Hey guys. I'm in Adelaide and planning on road tripping to Perth next sometime early next year.

I was just wondering, in the middle of nowhere they've got this "opel fuel" stuff. What exactly is it and will it be ok for the Stag??

Gee there is so much crap goes on here about fuel..... a std Stagea will run on 91 octane no problem. Unless you hear pinging from any engine (except if it has retarded ignition) then you are getting complete detonation.

And that means that it is OK. In fact you won't get any more power from higher octane unless you re-map and re-tune your engine, all higher octane lets you do is run more advance on the timing, higher compression or more boost.

Let us know when you're coming, we'll get a cruise happening.

Stagea is made to run on 100 octane. If you put a lower grade fuel in the ecu will adjust to avoid detonation but performance will suffer. Just remember when you get back to 98 to reset the ecu (disconnect it from power) so that it can adjust to the better fuel.

Well you won't get high!! if you plan on sniffing the opal !! :) but you could just take some octane booster with you to add to opal fuel like 104+ octane boooster :)

    • 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
