An HX35 on that 3 litre engine will have very little below 3,000rpm which will be hot and somkey on a F150. I think I sized up a 300hp compound set for a guy on a UK forum which was to deliver strong and clean low end boost. I'll see if I can find that later.Agree with you, Atg. I got a complete 99 turbo diesel car for $2k. Runs great-rusty body. It's going into a 97 F150 4x4. These 3L 4v motors are awesome. So much smoother than a cummins (which by nature has virtually uncontrollable low RPM torque spikes!) and is actually made for a car/light truck-not a bread truck or tractor. It will have an earlier om603 mechanical 7.5mm Dieselmeken super pump and a Holset Hx35w turbo all setup for 300HP. Will be single wire 12v and no computer! My big challenges will be instrumentation/tranny adapter/plumbing/engine mounts/exhaust. Bendtsens will be supplying my adapter so I can use my E4OD with a standalone tcu and a suitable torque converter that Bendtsens will also most likely supply. Hopefully I'll be getting the thirsty boat anchor (5.4) out of the truck this winter and get a build thread started. Any experience out there with om606.962 swaps will be welcomed input. The Europeans and a few North Americans over at the STD site have been a magnificent help getting this project off the ground.
They are using absolutely tiny turbos as they have to meet emissions targets at all times. That's why they need to bypass them.Interestingly, they recommend using small turbos with bypass of both compressor and turbine of small turbo at higher rpm. So it is a compound at low rpm only. This is for light passenger vehicles.
