DW400 fuel pump running a JMS Boost a Pump?

[Kona 18]

They have this now and still sell the old ones ? Do you have the part number? Do you know when they started offering this? Mine was put in about 6 weeks ago...

This is as for last week, If you installed yours 6 weeks ago then you got one of the ones that do not have a check valve. Part # is the same, you vendor of choice will be the one that makes sure DW sends out one with a check valve.

I ran a DW400 and a Vortech BAP on my Procharged car. 9.68 at 145 on e85. Zero issue but I wouldn’t push it any farther than that.

wow those are really good stats... how does the car drive at low RPM's … meaning normal daily driving...

Non at all. Rob Shoemaker at PBD did the tune.

When using the dw400 pump do you need to upgrade fuel lines? what is everyone else doing?

No line upgrade required. There is a slight modification to the pump basket to fit the larger pump but that’s it.

Would just running a dw400 be equivalent to stock pump with bap

DW400 is rated for more... so it really depends what your goals are... the factory with a bap seems more reliable ...

What year is your mustang? Was just curious if works just as well on 15-17 vs. 18+. Thanks!

I'm not at Toy Cobra's power level but I am probably a little over 700 rwhp on a 15 running a DW400 with BAP and duty cycle on pump looks fine in logs.

Mine is a 2018.
I ran 9.69 @ 143 mph with this set up but have since went to a Fore setup for increased boost.

Thats cool. Mine is a 16. Probably around 11-12 psi with 93/Boostane. May try the DW400 and E85 to target 700ish as well. Thanks!

Funny, Lund wont tune a DW400 and BOP setup on E85 boosted stuff anymore......

I totally get it and they don’t want to risk it even though it may be doable to a point but maybe not with a ton of cushion. I tune my own car so if I screw it up I’ll try not to bash myself on a public forum
