Hi
Will the clutch from the 150 HP TDIPD also fit in my 115 HP TDIPD?
Because I've heard from many people that the clutch can slip after a 'chiptuning'. The one with 150 HP should be able to handle it, right? |

Hi,
The clutch should actually fit, as VW places importance on compatibility.
Otherwise, it wouldn't be possible to swap a 5-speed transmission for a 6-speed transmission.
Whether a clutch replacement is necessary would definitely be decided after the tuning.
And then only as a kit (clutch disc, pressure plate, release lever)
Furthermore, you can tell where the limit is by observing the slipping, thus protecting the parts that show weakness after the clutch.
Greetings

Hi,
I would be very careful about compatibility with clutches, I've had quite a few problems with that. The best thing to do is to go to VW and ask if the two engines have the same flywheel. If that's the case, the clutch is likely to be working properly as well.

Hi!
The 150 PS PD engine only has 10 Newton-meters more than the 115 PS engine!!! Therefore, the load on the clutch is almost the same for both. Possibly, the clutches are also the same or very similar in their load-bearing capacity. I don't think you will gain anything with a different, expensive clutch. Your tuner usually tunes the chip to the vehicle. If there were major problems with defects, it would at least be discussed in our forum. There are better and worse chips, but generally, the unit can handle the performance increase.
Best regards, Uwe |

Nun, der 150 PS Motor hat 320 Nm, wenn ich mich nicht irre. Mein PD hat das Baujahr 2001 und hat laut Handbuch nur 285 Nm !!!
Let's take a look, first let's chip the HN... |

Hi!
Okay, there are two versions of the PD engine with 115 hp, one with 285 and one with 310 Nm! The 285 often shows such a wide range of performance that the differences are often negligible.

Aha, yes, I've also heard that there are versions with 285 and 310 Nm. But why does VW build the same engine with different torque figures? Is it possibly due to the gearbox? I already have the 6-speed version... I was also once on a performance test bench near me, where I had 124.3 hp  (I don't know why the torque wasn't measured!!) without my current air filter and Group A exhaust... I also removed the cat now! Now I'm leaving my neighbor in the dust (he has the 130PS TDIPD, but the standard one, I have the Vari), and he's actually getting better...  |

Hi!
So, warum es den 115er mit 2 verschiedenen Nm gibt, weiß ich glaube ich nur VW selbst. Die Motoren unterscheiden sich erheblich in Bezug auf Dinge, die die Lebensdauer betreffen. Die 285er Getriebe sind nicht für die höhere Belastung ausgelegt (Chiptuner beweisen, dass die zusätzliche Leistung in der Praxis durchaus bewältigt werden kann). Das Drehmoment kannst Du aus Deinem Prüfstandergebnis berechnen. KW = Nm x U/min x 9549
Your 6-speed gear seems to indicate the 310 model...
What do you mean by "Vari"?
Best regards, Uwe |

Hello,
Also auch der 115 PS, 285 Nm Motor (AJM) hat ein 6-Gang Getriebe. Tschüss

Oh, I'm having trouble understanding your formula ???
KW(85) = Nm(285) x U/min(4000) x 9549
That's coming out completely different for me!!! Das sollten meine Original Motorwerte sein die in Klammern... |

The specified torque of 285 Nm does not apply at 4000 RPM!
After applying the formula, you can determine the torque the engine produces at a specific speed, if you know the appropriate power. You need to look at your diagram, as you need to find the performance for, for example, 2000 RPM, and then calculate.
Or simply hold the torque at 4000, which is LOWER than that at, for example, 2000, because the maximum torque is in the 2000 range.

Hey Diesel fans...
You're using those bird-specific formulas...
Okay, for a rough estimate, I would first use the formula:
P=2*Pi*Moment*Drehzahl
use.
Entering values in SI units is very important!!
Speak: P = power in [ W ]
Moment: [ Nm ]
n = Speed in [ 1/s ]

Well, that's the problem, my diagram only shows the performance and the SPEED!!!! NOTHING about RPMs... well, I'll just have to calculate a few times with different estimated RPMs between 1750 and 2500 1/min... |

Hey Mr. X
so
Your performance graph is power (kW) versus speed (V).
Okay...
the formulas you need are...
Wheel Speed = Engine Speed / (Gear Ratio * Overdrive Ratio)
Speed = 2 * Pi * Wheel RPM * Dynamic Wheel Diameter
Solve the upper formula based on motor speed and solve the lower formula based on wheel speed.
Interlock and you'll have your engine RPM...
You can get the number of gears and wheel diameter from the professional guys here.
Best regards from Lake Constance!!
Have fun calculating!! |

Hi,
I've been messing around with UWE's formula a bit!
So, I used the power as specified in the manual: 85kW; 285Nm at 1900 1/min....
1. use instead of kW only W !!!
2. I reversed the formula, specifically;
W / 1/min / Nm = X
85000 / 1900 / 285 = 0.157
3. The number 9549 is incorrect, it should be 0.157
If I now use my dynamometer, I get approximately 305 Nm...
91000 / 1900 / 0.157 = 305 Nm !!!
I just took the same RPM as specified in the manual, but it seems to be...
But I will get a proper dynamometer where power and torque can be accurately measured...
