FMIC Power Loss

[kart3l]

Can anyone please point me to dyno charts or any other graphs to display power loss due to stock intercooler's inefficiency? High IAT-2 temperatures pulling the timing, thus resulting in power loss...

I am really happy at the fact that we have smart consumers on this site. I am a lurker mainly, but I noticed JLT's efforts in justifying their CAI as well as Mishimoto's development of the intercoolers. Sorry if I am missing out any other vendors, but your average consumer notices these efforts.

I also should not mention the copying of Airaid's CAI. Hard to trust a vendor that does this...

I also purchased Magnaflow's street series cat-back exhaust "Proven to make power", but yet to see any proof this. I e-mailed them multiple times, and still no result. We need more vendors to provide proof of what they are selling... Big applaud to JLT for dynoing their CAI on the same dyno run...

With that said, I am waiting for the Ford Racing tune, as well as CAI, and a FMIC.

I believe I will do the CAI last, because the general consensus is the FMIC's inefficiency, but I wanted to see graphs for proof.

High charge air temps result in reduced timing and reduced timing results in power loss.

Here are two logs, first one is a stock intercooler car and the second is a car equipped with our intercooler. Take a look at the timing curve versus the charge air temp. You will see that the first one comes up in timing then gradually tapers off, peak timing on this graph was before 130° Charge Air Temp. The second graph you will see timing goes up and up and up.

Both cars are on E30 and have the same modifications besides intercooler.

As you can see I'm able to run much more timing on the second car because of the significantly lower charge air temps. There is easily a 40whp difference between these cars because of timing alone.

That would certainly explain why my car feels so slow after doing one or two hard pulls.

yep, sounds like the intercooler is quite a vital piece to get to make and sustain power

Absolutely!

As I said before Ford looked for the crapiest intercooler they could find for these cars.
