Actually the surbo thing is not necessary, and the improvement can be neglected. the intake air tunnelling in will not have effect when it reaches the end of ur intake manifold. Air spiral cannot make a 90 degree turn fren, it will oni spiral up to the part just after ur TB. When going into the 4 individual piping at the end of the TB, it will not have anymore spiral effect. If you have a chance, take at look at the Toyota 20V intake manifold, its awesome, factory spec have a spiral intake piping, spiral directly towards the 4 TB hehe. For elantra, we have 1 TB supplying air to 4 ducts via a 90 degree angle, so no use using the spiral. Maybe you can try removing ur surbo and see the pick up got difference.
The best and most simple way to get more pickup power or improve FC is:
1. More air inside ur tyres, maybe pump 230kpa (this is wat i do), improve the FC too
2. Carry the less load as u can
3. Dun let the gearbox change gear auto mode, i use the lever to control when i want to change gear to overtake.
4. so far i feel shell gives the best mileage
5. make sure ur extractor is not leaking, elantra extractor prone to leaking
6. remove the factory secondary airbox (inside ur fender), air intake will travel much smoother.
7. Denso iridium plugs can offer up to extra 20km per full tank for my car
8. always use OEM plug wires, those thick no brand don't offer any power improvement, but FC bad too. Unless u take Nology or NGK, those offers power improvement but i am not sure FC got affected or not. But Nology wires dun match with iridium plugs.
9. dun overfill ur auto-oil, gearbox will be damn heavy.
10. bypass the TB coolant intake hose, in hot countries no advantage.
11. bypass the PCV valve hose from going back to the intake manifold.
12. get a high flow drop in filter
more advance technique for NA engines:
hydrogen mixture air intake
heated fuel rail
heated then cooled down air intake
1st n 2nd item can improve mileage average 50% but not easy to implement and scare jpj kacau cos its modifying combustion
3rd item is still in testing, dun know how much good it can do in real world, but in theory, it could improve at about 20% FC
