That PPG set is not a synchro box. It's dog gears. Just so you know, Pete. :)

Hi Paul, sent off for some info, dog gears, sequential gears they would be like ridding a bike again and that is OK but I guess they are crappy for DD use.

Saw a Video with a bloke in a parking lot and not having fun at parking , so I guess they can be a pain.

Just said to Joey that I might just get the build done with what I have and see what happens or give it a miss :)

On my laptop now so I cannot PM you.

Pete

I'm running 450kw at wheels on e85 through a stock box, previously at 410kw went to the drags, no issues

Another drag night coming up on the 16th July

Should hold up, box doesn't crunch or anything might just be lucky

Your in the zone now, just a matter of time.

Would you be happy with a dog box or sequential box in the car?

I think if I was going to do either I would have to drive them but the sequential sounds , well interesting and I would love to try it, maybe not buy it,haha

Thing is, everyone seems "ok" with the gearbox "constantly" failing.

Is it not a big deal to get it rebuilt?

Is it worth going for smaller turbos (-9/GTSS) to specifically avoid this weak point?

Second hand boxes are pretty cheap $600-$1000. And only about $1k give or take to rebuild depending on what's smashed.

Less power is not an option once you've been there.

Broken boxes being a big problem and magnified when using 3 and 4 plate clutches,so I will ditch the Quad and going for a Twin, but what Twin to use on a torquey R34GTR.

There are a few that were recommended to me..Coppermix C Spec twin seems to be on the top of the list.

What about carbon types?

Pete,

Jim Berry full monty with organic plate works for me in 26/30 GTR 350rwkw @ 6250 but then I don't 'launch' so may not suit your needs.

Back OT I spoke to Award about gbox strength recently, their view was that a good margin of failures occur due to:

'nut that holds the wheel'

downshifts rather than upshifts

Going with the Super Coppermix Twin Plate Clutch, done enough looking my head is going to fall off and have had some great help from some of the blokes on this site :)

I guess I am going to be that NUT and loving it.

    • 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
