Saltfever, i just replied (quoted) to your post #10. ( which quoted 8 ) I Felt most of the discussion was a bit confusing, which has been a problem in other threads with the Classic Category and how it is different. Of course, an ECU is not
required to run in the Modified category as you say. As long as the car fits the appropriate CLASS rules in "regular" Modified you can run whatever you want. And I am emphasizing Class rules here= the various NA, blown, fuel, gas variations of Alt and GC. Classic CATEGORY also includes all these classes as well as Production. Sorry for any confusion. However you mention and equate "modern" with Modified and that any induction is allowed. Mechanical FI is allowed in Classic as well as CDI and magnetos (single). These parts are not different in the two Categories. Specifically again "For reasons of economy and historical authenticity,
certain electronic engine technologies are not allowed " and other than vintage bodies ( 1928-1948) this is the only substantive difference between Classic and Non Classic. Considering the long debate about which makes more power (in our case WFO,( not fuel economy, emissions or around town driving) a carb or EFI or MFI for that matter, there should be no significant power and therefore record speed differences between the two categories. I opine that if your ignition, whatever it is, lights the fire, there is no reliable power difference in how you make it. l guess another arguable point as some may light the fire better than others. But there are AERO differences of the cars between the two categories so the records in Classic haven't caught up yet.
Again, sorry if I wasn't clear and hope this was better. Trying to be helpful.
