Shift points

[Scott4957]

Did quite a bit of searching but found no definitive answer, likely because there really isn't one. Working through some revisions with Torrie and am curious where I should have him set the shift points on the MKS. They seem quite low right now.

1-2 5200
2-3 5200
3-4 5600

Just taking a look at other logs I see most are higher like 6k. Any suggestions on a stock non PP drive train? Have not had it on the dyno so nothing to go off of there.

Thanks,
Scott

Torrie had the 2013 setup to shift that way.

It never felt right but I couldn't argue with the results.

I assume it is a result of optimizing peak tq/hp, trans shift capabilities/reaction times and traction.

[Scott4957]

Yeah that is what I figured. FoMoCoSHO, I was looking at your 2015 log, that is where I say 6k.

That's substantially different. From what I understand you want to shift just past peak horsepower landing at a point just prior to peak horsepower after the shift. Essentially at equal points on either side of the curve.  I haven't looked an enough dyno charts to know where that is on this car, let alone where that is in each gear.

If you don't have a cai that may be the reason. Cai doesn't really make power bit it does seem to carry it longer. I was on the OEM box on the 2013.

I assure you power is falling off hard at 6200.

I wouldnt over think it...6k seems to be nice..the turbo has a hard time above 6k...and even with a bigger turbo i dont know if this is a rev happy motor anyway

Yeah I agree, its not a big deal to move it around. I could have him bump it all up to 5800, it will shift by about 6k and see how it does. If it doesn't show at the track or on the logs then I can always move it back.

You had good results with the lower shift points?

Car had quite a few revisions after that weren't track tested due to unexpected trade in. It was pretty nasty.

What were the shift points on either of the cars? Were they low or like mine at 6200rpm?
