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

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 :(

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

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info

      It looks like you've got Ikeya control arms and an aftermarket sway bar, maybe whiteline?  Or am I just going crazy? lol Unfortunately it won't, but what it will do is look really pretty. That's about all unfortunately.  How much neg camber do you currently have? Generally lowing the car dials in quite a bit of neg camber as it is. If you do go down this path, your best bet is get adjustable arms, toe arms (or preferably a good HICAS elimination kit) and traction rods. With all 3 being adjustable, you'll be able to dial out any bump steer that is introduced by playing with the camber settings.
