In a few weeks i am getting my new turbos put into my car (R33 GTR) :blink: They are GT2860r-7's. I am also getting my exhaust replaced at the same time. I have Tomei dumps, 3 inch Do-Luck front pipes, 3.5 inch cat, and a 3.5inch Do-Luck cat back.

My car is stock at the moment and was dynoed at 181KW at all 4.

My question is what sort of power increase can i expect from this upgrade? And what PSI/BAR should my turbos be set at? I assume since i dont have a manual or electronic boost controller that the boost can be set on the actuators? Im thinking 1 BAR will be fine and still keep my engine in good safe working order.

Cheers for any help :down:

18-20psi you should see around 300 at all four with management.

You make no mention of management however, so if you dont have any...

1bar - 250 at all four.

Bit of a waste running 1bar with those turbos though, get some management

The plan is to get a Power FC when i have the money ready. Im just trying to get my car back on the road after it being off the road for 6 months with stuffed turbos.

I dont really like the idea of being to close to 300KW just for the fact that if my engine goes i cant afford to rebuild it at the moment im trying to save for a house aswell :blink:

  • 3 weeks later...
I finally got my car back today with everything fitted and no more exhaust smoke either :)

I managed to get 232awkw @ 14PSI

That is great for a stock GTR.....

PFC will only get you another 20 to 30 AWKW's.....

I run the gt-ss turbos on my stock r32 gtr at 307rwkw with a safe tune and blew up no.6 piston within 3000km. Don't do it mate. Run about 270-280rwkw to be safe.

Cheers,

Al

wahhhtttttttttttt im scared to install my GT2860 -5s now ;)

once you get the power FC you should see an easy 290-300rwkw with 18psi..i think that would be safe. 232awkw is what you would expect from standard turbo's at 14psi

Cooper,

You in Adelaide mate? Whos doing the work on your car?

Cheers,

Big Mike

Yeah im in Adelaide, Graham West Workshop (Adelaide Performance Engineers) did the work.

If i wanted 16 PSI would it be as easy as adjusting the nuts on the actuators? since i dont have a boost controller. How much would i have to wind them out?

    • 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.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
