Audi RS4 Upgrade Intercooler Kit from Wagner Tuning

[Nige_RS4]

ER Smics can be installed on the RS without any issues

Err, no they can't, the pipe diameter is different between the S4 & RS4 - we've discussed this before??

Looks interesting. So these are actually bigger in volume than the ones from rs4intercoolers.co.uk.

I am also looking forward to see the measurements...

all measurements are posted in the same thread on here http://audisrs.com/about1175.html

Unbelievable! In every forum sell you this intercooler

Sounds good, though I would be interested in seeing IAT data from the same car running stiock SMIC's and then your SMIC's, run under similar conditions.

Hi Jarv

We will do that comparison in the next days.
But to achieve the (as you wrote) run under similar conditions we will run both kind of intercoolers similar in the same car. One stock SMIC and one from Wagner-Tuning.
We have the equipment to log 4 supersensitive temperature sensors (sensordiameter < 0.5mm!). One of them will be placed before and the other after the SMIC. Only on that way you can be sure to have the similiar conditions. The measurements will be postet here.

I guess that would be on a rolling road, though as we know, side mounts don't perform at all well on the rollers, but I guess at least conditions would be the same for both.

The test will be made on street with an outside temperature of at least 25 degrees celsius (77 degrees fahrenheit). The testcar is an Audi RS4-B5 with turbochargers from the RS6 with some other nice stuff. The turboboost has a peak of about 1.8 bar (26psi) falling down to 1.5 bar (22psi). That car has a measured performance (on Sportec-Dyno!) of about 541hp and a maximum torque of about 745Nm (550 ft-lb). Measured with oem-SMIC's.

Hello Pascal, should i know you?

by the Way Introducing and Selling are two different things.
I think People should know whats arround on the Market. At the End, the Customer can chose by himself what his Options are...

Thanks for your Understanding.

pascal...you are a poor boy !
every post from you is to destroy the thread from someone !
it`s so boringly !!!!

go home to your painful and copied board, there you can pitch you and your friend !
nobody interest your opinions....buy and own an rs audi, and then you can build your own position...


@ Lupo911

very nice and big intercoolers ! i think the best product on the market, currently !!!
i had viewed them in real and they are very good !!!
the following tests will demonstrate it !

Hi Martin,

Thanks for confirming that. Look forward to seeing some results. I'm getting slightly confused (not difficult) about the connection between you and Lupo. Do you both work for Wagner?

Hi Mike

Lupo is from "Wagner-Tuning" (Germany). I have my own company "RS-Werkstatt GmbH" (Switzerland). But we worked together to develop this SMIC-kit for the RS4-B5.

Hi Martin,

Thanks for clarifying that, look forward to seeing the comparisons.

OK, some News...
I just got the Informations from our Flow Test. We do have a 40% incrase of Flow compare to the Stock RS4 Intercooler.

[Lupo911]

With 40% Incrase i mean "40% less pressure drop". Does this sounds better?

[flashyg]

what does that mean exactly Lupo911, please explain

You put in 2 bar and get what?

[rs-werkstatt]

what does that mean exactly

"pressure drop" or "pressure loss" are two terms to measure the flow resistance of the intercoolers.
The higher the pressure drop is, the more pressure the compressor has to workout and the higher the temperature is.

My english isn't so good to explain that in my own words.

Here a short explanation, which I found with google:

The pressure drop across the intercooler should be as LOW as possible.

Example: At high boost levels the stock intercooler has a pressure drop of 3psi - 4psi across the core. The pressure at the compressor outlet will have to be 23psi - 24psi for the boost at the intake manifold to equal 20psi - 21psi. (This higher boost level heats the air up EVEN MORE, thus increasing the heat load.)

A hi-performance, hi-efficiency intercooler usually has a pressure drop of .75psi - 1.5psi. The boost pressure at the turbo can be 2-3psi lower yet effectively provide the same 20psi - 21psi boost pressure at the intake manifold.

The measured 40% gain in pressure drop against the oem intercooler were measured on static method. Dynamic (with the effect of cooling the intake air) the pressure drop will be much better. But the static method is better to compare intercooler coors about pressure drop.

Not wishing to be rude (or ignorant), but can someone summarise all the technobabble down into a sentence or two, illustrating the net gains for stock\tuned cars?

i.e does it increase power, torque, lower something else, increase something else?
