Hey bro love your channel found it a few weeks ago. I have a 2013 A6 3.0T also and the same color. I have a stage 2+ tune. I don't really run it hard but looking to get a heat exchanger and x-pipe soon . Thx for the videos!!!!
Your pump comes on so long as you are above around 2000-2200 RPM, IIRC. One of the 3 wires going to the pump is the control wire for the car. If the wire is clipped, the pump runs all the time. Maybe rig up a "race" switch so that it runs all the time if you have plans to "engage" someone. If you can, please do a full pass and show us how fast the temps go up.
I haven't noticed any drop in performance of the condensor or radiator. I've never felt the HX get hot to the touch just lukewarm. Air passes through it to the ac condensor and radiator and they perform as they should.
I have a 2014 a7 I just went 034 stage 2+ first day on it and I noticed my fans turning on mostly when I’m at a red light or stop. So I’m looking into a heat exchanger myself now. Didn’t do no crackles though just still sounds stock til that supercharger get to screaming
The fans turning on is part of the tune where it turns the fans on high and the hx pump on 100% to cool the supercharger coolant. It's activated when the cruise control stalk is in the back position. You can turn the feature off by pushing the cruise control stalk in the forward position.
@@cmidas3396oh cool thanks for the heads up. I took the car to get the tune down due to not having a battery charger so I didn’t want to risk it. Is there an option for crackles/popcorn for the 034 tunes? Also I was looking into these heat exchangers and see a new one on preorder but a slim version that’s available now. Should I just want on the full size version?
@@southjersey1000 Yes, 034motorsport has a crackle tune option and I think it comes with the tune so you'd have to select it. The slim hx is fine for stage1 stock pulley & stock hx coolant pump. When you go stage2 & up you want a bigger hx.
Hi. Jose recommends you upgrade your pump fuse to 20Amps when installing the CWA 150… did u have to change yours? do you have any idea where the specific fuse is located ?
Yes, I changed the fuse to 25amps in the last video when I installed the ethanol sensor. You can see the location in that video but you need to verify the location of the pump fuse for your specific year because it might be in a different location.
Great vids as always. I'm planning on installing a HX and the CWA150. Any chance you know where I can find the harness for the pump? It's $250 w/tax and shipping from tecomotive, it just doesnt have the audi harness
Love your channel just found you tonight, planning my build, doing timing chains, test pipes and engine mounts rn, have you seen merc racing is releasing an updated 3.0 heat exchanger? Opinion on it vs the 4.0T X?Cheers
Haven't seen anything about another updated 3.0T heatexchanger besides the latest version that I have. I think to get the best out of the bigger heatexchangers more coolant needs to circulate. There are people that have done things like bigger 3/4" hose and bigger pumps plus coolant ports to get better flow through the intercoolers.
There was a good amount of space actually. Originally I was supposed to run the bigger 4.0T cooler but Merc is out of them. I may change it later after he gets more in.
It's 7.09578.00.0. I got it from the Santa Monica dealership but I think it was the last one for the online price but if you do a google web search you should find others.
@cmidas3396 I am looking to move forward with this s5 , but I am big on preventative maintenance, so very curious about the cooling options, the best and right way
@ronkirkham3410 You only need this if you are going to go with a dual supercharger pulley which will spin it faster to make more boost which in turn creates more heat. To deal witb that you can upgrade you heat exchanger to a bigger one for more cooling capacity and a higher flowing auxillary coolant pump for more flow through the bigger heat exchanger and intercoolers in the supercharger. I recommend the MercRacing heat exchanger and you can go with the CWA100 axillary coolant pump that is available at MercRacing alao.

Youre welcome. Good luck with your build

I pulled the pwm in a later video and did a run. I'm gonna get the VelocityAP intercooler ports so the system flows better.
Ever upgrade the radiator suport . Under carriage shield ?
No but I might as long as I can find one with a felt lining to absorb fluids like the factory has.
How’s this mod affecting cooling for the radiator and condenser?
I haven't noticed any drop in performance of the condensor or radiator. I've never felt the HX get hot to the touch just lukewarm. Air passes through it to the ac condensor and radiator and they perform as they should.
Did you get a code for no signal feedback from the pump? I didnt get a CEL but it did show a fault code after install.
I think you only get a code if you pull the pwm wire for it to run at 100%

@@cmidas3396appreciate the help. I’ll just do the preorder and wait it out. Since I did stage 2+, Hopefully shipping isn’t to crazy of a wait lol

You got a link to the harness. Can’t find the guy on eBay
I don't have a link but a while back he told me he's not making them anymore for the time being.
Great vids as always. I'm planning on installing a HX and the CWA150. Any chance you know where I can find the harness for the pump? It's $250 w/tax and shipping from tecomotive, it just doesnt have the audi harness
I think if you get it the pump from MercRacing it comes with a harness.
Hey, did you get any codes after installing this.
You will only get a code for the coolant pump cwa150 if you pull the pwm wire.
Are you have check engine or some problems with installing cwa150?
No engine light, no problem.
do you need this to do stage 1
No but it's recommended to upgrade the HX but you don't need the cwa150. You can also check your tuner's hardware requirements per tune stage.

how much extra space was left around the heat exchanger to get a larger one in? about to do this myself & wanted to see if you had any thoughts
There was a good amount of space actually. Originally I was supposed to run the bigger 4.0T cooler but Merc is out of them. I may change it later after he gets more in.
Did you ever upgrade your fuse for the bigger pump ?
Yes, I did it when I installed the ethanol sensor.
@@cmidas3396 do you know where the fuse is located
I can't remember exactly where it is but it's in the fuse panel under the computer under the raintray.
Hey brother - can you provide a parts number on the pump? Also, which dealer did you get your pump at?
It's 7.09578.00.0. I got it from the Santa Monica dealership but I think it was the last one for the online price but if you do a google web search you should find others.
@@cmidas3396 thank you brother! Appreciate it! Love your content bro
Great video, being serious.. can younhelp me understand what your speaking of with the pump/harness, etc
What exactly do you want to know?
@cmidas3396 I am looking to move forward with this s5 , but I am big on preventative maintenance, so very curious about the cooling options, the best and right way
Also I am not a teenager! I hate all this online, email, messaging shit, we're grown, I'd like to speak

@@cmidas3396 correct, 100% were I'm going, beyond full bolt on, this is going to be a serious project
Loving your content. Please do me a favor. Wipe down your engine bay. 😢
Yeah I just cleaned & detailed it not too long ago but it's dusty where I'm at.
I really enjoyed watching this video, please make more. You need to look into "Promo sm"!!
Thanks👍
