"pops" as in an exhaust sound... or more of a "knock" under the bonnet...

if its the latter - wind the dam bleed valve out and drop your boost before you fk your engine!!! Get your tuner to check out the bleed valve and set it the max boost they think u should safely run.

dude dont attempt boost adjustments without using a dyno!

the popping you hear is your car slowly dieing lol, it's detonating (also known as pinging)

you need to re gap your spark plugs to .8 i think on rb25?

adjusting your boost on the dyno will also reveal what your air fule ratios are like!

i recomend you set it back to stock boost

book your car in to a reputable workshop for a dyno run and boost adjustment.

it may cost around 100 but it will save you thousands if your motor goes BANG!

trust me i found out the hard way

cheers

Adam

    • 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
