I Compare the 5.3L V8 and the 2.7L TurboMax I4 Engine in the Chevy/GMC 1500 engines to see which engine performs better, which engine is more fuel efficient, more powerful and which engine tows my 8,000lbs trailer better. I also discuss reliability, longevity and overall the differences between the old school V8 engine and the new school Turbo charged engines.

This was a video I was very excited about making. I was very curious to see how well the 5.3L Ecotech 3 V8 in the chevy 1500 pick up trucks performed when towing my enclosed trailer. last week we towed with the 2.7L turbomax engine and I felt like that engine was just underpowered.

I felt that the turbomax with only 2.7L of displacement was at its limit and revving very high and working very hard. this would result in premature wear and probably effect longevity of the engine if someone was to tow this much weight constantly.

So I thought it would be fun to compare that smaller turbo inline 4 engine to GM's flagship V8 the 5.3L and well as you guys saw there is no replacement for displacement.

the 5.3L V8 was better in almost every performance metric, including acceleration, RPM control, pulling hills, fuel economy and transmission temperature control.

I think the biggest surprise for me was just how much more fuel efficient the 5.3L V8 engine was over the 2.7L turbomax. It used almost 25% less fuel running the same distance with the same trailer. something you don't expect.

I think the 2.7L turbomax engine is great but there is still great value in a N/A larger displacement V8 engine that gives better throttle response and can put in larger duty cycles.
