I was advised at one point to go find a local spring works (yellow pages) and they can make up anything you need ;)

was all too hard for me though

I was going to suggest that. Pretty much any spring that fits in there without falling over will do the trick anyway. And shimming them as already suggested will raise the pressure somewhat. Its all very easy.

Lol at lending ya car. I sure as hell wouldn't. I only let the missus take it anywhere.

I don't have a problem with mates driving my car, after all it's just a car. I often take my car to the skidpan where I let my mates have a go, it's something I think everyone who has an appreciation of cars should experience. But perhaps not at 400rwhp when they are used to driving beaten up Honda Civics, etc.

On the skid pan wouldn't be as bad cos you got your eye on it and also they aren't on the road with the opportunity to see how fast it goes or something stupid.

I loaned my skyline once and it came back with 7800 rpm on the hand controller and 170 kph. Plus the clutch stunk and I'm sure that's why it is slipping now. I loaned my commodore once as well and the guy got a speeding ticket and ripped the front bumper off on a kerb and blew a hole in the radiator which only happened at the time from revving the crap out of it.

You say its just a car but for me it is months of work and saving. If someone really appreciates a car they can work their arse off and save their money and get their own like most people do. But hey that's just me biggrin.gif

Yeh I don't just approach people on the street and hand them the keys lol :P I have a close group of friends, would trust them with far more than my car. They could easily get their own, but it's just not something they want. They enjoy driving it but they see the headaches I have with it sometimes (like the hot start issue) and it just isn't for them. Or they have a different taste in cars, eg my mate has a '78 Escort that he is building. We all have our own tastes, mine just happens to be set up for track work :P

Anyway, didn't mean to go so off topic whistling.gif

I hear ya. It's good to have mates you can trust like that. I've only been in perth for ten months so I don't know many people here. On topic now, why don't you try putting some big washers under your 7 psi spring and seeing how much it raises the boost by. If your car isn't set up for the gate yet we can try it out on my car sometime.

on this topic, does anyone know if the tomei 270 8.8mm lift cams would be okay for a stock rb25 hydro and stock springs?

This is an external wastegate thread, were discussing spring pressure in the gate and target boost.

Your probably looking for another thread, however I think the duration has nothing to do with how well it will work as its more the lift. IMHO the stock springs are shit to begin with, I would ditch them in a mad hurry.

or better yet lets just ditch the whole engine for one with a toyota badge...right?

Hanaldo: speaking with Sean from Allstar I was told to downgrade my spring, had a 7 and 14 in my 48 progate to just the 14 and use my avcr to run what ever high boost, aiming for 25psi, reason being the ecu can pull boost out if something is overheating or going wrong,

I was under the impression of getting the spring pressure as close to the target boost as possible too,

it depends on your setup, with internal gate and an actuator getting one close to your target boost is more important than with external gate as with external you can use both ports to hold the gate shut until a few psi before your target boost.

i say see how you go with your current spring and if its not enough you can always change it later.

ive got some Turbosmart wastegate springs laying around is interested in them, one has yellow paint (largest), one has red (medium) and another i think has orange (small) paint sprayed on it

im not sure what psi they are, they have been sitting in my room for about 4 years and have some surface rust on them but nothing major

Haha well those sound like they are from a Pro-Gate or Power-Gate, so they wouldn't fit my application. The red one might fit the Comp-Gate, is it red and brown or red and black? In case you're interested, the yellow one would be a 14psi middle spring, and the red one would be either an 11psi middle spring or a 12psi outer spring. If the red one is smaller than the yellow one then it's probably from a gate like mine.

I saw a spring at work today which looks like it would fit. The bloke said I can have it soon when he replaces it with a new one soon. It is very hard to compress by hand. I succeeded in compressing it about 3mm. I'm keen to try it. Just by the feel of it I'd say it is good for 20 psi or more by itself

      Unpeeling the Orange

      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.
