Yeesssss! Awesome news and awesome work guys! This will be huge for consistent performance, can’t wait!FMIC Friday? Finally we have some dyno testing and data for you guys!
Here is an overall comparison from what we have gathered thus far with our 2017 Civic Si in terms of gains. We chose the dyno runs to compare because these are all 4th gear pulls with identical coolant temps and knock values (~55%). All of these pulls are untuned and using the factory Honda ECU mapping.
In other words we gained 9 hp and 3 ft/lbs tq by simply bolting on our FMIC kit in comparison to the factory intercooler setup.
- 100% Stock Civic Si Baseline: 186 hp & 215 ft/lbs tq
- 100% Stock Civic Si + Stage 1 Intake: 191 hp & 216 ft/lbs tq
- 100% Stock Civic Si + Stage 1 Intake + Catted DP/FP Combo: 207 hp & 221 ft/lbs tq
- 100% Stock Civic Si + Stage 1 Intake + Catted DP/FP Combo + FMIC Kit: 216 hp & 224 ft/lbs tq
Before anyone says it, we already know somebody is going to say, "OMG that's it?" Let's take a bigger look at this.
Here are three back-to-back (all runs within 2 minutes of each other) 4th gear dyno pulls with the stock intercooler, our Stage 1 Intake and catted downpipe/front pipe combo. As stated in an earlier thread, this car HATES 4th Gear dyno pulls from the factory. Notice the power loss from heatsoak during these back-to-back dyno pulls. This heatsoak only gets worse on hotter days or during even more extreme conditions like extended spirited driving and racing.

Here are three back-to-back (all runs within 2 minutes of each other) 4th gear pulls of the same car, but with our FMIC kit added. The car responded MUCH better to repeated abuse and testing; heatsoak was drastically reduced.

All dyno testing was performed on the same day. We saw as much as a 50 degree drop or an average of 36 degrees in post intercooler intake air temps on stock ECU mapping by simply swapping out intercooler setups. These results will only be amplified when running more boost via ECU tuning. More boost out of a tiny turbocharger = higher temps. Higher temps = increased chances of knock/detonation, thus limiting power and reliability.
- Knock Value 55%
- Coolant Temp: 199 F Start / 218 F End
- IAT Pre IC: 105 F Start / 99 F End
- IAT Post IC: 96 F Start / 106 F End
Though the power gains may seem minimal on a stock or near stock car running factory boost levels, gains become much greater when turning the boost up and pushing things to the max. Aftermarket intercoolers are intended to reduce post intercooler intake air temps as much as possible to make the engine and forced induction system as efficient as possible, thus drastically improving engine/component longevity. We expect our Cobra CAI system to compliment this FMIC quite well in an effort to reduce intake air temps even more!
