We took Daves GTR out for a test and tune day yesterday and ended up with a 9.4 with something like 137mph. The first run the fuse for the injectors popped as he launched (fuse was to small). Second run he knock it into neutral instead of second (thank god for rev limiters). The third run was the 9.4 but a lot of time was spent on the limiter (need to lower the shift lite rpm). Unfortunately it popped the camshaft seal out on that pass and oil ended up everywhere so rather than fixing the seal and cleaning the oil off only to have it run out from under the car somewhere and onto the tyres we called it a day. We were hoping for some more passes to try to get the car where it should be as it has a lot more in it yet.

Yeh Grant spent most of the day working on the arse end trying to tame the beast down off the line. The last pass he did the car launched much flatter and straighter so he was able to keep his foot into it and ran a 8.9. The 120y will definately go into the deep 8's with some more boost and taller gearing.

Any other info on the 120y engine setup ect?

The GTR runs a 26/30 with Nitto I beam rods, Mahle pistons, Supertech valve train with Tomei cams. Has an EMS ecu with M&W cdi and innovate data logger on methanol. It uses a Jatco 4speed auto with a TCE converter. Turbo is a borgwarner rated to 1200hp but we arent pushing it yet. Suspension is hks prodrag and has custom en26 axles. Slicks are 26by10by15.

The 120y has a commodore v6 with mechanical fuel injection and a t04z turbo on around 20psi. Pretty sure he runs a glide. The car was built to eventually index racing in one of the super stock classes which is why he uses a 2 valve motor with mechanical fuel injection. He will eventually destroke it a bit which should give him a decent weight break and a doable index.

    • 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
