QUOTE(peris @ Aug 1 2008, 10:34 AM) is't..lol..my satria using 16' rims...so how i wanna know how fast i drive then? i think rims is not an issue (unless you take weight into account) but the tire radius.i'm a good citizen..dun wan to be caught by police http://swatt.j.porter.name/tech-center/tool/tire-calculator compare your stock tire with the new ones that you are using. then you can see the difference in size. |

QUOTE(nimrod2 @ Aug 1 2008, 10:45 AM) i think its more like urban legend. Depends the 3.0L accord or BMW how big Gear Box.. Gear radius/diameter is main course the RPM.haha i think for high capacity engines, its possible to have lower rpms. for a 3.0L accord or bmw, i think the revs is around 2.5k or lower. If 3.0L engine go with gen2 gear box.. it will same will go thru 3k rpm, 110kmh. This post has been edited by LeVis_Jeans: Aug 1 2008, 11:25 AM |

Kenari Auto
110km/h at 3.6K RPM. BTW, for auto user without lockup clutch, the RPM can vary. For example, when u release the trottle, ur RPM will drop faster compared to your speed. |

QUOTE(nimrod2 @ Aug 1 2008, 12:07 PM) I am not comparing auto transmission with manual transmission. What I am saying is, if your auto transmission does not have lock up clutch, your RPM to KM/h ratio will not be fixed 100% of the time, since your gearbox is always slipping against the engine, through the torque convertor. |

wow, from the readings, smaller cc auto cars tends to have higher rpm readings @ 110km/h.
i feel like the fc will increase when the rpm > 3000 anyone knows for hyundai getz 1.4? |

QUOTE(sleepwalker @ Aug 1 2008, 09:15 AM) The lower the RPM, the more efficient the engine and hence better fuel consumption. However, it cannot be used as a comparison as the engine itself would be the main factor in the calculation of fuel consumption and not the gear ratio. Furthermore, there are no aftermarket parts to change gear ratios (too much work to be cost effective) and hence it is seldom a factor in the calculation of FC. there are plenty of aftermarket 1-5 gear ratio and final drive. They even can custom made for you if your pocket is deep enough.The gear ratio is only effective in calculation if you are comparing 2 cars of the same make, same engine but different gear ratios. But you are right, the RPM at certain speed is all affected by the gear ratio and final drive. |

QUOTE(Cahill @ Aug 1 2008, 12:30 PM) there are plenty of aftermarket 1-5 gear ratio and final drive. They even can custom made for you if your pocket is deep enough. No there isn't and custom made ones are not considered as plenty in the market. Plenty in the market means you can walk into BROTHERS and say.. "I'd have that ratio mixed with this one and put them all into the gearbox while I go next door mamak for a teh tarik". That I would consider as plenty in the market.But you are right, the RPM at certain speed is all affected by the gear ratio and final drive. Gear cogs are not something you find on the shelf in every shop. It is good info to have about RPM per KM/H but that is all.. just nice to have. It is not something we can change easily or even make use of in our daily course of driving and modding. It takes some serious 'moolah' to get it done and not worth it if it is just for FC.

Satria Neo 1.6(A) 110km/h = 3000rpm highest gear(4th)
so if the readings of the speedo are not affected by rim size, means say if 13" rims, 110km/h real speed,110km/h speedo speed, 3000rpm..... n then use 16" rims 130km/h real speed, 110km/h speedo speed, 3000rpm.. means use bigger rims can make your car quieter?? |

so lets say im using campro now n using this INVECSII (i think) gearbox from mitsu...
izzit possible to change to other gearbox? lets say from mitsu also, izzit possible? btw, i still dun get it, in campro, got engine braking concept rite, the one which will lower ur gear when u going downhill.. will it consume petrol more? lets say i drive at 90km/h with around 2.6k rpm, n suddenly the engine braking activated when going downhill without pressing the pedal.. so should i press the pedal more lets say 110km/h at 3k rpm so the engine braking will not activated or juz let the engine braking lower the gear and make it whooping at around 4k rpm at 90km/h without pressing the pedal which one consume less fuel? sori if im talking crap here |
