A walbro 525 on paper pushes 4-5% more than the 450 presumably at a higher current draw. Need to figure way to add a second 450. Your right, a hpfp won't help.

Are you sure about this?



Not sure what the amp draw is at this testing but that seems really low.

Well the bushings stick out now and the fuel rail isn’t fully seated against the plastic part of the manifold.

that should be great for when 30psi hits the manifold, pushes out the injectors and rail and lights your car on fire haha

everyone do yourself a favor and get some time-serts, do it right.

If time-serts are an option I wonder why doesn't PR include them as part of the install?
I'll probably check the sizes for them when I get home and order some maybe, I can put them in later

How do you know lol, well if it does fail it will fail with me because that's just the kind of luck I have always had

Those inserts he provides are designed not to ''spin'' when they should be designed to not push /pull back out like a one way barb. We made our own after his failed and my rail lifted. Wasn't a install error either. ;)

I don't, a friend made them on the lath while I was pulling my trashed manifold. :mad:

lol So he made them. Sorry bro... just keep an eye and me mindful.
I'll probably heat them back up and sink them a little further in lol and look into those time-serts.....hela coils

Did you have to use a new intake manifold?
