Any chance you will disclose the flange internal and external diameter of the filters? Are the filters exactly the same size? Thank you very much

I know that the left side of the N54 is much cooler than the right side. Would this intake have any form of heatsoak? We know its a dual cone intake but how does it reduce heatsoak?

Thanks Shiv!

il take that as sarcasm?

jjust to let you know

the air goes to the turbos and then thru the intercooler where it is cooled before it hits the intake manifold.

The truth behind the matter is that lack of restriction is far more important than "cold air ducting". Especially in intercooled turbo systems. In such a system, the only temperature that matters is that of the air as it enters the intake manifold. But this air has already been on a long journey. It originally entered the system at the air filters. Then it travelled through the turbos, through a bunch of piping, then through the intercooler, through more piping and only then to the intake manifold. With the exception of when it passed through the intercooler, the air picked up heat at every stop. The largest heat gain occurred in the turbo during the compression stage. Here, air temps can easily rise by 150 deg F. A whole lot more than the 10-30 deg F gained from drawing air from under the hood (and not through a cold air box.)

With the vast majority of heat generated in the compression stage, it makes sense to address this stage and see what we can do to cool things down. First of all, we can actually reduce the amount of compression. And yes, we can do this without reducing boost pressure simply by eliminating the negative pressure (vacuum) at the turbocharger inlet. This reduces the pressure ratio which makes the turbo spin slower and generates less heat. And not only is there less heat generated through the reduction in compressor RPM, the amount of exhaust backpressure is also reduced. Add both effects together and you get a car that makes more power with less stress on the turbo. In fact, at 14-15psi of boost, our Dual Intake system offers a 15-25whp advantage over the stock cold air ducted airbox. And not only that, intake temps at the intake manifold is measurably cooler (that's what datalogging is for!).

#4 hahaha, problem has been fixed and was K&N's fault

#1 dyno vs bms intake?



Is there a reason why you're charging $200 for a $50 dyno glory intake?

If you buy good filters, they cost 60-70 each, the ones I bought were 110 shipped (for 2), $40 for a shop to fabricate the 3" -> 2.25" connector... 10 bux for t-bolt clamps...

Sorry but your $50 claim is laughable

Last i heard the BMS intake is USD189. I dont see how USD195 is much of a difference. Unless its nitpicking.

haha $40 for 2 reducers, wow you got ripped, $10 for t bolt clamps!!!! come on!

18.99 x 2, 38.98 + 10 for reducers, find some clamps laying around = $50

Even at your HIGH calculations your saying there is a $60 profit margin, He even said they aren't K&N so the cost of the filter is less.

Good K&N filters cost more than your shitty ebay find. You buy good ones you pay upwards of 120 total for the filters.

If you want you can just do this DIY style for less (see: not much less). But for people who don't want to deal with the hassle, buying it from Vishnu is a perfectly fine choice.
