Im wondering who would win this race. I have a 87' N/A and I have raced a few of the MKIV's around my area and beat them. My car has no mods or anything on it so Im wondering why Im winning against newer cars that have like 20 more HP than me. Do the MKIV's way much more than an MKIII or is there something else?

Honestly, I really don't know why, could be a number of things. Gear ratios, weight, or driver. The list can go on, but keep it up, sounds like you have a good run going.
