so why ask if you're going to try it regardless of who says what? Answer...no matter how many tell you that all you'll see is a lighter wallet, the only opinions you are interested in hearing are those that agree with what you had already decided to do.
What do I know, my former Super Stock GT Firebird is quicker and faster than 99% that post here, has run a best of 8.72 @ 154 and 1.17 60 foot with a fuel system plumbed by Mike Pustelny using all Product Engineering components and NO bypass kit and my dragster has run a best of 7.18 @ 186 MPH without a bypass kit plumbed into it's regulator. Just imagine how much quicker/faster it would run with it.
I try things too, have for over 25 years, what I don't do is ask opinions on internet forums of what I have decided to do with my car, my $ and my time.
FYI, for those that missed it a previous post here, I have also run a Q-Jet for many years back in the 90s, atop my 600+HP at the time, 468 BBC, running as quick as high 10's with it in my 3900 lb. Chevelle. No PE pump, regulator or bypass. Ran a Malllory Comp 140 pump, filter and dead headed regulator and no issues what so ever.
