It made mine run richer.. A Lot richer. hence slightly more fuel consumption and lots of pops and bangs from the exhaust.

One quick question.... Anyone..

I heard Matt's 268rwkw RB25 R32 idling and I noticed that the fuel pump was a little noisy (what mine sounds like on a hot day) BUT.. My fuel pump only operates when you touch the accelerator not when idling.

Mine is setup so that it runs Inline as it is an external pump.

Is that a normal type setup? When you touch the accelerator it activates the bigger pump?

yeah, i would also like to know how loud the 044 pumps are, are they really that annoying? like say compared to the annoyingness some ppl find of loud exhausts on the freeway.... i.e. not the same loudness, but would it be that annoying daily driving?

edit: also if possible, could you give a description of what it sounds like? maybe even a wav or mp3 file would be nice :D

Hmm shit...

alright...because ive been getting round 230k per tank since having it put in...though i also had the timing put down at the same time due to pinging (thought the old pump was on the way out), so i thought that was the main cause of power loss...

So, can we adjust the pressure without a regulator?

I was looking to get 1 of those r32 chips in the 'for sale' section, which is ment to have new fuel maps...will this also help?

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
