Twists and turns to get a six-cylinder large cut worm type intake manifold, Subaru Connecting Rod the installed power after feeling improved, especially at low speeds, the throttle responsive than before, while at the high-end speed, the follow-up with plenty of power many, such as 5-speed 80KM / H, the power and then speed much higher than before. His reason is that the original car modification at right angles to the intake manifold 6 right angle into the trachea by the mains line, and 1,6-cylinder intake manifold than 2,3,4,5-cylinder intake manifold for a long period, resulting in 1,6-cylinder supply shortage, inadequate combustion, reducing 1,6-cylinder power output. Split-off of TX 6-cylinder head will notice 1,6 cylinder significantly more than the other cylinder coke. This is the original car design problems. 143KW large cut of the intake manifold into a snail type, 1 to 6-cylinder pipe length is basically the same, so each cylinder gas flow equalization, each vacuum degree of vacuum is relatively balanced. Improve the deficiencies before too long causing 1,6-cylinder intake manifold intake. Here are some of his experience I hope to help the riders prepared to do a similar conversion.
6-cylinder Grand Cherokee modified cochlear intake manifold power increase [chart]
The main difference between the North after consulting Kyrgyzstan technician, 127KW and 143KW engine intake manifold of the engine is aimed at fully play 1,6-cylinder power to change others as vacuum, computer parameters and other details are not for power. Therefore, modification may not have to rewrite your computer. Recommendation 6-cylinder TX who have the opportunity to change.
Changes accessories are as follows: intake manifold; power steering pump, power steering pump bracket (to 6-cylinder automatic transmission, is the same as if the carburetor, forgotten), E36 Coilovers tensioning screw, tensioner (original idler to this use); air temperature sensor, each vacuum mouth (former Remove the intake manifold, in turn correspond to be installed, and some require drilling tapping), pay attention to the thickness of the tube must be installed in accordance with the original, in order to avoid a vacuum degree changes resulting sensor signal error.
We care about improving the intake manifold after the change in fuel consumption, fuel consumption following talk about the latest situation. These days ran Mongolia trip, round trip around 1600KM, two boxes of consumption statistics, as follows:
The first box: starting 90 # fill the oil tank (plus plus to not far behind the same), Beijing - Badaling Expressway - Jing Zhang speed - high-speed Beijing-Tibet .... Hohhot nearby service area refueling to the full box, 310 yuan, 93 # oil Price 4.89, approximately 63.4L, this time driving 445KM, before adding the calculated average fuel consumption of 90 # 14.25L / 100KM; road: full speed, uphill for many, the Badaling section of slow moving, low high to overtake; Badaling carts after getting less, but still uphill, speed of 110 to 140 dollars.
The second box: Dalateqi surrounding events, no traffic jams, state and provincial roads, highways accounted for more than 85%, adhere to the Ordos fill, 305 yuan, 90 # Oil Price 4.59, approximately 66.5L, this time driving 502KM, before adding the calculated average fuel consumption is about 93 # 13.24L / 100KM.
Note: there is no significant change in fuel consumption, with essentially the same before conversion. Not all open air, not to fuel-efficient, it is cool temperatures.
