Max Power Of A Bosch 044?

[yogibear]

what would be the max power of a single bosch 044 with E85 and with 98?

yes i know injectors will be factor but just talking about the pump

thanks

on E85 about 300hp at the wheels - tops

on 98 about 500hp at the wheels - tops

[yogibear]

many ppl made the 500rwhp on a single 044?

would love to get near the 370rwkw

thanks

Yeah have had a few make that much on a single 044. The fuel pump isn't the only piece in the puzzle though. Make sure you go slightly overkill on the injectors and make sure the tuner knows what he's doing. I recommend EFI Performance for tuning. Sean there is a tuning god second to none

Just curious.... I've got an 040 with S15 injectors in my RB25. What am i looking at for 98 fuel?

hmmm... i have a nismo intank pump in my car at the moment and i'm making 285rwkw pulp and 325rwkw on e85...

injuectors are nismo 555cc

i have an 044 and surge tank setup in my ke70 that i'm stripping and was thinking of moving it to the 33... would this flow enough?

Lots of factors, the lower pressure the pump is pushing against the more it can flow. Bosch and other fuel pump manufacturers have charts of this. Ways to lower fuel pressure, ensure your injectors are large enough so the fuel pressure doesnt need to be raised, run lower boost pressure etc

The nismo pump flows more than the 044. Not sure. The only way to know for sure is to calculate the fuel usage by knowing how many ms your injectors are open for at their peak value in the tune you have. So basically if you can tell me what the largest ms value is in your tune, then I can tell you how many L/min of fuel you are using.

Your engine will consume more E85 than it will 98 so the pump will have to flow nearly double to achieve the same power.

Why double? I thought E85 only used between 20-30% more fuel than 98?

i really wanted first hand opinions not hear say.

seems like theirs a lot of hear say in here

I hear what you're saying...

Im running a Tomei on e85, 300awkw with an auto... They definitely seem to flow well for their size.

044 is a massive pump, I thought they would do better than that.

As has been said in many of the posts there are a lot of different factors.

If you want first hand opinions get off your butt and go read the dyno threads for 30+ pages of 'first hand opinions' at least 50% of which will have the 044 fuel pump.

We build these cars day in and day out. Some make more than others, some where the customer supplies shit injectors or whatever. Every car is different. You are only EVER going to get estimation when it comes to this sort of stuff. If you plan on making more than 450hp at the wheels on 98, consider a better fuel pump like the Pierburg which flows 6.5L/min

Hi Yogi

I'm making 530 rwhp with 044 pump and 700cc injectors and 18psi, motec M600. If I want more I will need to upgrade both injectors and pump.

Assuming 98 fuel?
