Does A Non-locking Diff Affect The Cars Acceleration?

as topic says, my diff doesnt seem to lock anymore, and under full throttle in second it doesnt accelerate as hard anymore, would it be the diff not putting the power to the ground through both rear wheels ?

thanks

Have u changed the diff oil recently

It will really come down to road surface. Theoretically if the road has the same grip across the surface it shouldnt make much of a difference. It will only start making a difference if one side has a lack of grip then you will spin that side and it wont put power down

I imagine on normal road conditions it shouldnt really make that much of a difference. If your saying it is really noticable you may have another proble. Sure your clutch isnt slipping? even if its only slipping slightly

yea i meant on dry even surfaces, Ididnt change the oil recently, but yea in the wet the car does kick sideways anymore so the diff isnt locking up anymore like it used to

maybe the lack of power is just my engine getting old lol

Hmmm I dunno, my diff is fine and its a 1994 R33 GTST, it still locks both fine.... Perhaps its worth taking out and shimming or at least inspecting

Barring a massive failure like Driveshaft/CV which I'm pretty sure youd notice lol, my only other guess is that the diff has become lazy and you might just be able to re-shim and fix it.... Simple things first but, check the fluid. Mine was a bit funnny when i first got it and i found the fluid was low. Changed it to sme new stuff and it was fine after that

If you want to change it, I use Castrol SAF-XA (or something like that) its relatively cheap and does the job. Id recomend trying that first if it is the diff stuffing up

      That's odd, it works fine here. Try loading it on a different device or browser? It's Jack Phillips JDM, a Skyline wrecker in Victoria. Not the cheapest, but I have found them helpful to find obscure parts in AU. https://jpjdm.com/shop/index.php

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      By GTSBoy · Posted

      Yeah. I second all of the above. The only way to see that sort of voltage is if something is generating it as a side effect of being f**ked up. The other thing you could do would be to put a load onto that 30V terminal, something like a brakelamp globe. See if it pulls the voltage away comepletely or if some or all of it stays there while loaded. Will give you something of an idea about how much danger it could cause.

      I would say, you've got one hell of an underlying issue there. You're saying, coils were fully unplugged, and the fuse to that circuit was unplugged, and you measured 30v? Either something is giving you some WILD EMI, and that's an induced voltage, OR something is managing to backfeed, AND that something has problems. It could be something like the ECU if it takes power from there, and also gets power from another source IF there's an internal issue in the ECU. The way to check would be pull that fuse, unplug the coils, and then probe the ECU pins. However it could be something else doing it. Additionally, if it is something wired in, and that something is pulsing, IE a PWM circuit and it's an inductive load and doesnt have proper flyback protection, that would also do it. A possibility would be if you have something like a PWM fuel pump, it might be giving flyback voltages (dangerous to stuff!). I'd put the circuit back into its "broken" state, confirm the weird voltage is back, and then one by one unplug devices until that voltage disappears. That's a quick way to find an associated device. Otherwise I'd need to look at the wiring diagrams, and then understand any electrical mods done.   But you really should not be seeing the above issue, and really, it's indicating something is failing, and possibly why the fuse blew to begin with.

      Compressor flow comparison table

      By Lithium · Posted

      A lot of what you said there are fair observations and part of why I made that list, to make some of these things (like no advantage between the GSeries and GSeries II at PR2.4 in a lot of cases) however I'm not fully convinced by other comments.  One thing to bare in mind is that compressor flow maps are talking about MASS flow, in terms of the compressor side you shouldn't end up running more or less airflow vs another compressor map for the same advertised flow if all external environmental conditions are equivalent if the compressor efficiency is lower as that advertised mass flow takes that into consideration.   Once the intercooler becomes involved the in-plenum air temperature shouldn't be that different, either... the main thing that is likely to affect the end power is the final exhaust manifold pressure - which *WILL* go up when you run out of compressor efficiency when you run off the map earlier on the original G-Series versus G-Series II as you need to keep the gate shut to achieve similar airflow.    Also, how do you figure response based off surge line?  I've seen people claim that as an absolute fact before but am pretty sure I've seen compressors with worse surge lines actually "stand up" faster (and ironically be more likely to surge), I'm not super convinced - it's really a thing we won't easily be able to determine until people start using them.     There are some things on the maps that actually make me wonder if there is a chance that they may respond no worse... if not BETTER?!  which brings me to your next point... Why G2 have lower max rpm?  Really good question and I've been wondering about this too.  The maximum speed *AND* the compressor maps both look like what I'd normally expect if Garrett had extended the exducers out, but they claim the same inducer and exducer size for the whole range.   If you compare the speed lines between any G and G2 version the G2 speed lines support higher flow for the same compressor speed, kinda giving a pretty clear "better at pumping more air for the same speed" impression. Presumably the exducer includes any extended tip design instead of just the backplate, but nonetheless I'd love to see good pics/measurements of the G2 compressors as everything kinda points to something different about the exducer - specifically that it must be further out from the centerline, which means a lower rpm for the same max tip speed and often also results in higher pressure ratio efficiency, narrower maps, and often actually can result in better spool vs a smaller exducer for the same inducer size... no doubt partly due to the above phenomenon of needing less turbine speed to achieve the same airflow when using a smaller trim. Not sure if this is just camera angle or what, but this kinda looks interesting on the G35 990 compressor tips: Very interested to see what happens when people start testing these, and if we start getting more details about what's different.
