We started improving our airflow by gasket matching the intake and exhaust ports of the intake and the manifolds. There were some early issues nothing like the Ford 6. Although effort has been made to try to present accurate information this website, it can contain some opinion, conjecture, errors, mistakes and typos so use any information with that in mind and if in doubt research anything you do not understand or question. This combination allows for a hotter explosion that pushes the piston down with more force, creating more usable power. By removing weight from the crankshaft we were able to take the unbalanced condition of the rotating assembly down to less than 0.
The L56 is emissions controlled with and. Why do cranks break and blocks crack on the 6. These unbalanced forces multiply as engine speed increases and cause not only vibrations, but also crankshaft wobble that damages main bearings. We do offer quality pistons and rings and have lower compression available, sometimes they take longer as they are not a popular item. Once the critical features of the block and reciprocating assembly have been dimensionally optimized, the engines are assembled with the finest components available.
He had spent a lot of effort and money over the years getting it built up exactly like he wanted. All that nonsense is recommended by them when one simply needs to use a quality to keep the 6. This engine was designed to answer the horsepower and torque needs of current and future drivers, meet emission standards, and reliability. The 1992-1993 model years used a 6. Caution about Oversized Engine Boring When we build our 6. Read Note about this product.
Sadly, we have made many trips to the local scrap yard with loads of scrap blocks to prove it. The combination of the increased displacement and the addition of boost, resulted in a rather large horsepower increase compared to their 6. As long as the same fuel and turbo systems are used, I would say that the seat-of-your-pants performance of a 6. Website designed to be viewed with Microsoft Internet Explorer Version 4. Finally, we installed Fel-Pro 6.
Instead of buying a new Duramax replacement, Ted challenged me to build the most durable, smoothest running and efficient 6. The distributor injection pump controls both metering, via an internal , and high pressure fuel delivery to the fuel injectors via internal precision hydraulic pumps. The block is then bored and torque-plate honed to the optimum piston-to-bore clearance. The cylinder heads were the final components addressed in making the engine as durable as possible. This ensures that the decks are perpendicular to each other and 45 ° from a line passing through the crank and cam centerlines.
As an extra line of defense, we installed bronze coolant passage liners into each cylinder head. Airflow Efficiency Simplistically, all engines can be viewed as air pumps. In choosing which components and processes to use for this build, we sought those that would yield the strongest possible combinations to mitigate or eliminate these known weaknesses. I've run and seen many Chevy V8s with twin-turbos and N2O, etc. As the air transitions from component to component in the intake system and, then, out though the exhaust components, there are irregularities that disrupt and slow the flow through the engine.
To gain the increased displacement, the bore was increased to 4. The rest of the engine was built to pretty standard diesel specs. The higher compression that can be run safely without overheating and detonation then the better the efficiency and power output, the key is to keep things cool. The first decision we faced was which block we would use as the foundation of our engine. On the exhaust side, our biggest gain was a 15% increase in volume and a 26% increase in velocity at. For optimum efficiency, you need to get as much air as possible into and out of the engine as smoothly as possible. I am confident that our mission to build the most durable, smoothest running, and most efficient 6.
The new body style trucks ran a turbocharged 6. This extra heat energy forced through the turbo causes faster spool-up and more throttle responsiveness. Reconditioned rods with custom-coated Mahle pistons installed. By starting with a 6. The cost of such is prohibitive and even if you are doing a rebuild the prices are way over those of stock ratio pistons. This generation of engines faced the toughest emissions changes of any previous generation. For the day, these pumps were a good step forward but the engines remained pretty much a mechanical engine up until their replacement in 2001.
Like changing rocker arm ratio on one engine type can show power gains, do that on another type and you can loose power, float valves or even break something. We chose to use 1998 6. It has become clear to us that Mahle pistons are the best available and we use them exclusively. Another of the more common problems with both the 6. The General Motors light-truck 6.
