Evo X upgrades

ID's aren't magically different than different brands when it comes to flowing more at high pressure. Your DW's will do the same. Also, I'm under the impression that there are different types of walbro pumps, specifically a low and high pressure version. Or go with a fancy anodized pump from another manufacturer that can actually work at higher pressures.

VW guys have been putting 4 and 5 bar fpr's on their stock injectors for a long time. Maybe floppyhead could expand on his trite statement by showing a chart or something of fuel flow over psi for a regular walbro? Maybe?

Also, with all you've done, I am actually surprised you don't have a bcfpr. 20 pages and no aftermarket fpr? For shame! It's one of the first things I bought.

I must admit, the racing fuel setups are pretty bling. Gates' surge tank looks like an octopus in his trunk...pretty cool.

I actually do own one but I haven't bought all the hoses and fittings to install it. It shouldn't be necessary with this turbo from a flow perspective.

This isn't a regular Walbro but the principle should be the same. You'd want a beefy pump setup if you were doing something extreme like doubling the base.

They are different! Some injector will actually start flowing less at higher base pressure.

You need some crazy fuel pump setup to run a high base pressure with high boost on top of it. You would only be able to run super high base's with an all-motor car or with mechanical fuel pumps. Walbros also don't like much over 75-80psi, so 60psi + 30psi of boost = past the crack pressure.

Most people don't need an AFPR, it's one of the most over hyped and often un-needed parts that people waste their money on instead of actual parts they need.
