It really doesn't matter. I've been to every Powercruise at ECR and whether I was entered or not I had a ball. Here's what it comes down to, Steve;
You pull out of pit lane like you have done a heap of times before and as soon as you get onto the racetrack proper, you pin the throttle and aim at turn two. Sounds just like any open race day, right?
WRONG!
And it's all because you have three of your buddies in the car, giggling like school girls and loving the fact that they can enjoy your car just like you do. Then there's the racing. The rules allow for roll-ons where you can line up your buddy in his car and give it a squirt in the designated areas (just about everywhere). It's the most casual, enjoyable way to enjoy your car with your mates you'll ever have.
The dyno comp is usually dominated by massive dollar cars but that doesn't stop people sticking their 200hp stockers on the rollers. At the end of the day it's about putting on a show for the punters and the crowd really appreciate tough cars.
You WILL love it mate. I personally guarantee it. Don't worry about 'competing'. That's the tiniest part of this event.
