Agree I think they are more and less on par. But still the price and performance seems to be better with the DO88 IC

Hmm...thought I’d seen around 20lbs for the Comp II. Either way, both are lighter than the CSF.

I’m going to do a bit more testing with my Dinan IC later this yr to see if it warrants replacement with the Evo Comp II or do88.

Trying to find the best balance between weight, pressure drop, and ambient/IAT deltas for the track.

Look at the diagrams in this link

Better from all aspects compared with Wagner IC and the price tag is better as well

This looks very interesting! Only thing I would like to know is if there's any noticeable increase in turbo lag with this one..

Fair price and good looking (and not too heavy)!

No fitment issues? No noticable increase in turbo lag?

If you go to the x-ph website and select M2 first then Intercooler, this vrsf hd ic should show up.

I had no noticeable turbo lag, but I already had a fabspeed sportcat dp installed so that may have helped.

Install of IC and Chargepipe was easier than the dp install. No fitment issues.

I won't truly know if it's worth it until the 100 degree temps roll in.

I went for a proper drive today to test my theory about lag/dull response since adding the FMIC. The car is definitely not the same, the responsiveness is greatly reduced. It was already immediately noticeable at take off around town, but then even on backroads when taking really sharp bends and dropping gears, especially very low speed to 2nd gear, getting on the power just doesn't register for what feels like at least a full second.
I replaced the charge pipe with VRSF at the same time as FMIC install, and the workshop told me that the angle they've machined the pipe at means the pipe is quite tight in placement. They needed to insulate it with rubber as it sits metal on metal against another part of car. I'm wondering if there isn't some leak occurring between these newly added components.

Question - would that result in a CEL if it was the case, or just reduced performance?

Thanks

If you look at the flow chart it looks like the do88 gives less turbo lag at least compared with Evo 2 IC.

Well, that chart is airflow at certain pressure differential. It could be that at the same dp the Wagner flows enough for the engine’s needs and there would be no difference in response/lag.

I don’t know, tho.

What brand and model FMIC did you get?

Maybe you have a boost leak? I don't think a minor or moderate boost leak would trigger a check engine light but I could be wrong.

[specka]

I have the Wagner Evo II Comp. Boost leak is definitely something I'm wanting to investigate.

Yea, the comp 2 is around 20lb cause it's tube and fin. But I was comparing it to the bar and plate Perf 2 IC, since the dot88 is bar and plate as well.

Evo 1 Performance (bar and plate) 8.8kg
Evo 2 Performance (bar and plate) 11.5kg
Evo 1 Competition (tube and fin) 6.6kg
Evo 2 Competition (tube and fin) 8.6kg

Looking at this, an intercooler and charge pipe added 8hp with stock tune. Hmm...

On a stock or lightly modded car go with a 5" intercooler

Wagner EVO I, VRSF 5" or Active Autowerke

Mike, would it be preferable with the performance over the competition or vice versa for that stock/lightly modified car?

I just saw that the competition was lighter..but maybe the weight difference could be nullified by other parameters..?

Competition is better than performance in every case, its lighter and recovers temperature faster

Hey Mike, what other fin/tube FMIC’s are out there besides the Wagner Comp?

Only Wagner offer tube and fin intercoolers

However, since the M2 is already, imo, fast enough I'm most likely to not tune or get a Stage 1.

But is it worth upgrading the fmic even if I don't tune at all? I don't track, only spirited driving when opportunities arise. I do think though that maintenance is important and I change oil and spark plugs more frequently than recommended.

So keeping the engine cool is pretty good for the longevity I think but I don't want to overdo it and rather spend money on other, more necessary maintenance.

I will give you my experience with upgrading to the Active Autowerke FMIC and intercooler to throttle body pipe (aka charge pipe). For the record, I do not have a tune, but I upgraded my stock downpipe last summer to the HJS 300 cpsi downpipe before installing the FMIC and charge pipe in December. A local specialist German shop installed all the parts.

The FMIC, charge pipe, and downpipe fit like they were an OEM part, and the technician who installed them said they were OEM or better quality.

I have not noticed any increase in lag after the installation of the Active Autowerke FMIC and charge pipe—not that there is much in stock form. Indeed, I would say the cars pulls a bit harder throughout the RPM band, and even pulls to 7000 RPM with a bit more urgency. In terms of performance gains, I would say I feel more from the FMIC and charge pipe swap then I did from the downpipe. In sum, I have not felt any negative effects from changing out the FMIC and charge pipe to the Active Autowerke parts.

Fundamentally, I made the move to the Active Autowerke FMIC and charge pipe because I live in Florida and wanted a more efficient intercooler to deal with the nearly year-around heat and humidity. I am very happy with my decision and would do it again.

Hope this helps.

Personally, *I* would not upgrade an intercooler if I'm keeping my car stock. No way.

Why not?

1) The car is designed for that power level, for street, with that IC. And so what if it cuts a little power ??

2) OP is in sweden (cold)...I've had absolutely no noticeable street issues with stock IC in Dallas heat

3) Once u start messing with IC, you MAY have warranty issues, you MAY have quality issues, etc. IS it worth it? It wouldn't be for me.

This is relevant input, its rarely very hot here for more than a month or two. And I'm not even sure that what I call "very hot" counts as very hot for the car.

Last summer was unusually warm where we reached up to 30 degrees celcius (about 85 deg fahrenheit) for almost a week. Otherwise we are happy to see even 25C/77F at all during summer. Rest of the year below 20C/68F for sure, at least where I roam.

And I rarely push the car to the max but I'm still battling inside because keeping the temps lower in the long run would probably benefit the health of the engine/turbos..

So many decisions to make, so little time...
