We added a gutted maxima intake and OBX headers and went back to the dyno today. The results are impressive. While peak only changed by 5hp, we picked up 30hp on the top. In a race car, thats massive. Anyone who races and doesnt gut the plenum is missing out. Considering we have only wiseco pistons, NWP spacers, and revup cams, the rest of the motor is essentially stock. Suffice to say I am happy with the results. Many thanks Aaron, UpRev and Z1.
Next event is next weekend at Barber Motorsports Park.
