I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

Hi Guys,

Is it better to run vacuum off the compressor housing to the boost controller or block that off and run it from the stock location in R33s (intercooler pipe?)

My ATR45SAT has it on the compressor housing and a friend with a similar turbo just blocked off his compressor housing one and ran as per above.

Thanks!

Thanks Dan, I read something similar just wanted to double check.

Another question - Does anyone know what size the studs are on the Hypergear ATR45 turbo dump side - I understand that most are actually bolts but there are two studs also.

I'm interested in how much to upgrade SS2 will cost, The new one sounds unreal and mine is due for a retune with E85 and new injectors when I can get all the parts together and on the car so the thought of upgrading turbo sounds good to me :)

Haha.

Honestly, mine is probably about perfect for driving around town, which is pretty much all it does.

But now that we have E85 on pump, i know im going to make more power so may as well make a bit more on top of that :)

I just want a little less lag as I track the car quite a bit at Wakefield (which is what I mainly use it for, does see the odd trip to the gym).

I find with the SS2 I need to drop it down to 2nd around certain bends, then bam I have too much torque/power and it's dori & smoke LOL.

However it's tits on the straight at Wakefield, I over take cars like no tomorrow haha.. here's a good clip of just that:

Hey Stao, when you get back just so you don't miss my question but will the SS1PU be more snappy and responsive than the SS2?

Plus more responsive than say the OP6?

yes that should be, and more responsive then a op6 high flow. but will be maxing towards 270rwkws mark.

      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?

      Leak from Tokico BM50 Brake Master Cylinder

      By GTSBoy · Posted

      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/
