wats the max psi u can safely run through the standard 34 turbo?

im not wanting to upgrade that yet coz need the computer first, but i have to do something. my old 33 was making 190 atw and now driving a34 with around 140-150 atw its a big jump.

hitman did a friend of mine for 12psi. said he could get away with 14psi but its not recommended. he had supporting mods such as turbo back exhaust, apexi pfc, hks ebc, fmic and pod. he hit round 220rwkw

im running 10psi on mine atm but dynoed before mods and got 180rwkw. that was only with cat back exhaust.

Same as any other RB25 turbo

10-11psi.

rb20det

ported and polished head

fmic

walbro 255l/hr

haltech e6x

rb25 turbo

3" downpipe + exhaust

pod filter

made 320hp @ the engine with 95 octane fuel & 1 bar of boost.. should be about 230-240 @ the wheel..

Thought I'd post up my old RB20 results for all to see :)

Car consisted of:

- internally standard RB20DET (silvertop)

- s1 RB25 turbo

- china fmic + piping

- Xforce split dump pipe

- 3" front pipe

- 3" decat pipe

- 2.75" cat back into canon

- 044 pump mounted intank

- generic metal pod filter

- Greddy Profec B spec2 (haven't spent much time smoothing out the boost curve)

This was untuned running 12psi (ignore the red line, that was when we tried to run 14psi, it made ~260rwhp but started to ping up high)

Nissan Skyline 1989 R32

120000klms

190rwkw

254.4rwhp @ 13.5psi

standard injectors

R33 turbo

3inch straight through with split dump

GTR fuel pump

Fuel reg.

FMIC

Dr Drift computer

no BOV

K&N pod filter

These should give you a rough idea.

What sorta turbo is it?? like series.. t03-t04 for example.. sorry for the noob question

the turbos have no 'model' or 'series' as such.

rb20 turbo would be closer to a T25, and the R33/R34 turbo would be closer to a T28. both using T3 flanges.

    • 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.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
