The below suggestions are the best way to safely improve the power and torque output of our Montys regardless of model (2.5 or 3.2)
1. Install a piggyback computer to change the fuel mapping, ignition timing, and boost flow of the ECU (Emanage, Haltech, or Unichip) what kind of piggy back our rigs have 3 diffrent types of piggy back system (commonrail, injectors and ecu)?
2. Snap on a bigger front mounted air to air intercooler (bar and fin design if possible). Dont install too big intercoolers!! They may look angas and cool but surely inappropriate for our application. Pressure drop is one thing we want to prevent in upgrading our intercoolers. No need to change the original pipings. Just make sure the inlet and outlet of the intercooler will meet the original location of the pipings. You can save roughly 12k if we dont have the pipings fabricated (mandrel bent) Intercooler and not a turbo kit, but still kung hindi tugma problema pa din? Doind this with out the proper setting in you electonic system is still a problem.
3. Freer flowing panel air filter. I strongly suggest not to install cone type aftermarket filters since it would suck hot air off the engine bay.Ito malamang sencor problem and kasunod.
4. Get an alcohol injection kit. (Devil's own, Aem etc).. With this one we can safely raise the boost level of the turbo not to mention clean up the combustion internals. Mother nature friendly =)
5. No need to change the pipings of our exhaust system just the muffler. I think the OEM diameter of our exhaust system is 2.5 inches. Good enough since CRDI engines by nature isnt rev happy. They all cooked up at roughly around 4.5k rpm. At that range, we arent really making a lot of smoke so no need to increase the diameter. Howver, if we cant help ourselves the biggest we could install and not lose a lot of torque production at low rpms is 2.75 inches what types of metal to be use?
6. Good fully syn oil like Royal Purple, Motul excess, Castrol Edge among others. Motul's 300v is too expensive for a lazy revving diesel engine.
7. 1 bottle of Bioactive per 50 liters of diesel. Take my word on this one... =)
8. Lastly but the most important of all, an accurate dynamometer like the one Carlos Gono has in Autoplus and Tommy Teng's flywheel units in Autoteknika. Autoplus would have much lower read out since it measures the power through the wheels which is more accurate as weight and inertia are being factored in the testing.
hmmmm.. ano pa ba?
A good tuner of course. Pacho and Tommy are two of the most famous and arguably the best tuners in the metro. Is Ferman doing the dyno tuning at Speedlab?
With these modifications at hand, Im confident I would be able to tune the 4m41 up to 200++ hp and approximately 450nm at the crank. Not to mention better FC and cleaner emissions
