    So confused about Turbos. Garrett, precision, BW.

    500kW+ at the wheels, might try drag racing and roll racing so I break less things :D

    According to this exaggerated chart by Garrett, we could "assume" it is possible, given we've seen the Gen 1 GTX3582 do close to those numbers in a real world scenario.

    Nah, you're cool, you actually tune cars so respect what you say. It's when internet mechanics or internet faux tuners start pushing their agenda on others is when it's not cool, especially when they've never tuned a single thing.

    Would love to know how they come to those figures. A 3076 gen 1 makes more than a 3576. What on earth is that? Turbine side as it gets bigger makes less grunt. 🧐

    Run an OPR and an oil filter and they will last, at least they won't shit out turbine wheels if you accidentally over speed them :)

    Have been over speeding my 8374 by a few 1000 rpm since the day it was put on 2017. Was pulled off a few weeks ago in perfect condition. No shaft play, no missing turbine wheel. 🤷‍♂️

    PPG Sequential

    in Drivetrain and transmission

    Posted

    Guys have to so be a bit realistic about what they expect their equipment to hold. The GTR scene has gone farken loopy with all this “1200 whp GTR street driven, does high 8’s” rubbish. 

    Between YouTube, Instagram or any other “look at me” social media dribble, everyone wants to be a super star and out donkey swing the next guy.

    A 600 kw GTR is ridiculously fast (mid 9 seconds or whatever) and if built right can stop, turn AND go. Anything faster that than really becomes a 1 trick pony. To have a manually shifted 900 kw GTR with sticky tyres, on a prepped track launching at god knows what RPM in a heavy car, is it any wonder why the drive lines fail? There is no give and all that grunt/shock load has to go somewhere.

    Come back down to earth!

    PPG Sequential

    What I can't get my head around with the PPG sequential is the fact that they went ahead and used a design that fits the standard case. This completely turned me off after getting my quote from them for $23.5k assembled in a standard housing which I would supply.

    Going to a custom housing like a Holinger, Albins or Samsonas allows them to move the main and counter shafts outwards away from each other, increasing gear diameter, therefore more material and increasing gear strength - if you are comparing between the same gear materials of course.

    The OS88 did this to increase strength, but are obviously made out of inferior materials in their gears compared to the sequentials mentioned, or else every OS88 you come across wouldn't have been recently rebuilt or in need if a rebuild.

    @Piggaz@r32-25t So Paul, Brett and anyone else with a PPG sequential, with the above mentioned do you honestly think the PPG is even close to the same league strength wise as the 3 sequential transmissions I mentioned ? What made you guys want to get one ? Don't get me wrong, I think Pfitzner is a fantastic company and have a fantastic product - but they still don't have a deep professional competition motorsport proven use like Albins or Holinger in racing.

    Genuinely and honestly, not because you own one, but what do you think objectively their long term reliability is in comparison ? Do you think it really is the best sequential for a GTR on the market ?

    Genuinely asking, I'm not having a go at anyone's choice of transmission.

    I totally agree and this was my beef with them when they first released the sequential. I spent many hours on the phone with PPG when I was originally going to go down the 5 speed dog box path and they said themselves the issue is with the 5 speed box IS the housing.... then they make a sequential out of the 5 speed box. WTF?

    Got the OS88 in the car and removed it after 300 kms. Didn’t like it. At the time (mid 2017) I don’t think the samsonas box was a thing yet so it was the PPG, OS88, Holinger, Albins that you needed to take a grinder to the car or back to a 5 speed which is just NOT an option.

    IF I was doing it today, I think the Samsonas box would be the pick. Suck up the scaffolding gear lever (surely they can do better here) and cop the noise on the chin. With cranky diffs, pumps and whatever else is going on, what’s a bit of extra “character”?

    It looks like PPG have released a billet housing now. Unsure if it’s any bigger or it’s just shinier.

    I have had NO problems with the PPG box, it’s been great. Put all the trim around the shifter and it’s pretty damn quiet, shifts well, no oil spewing out the gear case or any other dumb problems.

    An issue is with these types of boxes (sequentials in general) that guys want to run 1500 whp through them and then wonder why they break. If you run a reasonable amount of power through them <600 Wkw (I use the term reasonable loosely here because 600 wkw is a crazy amount of power) there shouldn’t be any issues.

    8474 didn't deliver anything special in my application, 2.8L high comp RB26 2.8l.  WIth a 1.05 rear, compared to the 9180 it behaved very similar.  It was quite more eager to come onto power faster on full throttle in 1st and 2nd gear, but it felt so restricted as soon as you got it moving.  The 9180 didn't feel like it was choking the engine as much, overall felt much more healthy and a better match  

    The 9274 was the next turbo I was going to try, but it looked like it would just be an extension of the drawbacks I had with the 8474.  74mm wheel simply too restrictive to swallow all the flow the larger compressor can give.  Wasn't impressed with the 9280 from very limited testing I done

    Have you fixed your exhaust that’s way too small yet?
