只能說耐用吧....
強的應該是EW10J4S
不過還是沒有辦法像日系車一樣
突破一公升壓榨出100匹馬力的技術阿~~
(難道是為了給車友自己進化的空間???)
The improvement ( allow me to use this word coz J4 vs. J4S is relatively small modifications) is only as list down:
1. 10000RPM balanced crankshaft.
2. Variable Time control on the in-port side.
3. Remodify Mainfold for high Revs air sump. ( not sure if the mainfold value have been enlarged as well)
I recall that even the compression ratio is same as 10.8 and the cutoff line for J4S is 8000, much lower than the F20C 11.6,
90Hp per liter is really a impressive num compare to Euro Mkt 2liter NA cars.
Ford Fiesta ST is rating as the very sweet pocket rocket in the Euro mkt, net it only got 167hp, 13 HP lower than the EW10J4S,
The only Pocket Rocket who beat this is the EK9 Si only sold in the UK, 220Hp, but this is with the I-Vtec engineer, which not only control the Variable time but also the lift of the Value. In my opinion, when it come to red line (7~8000 above), the lift level of the value should help more HP gain vs. the fixed variable timing.
I believe that with the upgraded Piston to raise the Compression ratio to >11, and with modified the head with big in-port value, there is no way that EW10J4S can't pass 200 HP and enter to the Famous Hall together with Honda & Ferrari of the 100 HP per liter (NA).
Ps: Can't input chinese now, K |
