Are were any one who know where I can find a picture like this one:
But for the engine in the ZX 2.0i 16v, 155hp (xu 10 j4d/z).

Dont have one, but I will put it on a dyno once and then I should have one

This is a graph which is included in the technical manual of this type of engine. |

Hmm I should have known that 
But the power 'boost' around 4000rpm is not really visible. |

Tanks for the picture. Does anyone have the transmission ratio for the gears and the finaldrive for the gearbox in ZX 2.0i 16v? Magnus |

All that kind of info is in this file: http://www.zx16v.net/temp/XU10J4RFY.rar The picture posted is also from this file, it is in Dutch, but that is better than French |

Thanks for the manual. I didn't find the gear ratios there, but I found them here http://cx.podolsk.ru/xm/docum/haynes_zx/zx-07a.pdf Magnus |

Have you tested your car on the Dyno yet? I just bought a G-tech Pro, a device used to measure the cars performance. With the G-tech I measured the horsepower to around 135 HP at the wheels on my ZX 2.0i 16V, year 1993. And if I assume it is a 15% power lost in the gearbox/transmission it mean the car still have all the original 155 HP. I also used the device to measure 0-96 km/h times and 1/4 mile times. I got, two persons in the car, 0-96 km/h around 8.7 - 8.9 sec and 1/4 mile just under 17 sec. I think the times seem to be ok. I looked in a catalog from Citroen from 1992 or 1993 where it stood 0-100 km/h 8.5 sec, 1/4 mile 16 sec. I think those times seemed a bit optimistic. It also stood that the top speed is 220 km/h but doing some calculations with gear ratios, engine max revolution and wheel radius it turns out that the top speed should be something like 210 km/h depending on the wheel size. I did get a theoretical top speed to 211 km/h with my 195/65 R15 tires, with the original 195/55 R195 I believe the theoretical top speed should be 205-210 km/h. Any one else who have clocked their ZX 2.0i 16v? /Magnus |

A G-Tech rules 
No dyno yet, but it seems that we'll have one sooner or later with CitroSport. I did test the topspeed at the autobahn and it got to 216 kp/h at the GPS receiver. On the clock you'll get about 225 kp/h. |

Aha, I see. Since it is a long way to Autobahn from Sweden, I have never tested the real top speed. I believe the wheel radius I used in my calculations may have been a bit small. Since the radius gets a bit smaller when the wheel is mounted on the car thanks to it gets deflected I may have measured the radius a bit to small. /Magnus |

Oh btw that 216 kp/h was with a 195/50/15 tire, standard size is 195/55/15 so it should go even faster because the radius is bigger. |

Have done some more calculations now, checked in a book for correct rolling radius. Found out that the radius for the 195/65R15 was 30.8 cm, 195/55R15 28.9 cm and the 190/55R15 28.5 cm. With the new calculations I found out that the top speed for the 195/55R15 and the 195/50R15 tires both have a top speed at around 216 km/h but the bigger 195/65R15 only hade a top speed at 210 km/h. This may sound strange but weighing in the road resistance, engine power (the power curve), wind resistance and gear ratios you will find out this. Now my calculations are not 100% correct since I don't have the right wind and rolling resistance coefficients and not the correct power loos in the transmission. But I believe the values are realistic. /Magnus |
