Bypass fuel pressure regulator systems

Ed, I think most recognize that you have a great deal of experience in drag racing, and that that experience can be very helpful to others who don't have it and are trying to learn.

I'm nobody's idea of the PC type, and I do appreciate frankness. But, from what I can tell, oftentimes your experience gets overlooked by the messaging, which is a shame.

By the way: How much does that weight box weigh? Nice piece. Mike does build very nice cars.

This is why I seldom post anything on boards. The original question was simple; "Has anyone converted to a bypass system and did it produce any gains?". The initial responders simply answer the question, but soon after, the "experts" show up, to criticize and belittle the questioner. I should be working on finding the right camshaft? Gulius picked the cam when he built the engine. I should understand what a fuel system really needs to work properly. I do. I've been racing for 35 years, and this whole thing started when I noticed the pump was delivering "beer foam" to the carburetor. Believe it or not, there was no perceivable performance deficiency. Investigated, learned that the pump had never been rebuilt and called John to discuss having it inspected and re-sealed. John asked if I had ever considered a bypass system (because the car uses a Q-jet), and went on to tell me how it had helped people like my friend Jason Line, with his Buick stocker. So, one more time; the question was "Has anyone converted to a bypass system and did it produce any gains?" Don't help; just answer the question.

Mike...NO and if you go back to
My first reply I answered your question. It wasn't until another poster attacked my reply that my follow up responses got lengthy. I did not critics or belittle you until you attacked me/ my replies. If you only want opinion and reply from those that agree with what you have already decided to do, I suggest you don't ask for opinion on Internet forums.

Steve, it's not my concern who like or dislikes my replies. What's important to me is I offer honest advice based on my many years and passes without a hidden agenda. Unlike many that post here and elsewhere, I'm not here trying to sell parts and services.

Don't know how much the weight box weighs, never had it out of the car but I'd guess at least 25 lbs.

Your advice is both appreciated and considered. I know what I'm doing, but want to see if John's argument that the bypass system helps Q-jet cars with the fuel supply issue (due to the small fuel bowl) is proven in practice. Everything works in theory.

Ed - Yes, you did answer the question.

Mike, while I believe John builds the best fuel
Pumps available, it's No secret he's a bit of a nut and the reason his latest venture PE Fuel Pumps are not flying off the shelfs like his former company Magnaflow now Magnafuel.

John and I went a few rounds years ago with some of his claims and statements and John would have you put one of his 500GPH fuel pumps and a -10 line feeding it on a 300HP engine if you let hm with a bypass kit too.

My current carb is from Bob Book. He is quite picky about carb and fuel system setup.

When I ordered the carb I asked about the regulator bypass setup. He said if you data log fuel pressure you would certainly see an improved fuel pressure reading. He also stated that on track they never saw any positive gains from the bleed system.

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