My apples and oranges comment is in reference to comparing one intake with the airbox to another system w/o the airbox. It also refers to my comment that if you remove the airbox any of the systems can use a larger filter so that would be a necessary component to a valid comparison. As an added point, an LTR is not a Raptor 700, so that'd be apples to oranges, too, for that matter (once again, I'm not claiming that your concept isn't valid). I don't know what it is that you're disagreeing with since I'm only pointing out the factors required to make it a valid comparison, since anyone can remove their airbox and use a larger filter on any intake. I never told you not to bother to machine a demo model, I just said post a valid comparison between the intakes. The larger outside diameter of the venturi would help smooth the transition from the larger filter into the intake (which is 66mm, or 2.6 inch, not 3.25 inch), but velocity is further created at the 44mm (1.75 inch) throttle body and the ports. The volume of the entire intake decreases downstream, thereby increasing velocity. My point that anyone can fit a larger filter or remove their airbox is valid, so a comparison that didn't address that wouldn't be valid. You shouldn't take it so personally, and also re-read what my posts actually say because you're putting words in my mouth and that detracts from your credibility. I don't have anything to sell, and I never said people shouldn't remove their airbox, I simply said not many people want to. But you don't have a product to test yet, so why not wait until you have a valid comparison, but stop with the claims that the intake will be "larger" : the outside of it can be a meter diameter, the inside will still have to neck down to 2.6". That's the kind of hype that other mfr's use to pretend that the intake is actully larger when the real point of a larger filter mounting diameter is to allow room for a venturi effect as it necks down to the stock intake size (filter size itself is independent of mounting diameter but is obviously a useful way to reduce pressure drop at the filter). Another kind of hype is to claim to have a new filter "design" when in reality it's a standard fabric/wire mesh filter from an existing mfr's line. If you re-read my posts you'll see that you're putting words in my mouth and then disagreeing with things I haven't said. If you can't respond to the actual comments it doesn't make any worthwhile point to respond at all, just makes you look less credible, because most readers will find my comments valid. Build it and let us know the results, I'd be more than happy to see positive returns and I certainly haven't claimed that a different intake can't make more power, just that the others would also make more power with the other factors (larger filter, larger airbox) so any comparison needs to take that into account.
