Intake manifold testing.
WOW 43WHP over stock!!!
Can you copy it and sell it for half the price?
Im sure there will be a lot here would like to buy that!

Im sure there will be a lot here would like to buy that! Well this came as quite a shock, why I'm not sure as HKS has proven themselves to be a leader in Japanese motorsports for a long time. I didn't even want to take the time to pull the Kansai intake off our black drag car. I was just going to replace it with whatever I found to work best. Well I am sure glad I decided to test it. Holy crap.
The car made 649 whp/479 ft lbs. That's a gain of 43 whp over stock. Nothing else has even come close.
The losses down low are also some of the smallest of all the intakes.
This is the most expensive intake of all we have tested, it is around $1700. It has an super nice billet adapter to use the stock throttle body with it and we did us the stock throttle body again.
Anyway, here is the dyno sheet. This one is going to be hard to beat.
**NOTES ON INTAKE MANIFOLD. NO EGR PROVISION, NO STOCK MAP SENSOR PROVISION, NO DIPSTICK MOUNTING HOLE. IT IS FLANGED FOR THE Q45 THROTTLE BODY BUT COMES WITH A VERY NICE BILLET ADAPTER TO MOUNT THE STOCK THROTTLE BODY. INTAKE ALSO HAS BOSS ON THE BOTTOM FOR AN ADDITIONAL SET OF INJECTORS. THE INTAKE WILL NOT CLEAR US ABS EQUIPPED CAR WITHOUT REMOVING OR RELOCATING THE ABS. REQUIRES OUR UPPER I/C PIPE TO BE MODIFIED TO FIT.

Hey David, just out of curiosity, what were the differences in the ambient temperatures today versus the other days that you did the intake manifold testing. I know that it has been absolutely frigid here in northern Ohio these past couple of days. How much of an effect do you think this would have on the outcome of the two tests, the stock vs the HKS Kansai?? I'm am pretty sure the test that you conducted on the stock intake manifold was done last week, unless you did do a pull with it on today?? Otherwise, I appreciate you doing these tests for the community. You have helped me out alot.

David, could you please measure & post the length of the runner of the hks intake, from flange to airhorn length + take a picture of the plenum, showing airhorns?
Thnaks.....damn, that mani works....
the runners look longer than anything you tested, but less than the oem manis

No suprize to me at all. I first had the magnus intake on my car which sucked and kept breaking and seams splitting. I then had the AMS VSR intake which was very well made and much better performing. Then I went to the Kansai HKS unit and really liked the way it fit in the car and also noted a significant MPH gain over the AMS unit.
I use the Q45 TB and I love it and the manifold
Sometimes in life you do get what you pay for

Instead of everyone think to copy this fine unit - why not just save up and buy one - the designers certainly desreve to be compensated for a job well done
If every product is ripped off by cheaply made chinese junk n one will spend the time to make great products
here are some pics from my engine

Thanks for posting the pictures guys.
I will post internal/external pictures on our site when I get it off the car.
Don't run out and buy any intake yet. I still have the Hypertune to test still and it appears to be a very well designed part.
As much as I don't like paying $1700 for an intake manifold I don't want to see them knocked off either. I am with Al, why not pay the price and support the company and engineers that figured it out.
One more intake. To be honest I'll be glad when the testing is done.

The test might be tomorrow, it is going to be a lot of work to get the next one on. That is why it is last on the list. I would like to get it done tomorrow as my EVO X should be here Wedneday and I am going to be buried in that project.
Something else I missed. The weather conditions today, yes it is cold as hell here today.
I have been keeping the AIT's as close as possible to each other as I can. Which is very close. I think most of the testing has bee with starting AIT's of 59 degrees and I have been using the fan on the dyno too. Today because it was so freaking cold I knew it could mess with results so I kept the dyno room (seperate building that is 28x24) closed. It is heated so I swapped the intakes and then loaded the car very quickly on the dyno (car has to go outside and back in to go on the dyno) Then we closed the door behind the car to hold the heat in the building. The very first pull with the Kansai the power was actually 661, I looked at the log, noticed it was in the 12:1 AFR's and that the AIT's were only 45. I got out of the car, turned the dyno fan off. I then finished tuning the car with the dyno fan off, so the AIT's were going up each time. The intake actually made this power with no fan and the highest AIT's of all the testing. The final run where I got the AFR's back into the mid 11's I had a starting AIT of high 60's that went up into the 70's. So if anything, I could have made more power had I turned the fan back on.
