This step voltage booster is designed to up the voltage to a fuel pump to increase it's output. It references boost so the fuel pump will only get the added voltage and added output when needed. These have been proven in the Mustang world.

I just ordered a Red today so I am thinking of ways to get more fuel pressure to go with my new Lucas "secret sauce" 1260cc injectors . So far the injectors idle as good as stock(better than my FIC and RC) and trims are getting dialed in to around +/- 3% The injectors are advertised as methanol safe and they are disc type instead of ball and seat. The other cool thing is they have 3 large guides for the exit and around 6 holes on the disc. The three large holes are around 120 degrees apart for good fuel seperation/dispersion in the chamber I imagine.

I dremeled and machined these injectors to be similar to the Delphi/Denso bodies so fit the stock fuel rail

I contacted my source and asked them if they could machine/manufacture Denso/Mitsu style and they will get back to me

At the bottom of the first link in post there are links regarding test data and flow tests using their test equipment cool stuff.

Here is another link albeit older about fuel pumps also. i was considering the Supra Denso pump but it is advertised as 280-290 lph but only flows slightly more than the Walbro.

I don't want to spend the money on diual pumps in tank and in line is not for me

Thoughts......

 

Any more info on these injectors? I'm looking for something in the 1400-1600 territory for my DSM.

 

The injectors are only 1260cc or 120lb. They are made by Lucas and my supplier will not tell me who he gets them from. He does say they are designed with alternative fuel in mind i.e. methanol which is more corrosive than ethanol. I turned down my idle to stock levels today and still trying to nail trims down although they are below 5%. They come in a Ford/GM configuration so I had to modify them a bit to make them fit the EVO fuel rail. I also had to make the inner diameter of some viton seals larger to fit the new injectors. Supposedly the supplier is going to contact his source and ask about making DSM specific or Denso style injectors. The Delphis we commonly get are machined at the top if you look closely you wil lsee where the plastic has been ground/machined off. I wish I could say more but it's all I really know. Knowing the mods. It was a minor pain to get these to work in a Evo but so far it has been worth it.


PS I heard the Bosch 1600's were designed for Propane or non liquid fuel. I also heard that Bosch stopped making them. for what it's worth

 

Do you mean to say that the 1600's sold by some vendors are Bosch units not intended for liquid fuel?

 

I would also like to know about the BAP. Has anyone tried it?

 

Yes this is what FIC said they were not originally designed with for fuel but rather propane I believe this info. came from FIC

 

If you go to Kenne Bells' website or call them I'm sure they will tell you what it could do. It will raise voltage to say your Walbro 255 and with higher voltage create higher output. They sell 2 models and If I bought it would be the smaller one as I will only have a Red turbo and so far my plans are to run the Walbro to it's max. safety then decide if I need more fuel pump for more power. 450 are the numbers everyone is saying when the fuel starts to go away so.......

My other thought is to 2 parts e85 to one part 91 octane and this will make right around 100 octane. Tune with this just to see what the trade off is of being able to get more fuel but being more knock prone due to lower octane.

A lot of blown Mustangs and GM cars have run BAP for years without problem other than lower life expectancy of pump due to more voltage being run through it. Walbro's are cheap and to have boost controlled fuel pump boost would be cool and an alternative to the dual in tanks.
