01/01/20   The lower picture on this listing is the factory industrial setup which we are imitating and improving upon. it is not the one you are buying here. Simply shows positioning as mounted on a 686

This is a very well built manifold. Is made to mount a turbo (TO4 pattern) on your IH 666, 686, 766, 886 and others if powered by the 360 ag version or the DT 360 truck engine, above the engine and under/inside the hood of your tractor. Will bolt onto and is port matched to the larger exhaust ports of the truck 360 head. We have enlarged the ports so that it will work on the larger ports found in the truck head and we have built a bolt on stack with the flange forward that holds the turbo to match the location of the original factory industrial set up.  It will bolt onto the ag 312 and 360 as well as the truck version. There is a picture posted of the factory built two piece cast version mounted on a tractor (in red paint). The factory version pictured in the gallery here (cast iron and bolted to the red engine w yellow background) is extremely rare and was seen only on Industrial power units and on certain log skidders. I have seen less than 12 of these in my 50 years of being around IH products and traveling widely. We had planned to build these from cast exactly like the one pictured here.  But decided to have them built here in Pa. We work with excellent machine shop owner that controls the quality, and we can custom build and incorporate improvements based on what customers want and need. This is a proven manifold and it will build HP.  This manifold is built from 2 blocks of steel. The runners are cut by CNC machine in each block before they are welded together, Built with heavy steel walls, properly located flanges and enough flow capacity to support 1000 plus hp if you can run a large enough turbo and fuel pump! 

Your choice on the vertical stack is included in the price here, is built as a bolt on attachment with your choice of a copy of the "original" with a support pad for the vertical elbo made to mount the turbo with the intake side back and the exhaust front as was the factory industrial setup. This setup puts the turbo in and above the valve cover with a TO-4 mounting bolt pattern. Adapters to go down to the #3 pattern are available. Another choice currently available is a verticle stack with more height than factory and this gives the ability to run a larger diameter intake housing and requires you to direct the exhaust on your own design. AND, we are now building a vertical bolt on piece that has the same positioning, angle and bolt pattern as you will find on a 1066 and other 400 series engines. This allows the use of less costly after market parts, for the turbo, the donut, the sealing rings and the vertical exhaust elbo. It has a built in pad to support the factory cast exhaust elbow and puts the exhaust vertical in front of the fuel tank, Depending on which tractor you have, you may find the need to notch or shorten the fuel tank to clear the exhaust stack. The cast turbo elbo and sealing rings as well as the "donut" between are available for approx $ 185.

 This setup will work on a farm tractor application and with proper turbo and fuel settings run from 125 HP to 150HP and still allow great engine durability!
If you are going to be running high horse power (175 and up) we do reccomend oil cooling jets be installed in the block to provide a margin of protection to the bottom of the pistons.

WE NOW BUILD A SIMILAR TURBO MANIFOLD SETUP FOR D-310, D-358 AND THE D-402.  ALSO HAVE PROTOTYPES SIMILAR TO  THIS MANIFOLD BEING TESTED ON Cummins 6BT and 5.9 for convenient under the hood location of exhaust systems on IH and AC tractors that have been repowered with the Cummins 6 B series. These are a great manifold for field use and for tractor pullers; can be found running up to 1500 HP
