Suzuki Alto Works 2016
Discussion
Unfortunately no mapping today, just a power run to see what she's doing.
So yeah as expected, the boost is forced down (which lowers the torque) to keep it under 64hp, even although it made 68hp. What's a few hp on a dyno though? Not sure what caused the sudden dip between 5500 and 6000.
Major problem with the standard intercooler, inlet temps getting to 57 degrees c at some points! I have already got a new intercooler planned though which I will be fitting shortly.
If it can hold that torque (Which I know it can as I've seen it blogged on a few Japanese websites), it should be good for about 90-95hp. The injectors and fuel pump have the capacity which is a good start.
So plans are Exhaust, new intercooler and a live remap to get it just right. There's probably not much point trying to get this engine past 100hp, it'll be too difficult I think seeing as it's designed for economy and efficiency.
Had the car weighted too, 750Kg with a full tank

How's it going? Did you get this mapped?
Not yet, I have a base to build from waiting to get loaded. I can't do anything until my intercooler arrives because of the inlet temps. would be a waste of time to start doing anything before I do everything else 
It's a custom air-water-air cooler.

Again, this is such a cool wee car. Could you give a bit more info on your supercharged 106 diesel?
Yeah so I supercharged the 106 diesel for racing during 2019 just to prove if I could to it reliably.So without the supercharger, it made 70hp, with the supercharge it made... 70hp. It moved where the peak hp occurred by 2000rpm! Which was a massive 70ft.lb torque increase at 2200rpm. Useless for track though hahaha!
So for this year, it's getting a turbocharger, so I'll be much closer to 120hp with it. I'm making the Peugeot competitive this year.

Haha, that's pretty interesting! Do you reckon the fuel pump was maxed out, or does it have an upgraded pump?So without the supercharger, it made 70hp, with the supercharge it made... 70hp.

I used to have a 106 diesel and always wondered about 'charging it.

No, the charger was too small. I used to have a 106 diesel and always wondered about 'charging it.

The standard Bosch 8mm pump is probably good for about 100hp.
The big problem is space, there's simply no room for a bigger supercharger in there without removing the alternator (which I had to do) or fitting a really long shaft to reach a bigger charger.
I ran no intercooler either, inlet temps regularly went over 100 degress c. oops haha.
Well... okay, might have one small modification lined up IF i can make it fit, it should be super effective.
Of course as you can see, it's a Lotus charge cooler from an Esprit. The angles of the inlet and outlet are about right, and I reckon for road use even just filling it with water and not circulating it would be enough to keep the inlet temps in check. I do plan to fit a small pump and have some water circulating.
It's just finding the time to do it, I've got more sprints coming up and need to sort out my Peugeot reliability issues.

Interesting!
Good to see this car is going. I still hanker after one of these. How easy is it to get parts form them? Last time I had a JDM I ended up shipping in parts from this lot:

Haha I suspect its going to run for a long time as well.Good to see this car is going. I still hanker after one of these. How easy is it to get parts form them? Last time I had a JDM I ended up shipping in parts from this lot:

Don't know, haven't needed any parts yet, everything is still as it left the factory in 2016. Even the brake pads still have plenty on them.
From a glance it looks like it shares lots with Suzuki's here (shock) typical Suzuki really.
Brakes etc look identical to the Ignis sport, suspect the struts are very similar as well although I've not looked at the part number.
Using oil filter for a cappuccino, although the filters seem to be the same size across most small Suzuki engines.
One thing I do need, is an interior cabin filter because it's starting to turn black! I'll probably end up just cutting down one from another model though.
I've been side tracked a bit by my new Jimny as well.
