I see greenline does them.

"Mines rb26 shore pro 2". They were about $1600 when I was looking, that includes buckets though. There isn't a hell of a lot of result out there with them, I'd say that would be due to price.

I was going to run them before I decided to go even more aggressive.

If it's for hillclimb i wouldn't even go -5's. Go -7's and put E85 through it. Though that's just me.

Concur... Most hillclimbs being lower speed (under 140km/h), -5 are not the right selection for such escapades.

So if -5s are already there you want the max response you can, stock cams and some cam gears set to bring on boost early as possible without worrying about the peak figure as it's the middle area that's going to bring home the silveware

haven't got the -5 as yet just doing my research and from reading some forum threads it seems that the -7's come in earlier but really drop off at around 7000revs is this correct?

I like a high revving engine would get the -7 but would prefer to be changing gear closer to 8000revs ....

Thanks for the info Piggaz found them on green line your right not cheap but i will speak to my tuners and if they think there worth getting i will get them..

nope. Mine Hold 21PSI all day. Depends on the engine i suppose. Why do you want to change at 8000RPM? there is no reason for that. That's just an engine waiting to go bang sitting on the redline like that. Until you forge the engine don't even go near that. Even then i wouldn't.

Anyway if you are planning on doing hillclimbs get the -7's. You will get much faster times with them. And they can still run decent power. I'm sitting at 320KW on 98. To go -5's for hillclimb is a huge waste of moneys.

thanks it tuned for e85 at the moment.. thats some pretty good numbers ok then so its -7's is it worth also getting the Tomei exhaust manifolds and extension dumps at the sometime ?

No to the exhaust manifolds (between the engine and the turbo) Yes to the dumps.

Why 7's & not 9's?

to be honest I'm not too familiar with either just doing my research.. i thought the -7's are bigger and would get more power than the -9 and thats why..

DEFINATELY no to the exhaust manifolds. I have been two sets myself, one set didn't last 1500 km before I blew a hole in number 1 runner. That and when I put on some tickled stockers there was no difference on the dyno or the road for that matter. However, they make a great paper weight or a nice looking door stop.

-9's will net a fraction more.

Good work. I only went through one set but I did manage to crack both of them. Winning.

No to manifolds man. I'm making 472 rwkw through -5's on stock manifolds, they have been matched to the head and turbine housing though.

Dumps - HPI, Tomei, Midori. Take your pick and if you want to be really fussy, match the front pipes to the dumps so there is no lip there.

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
