Immediate experience:
I experienced increased acceleration and increased sound pressure.
3 hours later:
I experienced a dramatic increase in acceleration, especially at mid to high speeds, and increased sound pressure.
7 days later:
I experienced a dramatic increase in acceleration at mid to high speeds, as I had 3 hours or more after installing the product. The sound pressure was also increased, and the voltage was stabilized. The engine sound is now quieter than before, and this is partly due to the fact that I have installed various parts in addition to this product.
Audio Impressions:
I put my F4350 in the middle of the amp instead of a capacitor, and I also connected my CAP1500A and 2500B to the battery, which increased the sound pressure. The amp settings were also reworked for the best sound.
Other:
I had installed many of these products in my Toyota wish, but when I changed my car model and visited this site after a long time, I saw that the latest model was on sale again at a special price, so I bought it immediately. I am very satisfied with the product and I love it. I will continue to support ROSSAM.

Immediately after experience: I could feel a shortening of the cranking and a quieting of the engine.

After 3 hours: I have a Cerespeed, which is a robotized manual transmission,
The shift change response is much better. I used to have to press the paddle switch and then
After installing the F8450, the gear shift is now done with a "buzz".

Experience after 7 days: The response of shifting gears is even better while maintaining the same effect as immediately after installation and after 3 hours.

Audio impressions: The sound outline has become clearer.
The dynamic range has increased and I can hear sounds that I couldn't hear before.

Other: I think the effect is great for single clutch robotized manual transmissions such as Alfa's Celespede or Fiat's Dualogic. It feels great to switch gears in a snap.

Immediate after-feel :
Silicone smell when charging, I always think I got it. Acrylic is light, engine braking is light when dropped into s-range. Headlights and panels are bright when in the tunnel.
3 hours later Experience:
I gradually got used to it and the gas pedal felt even lighter. Torqueful when stepping on the accelerator and acceleration became better.
7 days later Experience:
The above items are still the same, but I drove with the minus wire disconnected and the car became heavier. Acceleration also seemed sluggish. However, the F8450 is still installed. I thought that if I wanted to drive in a normal fuel-efficient way, I could leave it as it is. However, since I wanted to take driving over fuel economy, I preferred the 2500 installed to turn better and be more powerful. I think the sport type is more fun with more capacity.
Others:
It is always difficult to find a place to install.

Immediate experience:
Engine cranking time is shorter and starting is quicker.
Idling became stable, smooth and quiet. Acceleration at startup is better.
3 hours later:
Torque is thicker in all ranges and no longer falters when shifting gears.
Acceleration is sharper and 20% more powerful.
7 days later:
Torque is thick enough to accelerate even from 1000 rpm. I was originally satisfied with the engine's high RPM extension, but after installing this product, it became like a different engine. It revs without hesitation with power all the way to the red zone. And the sound is great.
Audio Comments:
The sound was a little flimsy, but it has become more precise. Noise was reduced and dynamic range was expanded.
Other:
It's old, but it's a high performance car that still works well today. I had done a lot of work on the intake, exhaust, and ignition systems, as well as computer tuning, and I thought it would be impossible to improve the performance any further, but thanks to this product, I was able to bring out even more of its potential. I think it is an excellent match for cars with modified ignition systems. We use T.M.works Ignite VSD 16V to increase the voltage to 16V and Okada Products Plasma Direct to make multi-spark. 2500A has brought out the performance of these parts to the limit, which has definitely led to the performance increase.

Impressions are that the fuel consumption is not increasing, but it is the result of having fun and stepping on the accelerator pedal. Still, I think it's a real increase since it hasn't dropped off.

I actually connected another 2500A.
I was just curious, so I didn't think it would make much difference, but I was pleasantly surprised. The torque became thicker and the acceleration became more terrific. I can't go back to the way I was before.

EDLC Awareness: I knew about it

Our vehicle is not very fuel efficient because we have an external full-computer, large diameter throttle body and high-flow injectors, and it is a bit dense. It was also a little thicker, making it difficult to drive at very low speeds.
So when we first installed a device to convert the primary voltage from 12V to 16V, fuel consumption and acceleration improved considerably, and to be honest, we thought there would be little further change.
I was surprised to find that the engine could run at around 1000 RPM without stalling, although it was knocking when I tried driving in 6th gear with the gas pedal off.

Other: Startability is noticeably better. I was surprised.

F8450 Car: Honda Mobilio 1.5 Year: 18 M・M, Nishihara-cho, Okinawa, Japan

I purchased your F22 and F16 batteries several years ago, and when I purchased the anniversary model, I tested them with an inazuma tester. Although not measured by a clock, the results were similar to the catalog values, and I was able to confirm the reliability of the products in the engine compartment in Okinawa.

Fuel economy improved 14.3 Km/L ⇒ 16.3 Km/L (14% improvement)
Fuel Economy Gauge: Fuel Economy Gauge-equipped car
Satisfaction with product: Especially good
Awareness of EDLC: I knew of it

Immediate experience:
I drive with concern for average fuel economy in eco-driving, so I have never been concerned about medium and high speeds and cannot describe them specifically
Sorry, I can't.　When I first bought my Mobilio, I got 15.6km on normal 185-65-14 tires and averaged 15km on Eco-runs.
When I switched to wider 205-55-16 tires, I got 14.6km on Eco-runs and averaged 14.3km. 14.3 km.
With the anniversary model, I got 16.3 km (more than my best record with the normal narrow eco tires) and this record was set in Okinawa, Japan in late June at 28-31 degrees Celsius.　The record was set in Okinawa in late June at 28-31 degrees Celsius. The highest fuel consumption record when I purchased the Mobilio was set in March, so there are high expectations for another record in February or April.

