it made 478 rwhp with 175 wet spray the ls1 is one fine peice of alloy micks motorsport highly recommended
Very sceptical of that power figure. Even if the kit added a true 175hp at the tyres, thats still 303rwhp, out of a stock LS1? Doubtful. Nice power though regardless, 175 is a decent hit either way.
dyno figures bumped up maybe? standard ls1 is 346cubes, you have managed to gain 356 which isnt stock mate.
