We did not include a dyno printout, because essentially, we got no increase or decrease in power from the unit. According to Mitsubishi, the new cylinder dimensions contribute to a free-revving character max power at 6500 rpm , linear power delivery and wide torque curve. The vehicle was then placed on the dyno before modifying the exhaust, and a baseline run performed. The 4B11T offers a broader torque curve, producing more torque than the 4G63 at all engine speeds, helped by the engine's and design, both measure 86 mm 3. It is not a guide to its place within that family, nor is it a guide to the capacity of the engine. Since these usually run quite rich and low on ignition timing, these will be safe to leave untouched. We did not include a dyno printout, because essentially, we got no increase or decrease in power from the unit.
Below are also some photos of the kit fitted to the vehicle, although better photos will be provided soon as well. The average air intake temperature with this system was 36 degrees, which we can take as the factory average as well. The question would be which variable valve actuation system is the most efficient: This one, the fiat multi-air system or the complete camless system currently developed by Valéo? Suspension was very soft, and brakes felt good. Note that the origonal test vehicle utilised a 63. We replaced the factory piping, with a new 90 degree silicon elbow which utilises smooth piping. We will for our purposes, only be modifying the high octane maps, leaving all low octane maps factory for added safety.
For this reason, they removed the former closely-coupled catalyst in the exhaust manifold in the Outlander and realized a better environmental. We also took the opportunity, utilising EvoScan data logging technology, to record the average air intake temperature from each test. What is interesting, is that in comparison to the overly rich tune on the 4B12 engines, which leaned out with the fitment of the very same cold air induction kits, the 4B11 motor richened up instead. For the front and rear engine mounts, a custom-tuned insulator helps control both idle vibration and acceleration shock. This engine was used in the Super DeLuxe and.
A much higher achievable overdrive ensures good fuel economy and lower engine speed for highway cruising. Rear exhaust engine layout In order to reduce exhaust emission, Mitsubishi adopted a rear exhaust layout. Hopefully this will clear up some confusion people have with the results from the dyno print outs. Is there the same potential for diesel engines? Flywheel casting numbers So if you are trying to identify an engine, call you machine shop and have them check it out for you. Peak torque was produced at 4250 rpm and tapered off This can be seen on future graphs. Below our our plans in rough order and as we progress through them — we will update this page with data sheets, photos and dyno print outs etc. This is a mechanical hub connection to the wheels and whilst the numbers may be slightly higher over a normal roller dyno, the gains are 100% confirmed between runs with no variations to worry about other than mild temperature variations which we will be attempting to minimise.
With our ability to re-flash, these problems will be easily solved as we change the appropriate maps to give us more flexibility. We explain this, by the sheer fact the stock air intake box set-up, is quite restrictive in factory form. To lower vibration, Mitsubishi used a 4-point axis system with cylindrical engine mounts on the left and right sides. So there is a silver lining in every cloud, this testing allowed us to identify several key weaknesses in the vehicle, and confirmed to us that these vehicles definitely prefer the larger bore systems. We believe this is due to the difference in the engine capacity with the larger engine pulling a greater volume of air with the less restrictive air intake system compared to the smaller 2.
We anticipate a lot of response and some great results out of this engine. A revised turbocharger offers up to 20-percent quicker response at lower engine speeds compared to previous 4G63. Suspension was very soft, and brakes felt good. Together, they cited information from. We recommend that for those using the stock system, that they definitely get the Ralliart Air Intake with the larger scoop to maximise airflow into the air cleaner box. From a performance stand point, the EvoX cams moves the powerband higher at the extreme rpm say 6500rpm as opposed to the 4B12 cams since the valve overlap is 41 and 30 respectively.
I'll dig a bit deeper. In particular they reduced the friction when the vehicle is warming up which contributed to reduce furthermore the fuel consumption. Interesting to note is that from 4250 rpm onwards, the gains remained fairly consistent. Below is a picture of the rear muffler. The size of the set-up is virtually fixed in the amount of air it can pull at one time. A silent chain is used to drive the.
On the left side where the transmission is, a similar lightweight, high-rigidity plate bracket made of steel helps reduce gear noise. The twin tip system has a much smaller muffler design for greater noise levels and has the Mitsubishi Ralliart Lancer spec centre to centre clearances on the rear tips. What is more important, is in this example, the valve lift in the 4B12 is 15 degrees longer whilst it also maintains idle stability. A wide variety of mitsubishi 4b12 engine parts options are available to you, such as free samples. Your request will be sent —without obligation- to 149 Dutch car dismantling companies. The results were impressive, with an average of 5hp gain at the wheels, improved torque across the board, and more importantly we started to smooth out the horrible dips and dives in the power curve. If there is any quality problem on approval.
