Intercooler Upgrade and Car Feels Slower
Hey I shoehorned in the Wagner Knockoff Intercooler into a 2010 and the car just feels a little less zippy to me. Slightly less butt dyno feel and less quick throttle response to throw the car around.
Anyone else have have a similar experience? I’m wondering if the increased volume of air with the larger intercooler causes a little lag? I want to eventually tune the car so started with the intercooler but otherwise everything else is stock. Based on what I’ve read I’m surprised to have the car feel slower. Potentially possibly my imagination though.
I dont hear heat or feel any leaks around the intercooler connections and no error codes.
Thoughts? Thanks!

What you are sensing is a Loss of Torque.
Look, both the size/volume and airflow of an Air Box intake system AND an Intercooler will directly effect Boost.....One needs to find a balance between pressures. If you install an intercooler with the volume of grand canyon expecting additional power from the added cooling you may be in for a suprise....
For example. While one would think an Alta intake is best for an R53, its not even while pushing 18lbs of boost and 210 hp. Pressure losses from too much air flow in the Alta will actually reduce torque. Remember, Hp sells cars, Torque wins races.
The same principal can be applied to an intercooler....The volume ( area inside the intercooler ) will directly effect Torque numbers....MINI finds that balanced based upon the HP supplied by the factory and wedging/aligning it based upon bumper support/grille design. So unless your running 30lbs of boost, and most are not. It is doubtful increasing the volume of an intercooler over stock will do very much for the Torque numbers.

I did some datalogging before and after installing my FMIC and didn't see any difference in performance as measured by time from 2000 rpm to redline in 3rd gear, over the same stretch of road. IATs were a lot lower afterwards of course.
Theoretically the increased volume in the intercooler will cause a bit of lag because it will take longer for the turbo to build pressure. But (butt?) I couldn't feel it or measure it.

Thanks for the input guys. I’ve gotten a few more days to drive the car around and I don’t think it’s my imagination anymore. Up to about 3000 rpm it just feels a little mushy, just not a quick snappy response like before. After about 3000ish it feels like it is still pulling similarly hard, but that’s not when I feel like those little snappy throttle responses (torque?) which I enjoy immensely!
After digging around the the forums I did find a couple people saying the same thing. I’m surprised though it isn’t more widely discussed.
I guess I am going to go back to stock until I get a tune some day.

The turbo muffler and noisemaker are still in place. So that’s a couple other things I could do to minimize air volume but I am doubting it would make too much of a difference.
Another thing, I think the volume of the Wagner is larger than the forge. Perhaps the forge knock off would have less of an effect and a better idea. The Wagner doesn’t really fit so great either. (It looks really nicely constructed though)

I've experienced the same when I did the upgraded intercooler. Mine is also an ebay version of some sort, claiming it the same design as the M7 one. Anyways, after I drive it like that a while with torque loss, I then deleted the silencer between the turbo and the intercooler. I deleted the noise maker between the intercooler and the throttle port. Lastly, I upgraded the BOV spring and changed it out to the Alta BOV housing. Altogether, the car felt strong again, even strong after 5k rpms. This went on for a while until I put a catless downpipe and it felt much peppier, too. Now I'm just waiting to do a stage 2 tune and a JMTC S42 turbo upgrade, but I gotta do this without my wife noticing, so... till then.

Ok great thanks for the info. Those three things should be easy cheap upgrades. Did you happen to notice which of the 3 made the biggest difference? I’ll give it a go. I’m in the same wife boat as well. Tough to justify a tune for the $$. Expensive computer code. I’m also a bit concerned about wear and tear damage with a stage 2. Don’t want to spend $600 to break the car. Wife will like that even less. Anyways thanks again.
