about dyno figues, there want any need to mention, that's a variable can be changed easily by changing ron levels.
In Pk dynos are never accurate due to differences on tuneups in street use and dyno garage.
Its about how much of car is left that can handle a quality drive and how well it was maintaned for a high reving motor. I have seen high dyno figure cars performing poor on streets due to unbalanced power/weight or unavaliability of proper maintanance.
