Tuning my Airtrek

[stutzedward]

241whp & 332Nm wtq @ 1.2 bar. I am running 1.5 bar now. Estimated around 270whp.

waaa.. very powerful..

 

[stutzedward]

haha.. no la... its just standard power bro....if it goes above 300whp, that's powerful!

 

[4gbanger]

hurm.. wonder how our invecs-II handle so much power... btw i saw u have speed meter on ur dash the other day, did u test treks top speed yet?

 

[stutzedward]

Invecs can hold up to 300whp max. Over it, it'll have reliability issue. Max I've touched is 200kph only. That's before tuning. I didn't wanna go faster.

250-260kmh no prob la...trust me

 

[stutzedward]

Wow u tried before?

 

[4gbanger]

i'm sure i'll be ok.. even ralliart meter cluster put 260 kmh max... for sure 260 kmh were there for a reason...

 

[stutzedward]

Well, I dare not drive too fast especially with family in mind. I don't mind sprinting but not highway top speed. So never tried before.

 

[4gbanger]

its ok.. drive safe.. only when road is super empty, then can go fast...

 

[stutzedward]

My personal best is 200kph. And for the longest distance fast driving, I've driven from Singapore Beach Rd till my home in KL around Kinrara area (point to point) in 3 hours 10 mins. Yes, that includes going thru 2nd link custom too. 2nd best time for the same journey was 3 hours 15 mins.

The shitty autobox has really good final gears, so even when travelling around 160kph, the RPM literally hovers around 3500 only. Hehehe...

 

[4gbanger]

i wonder any speed ticket?

 

[stutzedward]

Back then, I can still use the radar detector. It was before AES. Now.. cannot already ler...

 

[4gbanger]

why the radar detector cannot detect AES meh?

 

[stutzedward]

Yes... the one I have cannot detect. Maybe the wave is new and not recognizable by my detector.

UPDATE: Retuning was done but then, it's not on the dyno. So I do not have any numbers to prove. It's already 241whp @ 1.22 bar, so I guess it is possible seeing 270whp @ 1.5 bar + downpipe mod.

FC is still pretty bad at around 5.9km/L as opposed to before tuning @ 6.3-6.5km/L. Surprisingly on highway driving, I am getting 11.84km/L. Best I get so far for long distance. With more power, I guess one has to pay more for it.

No more mods for now, maybe next year. A pair of decent cams + adjustable pulley to push it over the 300whp mark. Let's wait and see...

Dun forget your GB cannot last long with more power... :top:

How's life bro, long time no see la... :)

I am not trying to argue the gearbox is okay but we already have quite a few strolling around for years with power around 250-300whp on the stock slow-box. But then, defintately more stress on it, hence shorter lifespan.

 

[4gbanger]

maybe its time for manual conversion????

 

[Dayline668]

Fine bro... Craving for more power i see..
