Just A Quick Thought About Increases Of Lag

[GTAAAH]

Just thinking that most of the people reporting an decrease of throttle response when mounting large FMIC's have r33's. r33's come with standard BOV's right? And they clear excess air in between the turbo and the inlet manifold right? But on cars without a BOV this space would always have backed up air, on supply, and i was thinking that a bigger intercooler size therefore wouldnt make much difference at all. Would take very little air to fill all the spaces up again. Does that work? Just thinking at work, bored out of my mind.

The blow off valve exhauts the build up to stop the turbo reversing spin, some atmo's will do that on larger coolers (mine did) as it shuts before the whole build up gets out.

You could add a one way flap, but it would be heavy duty and noisy I think, or maybe not work well at all, just a thought.

Ahh so they only expell part of the build up your saying, so that theres sufficient air left to help after the intake re-opens but theres not so much that it cramps and tries to get back out via the compressor. Hmm would still make sense then that no BOV would decrease the lag inherent in having a large cooler.. perhaps to a lesser degree tho

Well yes but if you dont accelerate the turbo flutters back and forth, untill that build up disapates.

My stock one doesnt do this with the bigger FMIC.
