A 2.5 or 2.3 l is a car engine... just saying!
for the sake of debate, 1.6l at 26 psi is a 2.7L
Just saying that the highest power rocket right now is the TTS performance built supercharged 2023. Its 342HP at the wheels and is running 1 bar (14.5psi) If you some how made this apples to apples the toyota 1.6l wins HANDS DOWN for power to displacement ratio by a mile! And this engine is not new tech but certainly produced within the same few years! Its just cool that its a 3 cylinder thats thumping skuls and taking names compared to anyting close to its wight and power output.
1.6L @ 26psi = 2.9L @ 14.5psi i.e. NA?
As in (1.6 / 14.5psi) x 26psi = 2.9L
Curious as to where the 2.7L comes from.
But anyway isn't 26psi the
boost the Toyota runs, so it is really 40.5psi absolute?
So then the 1.6L @ 26psi boost will process the same volume of air per cycle as a 4.5L NA engine?
Whereas the TTS Rocket, if using 14.5psi boost, is only 29psi absolute. If it also ran 26psi boost, it would produce 559hp or 224hp/L.
It doesn't matter what size engine it is, if it was made for a motorbike, then it is a motorbike engine (typically the one block contains the engine and transmission).
A car engine is one that was made for a car (typically trans is separate unit but mated to engine).
I think you mean 2.3 or 2.5 is a car "sized" engine, maybe?
I believe TTS' Rocket at 342hp is wheel hp, so engine will be about 400hp assuming similar transmission loss as the older Rocket III.
That's about 160hp/L. And 275 ft lb at wheel so maybe 324 ft lb at the engine.
GR Corolla at 300 engine hp and 1.6L displacement is about 188hp/L. It makes 273 ft lb at engine.
Impressive indeed, although it has traded a lot of torque to gain that hp, but note well that the Toyota engine was designed to be a forced induction engine. The Triumph Rocket was not.
I would wager Toyota reliability might win hands down though vs the modified Triumph.
Anyway.... the Mitsubishi Evo 8 FQ-400 beats the sh1t out of Toyota, 20 years ago it was producing 202hp/L.
