I’m not seeing much out there that suggests the Goliath outflows the LPE pump. Perhaps because it’s new and no one is really pushing it yet..? Maybe you’ve seen something I haven’t to suggest otherwise? But I know you and I had this discussion previously and it did not seem like a worthwhile upgrade at the time.
Now if the Goliath really does outperform the LPE (and I hope it does) then maybe the +70’s would make sense. I just hate to drop $3K for no gain.  |
Allegedly, the Goliath will hold more fuel pressure than the LPE up to about 1200-1300 wheel HP with XDI 65's and a 38% fuel lobe.
I can't confirm this as I don't have the experience with the Goliath yet at those power levels. If you could hold 2600 PSI on a 38% fuel lobe with XDI 65's, you would definitely have more headroom.
I have found on the stock cam lobe the Goliath holds pressure better than the LPE but not by more than about 5%. I imagine it would be more with a cam but again, I can't confirm anything. I only see what Katech posted and claimed the goliath would do.
