This is my experience after deciding to change out my fmic with an upgraded one on my IX MR. Before the fmic, I had tbe w/ cat delete, intake, boost controller, fuel pump and Dynoflash. What I am comparing is a guy I know with a supercharged Mustang that put down 360 whp on a Mustang dyno with pump gas. Everytime I have raced him he has put in race gas and advanced the timing. So, he is making quite a bit more power than the original dyno. Plus we all know Mustang dyno's read very low, so this guy is putting down some power. Every run that we've had in the past, we are dead even! If anything, he pulls a fender on me. It is such a close race. I have been wanting so badly to beat him, so I bought the fmic knowing I would need it anyway when I go big turbo. We'll I got to run the guy again, and the result..... The exact same as before. The fmic made no difference at all. The fmic is a very nice piece and is much bigger than stock, at my power level though, it just didn't do anything. I need to start saving for that big turbo kit. This is just my experience. Take it as you will, comments welcome.

 

What FMIC did you get and were you on race gas?

 

Also did you get re-tuned after your install? and did you increase your boost back to the same level as before the install?

 

I thought a bigger FMIC would have larger fins allowing more air? I too was thinking about adding an aftermarket FMIC but there is much controversy on this subject! I am going to add new cams, UICP, and then see what I get on the dyno. Eventually I will do the whole ,50 trim kit from DTM in February!

 

I didn't need to adjust the boost, even though I still turned it up a bit. I wa pushing about 22.5 lbs. This was on 93 octane which is what I am tuned for from my mail in flash. The fmic was the regular version from AMS. A very nice piece.

 

In order to make an upgraded IC worthwhile, one first has to be able to generate enough airflow and heat to render the factory IC inefficient. Those at moderate power levels who expect static power increases from a larger IC will more than likely be disappointed.

 

Ted, would you say that the level of heat generated on an open track would justify an upgraded intercooler at 330-350 WHP?

 

It's anyone's guess without real-world IAT logging, but extended on-boost situations present much greater demands for heat dissipation than do a few seconds of drag racing. In such cases, the benefits of a more efficient IC are not something likely to be revealed on a dyno.

 

About the race part, If you he is making more than 360hp mustang dyno and you are dead even then that dyno must be wrong I dont think that on top you would be even unless he ran out of gear or something.

 

I have an evo1. I upgraded to the ams evo8 standard core. I felt it was a step backwards. Had to turn boost up 2psi to get the same feel. This was at an early stage of mods with the original evo16 still on the car. I too figured i would grow into it so I left it on the car. Plus I loved the look of it. I have used sevaral evo8 cars on dsm cars because they are cheap. I have no problem making 420whp on them. Haven't pushed one higher yet but i think its good for 450-475whp.

 

I went to an SBR fmic on the stock turbo and also found no gains. Of course this is on race gas, which is the ultimate bandaid for poor intercooling, so it shouldn't be a surprise. I'm only seeing a 10 degree increase across a full quarter mile pass, so it does a great job of keeping things cool anyway, and I'm sure that is what bumped my pump gas mph up a couple.
