Hey guys, I've been searching on the internet for info on this setup. Now i know the 450 is capable of over 700hp but would adding a fuel pump inline be restricting? I want the best possible fuel flow with a lower duty cycle on the injectors. I was thinking of adding the 044 inline but I'm not too sure if it makes sense to add a pump inline that flows less than the in tank. Turbo is S366 .91 hot side with 1650cc Injectors looking to run at a base pressure. Goals 700 in the future but 600 for now with room for improvement later down the line. (e85)

 

Stock Block And Head BTW

 

The walbro 450 should be fine at 700whp on straight e85 as long as it's wired correctly. I havea walbro 450 and I make over 600whp with it running straight e85 with the fic 1650cc ev14 injectors.

 

600whp. here on a single walbro at stock pressure running id2000s. e85

 

nice! you running a relay as well for max fuel pump voltage?

 

what turbo you running? and duty cycle on injectors? thinking about doing 2000s as well

 

Yes I run a relay. You must run a relay with a 12-14 gauge wire directly from the battery all the way to inside of the fuel pump hanger. I run the sicence of speed fuel pump kit. That's the best kit out there because they give you the pins that you need to repin the stock plug on the fuel pump hanger.

 

The 044 inline, will enable you to bump the base pressure...60+ basically...it'll do nothing for you at stock base pressure.

 

I'm running a Borg s200sx FMW T3 .70AR injectors are at normal duty cycle we never touched fuel pressure still plenty of room with the id2000s. I went with them so I wouldn't have to turn fuel pressure up so I wouldn't work the single pump ad much..pump is wired with a SOS kit..to the battery with relay.

Yea I was looking at that kit and it's a great price deff going to grab that
