I have a 2.0 built motor full bolt ons running a fp black, i have a walbro 450 re wired, FIC 1800cc injectors and FPR. I will be ding stock ECU speed density. my goal was 550AWHP on a mustang dyne some people tell me its definitely do able and others are saying no. according to walbro the fuel pump can support 600AWHP and FIC claims their injectors will support 672WHP on E85 with a 90% duty cycle. i will be running on E85 as well. just wondering what you guys will think get me to 550WHP i was going to order the buschur double pumper but if i can keep my 450 that would be great.
Thanks!

 

Yes you can make that power on E.http://www.tscomptuned.net/portfolio.htm

As you stated, the fuel pump... This will be your limiting factor. I would get the double pumper and call it a day.

 

Definitely invest in a double pumper. What are the specs of the built motor?

 

With -10 feed/return with one walbro 450 rewired with adj FPR we were able to make 680-700WHP dynojet on 5leepers 2.0L car before we ran out of fuel. (E85) (ID2000 injectors)

550 mustang is around 620WHP dynojet. It should be safe to do on a single walbro 450 hard wired honestly. FIC's calculator on the site is very conservative, so take it with a grain of salt.

 

Thanks for the input everyone, im returning my injecotrs to buy the 2150's and be tuned on that along with the walbro single 450. and maybe if the money is right buy the double pumper, im guessing that should definitely put me in the high 500's low 600's on a mustang dyno

 

You're limiting factor is going to be the mustang dyno

I'm trying to break 600's on a single Walbro 450 as well and -6AN lines.

I did the STM hardwire using 4 gauge wire to the trunk, tappering down to the provided wire in that back. Still can't get anything more than 13.9 volts using a multimeter.

Hope it's enough.
