The conclusion was 13hp over stock with almost a 10 degree difference in intake temps.

check it out, any questions just ask

Recently I took a trip to Chicago to have my S2000 intake system installed on a customer's car for some testing. I wanted to gathers as much information as possible to help inform customers wanting to purchase this system. I called up one of the Chicago area's more premiere honda shops, Suja 1 Motoring, to see if they were willing to do some dyno testing. They were willing to install the system on a customers car and help me with whatever testing I needed to conduct.


To start testing they put the car on their dyno dynamics dyno in stock form. The test car is a completely stock AP1. During our testing of the stock intake, ambient temperature was 85 degrees, 43% humidity, and 29.21 in/hg pressure. The first test conducted was meant to test the intake air temps at idle. The car was left at idle for 5 minutes. Coolant temperatures reached 180 degrees with the IAT reaching 146 degrees. For our next test they drove the car on the dyno 30 mph, in 4th gear, at 2500 rpm with the fan blowing into the front bumper opening. Covering a distance of 3 miles, the factory system allowed the IAT to drop to a lowest temp of 139 but averaged a temp of 142. For the final test of the factory system they immediately did a full throttle run. During this run, the IAT dropped down to a 133 and the peak rwhp was recorded at 177.4 All testing of the factory intake and Level 7 Motorsports intake was performed with the hood closed.



Instillation of the intake took right at about an hour. This included removal of the factory intake, installation of the new system, as well as routing the fresh air duct from the intake to the front bumper grille. The new intake does have provisions for air pump, valve cover vent, as well as a bracket to mount the evap lift soleniod. I will mention that this system is lined with the DEI heat lining and is using the fresh air duct. Both of these are options when ordering an intake system. If you look on the parts page it will show you a price break down.





For testing the Level 7 Motorsports intake, they repeated the same process as with the factory system. Again, the car sat idle for 5 minutes for the first test. The coolant temperature stayed at 183 while intake air temperature kept solid at 141 degrees, 5 degrees cooler than the factory intake. For the second test, they drove the car another 3 miles on the dnyo, in fourth gear, at 2500 rpm. The lowest IAT recorded was a 132 but averaged a 133. This test was conducted with the fan blowing into the bumper opening. This temperature was 9 degrees cooler than factory. This is due to the intake having fresh air blown into the bumper mounted fresh air duct. For the final test they went straight into a full throttle pull. The car made a very impressive 190 rwhp. Intake air temperature dropped to a 124 during this run, 9 degrees cooler than factory! Just to confirm the results, they did one more full throttle run. This time power jumped to an impressive 191.3 rwhp. This made for a gain of 13.9 rwhp over stock.

I think this is very interesting, and can see much more potentiol in this than the "Puffo Passion Intake" that everyone was getting frustrated over the past few months...

But lets talk heat soak, you think this would suffer more heat soak than a FIPK? I cant see how considering its enclosed, and the filter isnt sitting bare to soak similiar to the arc design. Im sure one could also get the letters covered if that much is really causing any heat soak. But from the looks of it, seems to be a great idea. But maybe have the snorkel go down to the bumper vents (Ap2 i know has a one perfectly for a CAI)

Until I see independent testing, I'm going to have to call BS. The intake temps are ridiculous and it's highly unlikely that an intake would achieve such gains over the whole RPM range.
