Old thread resurrection...has anyone used the Walbro 400 units?

 

I bought one already in the stock hanger but it ended up being the return system and wouldn't fit my MY07. If you want/need it let me know.

 

Yes I have one in my car. I am about to swap it for two 340 pumps though. Mine started dropping fuel pressure at 515whp on stock lines running e85. I'm sure with bigger lines it could do more.

 

Thanks for the replies.

liquidgsr you have email

 

Been looking at my fuel setup and seems like the full blown complete fuel system is the best bang for buck shooting for 550whp on e85. I dont want any restrictions and as little problems as possible.

you guys think the standard pumps that come with the dual setup is sufficient enough?\

forgot to mention i currently have id1000's but have read id2200 would be a better choice so i will more than likely upgrade to those

not shooting for 700hp or something.......

any other possibilities besides this setup?

thanks

 

You will need to up the base pressure on id1000s. For 550 two inline pumps will be sufficient with those. I have made close to 600 on a few cars with this setup and e85.

 

One aeromotive 340 pump 560whp all day no issues stock everything including stock fuel pressure. You don't need dual pumps. Ask LJ at Fullblown he will tell you. Anything over 600whp I would consider duals

 

Thanks a ton guys
