Getting to the point of my build where I'm finalising my drivetrain options. Was always planning on going for a PPG 5 speed dog box but have seen a few second hand OS88 show up which are priced very competitively. Each box has its pros and cons, I know. Car will be a daily driver 90% of the time. 700-800hp on 98ron. On the track (drag and rolling racing) will switch to E85 and hope to see 1100-1200hp. 

Which one of the 2 options do you guys think will do a better job?

I say the PPG 5 speed H pattern, but I think you really need to hear from some OS88 end users to get a better picture. I would be interested to hear who is still running one and their opinions on them.

OS88 is a very old and dated design. No gear position sensor, just a switch for the gear display, no strain gauge either. Quite agricultural as well. 

Mine lasted 300 kms and then pulled out and moved on for a PPG sequential, no comparison between them.

    • I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.
    • From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.
    • I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

    • Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
