Hello my name is Drew and i work with a company called Level 7 Motorsports out of southern illinois. We have been designing intake systems for hondas for a little while now and we designed one for the S2000 chassis. The opportunity came to test the intake system against a oem setup to compare IAT temps and overall performance.

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.

not that their website works or anything lol
*edit: found it here. googleeee http://level7motorsports.blogspot.com/p/parts.html

was there any tuning done with this? or is this just swap for swap? possible more gains with flashpro tuning?

^ this was a straight swap. oem for level 7. nothing else was done.

phunhaus

Quite a pleasant surprise for sure! Congrats to Level 7 for a great product.

so many haters on s2ki though, maybe because a redneck in a garage at the bottom of Illinois built an intake that makes more hp then their beloved password jdm one.

Yeah, but that's with the hood open. I bet with the hood closed, on a hot summer day, that intake actually loses power> Just like the fancy ARC intake. They become heat soaked hot-air intakes, it has nothing to really draw "cold" air in with the high under-hood temps. Your design looks like a copy of the ARC intake, no offense.

no offense

What dyno were these test performed on? 177whp from a stock s2k sounds like it had issues.

vactor

does it matter? it's a reference point, and one the changed with the use of the intake.

Read the article.

177 sounds about right for a bone stock s2000 actually.

I should of figured people are going to hate on something that is new but the proof is there that this is a nice upgrade from stock.

phunhaus

It's a Dyno Dynamics dyno as shown in the pictures of the dyno plots. With your experience, what have you seen stock S2000's put down on a D.D. dyno?

Thanks, I should've read the article...as the level 7 folks stated. I've never tested on a D.D. myself, but other people on here seem to think they dyno around the 190ish range in stock form (AP1).

Boots

it all depends, there are a lot of variables to take into consideration...ive seen them dyno anywhere from 175ish to 201 stock...different dynos, different ambient temps, mileage and condition of the car, elevation, etc. it all plays a factor

Boots

fyi, skittle, the car looks great

crxfornow

thanks for the input guys

Thanks sir!

Stock AP1 making 240 at the crank and 170 at the wheels? sorry but it just seems reallllly low.

I'd like to see the same car on a different dyno setup, as well as an AP2 w/ & w/o the intake on 2 dynos as well.

Give us some more validation that this intake is delivering the perforemance increase.

vactor

so a reference point and a delta point on the same dyno and same day within hours of each other on an other wise bone stock car with no other mods or anything else is not something that you think is reliable?? interesting.

JUSTINTHECOASTI

Pay attention to the earlier posts...yes AP1's are RATED at 240hp however the type of dyno used will show a different/lower whp. The OP has given enough information showing that this intake does show gains, what more do you need? Based on his dyno, he made 177 stock and 191 with his intake, a 13-14hp gain. On this type of dyno try not to look at the power and focus more on the gain(s)

crxfornow

i can understand if the runs were on different dynos or even on different days but we tried to eliminate all possible variations to show a solid comparision between the two, i dont see how we could of done it any better.

I agree 100 percent with JUSTINTHECOASTI the point of this was to show gains not to show how much power a bone stock ap1 has

SL0WEGG

Nice work Drew & the guys at Level 7. Some need to focus on gains more than numbers. Dyno's are used as tools and that's all it should be used for. When looking for gains, you always need to do a baseline(check) and then did a pull with new part(check). 13-14whp gain sounds solid to me on just an intake swap
