That is not completely correct: Torsen doesn't have a lock rate, as it's stucture goes from 0 to 99.9% (if both wheels completely loose traction it will work as an open diff).
GRMN LSD is declared to be a little more "open" on the first phase, to help entering the curve. So I think it has different gears on Torsen leverage, basically related to wider rear wheels of the GRMN. |

You can find more information here: https://torsen.com/ask-torsen-torque...nal-questions/ I am not trying to build a GRMN 86 replica. I wanted to solve a specific problem I had, caused by bad road pavement conditions. I found that the best option would be to use the specific diff and it works perfectly. Someone might say that an OS Giken diff or other clutch plate would be better, but everyone can have its opinion here. What I can say for sure is that GRMN spent a lot of R&D to build the specific diff and yes it makes a difference. Another thing to know is that Torsen (JTEKT Corporation) is actually owned by Toyota, so they know what they are doing. |

This is what I said, you were talking of lock rate not torque bias ratio, that's a completely different thing...

It looks that you still don't understand, but you are not the first nor the last. GRMN 86 differential has nothing to do with the wider wheels or about being more "open" like you said.

But as you mentioned, the GRMN unit works best for you and the specific problem you had. That’s fine. If it works, it works.

But Some work need to be done to make it run correctly Otherwise aftermarket ecu can bypass some sensor to activate the throttle plate inside to switch the long runner or short runner |

Short length runners are for high rpm power and long length runners for mid rpm torque. This is a high quality factory spec'd intake manifold for getting a wider torque curve from this engine .
