sump looks good mate. thanks for posting that up. I just got some tomei baffles for mine. I was origionally going to use the trust sump as they look nice and ricey and say trust on the bottom, but i just liked the simple design of the tomei kit. though the trust kit does ad more capacity and with the change in sump shape i guess they don't need the same type of baffles as the standard shape sump does. the only other thing i didn't like about the trust one was how low they hang, if you knocked it on a curb at the track could be trouble...

Thats the thing, In my sumps I get alot of the extra capacity by going wider not just deeper, the trust one in my eyes is a rip, I can fold the same square box of aluminium in 3mm sheet in about 20 minutes at around $15 for the ally.... I make my own baffle/trapdoors as my sumps are deeper they need to be a custom height, the tomie, arc baffle kits I have seen are really good though and I would recommend them to anyone who wants t go weekend circuit racing!!!! As a side note more oil means cooler oil also, so there are a few different benefits to extra capacity.

Although I can recall SK boasting he can do a dry sump for $500, $2K is getting more realistic.... but $4K is a more likely figure.

Hang on, I remember doing one for $1500, but that was only a 3 stage.

I acknowledge posting that I could do a dry sump system for $500 MORE than a decent wet sump.

Moving on...............

Personally I wouldn't have a dry sump system in my road GTR, but I wouldn't have a 650 bhp road car anyway. That's a track car that just happens to be still registered.

The comparison between the cost of a decent wet sump system with a proper high flow oil pump plus decent cylinder head oil control and a dry sump system is not as great as some people would have us believe. For a start the cost of fabricating a dry sump pan for a GTR is much cheaper than fabricating a decent wet sump for a GTR, with wings, baffles and one way doors having to be made.

The real problem is the ludicrous prices charged for upgraded/aftermarket oil pumps (I don't consider N1 pumps to be aftermarket). Then there are the even more ludricous costs of the adaptor collar required for early RB26 and all R20/RB25/RB30 cranks.

Add it up and I don't think there will be much difference in TOTAL cost, but there sure as hell is a big difference in effectivenes.

:P cheers :)

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.

      Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
