Did a little search and couldn't find much info. Just wondering what the power limits are of a stock fuel line in EG's. Trying to get a base as to what I should do with my fuel system as the season nears closer. Any info will help, links, comments, whatever you can give me to lead me to a direction as to what I should be using to reach the power numbers I'd like to make this year. Thanks!

I have personally made ~575 whp on stock lines with just a walboro 255 pump. I think others have gone a bit higher but I'd say the safe limit is around 575-600 and thats more due to the pump than the fuel lines.

540 on stock lines to the filter, and braided from the filter to the rail. stock return.

not a limit but the guy made power on stock lines https://honda-tech.com/forums/forced-induction-16/broke-into-640whp-stock-head-stock-fuel-lines-fpr-itr-cams%3D50-whp-1960338/

***remember fuel line sizing is tied to injector duty cycle***

550 WHP is a common limit.. I made 560 WHP on stock lines, and that was it. After upgraded lines, I had to drop injector duty by 20% which indicated maxed out stock lines.

People have made well over 600 on stock lines, that's a fact.

People have also made 400 hp on stock GSR motors. Does that make it a good idea? Does that make it reliable? For TTT to see a 20% reduction in duty when switching out lines says a LOT. Stock lines aren't meant for 550+ ... You might be able to do it, but you're putting unnecessary stress on your fuel pump by making it pump that much fuel through a tiny straw.

You are correct but he asked for the power 'limit'

I guess I made a quick response with out much thought

BubsBoostedEG

ive have made 750whp on stock lines feed and return with a 255intank and a 255 inline on gas 500whp om e98

blundar

that's nuts I'm amazed.

If you do an inline pump between the stock filter and the rail then you can make a lot on stock lines.

Will a walbro inline be fine for 550 on e85 when combined with a intank? or just stick with a bosch 044?

aznkr4zyboi

what about on stock fuel pump?

The Walbro will be at peak or close, better to use a Walbro intank to a Bosch Inline.

No.

You think it has to be a bosch inline fuel pump or you think it can be a one of them cheaper airtex pumps ?

I've seen mid-500 whps with stock everything and Walboro 255lph. Seems like that's the typical concensus going around that's not too stressful to everything without an inline.
