mc28 barrels aren't quite as good, the CDI is probably a litle bit worse for ultimate power on UK pump fuel if running the 030 card vs a spliced PGM-III (remember neither are intend to run on 95/97 or 98 RON unleaded), carbs are different (I'm not saying better or worse, just different). Ultimately if you take it on track the mc28 chassis is not as good.paul wrote:with an hrc card can i expect similar results to a 21, or are there other hold backs?
Lots of little bits all add up
