Subaru WRX 2.5L for 600 bhp


Subaru WRX 2.5L for 600 bhp

Eh, this turbo is super duper turbo lor... sillypore not many. I take this chance to pay my respects to WL, he has the winner ride everyone wants. Ah joe and WL departure has affected alot of us and their rides is an example of fine workmanship, it is a pity that good racers do leave us.

WL's ride runs on this super duper turbo and on 40 tiang... my red wrx only manage to keep a close distance on the initial 2 gears, on the 3rd gear, WL is already 2 lamp post in front. On 4th gear, 3 lamp post in front. The exhaust was roaring through the 3" straight through exhaust system down the alley.

Before the second drag, WL's front diffuser gave way. Sam fix it up on the spot... our dear 7777 was there also that night. Witnessing this race is definately an eye-opener. Deep down I wanted to raise another good ride to win WL's ride. When I heard of his departure, my heart dropped.

WL owns the ride that wins. Kudos.

Ok, to breed another ride like that is not easy. Alot of kungfu is required lor.

When Siao jian's ride was fully tuned to 1.9 bars of boost, something gave way... the wastegate refused to open! cbb lor... 7777 owner was in the car when that happened. knn, just 1 pull at 4000 rpm and suddenly, boooom! A series of white smoke came puffing out from the exhaust... knn, somemore can make o-rings lor... the feeling is damn shitty lor.

This engine to build 500+ bhp, we just put in a forged pistons and conrods lor... then already finished tuning 1.9 bar of boost then this sort of things happen...

As a tuner, this is something very very disheartening, standing beside a injured car is something everyone dreads. When things like this happens, the standard procedure in investigating the cause starts.

You can determine whether is the tuner's fault or not based on this investigation. The very reason for not pushing cars past their limits is to avoid situation like this lor.

But, like all things, shit does happen.

This investigation is very well established as I write, since so many incidents have happened in the past to so many people, the procedures and protocols are well adopted by all workshops as fair and non-bias.

Ok, pistons and conrods reveal no pingings, no lean or over fueling. The sleeves of this engine broke. The pressure from the turbo is so high, it generated so much pressure, enough to split the engine chambers. Blowing an engine with perfectly tuned maps... hmm... they say I good... I fark them lor... hahaha... feeling suxs...

Building a 600 bhp car is no simpe feat. No one says its easy. And wastegate jamming on us is definately a lousy thing to happen.

Ok, this ride now comes with forged sleeves, my maps interpolated for 2.4 bars of boost. This valuable experience of 2.4 bars of boost comes from another ride with forged sleeves, cams, conrods, pistons, valves springs and retainers. Having tune a 2.4 bars of boost, I know what is required for siao jian's ride.

sam's still working on this ride and I certainly look forward to seeing this ride in action. Once this ride races, I'll definately post up some video clips here... kekekeke...

once again, this ride comes with so much installed, I'll leave the details to the next time I tune this ride.
