AUDI 3.0T HEAT EXCHANGER (custom)

[@opteliv8077]

Just a heads up, I'd swap those brass fittings for aluminum or plastic ones. You dont want to mix metals in a cooling system. Those brass fittings will cause the aluminum in the system to corrode over time.

@@opteliv8077 never knew that thank you!

Great write up on this buddy good explanation and results Good work👍

Interesting ive seen this described as optimized coolant loop with auxilary radiator delete . You might want to buy the velocityAP crossover coolant pipe upgrade . Are you going to install a divorce reservoir ?

Nice I have a a7 3.0t

[@wladriazanov7078]

Can you explain 1 thing. When filming the P3 gauge your tach redline changes to 4000 rpm. Whats going on there?

[@ratelimited]

which grill is that?

[@Kruk217]

I just bought a heat exchanger. Can you make a more accurate auxiliary diagram?

[@dmcbuilds1891]

That was about the most accurate picture I could find man sorry

[@samituomisto106]

Well it don´t matter how long the hot water travels before the heat exchanger. Only thing that is important is the temperature and massflow rate of the water that enters to the supercharger air coolers...

[@dmcbuilds1891]

It definitely does something because I raced a friend of mine with the same car he has a heat ex using the factory lines with a stage 1 ecu and tcu tune I had my heat ex set up with only stage 1 ecu and beat him back to back 4 times

[@1bRad007]

Hey! Love the car and vid. I think the question here is, how did your IAT’s compare to your friend’s car during those pulls when you beat him 4 times? Thanks for sharing!

[@kdale8110]

What did you do for sensor #1?

[@DavidMorisset]

Are you a mechanic and can you provide the specs for this DYI build?

[@boogeymana6]

I've looked into the mishimoto heat exchangers but didn't see anyone else running it and people told me it would be better just to buy one from merc or 034

[@dmcbuilds1891]

Those options are still good and a lot easier to install as they are meant specifically for these cars. Although i raced my friend who has the same car he has a merc hx and 034 stage 1 ecu + tcu, at the time i was only stage 1 034 and the mishimoto and i beat him back to back 4 times and we did a roll from 40 to 140 and i got about 5ish car lengths on him. I’ve also since this video made a few changes and my intake temps never go above 20 to 30 over ambient just normal driving and when I floor it, it will within 5 seconds drop to 5 above ambient

[@boogeymana6]

I'll probably end up going with a mishimoto just to be different than everyone else

[@jaycowan6526]

Hey I got one question about this when you spun the pump to point the spout towards the passenger side does that spout connect to the bottom of the heat exchanger outlet? would like to be able to talk with you on the phone if that would be possible

[@dmcbuilds1891]

The spout on top (the vertical one) is your inlet from the heat exchanger. The one the side (the horizontal one) is your outlet to the supercharger
