[@zerohikari2685]

You need headwork. The K20 head does not have enough flow stock to make power past 9K RPM NA. You'd need a port and valve job. Even then, the engine is too squared. It's literally not designed to make power there. You will never make power near even 9.5K and not need a rebuild every 300 miles because your valvetrain is destroying itself. Give up on chasing power and just enjoy the car.

[@travisfabel8040]

@10:53. This is useful information. Instead of just having a filter directly over the intake trumpets, put a box that clicks in to the filter mount, and have a duct Go over to somewhere for a cold air intake. The problem isn't running an air filter. The problem is you're running an air filter directly on top of your velocity stacks. This is always a bad idea for power. Look at every single sport bike. Not only do they have velocity stacks like yours with ITBs, but they will use a panel filter located away from the top of the stacks. Filter fills a box like a plenum, and that box feeds the trumpets just like open air.

A lot of people run mesh screens on the itb it will prevent things that can get stuck but doesn’t restrict air as much now since you won’t catch the particles from the air you will have to do you oil change more often to make sure no debris clogs the oil passages but that solves being able to run itb’s without a filter just like big turbo guys just put a screen over the compressor housing

the air gets hot as its sucked thru the spongy membrane. Its not because the filter is hot or anything, but its because of the filter density. the ITBs would be mainly for responsiveness and noise as well as underhood sexiness but i would have gone to smaller diameter trumpets to improve air velocity...

[@sqkang445]

I owned an 09 SE3P S2 R3 for 4 years before mine went to an 06 AP2. Although I'm bound to get a rebuttal for saying that. But the R3 drives fantastic. I know I can't forget the feeling today! I put the DFV on R3 to get a little camber and it was amazing in the corners. And it's a much stronger car than the FD3S. I would say the unmodified 997.1 Carrera is not as good as the R3. The S2000 has similar power to the R3, but for me there was a bit of torture and I couldn't enjoy the corners. I need to focus on the rear wheel all the time. It was even willing to turn excessively on freeway ramps. The factory settings on both of them are enjoyable, but if you want power, they both need to be supercharged. The se3p has the turbosource kit, or you can swap 13b-rew, or 4 or 5 rotary, that's absolutely evil. The S2000 being a Honda doesn't need to worry about mods, you know.

to combat the heat soak issue you might try to build an insulated snorkel box. The s2k I believe has a void behind the driver side wheel well, you might build a duct into the snorkel over there and itll allow you to control the intake air temps a little better.

[@roda1999]

bro i love this channel, andy is a very well versed mechanic, but just like you i think those number (k20 high comp + itb) are garbage.

[@bruce_son]

On STD correction? They always read about 5% higher than more common SAE correction. Also, ITBs are super difficult to tune to correctly make power. You need the correct combination of all parts for it to work well which I believe is the source of their problems. I suspect they could make more power going back to the stock intake manifold. You lose the inertial tuning effects of the plenum and intake piping. However, it’s still possible for them to change runner lengths via trumpet sizing.

[@markmartin7384]

Less displacement, stock heads, and ITBs are probably too big slowing airflow

[@JonHop1]

@@GalliJZ Its not tho... Its important that Dyno's are calibrated to be consistent, so customers can get accurate and consistent readings. If you go to one shop, get 240, and another shop reads 210, it can be thought there is a problem with your engine. So no, its not stupid at all...

I've always said, exhaust scavenging is super super important

[@of_lion22]

Runner Length. There are basic calculators out there to help you find out a good length to start with. ITBs are extremely sensitive to tuned lengths. Ben if you haven't yet, check out Garage 4AGE. He's got many well documented dyno runs on his 220whp 10,000 rpm ITB Starlet and thats with 1.6 liters. Look closely at the intake runner length videos. The length needed to make best power across the range is way longer than you'd expect. Some of it can be fixed with Cam advance. Then as found in the video, you have the tuned length of the exhaust, which the engine is much more sensitive to on ITBs. The same concept was proven in Garage 4AGE's K24 tuning videos (normal intake manifolds).
