Very different engine.
I was going to ask if it actually did anything performance wise. I saw a bunch of different dyno graphs but to be honest the results didn't make sense to me. Like it seemed to have a larger power differential on the stock map than it did on a Stage 1, I would have assumed it was the opposite. I like loud intakes, but I also like how you can make good power with the K20C while appearing stock thanks to all the heat shields, etc...
Yeah honestly, I'm not really sure if it does much, and that is mostly based on stuff I read a few years ago when I bought it and the Borla catback, that basically indicated that the Bosch? ECU would compensate for most stuff done to them unless it was tuned. No idea how accurate that info is/was, but it doesn't feel any faster.....just sounds 100% better.
This right here is accurate information. I'm a mechanic and can CONFIRM this is TRUE AND ACCURATE!
This is exactly why I wouldn't change to a BOV. The recirc valve maintains the metered air, where the BOV dumps metered air and creates a rich AFR. I won't get into the debate if that is good or bad for your car, but personally I won't run any of my forced induction cars that way if they use a MAF. On my twin turbo 300ZX I could use a Haltec ECU and tune, which changes the MAF to a MAP setup (manifold pressure), but don't want to put that much money into a car that is already tuned and runs great.
Agreed on getting an intake rather than BOV, but disagree with getting the Dream/Pipercross intake. Not gonna lie, it sounds fantastic, but you are almost guaranteed to lose power with it. Per above, I would wait on the PRL HV intake which is another 2-3 months out. Should get you the sound you want while at least maintaining stock power. There was also a video where they swapped out the FL5 turbo inlet for the PRL TI one and I think that opened up the sound quite a bit. I don't think that's as big a bottleneck on the FL5 as it is the FK8 though, so gains are probably minimal.
Yep. I agree with getting the PRL HVI if your after sound.
I get your point. However why would dream automotive leave it installed on their shop car if it lost power? They're a very notable performance shop in the UK. With all the exceptional air flow this new platform has I really don't think it will lose power. Maybe not make power. I think it will be negligible. Only way to know for sure is to put it on a dyno before and after which I plan on doing.
The problem isn't the filter, it's the fact that it is no longer a sealed system pulling cool air from the grille. So on a dyno with the hood popped, I am sure it would do fine, maybe even on the track with constant air flow it will be fine. But sitting at stop lights and driving normally, you likely will have an increase in IATs that would more than offset any increase in flow you are seeing from the filter. I think they even admit as much during the install video.
Just to jump in here, the PRL HVI is great and super easy to install / feels like it maybe gave a little bump in performance. But I do want to say that there really is not a noticeable difference in sound, in my opinion with the PRL HVI, at least with the 6-speed MT ASPEC-Tech Integra.
