RM99 Car AMP

Originally I had decided that 2 6.5″ mid range in the front was enough for my car’s sound system. But then when I was installing the head unit, I found out that the previous owner had left all the wirings for an amp in the car, including high-quality audio cables and thick power cables. And rewiring the whole thing would be a big mess so I decided to get an amp to make things easier. And this amp costs RM99 only, considering what it has in store for us inside.

Don’t believe what is written on it. 900W will blow any speaker into pieces.

Normally I won’t recommend anyone to go Brothers to buy stuff because many of their products are very low standard. But this amp is a bit different. It’s cheap but it contains something that most cheap amps don’t have.

A toroidal transformer! (the green donut thing with wires wound over it)

A little about why amps are more powerful with a toroidal transformer. Take your headunit for example. It doesn’t have a toroidal transformer. That means it only has 12 volts to work with. Most likely it will produce an output of +- 6v. But with a toroidal transformer, the voltage can be stepped up. Now the amp has maybe 24 volts to work with. So it will probably produce an output of +-12v. Using ohm’s law, current is proportional with voltage if the resistance is kept constant. The speakers windings resistance is constant. So with higher voltage, it gets higher current and thus higher output power. This is just a very rough view of how an amp works. For more info, do a google search ;)

We did an experiment by connecting a 12v car bulb to the amp’s output. The video here will justify the output power (around 75W RMS as estimated by Tan)

Soon I will get it installed properly in the car and to drive my 2 Blaupunkt speakers. Continue reading

My new Toyota Corolla SEG!

After a long wait for loans, agreements, payments and stuff, I got my car yesterday. It was exactly 1 month ago that I saw this car for sale on zerotohundred.com forums. I can still remember clearly that fateful day. I was surfing the web at Giant using my pda while waiting for my friends to finish shopping when I stumbled upon this gem. The rest is history.

Toyota Corolla SEG, year 95. Not bad for an eleven year old car ;)

I was already on the look for a car before this to help me get around KL and to work. I was considering over a MR2 and a Kelisa. Both weren’t really pratical because the MR2 only seats 2 and the Kelisa is not the safest car in the world. My mum suggested a Myvi, but the price was a bit on the high side for such a car. I wanted something cheaper, but better. So I looked around for 2nd hand cars.

This was the original post by the seller.

So after some arrangements through the phone with the seller, I went to look at the car with my dad who happened to be in KL at that time. And I can tell you, it was love at first sight. Everything was in great condition. I wasn’t expecting such good condition from a car that is about 11 years old.

The readings on the speedometer is not sufficient to measure the speed of this car. Seen here also is the shortshifter and a Tom’s steering wheel.

The car just received a new paintjob at the beginning of this year.

This car comes with almost everything that I need. A great engine (which you will find out later), suspension upgrades, brake upgrades, rims, anti-roll bars and many more. The previous owner was very conservative when it comes to modding this car. No loud exhausts, no big wings, no fancy bodykits and especially no cutting of stock springs. It was a very practical and comfortable car to drive around.

A slick tyre probably have more threads than this tyre.

It did come with a few setbacks though. There was no ICE. The previous owner decided that he wanted to keep his old sony headunit and speakers and amp. That’s the reason why I got the Blaupunkt speakers and the pioneer headunit. And the tyres are on their last threads. They were Bridgestone Potenza GIII tyres and they cost RM600 per tyre or RM2400 for the whole car. And the spare tyre doesn’t fit the front wheels due to the bigger disc brakes. If I have a puncture in front, I will need to switch one of the rear tyres to the front and use the spare on the rear.

If you are an Initial D fan and you think this engine looks familiar, you’re right. Watch the Initial D movie again, the part where Takumi’s dad transplanted a new engine into the AE86. It’s essentially the same engine, but his was tuned for racing.

