In theory, many things seem like they would work better, especially when they look like a million bucks. In reality, it's a crapshoot more often than not. The proof of the pudding is in before/after dyno numbers with A/F logging to determine what (if anything) is really happening.

Without that, it's pure speculation.

 

Exactly...it's the exact same design - slighter larger intake, and no separator. I would surmise that counts up to a .5% improvement in overall HP.

 

I'd even take it a step further than that, because I don't believe you can really test the effectiveness of a ram intake on a dyno. The only way to really test it would be on the road with AFR logging. Anytime you change the intake configuration you need to log AFRs and if you really do end up with a more efficient intake, then I can pretty much gaurantee that you will have to retune your car to accomodate the new airflow.

Also, if you really look at how the stock piece is designed, I don't think the HKS piece offers much of an improvement. For example, just looking at the pic, I don't see the foam cushions on the HKS piece, which will allow more air to bypass it.

that was my point...exact same design as the stock intake, but with more airflow...the stock intake is a good piece and is designed properly...the way an intake should be designed...but it lacks airflow...hense why this intake is better IMO

and your .5% HP surmise is based on what?

 

I realize that not much can be derived from one simple picture...i would like to have the part in hand and do some testing on it...which is why my original post said

i guess ill have to be the one to test it out since no one else seems interested in its design

 

Do you have an intake volume/flow resistence comparison between the stocker and this? Just a question. Don't forget that the MAF is going to be unhappy with the change in flow.

I was kidding around 99% of the time, without the appropriate tuning for an intake they yield very little real world performance. Really, it's only the last thing to do when you've done everything else (like turbo, intake manifold, downpipe, exhaust housing etc).

Don't get me wrong, intakes can help in instances where the factory air intake system is poorly designed or inadequete. However, there are much better ways of generating horsepower. If you're doing this for underhood bling/clearing up some space for something else in that area (like a catch can) - go for it.

Lastly, AFAIK the stock airbox has no problem supplying enough air for 350WHP - unless your WHP goals are higher than this I would save the money and spend it on something else like cams or gears (without your mod list I don't know if you've already done this).

Whatever you decide - enjoy

The Vishnu red beast was making 560+whp using stock airbox....

Nuff said..

 

nope...which is again why i asked if anyone else had any figures for this intake

it never hurts to add performance and bling at the same time

yea we can get into which mods are better in which order and whatnot..but since this thread was about an induction modification, i figured ide throw this intake out there since i have posted about it in a couple other threads...but no one seems to be able to show any figures on this setup...

of course cams and gears are up next for me...but this airbox is a possiblity down the road...and it never hurts to have numbers to back up the $400 you just dropped on an intake

 

That's true

 

Vishnu car making 560whp? In the car and driver super car challenge it said it was only making 475 at the flywheel

 

That was on 93 octane. 560+ = racegas tune.
