If we stood at the drawing table together Arin and said 'Here we have an rs4 and rs5 that are capable of flowing 750 cfm all motor with tune and full exhaust. What supercharger should we add to it to make a meaningful gain for a five figure sum of money
Supercharger a) which maxes out at 850 cfm
Supercharger b) which maxes out at 1200+ cfm
I think we would say… Supercharger b will be a great choice.
Not to say that pes has a fucking clue what they’re doing but if we just look at choosing a blower, I think you’d have a tough time finding people voting for the tvsr1320 in this case.
P. S. I mentioned this Whipple change in the rs4 supercharger argument. A few of us have discussed it in there.
A whipple, or any twin screw for that matter will walk all over a TVS given the same size. And AIT’s will be lower given the same amount of boost
Eaton needs to build bigger superchargers.

Keep in mind Spinner’s assuming a TVS1900 for the APR RS5 SC. He has no data to support this claim.
[quote=“Arin,post:4,topic:4111”]
SO give us some data…how about just one number 
How is PieceofExpensiveShit still in business… They were melting engines with the m90…imagine how many engines they will fuck with this larger charger!
PES cant tune for shit and their kits are poorly engineered. Streamline industries did a PES RS4 a few years back and the kit came in one big box all jumbled up with NO instructions…finally once they assembled it of course the car didnt run because of the fail tune.
If i were APR i would sit back and /popcorn
Yea I wouldn’t worry if I was them… although PES seems to have decent success in the UK based on that forum. Based on the fact that more than their spokesperson is using their product lol.
Arin you are so unbelievably pathetic and boring its comical, what’s the matter Arin you don’t like a little competition? I like how straight forward pes have been with there blower selection. Why can’t apr do the same? Is it because your trying different blowers until you find one you can successfully tune on your own, without an outsiders help? I say qudos to pes for being bold with this one and I for one hope that they succeed with this. It only brings more options to the 4.2 platform.
I don’t see how Arin is pathetic nor boring for calling out spinner?
Spinner made a bogus claim that this pes kit is better than the Apr kit when he knows nothing about the apr kit, and only knows what blower the pes guys hope to use (take note… Pes don’t have this fitted and running.
We have seen supercharger companies advertise a bigger blower for their kit like this before and have seen them unable to get it to fit properly (vf engineering for example with the m112) only to ditch the blower for something entirely different.
If pes fits it and runs a great quarter mile time (or dyno sheet for the gullible) everyone will pay attention and give it a look. Until then this is all talk.
Thank you Sakimano, I think you echoed what I would say in response.

There’s a very good reason why we aren’t doing the same. Anyone, and I mean anyone, can start the speculation train right now, and they will not even come close to having a correct answer. I’m fairly confident of that. When I do make an announcement, it will all be clear why I kept my mouth shut for so long.

Well, scratch what I said above. You nailed it. We’re trying out best to figure out the a blower we can actually tune. We’ve gone through so many! Maybe it’s time to try a whipple… Strapping one of those on should fix everything, right?
Just an FYI, we’re not bolting a supercharger to our manifold like everyone else. It’s integrated like the OEM units. It’s already cast, and it’s already here and ready to go. We’re designing all of the other parts associated with the kit, and developing software. Here’s an example of our S4 design:

Hmm, well after much though, I don’t think there’s any harm showing it off. I’ve held off for a long time, but I don’t really see any reason to continue holding off any longer.
It’s a 1 piece manifold / charger design (like the OEM S4).
I’m not ready to share any other information at this time.
Enjoy.

Shoulda been a whipple
Yup, I know, I know… we probably shoulda kept undersized cooling too. ; )
When can I buy one for the S4??? 
pretty cooll looking with the black offset by the shiny bits. Maybe a bit tough for passing smog inspection though in california or Ontario where they do visual.
The twin throttle bodies look cool.
Here’s a question…what size are the throttle bodies on the RS5? and the one on the B8 S4? The one I’ve seen on the S4 is quite small compared to the all motor cars. Not as big an issue with a blower in the manifold, but just wondering.
Too small of a throttle body will definitely be a big restriction. You want both ends to be able to flow the same amount at peak. That’s what people port the superchargers on cobras and GTP’s, to get the inlet of the s/c to flow the same as the outlet. And even then the stock throttle body is a restriction until you upgrade to something big. An inlet restriction is more detrimental than a restriction on the outlet side in most cases.
Saki, S4 tb is 70mm…
Joe, agreed!

Hmm, maybe someone can hack carbon fiber plates to put over the logo. Then it would look pretty stock. ; )
Our Swiss dealer got DTC approval on the old unit and they are really strict.
On the RS5 it shouldn’t be a problem, especially since there use a dual TB setup. On the S4, we’ll be going larger, and we already have that covered.
But will the rest of the intake tract flow enough on the rs5? If its anything like the s4, there is not much room between the firewall and the motor so hopefully the inlet of the blower isn’t undersized. We demand more pics. Or CAD drawings
lol
Poor Arin opening a can of worms.
Blower looks nice. Can you confirm that Jwoww is going to tune this bad boy?
