Hey guys

I was trying to set my boost today, and as i was driving it went up to 20 pound for a split second

My cars a rb20 silvertop with r33 turbo

It is now making a loud wooshing noise like air is pushing out, it is still generating boost but stops around 6-7 psi, but i have the rb20 actuator so it should be around 11 or 12

Would my turbo be blown, or just a major vacum leak?

I have checked all the intercooler pipes (but it is night, so i can't see everything), but nothing seems to be wrong

any ideas?

Also idle is very rough and jumps down to about 100 and back up constantly

Thanks for any help

probably not

it would whine n squeal like a bitch and usually make bugger all boost

you may also see oil coming out of the throttle body / intercooler silicon joiners, that usually the oil seal in the turbo shagged

Much appreciated

Hopefully it is only a vacum leak

I will find out tomorrow

Thanks again

    • 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/
