Im getting a R33 gts-t with just an N1 exhaust and Apexi Super AFC. How much boost can i safely run without an Intercooler and how much once i get an intercooler? And approx. how much power should i expect?

Thanks

10-12psi mate, same as everyone else :bunny:

Depends what you hit Rich & Retard every car is different... you'll know when you do :D

Power without an ECU, around 160-180rwkw. Could be a bit less. Either way around that.

Checkout the RB25 dyno thread sticky, it pretty much gives you expectations to work from

yeah 12psi or so, i have 4 settings on my boost controller, 7,9, 12 and 14.9 psi. YEEEEPPP 14.9 psi. BUT i only use this when i want to absolutly cane it for a short burst, plus i ensure i monitor teh bosst with my foot.

I don't expect the turbo to last tooo long, but i am only using 14.9 psi for 10 second burts or so.

  • 2 weeks later...
so 11-12psi on stock turbo is fine?

Generally speaking yes this is fine. But for people to say yeah it wont be a problem isnt entirely right. Some peoples turbo have let go at less then this its really luck of the draw. The cars arent new these days so your pushing factory items alot harder then they were intended to. At the end of the day 11 - 12 is generally safe enough but its not to say when you put it on 11 or 12 that it wont shit itself in the first week.

Just a thought.

Doesn't the R33 Turbo have a small stock intercooler? Or are you referring to an after market intercooler?

He is refering to how much he can run without a better Intercooler. They all have factory intercoolers just arent particularly efficient at much more then standard boost, power.

wats 11-12 psi on guage reading... is that 0.7?

You will want to get yourself a guage reading in psi otherwise if you are intent on trying to run 12psi you will quite possibly run more without realising. A cheap mechanical guage will be all you need. Id keep it to 10psi myself but either way :)

yes it does, a very small side mount intercooler. if i were you, go for the r34 smic, they are slightly bigger and will be sufficient for 200rwkws

cheers

    • 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.