Originally this car had a 1.3 engine in it. It now has a 1.6 liter 4AGE Blacktop 20v. If you go around looking under the hoods of other Corolla SEGs, you won’t find many Blacktops. If I’m not mistakened, there are only about 2 or 3 in KL. The Blacktop 20v is one of the most powerful 1.6 NA engines in the world. Instead of having 4 valves per cylinder, this engine has 5, 3 for intake and 2 for exhaust. This translates to greater air-fuel flow and greater horsepower. At stock setup, this engines churns out an amazing 165hp. My Nissan is also 1.6 but it gives out at most 100hp. And being a 1.6, it’s not too fuel hungry either =)

Altezza original exhaust.

My first experience driving this car was horrible. I haven’t been driving manual for close to 2 years and my clutch control wasn’t very good. The car died twice when I was driving it back to my apartment yesterday. The fact that it was using a racing clutch didn’t help either. It was harder than ordinary clutches and it must be fully depressed before shifting. But I am getting quite used to it after driving around last night and this morning. I covered close to 200km in just 2 days.

It’s literally sparkling when seen under the sun. At night, you can get plenty of privacy with your girlfriend since it’s tinted also ;)

This car is very very quiet. You won’t know that there is a beast in this car (not referring to the driver or the passengers) until it is too late. This car actually rip roads apart! You can still spin the tyres at 2nd gear. At fifth gear, you can still feel the acceleration coming in as you approach the end of the speedometer scale. It’s like nothing I have driven before. Even my brother who drove an automatic Toyota Supra twin turbo before said that both were comparable in terms of acceleration. The Supra is 3.0 liters by the way ;)

Diamond black paint. Those are not real specks of diamond, so don’t come chipping them off my car.

So overall I am very satisfied with this car. When I get my ICE installed and tyres changed, it will be perfect. This is going to be a daily driving car, so most likely there won’t be many mods done on it. Keeping it stock so people won’t know what this car is capable of. But one thing’s for sure, it will turn heads wherever it goes. Because Toyota doesn’t make black SEGs ;)

Weekend is almost here

Once again it’s Thursday. The most anticipated day will arrive in less than 12 hours. But this weekend is gay… ummm… I mean this weekend is going to be very busy =) I have futsal on Friday with Alvin’s friends, MAS futsal competition on Saturday, meeting up with Nick them on the same day and hopefully going skating on Sunday since I missed it last week.

WOW!! Finally Microsoft has realised that their 2MB free email cannot compete with Gmail’s 2GB+ free email. So they give you 23MB. Well, that’s a start ;)

We have started doing the third project. It’s a piece of metal with two holes to screw in a stud. A stud is a steel rod that contains thread on one side of it. I was determined to do a mirror finish for this project but unfortunately, the piece of metal that I used had too many pitting corrosions and is not possible to remove using hand tools only. But I did my best.

Here is a very close up shot of it. You can still see the metal grains.

Looks very close to mirror finish.

Wednesday went to play futsal at Shah Alam. Since KL is a big place, the entire journey, to and back again was almost 70KM!! The futsal pitch was just RM6 but the fuel cost for my friend’s KE-70 is almost RM10, no thanks to the recent increase in petrol prices.

The exorcism of Emily Rose, on set.

I was going to put one of the more scarier pictures, but I think you better go watch it yourself. We watched this movie last night and it was great. It was based on a true story and the true story can be found here. Continue reading

ASP week part 2

This is the second week of our aircraft standard practice module. After a good rest during the weekend, filing and sawing is much easier and painless =) We are almost finished with our bottle cap opener. I finished polishing today.

All this was done using files, saws, drilling machine and sandpaper only.

The “before picture” just to remind you how the metal actually looked like before any work was done on it.

Working really use up lots of food. When I am having classes, I can skip the morning break and not feel too bad. But now, if I skip morning break, at lunch time I would be half dead. So every morning I would prepare something to eat at the workshop. The canteen is about 1km away. Maybe 0.5km. But it seems like 1km when you are hungry and walking under the hot sun.

When it’s over, I get the rest of the day and night free =) Continue reading
