QUOTE(imperialrealcs @ Oct 14 2008, 04:25 AM) so u look down on other car without vtec eh? besides, ivtec again, works differently than the conventional vtec.. ivtec is more like cvvt, juz like newer version of mivecs.. juz pray u dont use ur vtec L15A to race satria mivec out there or u shat brix lol AFAIK, i-Vtec can varies the lift infinitely instead of 2-stages as in Vtec by using solenoids to control the valve rather than lobes on cams. Because of this, you get better efficiency and power, but loose the 'feeling' of power surge when Vtec open.  |

QUOTE(ZeroSP @ Oct 14 2008, 04:24 PM) Believe it or not, Proton claims that Waja CPS 125PS, but yet on the road they still lose to 110PS L15A. Paultan already dyno a CPS Gen.2 at got about 109whp in a hot afternoon.  This post has been edited by sphiroth: Oct 14 2008, 05:01 PM |

QUOTE(imperialrealcs @ Oct 14 2008, 05:21 PM) so how exactly the cps changed between "2 set of fixed valve timing" ? via different 2 fixed cam lobe in a single camshaft? how was that different than that in b16 VTEC? what a backfire statement waja cps weights 1235KG and 125bhp while city weight only 1090KG and 110bhp even the super b16 VTEC claimed 160bhp lost to 122bhp lotus elise thats already on-crank bhp for honda city.. after all the transmission loss, i wonder how the L15A will win  I wonder if his engineer friend is really an engineer..   |

QUOTE(ZeroSP @ Oct 15 2008, 12:25 AM) Ok... Since I am making so much noob statement here... I just don't know how to explain then... Anyway, thanks sphiroth for the link. And to imperial, I have to respect whatever you say.. But what I test is just what I say bout the CPS vs L15, and City dun have that much transmission lost because don't have the torque converter... So forgive me everyone if you all cant take my noob statement. Nevermind, we all make mistake. But if you're not sure about something, better put 'AFAIK' or 'IMHO' before you're statement. |

QUOTE(Lim Ling Yang @ Oct 16 2008, 10:29 AM) Lol that 7 speed is fake one haha. Don't say 'fake' la.. use 'virtual' instead. QUOTE(greedy5513 @ Oct 16 2008, 10:54 AM) A continuously variable transmission (CVT) is a transmission which can change steplessly through an infinite number of effective gear ratios.. wikipedia. you want speed and you want to save fuel? go play your need for speed or any racing game. 又要马儿跑得好，又不给马吃草。 want horse run fast, but don let horse eat grass how to give u horsepower? no horsepower no speed. Can. Give your horse a dose of steroids (NOS). But beware that your horse may died of heart attack (blown engine). |
