Well I have a dyno sheet showing 426/509 and the fuel pump was in the 8X% efficiency range says the SCT pro software. I made sure he kept his eye on the pump. Maybe I don't have a Focus pump.

RE: Focus pump? Check this out.
What was your fuel pressure at? My Aviator dropped to 25psi at 421rwhp and starts leaning out. I'm about to install a boost-a-pump this weekend to fix that little issue. 426rwhp is not out of the question for a single Focus, thats right at the limit of what they will usually push. But the difference between 426 and 500 is pretty big when your talking about fuel.
By the look of the description and part number, that doesn't sound like an SVT Focus pump though.

the dfference is blowers the least efficient of all power adders.. because power is wasted spinning the blower.... if a focus pump is doing 425 with a blower it makes sense that it would support more on motor with spray..... my car with the 125 shot keeps everything together with just a focus pump and im making enough power to trap 120 boucing off the limiter 1st gear 2nd gear.. then going strait to 4th....

I've datalogged the fuel pressure before, and I'm thinking it was in the 40's? I have a FPSS, so that's not a concern.
I guess it's not a focus.

I understand 426 is different. That was on the 100 shot. Now I'm on the 200 shot. I got a buddy to video the wideband the first time out with the 200 and it never got above 10.9. That was with low bottle pressure, just to make sure the fuel was there. It runs in the mid 11's with good bottle pressure.

And Bobsls, that does make sense about the difference in blowers to nitrous. I wasn't really figuringin parasitic loss, in that case it would make sense that the actual rwhp limit would be higher for the same pump on a nitrous setup.
