2018 year of the drivetrain?

They have a cast vband twin scroll manifold they showed. I didn't notice any wastegate or O2 provisions, so chances are it has some time before it will be done. Maybe end of the year or so is my guess.

@Chris@VargasTurboTech posted some pics of the o2 and wastegate setup on Facebook. Maybe he can start a new thread here to keep us informed.

I don't get all the vband connections on all the kits. I would think a simple T3 or T4 would be more desirable. Can only bolt together in one orientation and less potential for fitment issues. Easier to bolt on too than holding the turbo with one hand and trying to get a vband fit with the other too. Hell, I wish my motiv manifold had a bolted flange versus the vband just for ease of install.

V-bands have pros and cons:

Pro - infinite adjustability

Con - infinite adjustability

There's always a tradeoff! lol

People have been making silly power on the N54 platform for years. That's nothing new. 700, 800, 900hp is no shocker. The thing that has gotten very little attention until last year was the drive train. Putting that power down and using it effectively. I think AD and xHP both have gotten the ball rolling last year. AD has some bugs to work out on their 4l kit and xHP basically allowed the 6at to be useful.

This year MHD is bringing out their shift bog elimination and on the DCT side there's some interesting things cooking. I'm really interested to see where this goes.

Even a 3600lb car at 700hp, if you are able to cut a 1.4sec 60ft and shift decently you have a 9sec car. Not to mention if you have more hp than that or less weight. But when you have a 6at that takes .4sec to shift (with xHP stage 3) and you need to go through 3 shifts to complete a 1/4mi you have lost 1.2sec of acceleration time right there! Or the 6mt bogging after every shift...

I think enough smart people have turned their gaze over to the drive train that we will see some interesting things soon.

With .4sec shifts. What would be ideal or perfect.
Is there something in the future coming to correct this. Is this a ecu fix or mechanical fix.

All new performance autos are less than .1sec shift times. We need to adopt our DCT with .04sec shifts.

I thought @Chris@VargasTurboTech said Q2 in the 2108 teaser thread?

Eh, whats a quarter or two in the span of 90 years, right?

Before end of year -when it's closer and we have more info and some results to share, I won't be shy.

I always thought our transmission shifted in 200 or 100 ms bmw advertised faster than blink of eye and said 200 is that bs and does anyone know how fast pd transmissions shift or are they not any faster?

xHP Stage 3/4 is what you'd want to compare.

M3 DCT is 90ms and I think non ‘M was measured as 120

I meant propusive dynamic as its recalibrated I don't know if it sifts faster though

 

[Rob09msport]

Do you think xhp is still .4sec or is .4sec even accurate

xHP Stage 3/4 is what you'd want to compare.
