Default Thought i had destroyed it....

I just ran with a 10sec Civic today....

Close battle to say the least.... then it fell on it's face...

Anyone want to guess what all happened...

Inaccurate/Faulty ISSPRO was pegged at 80psi...

Blew the O-ring in the Super 40, and at the same time lost a boot...

replaced the boot, and now it sounds like a cow "MOOOOOO!" and won't get past 30psi...

so i'm going to be replacing that O-ring and then plan on taking that Honda for a walk...

It's a old set of EV2s i have, seems the drive-pressure gauge will never go above 1/3 of what the boost gauge reads, wich seems odd

I'm thinking it's about 10psi off at least, when the truck is shut off it reads about 8ish psi...

That does seem odd. My fuel pressure gauge has me scratching my head sometimes as well, although I'm hoping an electric LP will... normalize things.

if it's "fluctating" then i think that's normal for a mechanical gauge with the stock lp..

It's an electric gauge. It fluctuates, but not like I watch the needle move. Or, not much anyway. It's more like the average fluctuates. A lot. Like I'll drive all day, and for hours it will be running at like, 30psi. Then for an hour or so it'll run at 20psi. Then it's running at 30psi again. Well, allegedly. I'm not too sure I trust it. It also takes a long time to build up pressure when I start it. Really creeps up to idle pressure, takes a good thirty seconds at least. It bothers me.

I'm hoping you dont mean an O ring between the housing and the center section... as I don't have one of those in mine... =\
