ah, gak harus klep ganda koq... tuh njess kagak klep ganda. lancer sebelum ini juga kagak klep ganda. galant hiu juga kagak klep ganda.. gak wajib mah klep ganda...
Ya bener juga bro. Ini ane copy dari Vtec temple asia :
R 20 sohc vs K 20 dohc:
Mungkin karena R20 lebih baru ya. Tapi emang dohc itu lebih mantap ya...I love dohc
So, R20A3 delivers pretty well on the dyno. But now its time for the acid test. Just how well does the R20A stack up against the old K20A from the 7Gen Accord 2.0 VTi on the dyno ?
According to Honda's data,
the R20A outperforms the old K20A in all three crucial areas of power, economy and emissions. In terms of max-power rating, the R20A delivers 156ps versus only 150ps from the old K20A - that 6ps is nothing to sneeze at. In terms of max-torque, the R20A delivers 19.3kgm or 0.3kgm more than the old K20A (which is rated at 19.0kgm). Again this 0.3kgm is quite significant. Added to this, Honda says the R20A has 7% better fuel economy while also meeting the stringent EURO-4 emissions regulations from Europe.
The power+torque comparison chart on the right is extracted from photos of the technical presentation given by the Honda R&D engineers during the media launch event. This chart is a direct comparison of the power and torque delivery curves for the R20A and the K20A. It shows that the power delivery of the R20A is quite significantly better than the old K20A as it delivers more power/torque across the whole rpm range. The midrange of the R20A is especially superior to the K20A, thanks to the dual-runner intake manifold. Then overturning the traditional relationship between an SOHC and a DOHC engine, the R20A also delivers significantly more power than the old K20A in the top-end, from just after 5,000rpm till the redline (which remains the same at 6,800rpm).
