I am looking to build my DelSol to make 700whp with e85. I am switching to the ID2000s however I am trying to finish the rest of the fuel setup. I am currently using a walbro intank stock feed line to a bosch 044 inline pump with 6an hoses.... im looking to switch the walbro to the new full blown 340 intank pump with 6 micron filter and switch the stock feed line and 6an lines at the fuel filter to 8an as well...

http://www.s2ki.com/s2000/topic/8586...ank-fuel-pump/

According to the above link graphs the fb340 pump by it self at 45psi base pressure and 13.5 volts is only rated at 300 bhp LESS compared to dual walbros

I am being told by various sources that this setup will not meet the power goal I am looking for and I have in fact not been able to find proof of this actually done.

Considering we all know the walbros can clearly meet this goal why would the fb340 at the rated 1004bhp "PLUS" the bosch inline pump not exceed the 1300bhp provided on these graphs by the walbros....

just a little math:

if you subtract 15% of 1300bhp to give a wheel horsepower number you get 1105 WHEEL horsepower roughly... which would annotate pump gas capabilities which sounds pretty realistic at like 100% duty cycle

if you subtract the 25% from the 1105WHP i come up with 830WHP to annotate for e85 fuel requirements...

I have seen cars with dual walbros make 800whp with e85 which justifys my awful math skills....

Why cant the FB340 w/ 8an fed bosch inline not break the 700whp plateau with e85? I understand that running the second pump inline is not as efficient as running the intank parallel walbros but why would it not meet or except what i am trying to achieve according to the graphs.

Some will ask why dont u just get the dual walbros and shut up... well i have a del sol for one which is not a direct fit and I would need to also buy 2 walbros because my one in the tank is going bad (6 years old)... so 2 walbros plus a hacked dual pump hanger is over 500 dollars... when i could just spend like 150 bucks (the fb340)and be done because i already have the bosch pump... and regardless i have to change the fuel lines... so i hope that justifys my asking...

Hopefully someone has time to go a little in depth on this subject with more knowledge than I...

If I hardwired both pumps with a relay and pulled more like 14.5 volts instead of the 13.5 volts on that graph wouldnt that make the pumps put out even more fuel delivery?

Im guessing you are trying to steer away from sumping the fuel tank and running dual 044's?

DelSolMarine

lol yes pretty much... this setup would be 100% easier... atleast for me...

Buy the full blown kit put w.e pumps you want ( walbro, aeromotive etc). I bought a used full blown kit with lines and fitting for $450. Its not expensive and you don't have to sump your tank. To answer your question nobody is going to have real world experience with these new pumps+a pump inline. Technically it should work but you never know until you or someone else try's.

Fullblown kit does not fit Del Sols. I have one in my car, but I had to modify everything on it to get it to fit. For some reason Honda decided to make the Sol's tank extremely different.

A local Saab just put down 700whp with the 340 pump and an 044 inline. I know its a different platform, but its still a 2 liter 4 cylinder.

thanks man! im going to give it a try then atleast someone has done it! ill post back in what will probably be july before i get all my parts and finish assembling everything!!! do you what type of dyno that saab was on? dynapack numbers?

dyno-flo single roller.

awesome! thanks bro

what kind of base pressure would be needed to make this setup work? sounds like 45psi is not going to provide enough volume which means if i need more base pressure then the overall delivery of these pumps would be decreasing because i need to increase volume...

Just letting you know. Asking for 700whp out of these pumps, our DW301 included, is a lot.

If you were running an N/A engine @ around 40-50 psi, they could keep up. but when you start with a base pressure around 40 psi and add 25-35 psi boost (or more) you are looking at a total system pressure of at least 65 psi.

Now, if you are really wanting to try and push the pump, you could get a boost-a-pump and try 16-18v. With one DW301 and a set of our beta 1500cc injectors, Modern Automotive put down 630awhp in a 1G DSM on E85. That was with the DW301 hardwired and seeing 13.5-14.0v.

Just keep in mind, the harder you push your fuel system, the shorter it's life expectancy is going to be. So, if you are okay with replacing the pump every 3 years or so...give the single in-tank route a try.

man garage808 said he made over 800 on his a1000 on e85 man im guessing he was on id2k's as well

i have made 650 on my a1000 and rc 1000's on e85 with a 67@26psi not ideal but it did it lol
