Blown Motor, Engine Rebuild/Replacement.

Z&I

Yes it is a bit ironic, isn't it ... ... Spinning the wheels and going sideways doesn't increase forward progress.

The (digital) Race Logic does have an available option that will allow you to increase the max slip rate from 25% to 50%.
Combine that with setting the initial(TC) engagement to 3500 rpm or so and you have a safety buffer that will allow you to still be aggressive and will react quicker than you in an emergency situation ... at least in theory.
That was one of the things I wanted to try before the motor went poof.

It still all boils down to knowing your car and maximizing available traction in any given circumstance.

From the GTM site:

Nismo Final Drive 3.917 as opposed to OEM 4.08 (MT)

https://www.gtmotorsports.com/produc...cat=270&page=2

Better transfer of power to the pavement / traction ?
Anybody have experience with this ?

the factory final drive is 3.69, 3.9 would be moving to a smaller final drive gear and worse for traction with boost. what you want is the 350z final drive (3.53) or the automatic final drive (3.3).

Will check in to this ... THANKS ! ... Ahhhhh : At last !!!
Makes perfect sense to go to a different ratio when drastically increasing the power... just didn't know where to go.

...wuz under the impression that my '09 6MT was 4.08 Final Drive ...
need to double check my info.

Hello esfourteen

Did a little more legwork ...

Checked the Nissan stats for the 370z and you are right ... 3.69 is OEM factory final drive.
Here comes the curve ball ...

After having owned the car for about 6 months - I - (along with my mechanic) decided on the Stillen SC'r for more streetable power.

Some wheel spinning later thanks to the added HP ... we decided to upgrade the OEM hydraulic LSD to the Quaife 1.5 LSD.

The supposed final drive was to be 4.08 ... and that's what I thought it was for 3 years even tho' I wasn't able to detect any discernable difference in actual use.

Turns out that the OEM final drive gears hadn't been changed at all, and the car was still OEM at 3.69.

I wish I would have know this long long ago.

Thanks for your input - it gave me that Eureka moment of understanding.
I will now see how the car runs with the built motor and new SC'r.

First need to know the shift points especially at the max in 4th when I get it to the track again.

Then decide on the final drive based on what the car does at the track ...

Hopefully I might be able to do that this season.

Again, thanks for looking deeper in to my question and coming up with the answer I needed.
