Stage 2 HDI vs GTI6 In Gear

[ally406]

Regardless of which is quicker, a petrol can have other advantages around a track. Controlling the attitude of the car with the throttle or balancing the throttle mid corner is so much easier on an NA petrol, and a broad rev range helps and means you aren't grabbing a gear at the wrong time. You're talking stock power versus tuned, when you batter an engine all day reliability is going to be a big factor. Another common problem with turbo diesels is that power can drop off during prolonged flogging, an NA petrol generally returns similar performance lap after lap. I'm talking in general terms and I don't know much about tuned HDI's, but my point is outright power is not always the priority.