F2150 Mr. OK, Higashi-Osaka City, Osaka, Japan Triumph Rocket 3 (2006) 2300cc
2 passengers at test
Distance traveled: 122 km (continuous)
Course: Highway 50 km + mountain pass 40 km + city 30 km
Impressions (changes after F2150 installation)
1) At startup: Bouncing start feeling (Cell turns at a speed like a different bike)
2) Idling: Increased about 10 % (from 850 RPM to 950 RPM) (Tachometer reading)
③ Light system Headlight quantity UP Each meters quantity of light UP Indicator lamp quantity UP (All these are improved to the dazzling degree compared with before)
④ Fuel consumption Improved from 9.6 km/L to 11.5 km/L (about 20% UP)

The person (my son) who had been servicing together before also completely agrees with the above contents. I am very happy with the product. I would like to thank ROSSAM for providing us with such a wonderful product. I look forward to more great products like this in the future.

F2150 Car name: ek wagon Year: H21/7 E.M., Ebetsu-city, Hokkaido, Japan

Battery age: 1 year
Number of batteries: 1 battery installed
Fuel: , Regular
Engine: Recipro
Transmission: Automatic
Audio Quality: Better
Initial Acceleration: Better
Fuel Economy: Better 10 km/L ⇒11Km/L (10% improvement in fuel economy)
Product Satisfaction: Good
EDLC Awareness: I knew about it

Immediate Experience: I had been driving a 5-speed manual transmission until then.
Was it because of the 3AT because I had been driving a 5MT until then? Is it a tendency of Mitsubishi? I had a heavy feeling on the accelerator pedal, but it has improved.

7 days later:
I did not see an improvement in fuel economy as I expected at first, probably because I installed it when I changed to winter tires and warmed up the car at the same time, but after about 3 months, the results have been better than I expected.
Before the installation, I could barely drive 10Km/L with summer tires, but now I can drive 11Km/L even with winter tires and warm-air operation. Sometimes it runs close to 12Km/L.
Audio Impression: I guess it is a matter of personal sensation, but I guess it has become easier to listen to. I used to listen at 12-13, but after the installation, 11 is now enough for me to listen while driving alone.
Other:
I am not familiar with cars, so I can't give specifics or details, but I am still happy with the improvement in fuel economy. Also, since it is a 3-speed top, the car still seems to suffer when I keep accelerating from around 40Km/h until I get to 60Km/h. However, the acceleration is much better when starting off and the weight of the car when accelerating has been reduced.
I will add a note if there is anything to report as I think there may be a difference after changing to summer tires.

F2150 Peugeot 306 Mr. YO, Katsushika-ku, Tokyo
Battery age: 3 years
Number of batteries: 1 battery installed
Starting: Better
Headlights: Brighter
Idling: Stabilized
Room lamps: Brighter
Audio/radio during acceleration: Sound is not choppy
Initial acceleration: Better
Acceleration in mid speed range: Better
High speed range Acceleration at high speed: Better
Fuel economy: Better Fuel economy figures: 7 km -> 9 km
Product Satisfaction: Especially good

This is a report on high speed and fuel economy that I could not report last time. I had given up on the acceleration from 70 km/h on the Metropolitan Expressway as it was only 1800, but the acceleration in 3rd, 4th, and 5th gear was also clearly improved. I happened to see the same 306, but I was able to lightly leave it behind.
The car is lighter and I am enjoying the fun of driving that I never had before. On ordinary roads, the amount of accelerating is clearly reduced because the speed is good, and as a result, the fuel consumption has also improved. Once installed, I cannot take it off! I will put it on my Skyline and Porsche.

We received an evaluation of ROSSAM F2150 from the headquarters of a car store affiliated with an automobile manufacturer.

EDLC F2150 Test Results

1 First impressions immediately after installation
☆ First of all, I was surprised at the improvement in audio quality (described in 3) and the reduction in time it takes to connect the air conditioning compressor. Normally, the majority of users stop the engine without turning off the air conditioner. The compressor is not connected at the moment the engine is started, and it automatically "clicks" into place after the engine is started. The time it takes to make that connection is less than half. If you ask me if that is any benefit, there is none, but it is a phenomenon that became noticeable as soon as the EDLC was installed, and I believe that the electrical enhancements made it so.

2 About engine quietness
☆ Regarding quietness, there is no change that can be felt, partly because it is a large displacement 4-cylinder engine.
　Since the engine is a longitudinally mounted car, the cooling fan, which is directly connected to the engine, is left running, and the engine sound itself may be difficult to recognize due to its noise.

3 Improvement of audio quality
☆ This is an amazing and remarkable improvement. The resonance of a piano and the depth and reverberation of stringed instruments come out beautifully. In addition, the "don" sound at high volume can now be heard clearly. Until now, the "dong" and "nong" sounded smaller, but now the "nong" sound comes out more clearly, making it possible to slightly tighten the bass on the tone control.
Also, the wide range has been cleaned up so that it is no longer bothersome, and it is now possible to lift the treble.
It makes me want to listen to various CDs again.　I can highly appreciate the improvement in sound quality.

4 About the difference in acceleration and the effect of driving
☆ Acceleration has improved. Re-acceleration after slightly stepping on the brake at intersections is no longer jerky. Also, acceleration at high speeds is more stress-free than before. It is a feeling of reaching the same speed with less pressure than before.

5 About fuel consumption
☆ An average performance improvement of about 7 to 10% can be confirmed.　The higher the speed, the greater the improvement.

6 Other changes we noticed
☆ When using electrical equipment with a large load, the phenomenon that idling staggers for a moment when it is activated has been improved.
This is thought to be because the idle control valve is now operating more accurately and the injector operating voltage has been increased.
