You'd hand it to me in the 1/4 mile for sure. Diesels don't make the best 1/4 racers with the gearing they've got. BTW, the GN is one of my all time fav cars. I remember seeing those cars as a kid and just drooling.
With my current tune I've pretty much maxed out fuel and the turbos (33psi at WOT). As you know the more power you want the more expensive it gets, lol. Methanol is next and will give me another nice bump in hp.
Got any pics of that GN?
