Thanks for your info, Peter.
I can see that the dyno is likely to be quite accurate, and that already that an excellent job has been done on your engine. Just look at that torque curve! I really haven't seen a road going 2 litre breath so well- outstanding job!!
As I understand it, you are running the Colombo cams, a sport manifold of unique design, a high flow air filter, and a remap, and already that unit is making 182BHP!
Best of all, now you want more!
I'm sure you will find a little more, but I still doubt that the target will be met. Still, I suppose it is something to aim for.
If the machinists can find that, please let us all know how they do it! I'll shelve my ideas of getting a V6, and just get a Twinspark! As it is, you car would give V6s something to think about. I was lucky to nudge 170BHP with my 75TS- and that was with 98 octane!
Exactly what is the cam timing with these cams?
One last point is the question of engine speed. You understand that torque is the turning force of the crankshaft. If the engine turned faster, but with the same force, it stands to reason that is producing more energy. Simply expressed, power=torque*speed.
That's why I suggested that to produce your target power output, your engine would need to turn much faster. I doubt that much more torque will be found, so therefore the power can only come through a higher engine speed.
Its not all bad news though. Remember that higher engine speeds allow higher 'in gear' road speeds which means that 2nd gear thrust will run out at about 10kph more. In other words, and neglecting the effects of aerodynamic drag, the car could have the same acceleration at 100kph as it did have previously at 90kph.
To put it another way, if our engines turned as fast as F1 engines, and ran to 20000rpm rather than 6000-7000rpm, we could enjoy the same acceleration at 160kph as we currently do at 50kph! (again, neglecting aerodynamics).
