Hey all, just a quick Q about the siemens dekas (60lbs)

I have these installed already, but I'm wondering how much power you can squeeze out of them?

I would like to know when I would expect to upgrade them and what sort of power and application requires a fuel regulator.

Thanks

Pat

I'be been told 450rwkw

so are you still using them Billsta? or have you moved up to something bigger? also, what would be the next step?

600odd cc's should flow enough for 450 easy... as long as there's enough presure behind them

Yep still using them,

next step no idea.

Just thought I would mine this thread, never really got an answer on the fuel pressure reg.

So when would you guys thing a reg is necessary?

If your not getting the required rail pressure they can be beneficial, as you might have a big enough volume/flow but its not holding in the rail.

In the old days we used to use rising rate reg's instead of bigger injectors to bump up the fuel pressure and get more flow from stock injectors... but that was early 90s lol

660 rwkw was made with these on a wog tune

200% duty cycles!!

OK, so with the right injectors and fuel pump a fuel reg won't be necessary?
