This "race" had better be at a dragstrip. :squint:

That said, it's going to take a fairly radical N/A setup to dust a V-8 Mustang on the dragstrip. Not to say it's impossible, but I question how well such a setup would fare on the street as a daily driver. The cheaper way - and IMO more entertaining way - to beat a Mustang would be to challenge them to a NASA or SCCA auto-x. You'll wipe the floor with them with little more than a decent set of tires and a few suspension upgrades.
