318willrun said That mod helps the upper end. The kegger intake was designed for 1500-4500 rpm's. If Jaws isn't going to race it, he won't benefit much from that. I did two things to help part throttle low end on my '01 Ram. I advanced the timing by slotting the crank sensor, about 3 degrees I ported and polished the throttle body from a 47 mm to a 50 mm. Part throttle response is more crisp. Bottom end will melt the tire.... remember this? LOL Click to expand...
