I added to my previous post with some figures. :thumbsup:

The S13 diff isn't a drop in due to its different housing. So again you will be forced to swap the ratio from that diff in to your housing. Of which will blow out ot $600 odd by the time you buy the diff and have it fitted.

thats all i want. drop in the centre ratio into my housing :thumbsup:

Darren,

Another Darren with his R31 470rwkw here in Adelaide has played with a few different diff ratio's. With the auto. He settled on the VLT's 3.45:1. He said it heaps a shit loads with wheelspin. 165km/h at the top end of third is not that crash hot.

Also.. Gave you a wave in a red vn Dungadoor last Sat I think it was; south end of diag road.

yea i thought it was you.

The other darren has a rigid rear end so that doesnt help me much.

  • 3 weeks later...

When I originally purchased my car it dyno'd at 189rwkw and would light up the tyres a little too easily. This was great fun for the first couple of weeks but it was getting ridiculous after that. At the same time I was also suspect of the wheel alignment as there was slight evidence of uneven tyre wear.

Decided to get a full 4 wheel alignment done and it transformed the rear end completely. Now you need to make a much bigger effort to break loose the rear tyres on take off.

The diff cradle bushes can have a huge effect on this also, can't they? Have you checked to see whether yours are worn or could they have been replaced with aftermarket bushes at some stage which may offer less compliance and a greater tendency to break traction (hence the reason that drifters use them)?

These are a couple of cheap things to check and/or change if neccesary which both can have a dramatic effect on your rear end grip.

Cheers, Mike

i run brand new 265/35/18 inch hankooks mate :huh:

moreso for reducing revs at 100kph on the freeway

some better tyres, a decent alignment and maybe some pineapples to adjust drive angle you will be sweet. Cats drift car with 280rwkw (old SR20) with decent 235's would pull throught the gears with minimal wheelspin.... its all in the contact pactch and the quality of tyre providing that contact patch... forget diff ratio's... even with 4.37 we had awesome grip... so with only 209rwkw and 4.1's you should be laughing.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
