Nice! Glad to hear that… It better be out by the spring… lol
“IF”?
You don’t think there’s any merit to the claims that it’s not happening for the 3.0 do you? I think it’s bunk. Seems to be originating from the twin-charge crew.
Say what!!!

I call bunk, but what do I know :-X
Wasn’t this being drummed up by cornedoutapb, aka 10secs4?
I’d be shocked if they scrapped the blower for the B8.
Lol “IF” it comes out in the spring. nice redirect sak!
It was a little while back, but it was repeated recently by someone I thought would know a little.
Arin asked in the email why someone would think the bigger blower makes less torque. I suggested people are looking at superchargers as if they’re turbochargers, where the bigger turbo often helps top end at the cost of low end torque. They’re not turbochargers of course…so it’s definitely puzzling why that rumour keeps getting floated.
Even if it was true. Stock B8 S4 makes about 300 WTQ (and around 300 WHP). Stage 2 makes what…350-360 WTQ (and around 360 WHP)?
Let’s say the TVSr1740 makes 300 WTQ, and 500 WHP. Do you really think people are going to be disappointed???!!! I don’t.
Put it another way.
In the blue corner is a stage 2 B8 S4 on race gas that makes around 390 WTQ and 415 WHP.
In the red corner is a differnt car on pump gas that makes 365 WTQ and 500 WHP.
They weigh the same, are both manual, and both have nice modlists.
Which car is going to win every single race, every single time? The red corner. Is the red corner car owner saying ‘yeah, I won by 5 car lengths, but I sure wish I could lose all the races and be slower but have 25 more WTQ’
No.
Even if the B8 S4 with the 1740 gives you the numbers that ficitious red corner car gives, is anyone going to be disappointed? lol.
So that whole theory is a crock, likely spread by APR’s competitors.
Are you saying you believe or don’t believe it will give you less torque? It may, but not for the reasons you mention, not with a roots.
It would be because the bigger blower has more parasitic loss. So you’d reach a point of diminishing returns lets say for example:
you use 30 hp more to drive the bigger blower at 20000 rpm and 1700 kg/hr, so on a 50 hp gain, you’d only end up netting 20 hp more. And then you have the extra heat and weight to deal with that would also be retarding timing and worsening the CG and balance of the car even more. Diminishing returns, sure it’s possible. These are definite reasons to stick with a stage II setup. But keep in mind we’re already at the limit or beyond in terms of blower RPM and PR for the 1320.
The 1740 should be able to handle a higher PR though. I don’t think the 1740 is that much bigger, and depending on how the OEM packages the module it should be ok weight-wise.
Again, though, nobody has broken a 1320 as far as I know, except for whoever supplied Car & Driver and that was on purpose. So it’s possible we may see a market for an even slightly smaller pulley for stage II…I’d say we haven’t pushed it enough yet, if it hasn’t broken.
My example is pretty clear I think. I’m saying that if we pretend this rumour is true, and if it did make less WTQ than stage II, who cares if you’re picking up 135 WHP or so.
The kit will make more torque. The 1740 is bigger for sure, but very efficient. People are just spreading silly rumours.
Well maybe I was too soon to praise APR marketing since he seems to have abandoned our platform and I have to wade through your turf on the RS4 side to get updates about the blower. I hope your rumour is wrong too.
i personally think that this a device that wont benefit anyone except apr
we already have ways to datalog, we already have ways to read/clear a cel and there are already ways to switch the tune via the stalk.
they should use this to enable a flash of the software and allow the stock software to be flashed back to the ecu… now i know there response is “the stock security changes all the time and if vag changes anything it would render that device useless”
well id rather take that chance becuase most likely if it renders that flashing device useless it will render anything that apr/giac etc have to tune the ecu useless as well
App is free now.
The logging capability of this app utterly destroys VCDS. Honestly I don’t know if I could bear to use VCDS again, it would make me angry knowing how much time I am wasting.
If you don’t believe me try the demo app. If the speed of the data transfer is there, the interface is so simple to use, it’s retarded.
I’ve only played with it for 3 minutes up to this point.

That’s what I was concerned about, VCDS can log a bunch of variables at a very slow sample rate if you don’t select turbo and group requests.
I like th idea of this, however, if the sample rate is just as slow, the only thing this will be useful for is quick referencing logging to see what is happening.
Stupid 400 posts before editing capabilities.
I do like the graph function, visual representation is always better for finding something that stands out in the logs that you might have missed otherwise.
Simos is far smaller than MED9 and MED17. On our current product line we have 1 engine on this platform, the 30T. On MED9 and MED17 we have EVERYTHING else, non-diesel, that we’ve written since roughly 2006 (Except mk5 2.5 na and Mk5 R32).
so does that mean this will basically be a 2.0TFSI/TSI gadget that B8 S4 and other folks shouldn’t pay much attention to?
Looks pretty neat. Nice to clear codes and stuff.
This is just the beginning. We’ll be adding android support soon. Then more features in the app. Gauges, options, coding, you name it. It’s all in development.
We dyno from 1500-7200 RPM. The Stage 3 supercharger makes more torque at every single RPM point.
Abandoned the platform? Huh?
Currently supports:
1.4 TSI MED17 both turbo and twincharger
1.8 TSI MED17 both transverse and longitudinal
2.0 T EA113 MED9 k03 and k04 versions as well as longitudinal and transverse
2.0 T EA888 Gen 1&2 MED17 with / without valve lift, trans/longitudinal, maf/maffless
2.5 TFSI TTRS MED9
3.6L VR6 MED17
4.0T MED17 S6/S7/S8/RS6/RS7
4.2L MED17 RS5
Adding more support later on. All in development.
“Abandoned” as in I’ll likely be out of the 3.0T before this or the blower comes out… Already many many O.G. B8 S4 people gone…but support for the 4.2 is thriving at this point…good for them, but it doesn’t make sense considering the size of the B8 S4 market.
Very cool, thanks for the detail update Arin. We all appreciate your time over here.
