Re: Jeep OM642 CRD Performance Mod's
The engine won't hold to 500 HP. The rods and pistons won't hold that much power. 400 HP would be the top of what a stock engine could handle, but you will be pushing the limit of the stock head bolts. The stock CP3 injection pump won't get you past 350 so unless you have gotten farther than me on using a upgraded CP3 than I wouldn't worry about it. Currently one on makes a turbo to get over 350 HP. I sell a turbo kit to get you to 350 and working on a VGT turbo to get to 400 HP. If you go a non VGT turbo you could go higher, but I don't know of anyone with much experience with tuning those. I have designed a 400+ twin turbo setup, but don't have much time or money to devout to that project. I don't see the engine living that long. The GTB2260VKLR turbo will work, but you need to use a modified mount that goes with that turbo or make your own.
I have played quite a bit with methanol injection and it will had some, but its not going to knock your socks off. I only use if you have run out of fuel and need a tiny bit more to get a small amount of power, I call it a band aid power adder as it just helps mask other areas that need to be addressed.
