Hey guys,

Recently at a car show my car lost power whilst going down the quatermile so I turned it off and rolled to the end... Turned the car over and it seemed to run ( only going 10kph) but felt like it was missing... Looked back and the car is pissing out black smoke. So i did a compression test and got 120-120-120-100-110-100 So not good..Also poured a small amount of oil in each after and all my readings went up around 150 indcaiting a large loss of compression probably my rings. So a rebuild is on the cards which is no problem but when i took it around the block afterwards to see if she'd run as soon as it got around 3000rpm it stalled ... then started back up and around the same rev range it stalled again... I can put my foot down and the engine almost seems to run normal then 3000ish and it just dies.

Is this normal?

Also im runnning a power fc and profec B.

All injectors,turbos,fuel pump,afms,coilpacks have less than 800k's on them.

Cheers.

yeah i'd start with checking the cooler piping, etc. sounds very much like a leak somewhere. black smoke is usually caused by major overfueling, which is what happens when a cooler pipe pops off, etc.

also check your afm readings on the pfc. may be that 1 of them has died, or the plug is faulty

    • 12+ months passed so they have no obligation to do a warranty claim. It leaked from the rear circuit. Front circuit was fine, but I tried many times to bench-bleed and in-car bleed (wasted 1L of Penrite racing brake fluid) to no avail. Threw my old BM50 or whatever the standard R32 GT-R BMC is, brakes went back to normal. So from my very limited anecdotal experience, I cannot recommend HFM, even though a lot of their products looks good. Just my experience (I have a genuine Nissan BM57 in a box waiting to be installed now).
    • How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.
    • 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/
