Ok I have the graph but no scanner but will post it up in the next few days.

Got the car back and @ 17psi it made 199.6rwkw.

makes 17psi @ 3500rpm and its an awesome ride

had it 3 days and the plugs fouled so need to replace em.

Mods are:

RB20DET

HKS 2530 + actuator

GTR Injectors

3" Dump and exaust

650x220x90mm hyperflow tube and fin cooler

hks pod

e-boost

Wolf 3d v4

The response it great and it lights the bags nicely, any questions ask away,

Also I want to take this chance to thank the following people for their help along the way.

SteveSST, Meggala, Summoner, Morgs, DoughBoy and SK. Thanks guys.

Evan

well, at first there was a problem with the coil charge the coils overheated and the car wouldnt start, so they turned the chrge down and now at anything over 17psi the car misfires because the coil isnt charged enough. Looks like i need to gut the cat and sort out that problem. However I am happy and I gotta say the 2530 is a great street turbo, any more would be overkill for the street, well in my car anyway.

im thinking about goin down the same path as you rb20-calais...xcept i want around 250rwkws is this possible with the turbo and perhaps more boost? i rekcon its awsome to have 17 psi by 3500 good work dude.

Michael

250rwkw not possible with the 2530 (a really big MAYBE if you get REALLY FAT cams and a load of head work but then i suspect you'll lose the trademark response of the turbo!!)

well, i once wanted 250rwkw as well. But its just not smart with an RB20.. for reliability and response I feel this is the best turbo to go with. If you want a lot more power you will need to upgrade the engine eventually unless you want to do things twice. Summoner has done this and had awesome reults.

250rwkw + stock RB20 = playing with fire.

Evan

Sly,

Its awesome holds 17psi all the way with my 10psi hks actuator, also the boost comes on VERY quick and i make boost below 2000rpm and it LOVES to flutter, I am very happy with it. The place who did my car did it all and the settings are 10psi, 15 and 17 ... god love SP3!!!

Thanks again I am more than happy with it!

Also Doughboy the 2530 and actuator are awesome and running like a dream together, I must say SAU has greatly benefited me in sourcing great parts off great people!

Evan

Cool bbenny, I cant wait to see!

I think the reason you made more power is because your af got to 13:1 at the top end and mine were steady 12:1.

Got new BCP6ES plugs and gapped them to 0.8mm and miss is gone but is still missing @ 17psi so i gotta regap to 0.6mm, doh!

Evan

with the 2530 (a really big MAYBE if you get REALLY FAT cams and a load of head work but then i suspect you'll lose the trademark response of the turbo!!)

There will be NO loss of response on the turbo with upgraded camshafts. In fact it does the opposite. Thats a fact jack.

in my post i was more referring to the head porting causing loss of response, as how i understand it (btw i am perfectly willing to accept i am wrong) as you port the heads for higher flow, you increase the size of the ports and therefore decrease air velocity at lower rpms which gives less response until the revs get up a bit more.

Rev i am quite happy to be corrected and i never state anything im not 100% sure of as a "fact", (i will always say i think, or i suspect, or as i understand!). Now dont take this personally as im not trying to get up you, but i find some of your responses a bit annoying, even though im pretty sure your not having a go either. I realise that you personally have done a lot of R&D for your 33 and have a lot of info to offer, maybe its just me but i sense a bit of attitude in some of your posts. My name is not jack, it just sounds a bit (ocky to me. cheers buddy :)

    • 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.
