Quote: Awesome Mike! Would love for someone to show just how easy these can make power. One thing I have wondered about is how much power is a Drag Pack intake worth over a ported 6.1 intake if any?
During a dyno session with a G3 418 we found the 6.1 intake lays down around 5800 rpm. Still makes power, but its pretty flat.
Dyno'd a 436 G3 with a DP intake/750 Holley HP carb and made 668 hp then swapped on a Modman with same carb and lost 80hp at 6400 rpm.
An XV intake made 30hp, 20 ft lbs less than the 6.1 at mid range rpm, but caught up to it at 6000 rpm. Didn't spin the XV any higher and now I wish I had since thats the intake I'm currently using.
I would guess the 6.1 intake would fit somewhere's between the Modman/XV and the DP. Its biggest hold back would be the rpm range.
