another thread gunned down by Steven.

Just want to ask Vtec really engage at 4k? Sorry, I never own a vtec car before.

Lagi power, lagi best, lagi minyak sep.

V8 mah, V8 = valve 8

if we don't use any cam mah save even more?

But why proton wira 1.6 SOHC got 16 valves? Waja 4G18 SOHC also got 16 valve?

Actually V6 does not mean it's inline 6 cylinder. Its a misconception by alot of people. V6 means 3 piston is laid on the left \ and another 3 piston on right / . Both connected to the crankshaft on the bottom.

If what you're saying is true? those engineers should be set ablazed for designing a dumb and inefficient engine. low torque but high FC.

Nope. i was poor, I drove a Saga Megavalve SOHC with 12 valves.

So to conclude. You're saying, less valves, less power, will have High FC?

owh.. now I know, 4A-GELU is a high torque engine at low end. is soft turbo like those mini turbo sold here? If can put in my car to get high torque will be great.

How to improve our GB to have low FC? I thought Cast block is heavier than forged block? Because forged billet block can use higher ms grade material or can perform heat treatment to increase the material hardness? People keep telling me cast rims are heavy while forged rims are light. Now I'm confused. But if engine block is same, GB is same, weight of chasis is same, the head is different, that means the lower valve will still consume more fuel than higher valve right? How much difference are we talking? this is good info to stop people from buying cars with little quantity of valves.

wah, you're quite knowledgeable, can you recommend your pomen to me? May need his help to advice me whether my GB is suitable or not.
