I found the deal of all deals. Anthony from lxforums.com sold me his PPP ported manifold for $600 shipped, no core charge!!! What a guy and what a deal!! I received it today and had it installed within three hours, one of which was spent running to Napa for a fuel line disconnect tool and scraper. Anyway, here's some photo's of the PPP ported intake:
No recent dyno, but I ran at the dragsrip the previous week. I'll post my before-after results as soon as I'm able to get back to the track. The manifold flows so much extra air that the Jeep is running lean at part-to-medium throttle and pinging severely! The adaptives will adjust for this in time, so I have to drive is conservatively until it stops pinging. At this point I will be able to perform some WOT runs and adjust the A/F using my wideband and Predator.
