekend and be sure lines and all are clear of fuel.
