Wonder if Wagner came up with any new features such as flow dynamics inside the unit/end tanks? I say that because it's been years since they designed the Competition EVO1/EVO2. Did Wagner just copy the previous products, but make it bigger with the EVO3, or are there refinements? Just wondering out loud.

Please post if you get new information.
All good questions.

I already see ambient and IAT deltas of 60F on hot track days with the Evo 2 comp. That’s 150F+ IAT’s on 90-100F ambient days, and is the main reason I run E30 at the track—the timing & power pull is way less with E30 than 93 and keeps power levels up, and in my logs E30 also does a little better than 100 octane in this respect.

To compare, I saw the same max ambient & IAT deltas when I was running the full Dinan Stage 4 package and FMIC. Altho, when I switched to the Wagner Evo 2, around town IAT was lower and it cools off much quicker between corners at the track.

I’ll add some logs below:

Stage 2 5.7 Race Gas with 100 octane

Stage 2H 5.7 E30 with E32
http://www.bootmod3.net/log?id=5d7a550dae729b06e29120ea

Stage 2 5.8 E30 with E34
http://www.bootmod3.net/log?id=5d7a93fcc090c677bd36877e

And for those really interested, my whole IAT, oil, coolant temp saga is here: https://f87.bimmerpost.com/forums/sh....php?t=1525790

Doing something like adding a larger turbo to get similar/more power at lower boost levels, and upgrading the HPFP to run E40-50 is all I can think of to get these temps in check without turning the thing into a race car.

Hence, my interest in real world performance of the Evo 3 comp.
