Bypass fuel pressure regulator systems

His opinion is if you already have it, use it. Otherwise it's not worth the time/money to purchase and install.

it obvious that 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.

Still waiting for somebody that claims via pm to the OP that they have improved their car's performance on the track by just adding this bypass to their regulator, to please enlighten me how a pair of -3 hoses plumbed into a regulator makes additional HP, enough HP to run quicker and faster as evident on the time slip because without it, there is NO quicker 60 foots and ET regardless of what John tells him or you, those without the conviction to post publicly and engage in reasonable dialog stating your OPINION based on your belief and JUSTIFICATION for choosing to spend your $ on a regulator bypass.

Dude, you don't get it all. We class racers spen all kinds of money on stuff just for the hell of it. If you are expecting logic, go to the Harvard College website.

(Tongue in cheek). 😄

A REBUTTAL TO COMMENTS MADE BY MR 1320 ____As with many other aspects of each racers unique combination "some" will/might see an increase in performance, some may not and even some may see a decrease in performance by trying many "perceived" performance modifications to their existing setups !!! Strange how that works isn't it?? Anyway getting a consensus from the general racing community on "does it work" allows an individual to draw his own conclusion to the merits of whether or not to make a modification based primarily on others experiences. Vehemently blasting somebody's opinion because it does not go along with your own experience concerning the subject being discussed makes the person making the statement look in my opinion "asinine". Being almost forcefully over opinionated is not a good trait. The man asked what others experienced you offered the results of your experience and it runs counter to what some others saw. Let him draw his own conclusions. If it does not work for him do not call the guy an A -hole. He wants to try an experiment. He is merely asking the "pros and cons" of doing it. Now he can move on to the next experiment and see if that has positive results in the event this one does not produce the desired results. . You will not know what does/doesn't work unless you try.-- Personally in " my combination I feel that using a bypass had no negative effects !!!!!!! did it have any positive effects ? possibly but maybe a HUNDREDTH at the most if that, did I slow down? NO!!!!!! Was it worth the time/money and effort ??? Definitely!!!! So I guess you could call me an A-hole because I tried something that went against the grain in your opinion, correct???-- FED 387

Jim and Mr. FED state my feelings on the subject better than I apparently have. Class racers try things; it is our nature, and the primary reason Stock and Super Stock cars keep going faster. There isn't an experienced racer in Stock and Super Stock that hasn't tried at least 10 ideas that simply didn't work. As many have said, some of these "silver bullets" have actually slowed their car down, which led to going back to the original configuration. And many times, things that don't work alone work wonderfully when another "ingredient" is added to the mix. That's what I call the "Combination Effect". Like Mr. FED said, what doesn't show anything in one combination can show a meaningful improvement in another. To find out, you try.

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.

Wanna compare dick lengths, do we? My car, also built by Pustelny, has gone 9.50s, with slightly more than half the cubic inches of your current engine. If your "former Super Stock car" ran 10.90s at 3900 pounds, mine should run 9.90s at 1000 pounds less. But wait, it's almost half a second quicker than that! But you know much more about how to make a QuadraJet car fast than I do, right?

mine's bigger and I do!

A 468 that only made 600 horse, maybe you DID need that bypass kit on that turd.Made more power than that with nearly half the cubes, and went 8.80's in an AX chassis car....big deal. You gave your response to the OP and he acknowledged it and actually thanked you. Beginning to see why the racers I've met that say they know you call you "Big head Ed" go figure. I'm amazed that you think your car having a faster E.T. means a damn thing to anyone but you, hows it fair to say a twin turbo small block on a 10 inch tire,,,, I can tell you. Not Good. Come join the ranks of lbs. per horse power, or lbs. per cubic inch and then tell us how fast your stuff is!

[1320racer]

your last three replies to this thread have been to me, not the op! Newsflash, this ain't my thread, answer his question or move on!

That said, I know what I know and what I know is my stuff is both quicker and faster than the OP's, yours and 99% of those that post here and somehow I do it without a pair of -3 hoses and a y block!

Oh and your claim that you met racers that "know" me and call me "Big head Ed" well if true, they obviously ain't friends and clearly jealous of my knowledge and my car's performance like you!

As far as "joining the ranks" I assume you mean the NHRA s***t show where you pay a premium for the privilege to race, yet are treated like red headed step children, forced to park in the weeds and the mud, be ready at a moments notice to race on a track/in conditions not safe and far worse than the typical test/tune day at your local track and best of all, race for purses/$ from the 1970s and we don't have enough bandwidth to go into all those racers who are cheating with illegal engines, body panels, etc. you know, the topics regularly discussed and debated for pages right here. Yet all some of you care about is seeing to it that DEEP staging stays illegal/not allowed. What a joke!

So those are the ranks you speak of? NO thanks, I'll pass as has most of my friends and competitors over the last 25 years!

Sooooooooo back to the topic... I'm still Still waiting for somebody that claims via pm to the OP, that they have improved their car's performance on the track by just adding this bypass to their regulator, to please enlighten me how a pair of -3 hoses plumbed into a regulator makes additional HP, enough HP to run quicker and faster as evident on the time slip because without it, there is NO quicker 60 foots and ET regardless of what John tells him or you, those without the conviction to post publicly and engage in reasonable dialog stating your OPINION based on your belief and JUSTIFICATION for choosing to spend your $ on a regulator bypass.

Mr. Ed, first I did give an answer to his question, as did you. I think everyone has "moved on" despite the fact that you cannot because the majority doesn't agree with you. Second, never said those racers were your freinds..to be honest didn't see why they would admit to knowing you. Third I'm not in the least jealous of you, your car, or your so called knowledge. News flash, having an 8 second car with a HUGE engine in it these days is more common than a cold...so easy even you can do it. BTW making 1.** horse per cube is childs play so keep playin.....
