ermm look like nowdays simple mod can gain lot of power hehehe..maybe coz the fuel is expensive so the engine will generate more power hehe

WOW!! very fast for 4G15.

To get sub 10 sec for a 1,100kg car like the Wira, the h/p should be around 150~180 on wheel.

I'm not convince the mods you mention are able to yield that kind of power. Maybe you got some secret weapon you're not telling us...maybe like Surbo or Micro-compressor, K2-link Super Duper power gadget thingamajik, etc, etc.....

12oY,

I think his 4G15 is fitted with 1.6 pistons...... otherwise 8.5 seconds is really kind of impossible....But I am unsure, coz 4G15 twin weber can kick ass......

     

12oY

that not my engine hahah... no la i fitted oversize piston la.... just 0 - 100 only power other suck lo....4g15 engine cant go much more unless heavy mod la... but really can 8.5sec lo

bro i am the mechanic ... i fix myown oh....

i wan say is the most important is the clutch set no much slip so more the power is fully transmit to gear box compare to ori cluth set...then engine running stock is for save fuel so the power not fully utilise.. is depend how we understand the engine and how engine work and how to tweek the engine for performance and how for economical all we need is to undestand so we can tune to better porformance ... yas i admit 4g15 engin cant go much power band but abit sure can...4g15is not a powerful engine but for learning sure is a good basic engine.... chear i still on learning
