Absolutely no change, no improvement whatsoever.

Mike, call John Rademacher @ Product Engineering, he can explain it better than me.

My fuel system is all John's aka Product Engineering. Again absolutely NO change, no improvement, no difference. Save your $.

Thanks to everyone for their responses. Based on 1320racer's comments and photograph, I have to ask if you had a fuel pressure-based problem when you decided to put the bypass kit on? It looks from the picture that you're using -8 line into the regulator and either -6 or -8 out. Does the car use a QuadraJet, or a 4GC? I guess the key question is, were you hoping to cure a problem and the bypass didn't help (i.e. you still have the problem), were OK but put the bypass system on to guarantee you wouldn't ever have a problem, or put the bypass system on because you were assured that it would pick the car up? Thanks in advance for your answer.

1320 racer is an expert, even though he doesn't race a super stock car.

Actually I do.

My car is a former super stocker built by the best, MPR, that now has a 900+HP BBC bracket engine under the hood that accelerates it well into the 8's and it's a safe bet I've made more passes down a 1/4 mile than most class racers over the past 25 years.

Back to the OP's question... -8 in and -8 out feeding a Holley 850. Just had the bypass kit laying around for years so I finally decided to put it on.

Key word is..."former super stocker" ,but you are not a class racer, as usual, your opinion is irrelevent.
