ati d1 users, got a ? I'm wondering if any of you guys would happen to know how much boost you're making at different rpms. Like how much at say 3000, 4000, 5000. Break it down as far as you can. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> I imagine this won't be very easy to find out on automatic cars since you don't make a transition though the rpms like manuals do. I got a tuning idea I wanna try for us that don't have a boost referenced afpr yet. However, I don't have the kit yet so I need your info for boost #'s.

Re: ati d1 users, got a ? I have an P-1 ATI (w/7 lbs of boost) that I had run on the dyno a while back. Having LT headers on it reduced the boost numbers by .6 at 6,000 rpms.
2793 rpm = 1.55 lbs of boost
3250 rpm = 2 lbs of boost
3750 rpm = 3 lbs of boost
4600 rpm = 4 lbs of boost
5250 rpm = 5 lbs of boost
5750 rpm = 6 lbs of boost
5904 rpm = 6.4 lbs of boost max
Since then I have added the Stage II heads, and a 224 cam. The Pulley is being changed to give more boost due to losses that the Heads and Cam will have. No new dyno numbers for this setup are available yet.
