My car is used as much on the road as on the track, so would have been having your cake and eating it scenario, as I could have had a huge turbo that didn't make good boost until 4500, and have the bottom end filled by the super-charger (this was the plan

).
In the end I compromised with a reasonably large turbo, the Mountune roller-barrells and shortening the gearing.
