less air volume + less PSI reduction = not enough heat exhange per the increase of power / higher IATs = more timing pulls

So in other words we dont want to go too large nor too small with our tiny stock turbos.

Helix seems to be a good 1st candidate, or the HPF Intercooler
Thanks for clarifying.

I understand why fmic are good for the car, I was simply wondering where you came up with 90% more volume.

My understanding would be that fmic don't force more volume of air into the car, but more oxygen dense air by lowering iat.

A larger core would simply be more resistant to heat soak and be able to cool more air. Negatives would be pressure drop bc the volume is large and slows down the air velocity going from the turbos into the intake manifold.

Please correct me if I am wrong.
