i try to make this short, it is the fact that DOHC hardly get good torque by design, while SOHC will perform better in that area.
i owned a SOHC 12V G4EB3 engine car in 1.5L displacement and also a DOHC 16V SP4H engine in 1.6L displacement, both with almost the same mod except the later does not use synthetic oil and iridium plugs and 3" CAI compared with the previous one, my SOHC can tapao the DOHC in low end. one simple example is driving up and down my apartment car park.
anothe example is to achieve 0-100km/h test. the SOHC can achieve 11.2 secs but the DOHC needs 12 secs.
so in joining the bashing and proofing rally, i would say Campro (they named it, or maybe i shall say Gen2 engine) is just a plan vanilla DOHC 16V 1.6L displacement engine, AND READ ME LIPS CAREFULLY.... UNLESS IT IS PERFECTLY TUNED. (DISCLAIMER RESERVED).
so, there is nothing more to be argue here, its all about the fact of money. my SOHC cost me RM6XK++ while DOHC cost me RM5XK++.
if wanna talk about FC, DOHC give me better FC becoz its a MT, but SOHC ones also not bad. both cars in the margin of RM50 runs around 300-360km before the next pump.
if wanna talk about handling, SOHC car can tapao my DOHC car, my cornering plus steerling responsiveness and turning ratio can tapao the DOHC in any way.
if wanna talk about interior design, my SOHC also can tapao the DOHC in any aspect.
if wanna talk about safety, lagi no need to talk, my SOHC achieve 5 stars front, 4 stars rear under USA NCHTUSA (what-so-ever abbrv) while my DOHC can easily being dented using my right foot lean against.
if wanna talk about spacious, my SOHC although have a smaller size of car, but interior spaces is larger, at least to put my head as i m topped 180cm in height. i can easily rest my balls comfortable during a long drive using SOHC.
so, you might ask me, if DOHC sux my balls under my dig, what i buy the DOHC? well, there are numerous reasons:
1. the DOHC is cheap for 1.6L displacement engine.
2. the DOHC spare parts are easier to find
3. the DOHC gives me MT and better FC
4. the DOHC just take me from point A to point B, i never tend to do dyno to showcase or race at F1.
5. the DOHC makes me think i am Schumacher or Karanjit Singh although my balls are not up to that par.
SO, MY PERSONAL CONCLUSIONS ARE:
- THESE ARE MY OWN SHARING, USING MY OWN CARS, MY OWN TUNING, MY OWN BASHING, SO I DUN START A FLAME HERE. SO IF ANYONE WANTED TO COMPARE CARS OR ENGINE, YOU BETTER HAVE ALL OF THEM IN UR GARAGE, THEORY, BOOKS, STUDIES, CERTIFICATIONS OR EVEN YOUR DAD'S COMMENTS STILL AS NOT GOOD ENUF FOR LOOKING AT UR OWN BALLS UNDER YOUR PANTS.
- I DO NOT THINK THAT THERE IS A UNIVERSAL, 100% CUN GUIDE TO DETERMINE WHOS IS GOOD AND WHOS BAD
- I ALSO BELIEVE EVERY DECISION MADE OF OUR FELLOWS MEMBERS HERE ARE GIVEN JUDGEMENT AND JUSTIFICATION "ON THAT MOMENT" OF TIME BASED ON THE AMOUNT OF INFORMATION ON HAND, I ALSO REGRET TO DO THIS MOD THAT MOD AFTER SOME TIME, WHY? BECAUSE TIME PASSED, PEOPLE CHANGED, MY BALLS DIFFERENT
- FROM TIME TO TIME WE DRIVE IN DIFFERENT TRAFFIC CONDITIONS, DIFFERENT ROUTE, DIFFERENT EMOTIONS ON THE ROAD, SO THERE IS NO GOLDEN RULES THAT GOVERNS ALL OUR READINGS AND FEELINGS ARE CONSISTENT AND ROBOMATICALLY RECORDED, ITS ALL IN OUR HEAD AND OUR BRAINS.
SO FELLAS, I GUESS IT IS NOT THAT IMPORTANT ANYMORE TO ASK SOMEONE TO SHOW THEIR DYNO OR THEIR BALLS, IT MAKES NO POINTS AND NO ONE WILL BE HONOURED A GRAMMY OR NOBEL PRIZE AFTERALL, IF WE ARE CONSIDERING NEWBIES IN THIS FORUM OR NEWBIES TO CAR UNDERSTANDING, I GUESS THEY ALL HAVE THEIR OWN BALLS UNDER THEIR PANTS, WE DO NOT NEED TO MEASURE THEIR BALLS SIZE USING OUR MEASUREMENT TAPES, LET THEM DO THE JUSTIFICATION, END OF THE DAY THEY CAN'T BLAMED ANYONE AND NO ONE IS GOING TO HOLD THEIR BALLS IF THEY FALLS, RIGHT?
ok, i had written enough, my hands are tired and my brain is shutting down after read this crazy topic for over 20 pages long, i start to unconcious now, so you guys can bash me now...
