Why don’t you buy one and modify it to fit - I think the M2 has extra bracing, which is why they may not be ‘compatible’

Otherwise, the ATM is a superior performer on the track, and barely gives up anything in throttle response. There is also the VRSF large core Intercooler a.
Have you considered upgrading the Diverter valve?

The ATM is in the same boat, as it’ll require modification for the M2. And, a 7-11F on track IAT improvement actually isn’t that much when running an E30-40 tune bc the ethanol drastically improves timing and power pull with higher IAT.

Now, if I could get the Evo 3 to work, it’ll give a 20-25F improvement over the Evo 2 which would be noticeable, and apparently similar throttle response as the Evo 2. Tho, it weighs 6lbs more than the ATM and 10lbs over the Evo 2.

Maybe I should order and modify it. Just sucks to pay that much and still have to rig something up. If it’s just remove the bracing, that’s easy, but I can’t get a confirmation on that.

Sorry for all the M2 talk over here guys, I thought the Evo 3 was a go for me and wanted to mention it over here.

What about VRSF?

Maybe they have something and I should look into it. I just know those big bar/plate ICs are damn heavy and not ideal for road track setups.

I’ll take a look.

That’s just not true. Again, the ATM outperformed the Wagner by 10 degrees despite being a bar and plate, and despite then bring the same exact size - They are both are 6” cores.

You’re all caught up with the marketing hype, but it doesn’t seem to mean anything in the real world.

Not sure what you’re referring to that you think I said isn’t true.

As I mentioned, a 10F difference isn’t going to make much of an impact for guys running Emixes on track. I wouldn’t trade to a 5lb heavier IC with worse throttle response in town to gain what would only be a few hp on an Emix tune on track.

To get a 20F+ difference over the Evo 2 we’re talking about needing a massive IC, all of which are going to be 30lbs+. I need to see if any of the massive bar/plate IC’s have that kind of performance gain without making lag even worse.

Apparently the Evo 3 achieves all these things from Wagner’s data, but I have to figure out what about it doesn’t fit.

I installed the Active Autowerke IC and currently run BM3 stage 1 and there is definitely more turbo lag of idle. I got such a great deal on the IC from XPH I couldn't pass it up as I do not track or race my car. I'm hoping that when I switch to stage II I'll get a little more boost down low to make up for the lag. Just waiting for the weather to improve in the northeast before going stage II.

Have you logged or otherwise confirmed no boost leak? I know when i first installed VRSF IC+CP and flashed stage 1 i was really disappointed. The car didnt pull hard off the line or "surge" with torque when flooring it from idle. Turned out i had a boost leak. After if fixed all of that, throttle response/lag was dramatically improved and pretty much no different than stock.

I have not done this as I feel that the car really explodes at 2k and above especially with the addition of the DP.

Let's see a 1-2-3-4 log from a dig (no launch, WOT from idle) and a 4th gear log from 2000 - 6500.

Can you describe or quantify the amount of increased lag?
Is it very noticable or bothersome?

IMO the lag increase form adding a 5.5'' stepped IC such as the VRSF, AA, etc, is nearly imperceptible compared to stock. I think he might be exaggerating (read: overly sensitive) and/or have an issue like a boost leak. I guess what i am saying is that you should not let fears of increased lag prevent you from making this important upgrade.

To clarify, I notice a bit of lag off idle until 1800-2K. I feel it is slightly more noticeable especially in comfort mode than sport. Most single turbo cars have some lag down low and I was warned about this when upgrading the IC to a large one than stock. I would not let it deter you from upgrading however. I'm hoping when I flash stage II it will not be an issue.

a bigger intercooler might have a slightly higher pressure air drop (the better the intercooler design the smaller the difference is going to be), but it will provide much better cooling allowing the car to make more HP

Mike,

I am in the same position as johnung who posted earlier. Trying to avoid turbo lag and pressure drop. Looking to go FBO with BM3 Stage 2 93 octane. Mostly daily city driving with some spirited weekend driving. I don’t track or race the car. Only difference is I am based in Phoenix, AZ with a much warmer climate than NJ.

I am wondering if the Wagner EVO II Comp would be the best option for optimal cooling for my climate while still avoiding turbo lag/pressure drop? Or would I be better off with the EVO I Comp? Any reason to choose one over the other for my application?

If you’re stage 2 FBO - the Evo 1 is too small, and you should be looking at 6” cores like the Evo 2.

With that said, if you track the car, the Evo 2 is just too small to provide adequate cooling compared to other brands. If you don’t, it’s a solid choice.

Most brands do introduce much if any lag into the system, but I have heard good things about the Wagner overall in that department though.

Wagner EVO II Comp is a very solid option. It provides the perfect balance between keeping temp a check and no turbo lag. Its also light and has a fast temp recovery after a pull

AmuroRay & Mike,

Thanks for your guidance & expertise on this subject! Sounds like EVO II Comp it is.

+1 for VRSF 5. I'm running BM3 stage 2 with catless and no lag at all...

Yeah man I love mine. For daily use and just over 300 bucks I'm happy!
