It's supossed to supply enough fuel for 8psi with thier fuel pump. Should be good for 6psi. You'd probably want to put a fuel gauge on the line and see what it is capable of. Unless you can find out the ratio. But for some reason Supercharger guys seem to know little to nothing about fueling.

:rofl:

bonus points for being the first guy to use bullets on the forum :bowdown:

I've gotten used to reading posts like this:

Inline? BOSCH Holley Edlebrock Walbro In-tank? Edlebrock Jackson Racing Walbro 190 190HP Will the 94 - 97 kit sold HERE Work for me or not? 255 255HP SO MANY CHOICES WHAT WOULD BE MY BEST BET? 1990 Greddy Base kit with ETD crossover/turbosmart VTA BOV (6psi for now......not planning on going above 10 - 12) THANKS

The jrsc fpr is a 12-1 just like the one supplied with your greddy kit. why would you want what you already have.

why thank you, lol......but am i really the FIRST?

even if you have the 190 or 255 walbro pump, does that mean it pumps at a constant level? or can you control it by using a management system?

simon

the pumps go at a designated rate in regard to there mechanical efficinecys look at the charts and this site to see how and why.

Please do some reading and searching on this board and Miataforum.com on why a 255lph pump is incredibly overkill and has the chance of overpowering your stock FPR, making you run overly rich when out of boost. 190lph HP is the pump you want.

He must hang out with the supercharger crowd, who fuel miatas based on hearing knock or not.

Yeah dude, why even bother reading this post if you end up with a 255 anyways?

yeah I know wtf.

hey, whatever helps you sleep at night :gay:

Maybe he needs visual aids:

Look at the graphs carefully. You'll note that the 190lph actually has a better fuel flow at high pressures. Also note that at lower pressures the 255lph delivers a lot more fuel and thusly the overpowering effect.
