Don't rule out the Avenger SuperCharger. It has alot of power as well. 50% more power with 8 pounds of boost.First off, I will admit that I have not read this entire thread yet...got to page 12 and couldn't wait any lnoger to post. I am seriously considering the Ripp or a HEMI. I had no idea about all the other SC available and really have enjoyed this thread.
One thing I either missed, or feel is missing from this discusion is this. It seems as though the main concern and comments are in regards to the Sprintex vs the Ripp and the longevity and dependablility of both and the amount of power they put out at the low end. I am fairly confident that neither (and extremely confident in the RIPP because it has been proven) will leave me stranded in the middle of nowhere because the engine exploded. That being said, I actually feel as though the lack of power increases at the low end by Ripp are a PLUS. I feel as though the weak points of the drive train are going to be anywhere other than the engine when I am out crawling over rocks or chasing after pigges in the Jeep. With this thought process the last thing I need is 50% more power being directed to my axles when I am simply trying to crawl over an obstacle. I have yet to be on a trail and see someone's engine fail, but I have seen numerous drive shafts bust or axles twist and almost every one of them was when someone got a bit to heavy on the throttle.
I agree the Ripp is best on the streets, although it appears to be great on the trails as well (from what I have heard and seen). My number one concern is not breaking down in the middle of nowhere, and for good reason. I was recently in the middle of nowhere and had a hunting accident in which I was shot multiple times (I am not wanting to get into this on this thread) and we had to RACE to meet EMS and a Helicopter about 35 miles from where we were. So again, I don't want to break anything and I feel as though the stock 3.8 put in 4 low has all the power you need below the 2000-2500 RPM range when the RIPP really kicks in. On the highway I never see below 2000-2500 RPM and this is where the 3.8 is severly lacking.
Just my thoughts...FLAME AWAY!!!
edit...I am now going back to read the rest of the thread
