Fuel Pressure Logs

[Fobio]

awhile back, Big Dad asked about fuel pressure @ idle and we had a few chime in and also stated their fuel pressure @ WOT. with ATR out and tuning in earnest, I'm wondering what your FP's are...

going thru my logs, I noticed that I don't hit 1700psi anymore...I believe @ WOT, I hit high 16xx psi...around 1680...no concern yet, but I'm also considering a fuel pump upgrade.

What are some of your fuel pressures now? idle/cruise/wot?

i haven't logged one yet but i have looked at my dashhawk

idle.....425-435
cruise....approx 1630
WOT ... approx 1680

but i have seen it peak at 1700, but i have no proof cuz i haven't got a log.

Thanks!

The pump internals upgrade is supposed to guarantee operation within the 1600 - 2000 psi range...since we're already operating above 1600psi @ WOT, it makes it hard to justify a fuel pump upgrade eventho it may make sense in the long run...

I'll post up some AP logs soon when I get a chance to test...

yea i should really do a log of it so that i can confirm the numbers...
