We Test the PTS-Joe Z IS-F Exhaust and verify K&N intake power!

^^^ I was referring to the article website. However, it is working now. It just takes quite a while for it to load properly. Probably some work filter crap.
So it sounds as though the K&N intake really is sustaining 22-25hp gains. For anyone who has the K&N intake, did you notice marked gains in performance?

My bad. Someone with the K&N please chime in because this is the first really documented and well tested intake that I've seen verified gains on. I'd really like to know if this is substantiated by a 3rd party with verified no interest in selling K&Ns parts. Not saying smartbomb is but we just have no way to know that.
They BOUGHT the K&N Intake and the PTS-Joe Z Exhaust to test out for themselves..
Plus, I meet Mike aka '"smartbomb" in person.. He has ZERO interest in selling aftermarkets part for the IS-F..
It's very clear what he does & what their Website is about..
Best Regards,
Joe Z

Interesting on the K&N...which was hyped and then quickly trashed by a lot of people here...as an aside smartbomb, I do appreciate the pics, writeup, and "scientific" approach you took to this testing...seems very thorough...thank you.

Do it yourself:
Buy a BLITZ TOUCH B.R.A.I.N. feed it with correct parameters of your ISF (WEIGHT, ENG.DISPLACEMENT, LOSS, GEAR, GEAR LOOKUP, etc...) and enter a nice straight and even highway... Push your car til Vmax (maybe 6 Gear)...
Every Value (OBDII) also HP/PS can be stored in memory and could be analyzed later on your PC.
Do it again with your upgrades and you'll see if there is any difference... (Numbers don't lie) haha...

We retested the intake because of requests from members here, also tested in sixth gear for that reason.

So I'll chime in with what I consider the most important part - the testing shows a horsepower gain. The testing is done consistent with standard practice so it is fair to compare these tests to other tests.
The testing infers these same gains with the car on the road, hood down, under normal driving conditions. This may or may very well NOT be a good assumption. As Powmax suggested, the BEST test is before and after, your car in running trim on a road or track with hood down, and in a normal drivable configuration.
Dynos are great for showing CHANGES compared to other dyno tests under similar conditions with the same equipment. The gains on the dyno do not always translate into gains in actual service.
Also - ANY intake removing the charcoal filter violates Federal EPA laws for tampering with emissions control equipment the same as removing a working catalytic converter from an emissions compliant vehicle is a crime in all 50 states.

First of all, thanks for doing the dyno test and sharing with us your results. However these results are considerably different that what I found when I had my K&N Intake and JoeZ Exhaust combo dyno:

As you can see, I didn't show any sustainable results, infact I lost some power. I spoke to K&N briefly about the results and one of their speculations about the results was that the K&N intake was designed for a STOCK IS-F (no exhaust, etc). I dynoed my K&N intake with the JoeZ Exhaust in place, where I noticed that you redyno'd the K&N Intake while still on the stock exhaust. I'm not sure if the change in exhaust would make that drastic of a change in the intake flow, but apparently it may have with my car. It would be interesting to see what the results would be if you redyno'd your car now that you have the JoeZ Exhaust inplace after some miles. Anyway, just wanted to share my results and see what your thoughts were in regards to my results. Thanks...Darshana S...

Consistency in run to run temps give the most consistent results.
