The low pressure 190s tend to internally by-pass at or near 60 psi. Some a little more, some a little less. So boosted apps, apps using an FMU or really large injectors (where fuel pressure builds in the line before even getting the rails), they can be unpredictable.
If I ever do run boost I would want a bigger pump anyways just to be safe so we're good!
What exactly is it about the low pressure 190's that's bad for boost?
EDIT: typed it out a little too late lol
Ohh so basically lets say if you have a 190 that normally would push a 24 lb injector properly at 39 PSI, and you try to push a 42 at like 60 PSI the pump could internally bypass and then cause problems. Is that what you're saying or is my thought process completely wrong? Lol
If I ever do boost my car, I would definitely stray away from FMU's and doing high fuel pressure's at the regulator lol.I've not heard about problems on N/A cars unless it was from someone who added something like a Vortech kit or something. That's the ONE pump that's pretty common that causes things to go "BOOM".
We jacked OP's thread. Sorry OP
90!? Omfg duty cycle on 19's with 90 PSI had to be like 100%I don't think so. He needs to know too. There was an article about it in one of the Mustang Mags a few years ago. I discovered initially, the hard way. I'm glad I decides to check it. I was told that my little 19lb injectors might see 90 psi. So I started the car and closed off the return to see if the pump would even handle it. It didn't.Could have been ugly.

Probably... definitely not the ideal setup.
