I think BOV's sound cool!
WOW … my BoV is getting some derision!!
So, basically, despite the fact that I have a well built, competitive Time Attack car that is actually used as such I am a RICER (which in the context of this discussion is a negative term) because I have a VTA system.
Interesting.
Do you have the same opinion on people who fit 19x10.5 + 12 wheels to their EVO 10s? How about an AMS wide mouth down pipe, is that a fitting mod? Perhaps there is no technical benefit in having twin exhausts?
Let me guess, I am a RICER because I have installed a HKS ECU …. or even because I have a fuel surge system……
Now I know why you lot get your own special ECU
Normally, with a VTA blow-off valve, that metered air is measured at the MAF, once it is spit out via VTA, the car runs retarded rich expecting that air to be in the system.
How did you get around this? Why did you purposely do this? (not being condescending, honestly asking).
To me a ricer is someone that adds something to their car that doesn't have a performance benefit, often causing a negative performance impact (ex: 23442lb wings on civics).

They wont help my case; I was more interested in wowing the crowd with my RICE flame kit, than posting a good time!
You can see the car and the flame kit here!

I am somewhere on that balance line between these two... approaches.
Even though my car will be tuned to run at boost a bit higher than 26... I'm going to use my EBC to tone it back. plus my aluminum piping on the intake and my Forge RS DV are going to make a bit more noise. This makes me happy, and that's good enough for me.
There is empirical evidence that without a custom tune to account for speed density a VTA BOV will at best will be neutral. MAF controlled cars just can't benefit. from it as well as a Speed Density driven car.
So in other words. as we have all said many times before. it's your car, mod it how you want. I personally still get a little chubby when I hear a BOV pop off and it's backed by a fast looking car. Evo X, STI, Speed3, etc...
But to be fair, at the same time I swapped my SSS trunk/spoiler out for an MR trunk w/ lip. makes the car look classier to me. but I am obviously a fan of the wingless look. I do know that I gave up a small amount of down force by swapping it out. but it looks better to me. Is this rice because it's not making my car faster, but technically, a bit slower? Of course not.
If you have the time, patience, and funding to pull a VTA system. good for you man. throw up a youtube link because I want to see/hear that beast.

Great Post!!!http://www.youtube.com/watch?v=mkRQF...eature=related
We're currently testing a custom turbo, but it is looking good so far!

If you want a more detailed answer I can ask the cars engineer to write one.....
Why did I go VTA ..... I think there are 4 pages on this, but the short answer is because I like it and there is no technical reason why i should not do it...... is it a benefit to go VTA on my setup ..... I'll have to get back to you on that one!

This weekend, somebody drove my car around the track and I thought to myself .... "that thing sounds evil" ..... so I shot a little video and posted it on here saying that "I think BOV's (sic) sound cool!
Thats about it..... nothing more sinister than that!

I actually put the F-Con in about 30,000km after the BOV, it is possible (although I don't know the details) to run a VTA setup on the stock ECU (well the non-USDM one anyway).
I only changed to the F-Con and Valcon when we wanted to maximize the potential of the stock turbo, and get ready for more extreme upgrades. It was a case of forward planning The F-Con gave us a lot more torque and improved the power profile, but we had to build a base map from scratch which was a lot of work, even with the help of HKS. Currently we are working on better integration between the EVC and the F-Con.
One thing we did learn from the F-Con was that if you exceed 1.1G in a long sweeping corner, you will starve the engine of fuel. The stock ECU does not detect this. Thats why the car is shooting flames in the video, the F-Con noticed the fuel pressure drop and cut the ignition. That's why I have the surge tank now. So in that respect, the F-Con was money well spent!

You can see the BOV in question @ 11 seconds ..... although I know this might send some of you over the edge!
