Hi all, I'm Alberto, from Italy.
Here I'd like to post some works I made/will make in Automation; the first one I present you is the Intruder in its Sport version, hope you like it.
It's a small hatchback with a sporty look that blinks the eye to the environment; it has a small an nimble 900cc 4 cylinders turbo engine that produces 80HP with a pretty high torque of 135Nm.

I am really impressed with that although the RON numbers are way off you may need some fine tuning there but still great work

you really should rework the engine. The economy is terrible. You should try lowering the boost, run the engine less rich, up the compression and set the ignition timing earlier. Try fiddling around a bit until you get to around 300 g/kWh or lower, and remember to get as close to the RON you use as you can (so if you run on 95 RON fuel, try to get as close as possible to that).

Also, SPFI is outdated. Go for DI (or MPFI, If you'd rather go for low costs and weight)

and try DOHC as well and its all about ignition timing and compression and fuel mixture try and make it say what Tom said using 95 Octane make sure you can hit Fuel Octane (RON): 95.0 spot on

Revised version, with more or less same power but more economy and efficiency

bit more work and it should be absolutely perfect I always try and hit the exact RON number when I am building engines I use to be terrible at it and now I have got the skill to match it exactly

A good restyling also for the body, to accomodate a better grill for the intercooler and better tail lights. Hope you like it.

Here it is my other work...it was ready from some days...but tonight, using your advices, I adjusted it a bit. I present you the Virago Coupè: a good looking coupè, with a fast twin turbo V8...of course, economy and environment here are not the first priority, but still I have to say it's not bad. Hope you like it.
