So i know they have been out for a while now but i haven't seen too many posts about them whether good or bad. I'm looking for a single pump that can support around 550whp on e85. i looked into running a 044 inline or a double pumper but i wanted to keep the system as simple as possible by using just one pump. it seems like most of the pumps out there that can support that kind of power are usually a hit or miss. Has anyone successfully used this pump and made 500+whp on e85 and not have it fail soon after lol? also if you have any other input on what could work please post it up. thanks in advance

 

Also for the guys running this pump are you running a stock fpr or aftermarket and is the pump hard wired or stock wiring.

 

Bump. Nobody? lol

 

Aftermarket lines filter rail and regulator with a rewire and that pump will make 600+ whp. Add a boost a pump and your good for 700whp.

 

pump is good for 800hp, already did it. safely 750, 835 was leaning AFRs up top.
stock regulator and return. -8AN feed. pump E85 & ID2000.

 

I was thinking of doing the 450 with a -6 feed but no rewire so I don't have to run a aftermarket regulator. Hoping this could handle 525-550whp on e85. Chamelieon did you have yours rewired because I noticed you said your setup was on the stock fpr?

 

i had the 400 pump and had to rewire aswell, so i had to use an aftermarket FPR.

 

USCGSAM what was the reasoning for the rewire? Stock wiring couldn't keep up?

 

base pressure was 65 and was done on AEM EMS, so i doubt with even no wiring you can get the pump to 43 fuel pressure. you want to get the most out of the pump i would recommend giving it direct battery power. for your 550 goal you need a hair more pump than a 255... so a e85 walbro 400 should fit you nicely.

 

the pump wouldnt run with out it...so i assume yeah the stock wiring couldnt hack it.

 

i also had good expirience using the stealth pumps, from aeromotive. the 320/340 pumps would be ideal for your goal http://aeromotiveinc.com/products-page/fuel-pumps/11142-340-stealth-fuel-pump-offset-inlet-inline/

Thanks guys for all the input. Btw detroit pistins I have read all those threads and have been speaking with mrfred through pm's I just wanted to see if there were any other people using it successfully long term and making over 500whp on e85.

 

NP man, good to know you are aware of them!
cheers

 

now this may sound stupid or it might just work but is it possible to run the pump on the stock wiring for idle/part throttle conditions and also have the pump hardwired by tapping into the power feed for the pump. then use a hoobs switch set to about 9-10 psi to activate the relay and feed direct voltage to it. i'm assuming i can tap into the pump power feed also also use that power to the relay coil power feed then use the hobbs to send the ground to activate the relay. best of both worlds and i can use the 450 to its full potential and keep the stock fpr. i was looking into this hobbs switch from racetronix http://www.racetronix.biz/mmWEBSTORE/Images/G7DP.jpg it looks a lot better in quality and cleaner also with the 2 pin metri pack connector. in theory it should work lol but we know how that goes.
