BOV after intercooler, autocross
I have an FMII kit that places the BOV after the intercooler. Anybody have experience with moving it before the intercooler want to weight in on whether it was worth the effort?

I highly doubt it will matter. Ive had it in both locations and its just personal preference.

To elaborate, at least at my typical autocrosses, the BOV cycles dozens of times per run. My thinking is that each time it blows off, that was heat dumped into the intercooler before going out to atmosphere that could have just been vented to atmosphere without heating the intercooler first. At autocross speeds, there isn't a ton of flow over the intercooler to begin with, so it needs all the help it can get. I'm just not sure if it really makes much difference or not. Anyone else want to weight in/agree/disagree? |

So why would you want to put it before the IC... |

Well, there isn't much more I'm doing on the driver skill front, so this is what I have left to get faster, obsess about splitting hairs :D

How about going on a diet?
But actually, I've already gotten right on that. I've lost 18 pounds net so far since last fall, including re-losing the weight I gained when my daughter had her heart surgery and complications afterwards. It has been about a pound per week lost, which is, I'd argue, a good rate for being sure to keep it off. |
the short answer:
buy an EFR* *just don't expect it to last |

okay i see what you're saying. but your IC is close to 90% efficient and it's not going to heatsoak...so it's really mute.

You mean for the built in recirculating valve? that seems a big excessive. I'm pretty sure it would exceed what I paid for the whole car too.

So I've thought a bit more about this, and I think I'd rather have the BOV on the cool side of the intercooler to keep the flow direction constant, rather than on the hot side to keep the heat out of the intercooler.
