Turbo?
What experience?
- Road cars? (almost exclusively Compressors for Petrol Engines)
- Race cars? Which series uses Turbos?
Seriously: The limiting factor will be the available amount of fuel.
Only Efficiency will buy you usable HP. And in that regard the difference between the manufaturers will be minuscule.
People have been designing IC engines since more than 100years. Technology can be considered absolutely matured.
The road car manufacturers spend many hundreds of millions to gain high single digit % efficiencies from one engine generation to the next (5-8years).
Does anyone really expect one manufacturer to find 20% compared to the others immediately and with a tiny fraction of that Budget ???!
