Q for MSP FMIC owners

[Heathen23]

Heathen23 - the reason why the differences in power figures gets larger and larger is when air becomes heated, it requires less space. It also has less "potential energy" (b/c of less O2 molecules per given volume). Thus when an I/C core is heat soaked, every consecuative run will be lower then the previous until you hit a "saturation point" at which the #'s don't get any lower. The point at which the I/C hits the saturation point is the real measure of power difference. That's the reason why we tested our own set-up till it hit saturation.

Yeah, I get that. But that is not a gain over stock, that is a gain over the decrease using the stock components over time in heat. That would explain it much better. Unlike (let's say an exhaust) that yields 20hp which is simply a gain over stock numbers, a fmic only yields an improved number better than the stocks decrease over several runs.

To clarify-

Imaginary numbers for simpllicity :

Stock car: 200hp
Add exhaust: 220hp

Stock car: 200hp
Add FMIC: 200hp

Stock car after 30 mins of driving in high temps: 180hp
FMIC car after 30 mins of driving in high temps: 200hp

Makes sense no?

If that is a not an accurate interpretation of what you are telling me please let me know. I realize there are minimal gains from going from the stock plastic to a more ridgid metal but that doesn't yield the dyno numbers we are seeing from various kits.

Sorry for the long and somewhat insane posts!

so like ur kinda saying is FMIC worth it cuz of minimal gains until the stock IC gets heatsoaked? That it is not going much until 'it gets hot in thurrr' ?

Nah, it's worth it depending upon your goals. That's not the discussion for me actually. I just thought it was weird that a typical support mod (fmic) for power was dynoing large gains. It's ideal for consistency no doubt, but the gains over stock aren't as plain as say adding a boost controller, a larger turbo, or an open exhaust.
