On the honda turbos you have a much flatter and more useable torque curve that allows you to make the power much more linearly and further up the rev range.
Thats a PLUS point on the honda not a bad point.
2 engines
both 1 bar of boost
both 2 litres
1 makes 350lbft and 500bhp
1 makes 300lbft and 260bhp
which would you prefer?
cause thats typical figures for a YB and a F20C from what I have seen
This may seem stupid be stay with me....
I would have the second engine.
Simply because (for reasons i dont fully understand yet) from what i have see an engine with more torque than power always has a much nicer power curve for road use.
Im not calling the f20c turbo a bad engine, I fully auderstand that the way the delivery there power/torque is "better" than a zetec turbo/ yb but unfortunatly i dont like it.
I much prefer the power and torque delivery of a turbo engine that rev to an absolute maximum of 8000rpm.

Personally I'm not keen on the power delivery and it just seems you have to rag them hard to make progress. But that's purely a personal viewpoint probably compounded by the fact that I'm used to turbo cars.
Exacly briliant engines. but I dont like the way they deliver power.
