Ppg Gearbox

[PJ.]

Stillway in Japan make a gear shifter that locks out 1st and might be applicable in this case.

Thanks mate, trying to find the product but not having much luck. Will def buy one! Do you know of any in aus?

Has anyone on here used an Ikeya Formula sequential shifter with a ppg box?

PJ. it's been tested before by my friend on his straight cut dogbox and the impression is poor.

ikeya shifter not recommended for gtr dog box transmissions

Yes, the Ikeya is no good with the dog boxes.

The Stillway shifter works by locking out the gear that you shift up from. ie, 1st to 2nd cant go back into 1st; 2nd to 3rd, cant go back into 2nd; etc etc. This allows you to not miss shifts as you go up through the gears and effectively becomes a 'sequential' H-pattern box. When you want to go back down though the gears, you can do so up lifting the lock ring that is on the Stillway shifter and then engage the lower gears. It is mainly aimed at drag racing so that you don't shift into, say, fifth gear when doing the 2nd to 3rd shift.

I went for a massive fang last night (on a track of course) not using the clutch for both up and downshifting and I'm really loving this box now.

My mechanics put a much firmer relocating spring in the box so it neutralises a lot harder after I pull out of second. I still use the clutch from first to second though as it seems to clunk a bit otherwise. Can't wait to drag it again now, I'm sure there has to be a tenth or two in the gear changes alone compared to the syncro box.

Do they have a hp rating on the helical dog gearsets for a GT-R/GTS-T box?

[PJ.]

took the car down to the drags with the same settings, only difference was the box. Went from 133.96 mph to 137.30 trap speed Not using the clutch, faster shifts = more time on power.

What 60' and et?

Shocking 1.955 60ft, track was prepped to the max so I needed to turn the anti-lag up a few more psi but didn't have the laptop handy at the time. 10.658 @ 137.60

I bogged every run! Prior to that I ran a 1.69 60ft so next time I go out, it's on!

Im happy to say i fixed my oil being pumped out the breather pipe problem on my ppg gearbox... What i did was add another breather pipe to the inspection plate on the top of the box where you can see the selector plate... I then ran both breathers up to a high point in the engine bay and now have no loss of oil from either pipes no mater how hard its being driven...
