No it doesn't get used on track and will only be running around 300 - 330bhp when i finally get it back on the road. I know it's not necessary but as im completely rebuilding the car and have the money to spend I like the peace of mind of knowing everything is going to be up to the job. I also have a large rad, 500 cooler and will be fitting a turbo cooler, all unnecessary but at least they won't be being pushed to their limits.
With the pas cooler issue I would use the standard cooler but mines getting a bit rusty and I can't find another one, I know people who have just removed and bypassed the cooler and suffered no problems so I know it's probably nothing to worry about.
