Sojo Automotive....... the TD42 one stop shop

Ok so the time has finally arrived where I can make this official.
For a while now I have been doing some mods on the TD42 engines to get them away from the “donkey status” and after MANY tests, trials and using different settings on anything power related on these engines I finally have a recipe that is working great.
So with the permission of Ian du Toit, I could use his TD42 pickup to see what exactly we are gaining on these modifications.
I did n dyno run on his pickup stock standard without ever being fiddled with, I then installed the famous Viper 3” exhaust and did another dyno run to see what the gains are.
In a nutshell, we gained the following results at the rear wheels. Please note that the dyno runs were done at SAC Centurion and there are not calculated figures here……its raw power on the wheels.
Standard power: 70Kw @ 3,500rpm & 236Nm @ 2,000rpm
Exhaust only: 78kw @ 3,500 & 250Nm @ 2,500 (Gained 11% Kw & 6% Torque)
Exhaust and tuning: 114Kw @ 3,000rpm & 376Nm @ 2,500rpm (Gained 63% Kw & 60% Torque)
The kw and torque curves really speak for themselves and there are other very important benefits from this.
1. The torque curve is very flat and you now have maximum torque between 2,000 and 3,000rpm where before it was only between 2,000 and 2,500rpm. This gives you a more usable torque than before. You also now have 129 torque more on 1,500rpm which is really ideal.
2. The EGT’s run very stable and very safe. The alarm is set to 680deg pre turbo but I could not even get to 650deg under extreme loads and 520deg was the highest recorded temp on the dyno.
3. Overall the drivability of the vehicle has changed completely. You can now actually enjoy driving it!
What does it cost and what do you get for your money?
The cost for this conversion works out around R24,000 and for that, you get the following:
1. A Madman EMS2 with EGT, water temp and water level monitoring.
2. A 3” stainless free flow exhaust built by Viper exhaust in Kempton Park from the turbo right to the back.
3. Die diesel pump gets a boost compensator and is calibrated to the correct settings to give the optimum amount of fuel and to advance the timing a bit better.
4. Injector pressures are pushed up a bit to give better atomization and better combustion.
5. The turbo boost is pushed up from 0.4 bar to 0.8 bar
6. Lots of tuning……
Costs not covered by this conversion are things like a worn out diesel pump and/or injectors, damaged turbo or anything else not mentioned in the list above.
Doing a complete pump overhaul and installing new injector tips can push the prices up by another R6,000 to R7,000 but this does not happen often.
Please send me a PM if you are interested
