1720 Ford SSS Turbo Installation

[TBartlett1]

I just finished the installation of a Garrett GT1752 wastegated turbo on my Ford 1720 SSS that I purchased at a swap meet for $35.

The turbo is off a SAAB 2. 0 or 2. 3

The exaust looks cleaner but don't know about power yet.

Does anyone know how to increase the fuel?

The repair manual does not cover the injection pump.

The injection pump is a Diesel KIKI K. K #104294-3120

The engine is a 3cyl 91cuin (1. 5 liter)

I'm looking for 5~10hp for running my 60 snowblower, at times it just doesn't have enough!

I will be doing a dyno run using my 25KW pto generator to measure power with & without turbo.

Currently it is running 3~3-1/5 psi boost.

Thanks Tim

Neat project!

I would guess that if your only at 3-3. 5 psi there is room for a bit more fuel!

I can't seem to find info on the 1720 but it's smaller cousin the 1520 (also a Shibaura engine) has a 23:1 compression ratio. I would guess yours is similar so it doesn't leave much room for boost. I wouldn't advise letting it get much over 5-7 psi.

I agree 5~8 psi is my goal.

This turbo was set for 8psi boost in the SAAB application but actuator was removed to simplify installation and the gate is currently wired closed.

Hopefully someone knows what I need to do for more fuel, when that happens I will reinstall the waste gate actuator.

what are you using to dump that 25 kw in while your dynoing it, do you have resistance heaters in a water tank ?

 

[TBartlett1]

I have a 7. 5kw heater with fan that has (3) 2500 watt elements. I rewired it so I can select 2500, 5000 or 7500 watts. I also have a 3hp planer & 3hp shaper that I can use to load the generator.

Well I turned the fuel & speed up the other day on my 1720 Ford, what a beast it now is!!

I put my 60” snow blower on and gave it a HOT SUPPER in wet snow, absolutely amazing.

It now throws wet snow like it was light powder 40 plus feet but when really pushed I get black exhaust but the boost still topped out at 3 psi??

After much pondering I went out the next morning and checked my boost gauge. Defective gauge 3 psi was the highest reading regardless of pressure applied.

Found another gauge and decided to use my pto generator to do another load test, the problem now is that I can't find enough electrical load to drop speed below 540 rpm. Boost is now 4 psi but that is not fully loaded.

Time for a run down the road, boost will peak at 7~8 briefly as it accelerates but drops when it hit's the governor @ 2900.

Black smoke indicates lack of air so I guess a smaller turbo or possibly twins will be going on at a later date.

Good deal!

Did you plumb the WG back in yet?

I won't hook it up untill the boost gets ovet 8~10psi.
