Yeah but you totally missed the part about the timing.The IAT is in the MAF sensor and underhood temps are way above ambient temps.Here is food for thought:You have two cars,both have the same TMIC but one has a stock box and has intake temps of 115° and the car with a short ram has intake temps of 150°.Do you think if you measure the temps after the TMIC that they are going to be the same or there will be a 35° difference in temps.....

I see your point, at least in theory. I haven't seen dyno sheets to take theory into real life. Not disagreeing with you, just haven't seen it in practice.

Also too,when you launch your IC is really not being very effective at cooling at that point because your not generating enough airflow over it.Thats why radiators have fans.When cars stop moving and no airflow is going over/through them then they are not being an effective heatsink.

Ya know, I was going to make an argument, but I decided against it at the last second. It's pointless. Slipping the clutch agressively is a lot better than clutch dumping, so i don't see whats wrong with the advice, what would you rather replace, the gears and/or tranny or just a clutch?

launch control is a beautiful thing..i had it set to 4500k and would come off the clutch just right n im off...wudnt recommend launching without it... i actually waited 5 months untill i got it before i took the wrx to the track cause i didnt want to launch without it..too much thinking and balancing between throttle and clutch..and you dont built that much boost
