Guys, I finally put my original 66 hp Uno Fire Flex 1.0 8v on the dynamometer with the changes I made to it. Remembering that the engine's internal part is completely original and tired; I never disassembled the engine or even the cylinder head for a good overhaul. Aspirated engines require a lot of investment, especially in terms of volume, rate and cylinder head. I'm going to make the basic changes to my Fire 1.4 8v that I have here at home. In it, I'm going to mess with the engine's compression rate, which in aspirated engines the higher the better, improve the flow by optimizing the ducts and larger camshafts. In the block part, I'm going to use the pistons from the Fire 1.3 with a 1.4 crankshaft with more stroke to have more volume. In other words, then we'll have an idea of ​​what a Fire 1.3 is like when it's almost 1.4 in the aspirated phase, which is the normal operation of the engine. My Uno came out really well, even though the remap that had been done is working perfectly, but the tuner himself said at the time that I needed to leave the car there with him to do exactly what was done. It really changed a lot in driving the car, because the Uno is very light, it really packs a lot even though it has a small displacement and does not have a turbo. Many people talk about turbocharging, and yes, for a 1.0 8v engine, what really makes it generate good power is turbocharging. But if you have a car and want to improve its performance, doing everything I did, which is nothing extraordinary, will certainly guarantee you a result much better than the original. I'm going to get an original Fire 1.0 8v in good condition to do the calibration to have the original reference for mine, which I already did a test against a 2012 Palio economy that already has 75 original hp and it was simply boring, because my Uno beat more than 3 cars up to 140 and when I went over 160 I lost sight of the Palio. So, to emphasize, the purpose of these changes is to change exactly where the automaker caps the car to meet pollutant emission standards. And there is also the possibility of changing the internal parts of the engine, but the investment nowadays is not worth it, so I recommend swapping the engine for a larger displacement one, which will give even better results.
