I don't get how the newer hot hatches closer to 300 horses manage to transfer the power.
That'll be the computer ;)

Well on the supercharger/forged engine setupni had before i was pushing 350bhp and 260lbft of torque.

Put the power down just fine. 245/40/17 tyres though.

I havnt got my high output n/a Prelude back yet. Atill being rebuilt so i cant say.
F/i to n/a isnt a fair comparison.
I was roots supercharged which makes the engine behave like a much bigger naturally aspirated engine. Honeatly being supercharged felt like a big block v6, instant throttle and torque response but power and torque rising in a nice linear fashion.
So much torque in any gear instantly.

Downsides was huge belt slip, epic heat, epic bad fuel economy and parastatic drain on the engine from the charger being belt driven. The jrsc setup doesnt present many new noises like pulley and belt noise and tlthe charger takes away that 90s honda vtec charactetistic.

Im expecting high output n/a to have no real disadvantages but bring more than stock power and that legendary vtec engine character.
Better fuel economy and more reliability day to day.

I can wheel spin the s660 with all 64bhp but it have to be very very wet.
