Hello

There is a 255lph walbro pump in my S2000 supplied with the ILP kit. I am happy with the kit but probably Chris at ILP had no experience with E85 as fuel when i ordered it.
He did recommend me the 675cc siemens deka injectors (as I understand the biggest you can drive without extra driver).

Thing is that I am thinking of upgrading the injectors to allow my tune to make use of the nice power I could get if the injectors could support it. Questions is: can the walbro 255 handle?

If I did understand it right the 255 flows 255 liters per minute. Which is 4250 cubic cnetimeters per minute. Thats the "cc" right?
If this is the case, the injectors would be drinking only 2700cc (4x675)?

Do I miss something completely here or did I get it completely wrong?
Did find some info about it supporting 450whp+ on fuel but what are the injectors in that case?

Happy for directions.
Would a bosch 044 fit in the stock s2000 fuelpump compartment?

 

i have 1000cc injectors and a aem injector driver along with my walbro 255. I use VP C16 race fuel and have no problems.

When I build the motor ill do a walbro 255 feeding a bosch 044

 

you can get rc 750cc injectors that dont require a box, the walbro should have no trouble with e85 and your power goals

 

my tuner Tony at T1 has the new bosch 1000c injectors that don't require additional drivers.


I think the 044 pump will fit in stock location but it will require some modification. I am running walbro 255 in tank now, and it feeds the bosch 044 near the fuel rail, this setup supports my rc 1600cc injectors supports 620 whp on e85 with no issues.

 

he showed me the injectors when i was there last time. very nice!

 

That is some serious flow, 620whp with E85

Anyway the 1000cc should be enough for my intentions.
Thanks for all answers.

 

the 255 by its self wont hold pressure once you get into the 400s on e85

 

Yes I was expecting that, some sort of change has to be done. Wonder what would be the easiest solution...
