I currently have a pair of Walbros (don't recall which model to be honest) and I think they're at the end of their life.  I need to replace them.  Should I go with 485 or the Hellcat models?

Personally the helcats seem better as they are E85 specific and not universal as the other are

Some tuners advice against using new 525 warlbros in the factory fuel boat, at least not as a primary. The reason given is notably higher current draw and heat dissipation for relatively trivial output increase (something like 10% at GTR operating pressure levels). It was said factory in-tank wiring and harnesses have trouble coping with increased power demand. The recommendation is to run high-pressure “274” model of normal 485 warlbro.

My tuner advised the same when I asked him about these new pumps. I even have large gauge direct wiring straight to the pumps and he still advised against them due to heat concerns.

I heard that too but when I spoke to my tuner (Bill @ SiR) he said otherwise.  Regardless, I'm getting the injectors cleaned today and going to see how a data log looks after that.  If I need to replace pumps then I'll have to do some more homework.

 

How are the AEM pumps?

I run the 485 primary and 525 as secondary.  I didn't want to run two 525s because of the current draw and this was the next best thing.

You dont need 485's for FBO. They will work fine but flow way over what's needed. If you are sticking with FBO there is no need to upgrade.

Thanks good to know!  So far (knocks on wood) since injector cleaning car has been driving fine.

+ 1 485s are good for over 1000hp. I ran asnus and never had an issue.

Why not a single Bugatti pump from AMS? No heat and quiet as hell.
