No worries, still keen to see what you can come up with for the little motor, BTW that R32GTS-t I offered you has since been sold.

Further developments. This is a Ceramic ball bearing ATR43G3SAT turbo that no longer require water cooling. Video shown turbo shaft rotation on RB25det Neo motor with engine start and shut. Super responsive.

Does that mean that you will need to idle down the car like an old truck after each drive?

Water and oil cooling has many benefits, unless the CBB is different

Just works like a normal water cooled bb unit. Except it doesnt require water cooling. Made for cars with oil cooled only turbo setups.

I will withdrawn the comment for now. It could be other causes, The bov is blowing air out, not sucking in.

You can run water to it if you want to.

Previous data shown boost curve is almost identical. but this one made more power.

Using same car with identical mods:

21U G3 high flow:

    • 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.
