Cheap Horsepower

One advantage of turbocharged cars is that they can generally be modified to produce substantially more horsepower by just increasing the boost.

On any given turbo, generating additional boost is simply matter of having the turbo to spin faster which is primarily controlled via the waste gate.

When the Vios turbo first came out from the tuner back in April, it was only boosting 0.4 bar as we needed to observe the engine operations and it was only putting down 130+ to the wheels.

We then raised the boost to 0.6 bar and we gained an instant 10 horse making it 140+ at the wheels.

In June, we upgraded the stock coils to Okada Projects coils and we gained another instant 10 wheels pushing the final output to 150+ wheels with no change in the boost.

This also tells us that upgrading the ignition system is also beneficial as well, as we can see there are lots of products in the market such as the HKS Twin Power, MSD coils, Okada Projects etc but personaly I think CDI is the only way to go if you're planning to make some serious power.

Blue: 0.4 bar, Red: 0.6 bar

Green: 0.6 bar with Okada Projects coils

Currently, we're suspecting there is a leakage somewhere as we can hear noises from the cabin when the car is in boost.

We will find out soon enough when the car goes in for a full engine rebuild.

(Update 21/08): Turns out the exhaust gasket was cracked due to excessive installations and removals. Got it fixed and we're good to go again.

I came across this video and I can't help but wanting to post it up.

Stage 2 Turbo Project - 1NZ-FE Forged Pistons & Billet Conrods

(Update 23/02): We ordered a replacement set as we found out they were actually high compression pistons.

I recently ordered a set of racing pistons and conrods for my car, and the Malaysia Customs had a problem with that.

And since I am a law obeying citizen I am more than willing to pay for taxes of any goods that I import, but hell I am not going to pay for something that is not reasonable.

I mean, they even wanted to charge me taxes for the shipping fees as well.

Without sharing all the glory details, I've managed to obtain my goods without paying a single cent at all and there is nothing they can do about it.

All I can say is that Malaysia Customs are not only stupid, they're fucked up as well. And I will say this once again.

Malaysia Customs are not only STUPID, they're FUCKED UP as well.

So to those who asked what killed motorsports in Malaysia, now you have the answer to it.

OK rants aside, lets get back to business.

It will take at least a couple of months for the forged internals to go in as they are oversized pistons so we need to bore & hone the engine block, not to mention converting the fuel system to a return setup, wiring for the standalone engine management etc.

On top of that, my tuner is so tied up with all the upcoming race events until end of the year I doubt they will ever have time to start work at least until early next year. *sobs*

I am also currently deciding whether should I ditch the automatic transmission gearbox and chuck in a manual gearbox with LSD.

Garrett GT2056

Lots of people have been asking me how does the GT20 turbo that I am currently using looks like so I decided to snap a few pictures and post it up here.

This GT20 turbo that I am using now is considered a rare turbo as it was a custom made model by Garrett Thailand as it has additional water lines feeding to the housing.

It was hand carried back by GT Auto's Toby all the way from Thailand.

There are only 2 units available, one went to my car and the other one went to GT Auto's staff car.

This is not my car here, it belongs to one of the staffs working in GT Auto.

The car was involved in a minor accident the other day and the hood and bumper was removed for repair works so I managed to snap some pictures of it.

Now do not let the size of the turbine fool you. This little fella here is rated to produce up to 260 PS.

Sepang Drag Battle 2009 - Round 3

Yesterday while waiting for my car to be washed at Sunway I walked over to GT Auto's garage to grab lunch with both the master tuners Thomas and Toby.

The crew hasn't been sleeping for more that 48 hours as they were busy preparing the race cars and not mention the countless hours on the dyno machine tuning the cars.

So the following conversation happened while we were having fried kuey teow at the Sunway foodcourt.

Me : Eh bugger, you don't need to sleep ah? Wanna become god issit?

Toby : I still got 2 more cars waiting lah, how to sleep?

Thomas : You don't know meh, he drinks race fuel wan. No need to sleep keh.

Me : Like that when only you got time to do my internals and standalone?

Toby : If you can wait, year 2010 lor.

Me : Mahai, want so long meh?

Toby : Your pistons and con rods arrive liao meh?

Me : Yah, but currently stucked at the customs. Monday need to go settle.

Thomas : So tonight you going Sepang to see the drag battle ah?

Me : Wanna go but no kaki leh.

Toby : Tiu we both here not considered kaki ah?

Me : You didn't say you guys planning to go also?

Thomas : Ok lah, tonight you follow us to the pit lah let you experience a bit.

Me : Can can, I call David also.

We were then handed a pair of official GT Auto crew t-shirt and off we went to Sepang. I was pretty excited as how often do you get to be at the pit as a guest crew for the tuner of the fastest drag car in Malaysia?

We were stationed at pit 17, and we have our 10 second street legal Mitsubishi EVO 9 that won the previous round in the drag battle competing in class A and a new Honda CRX in Class C.

Unfortunately, both cars wasn't able to get any standings as our EVO9 was spitting out transmission oil and the CRX was having problems with the toe & caster setting resulting our driver wasn't able to full throttle due to unstable launching.
