R1 Power Outputs
Who can tell me what bhp the different R1 engines are please. Are all the injection units the same 175 bhp ish?

98 - 02 engines all make about 150 BHP or so and rev to 11750 RPM. 04 - 06 engines make175 ish because they rev to 13750 RPM.
02/03 FI engines are said to make 1 or 2 BHP more than the carbed ones and 00/01 engines are supposed to be slightly better than 98/99. I think there
isn't much in it.

hi having owned one and been in both
the injection engine which is up to 20-30bhp more than a 99 carb engine does not deliver its power so aggresively I dont like this
IN theory only on track due to its better top end power would you unleash the very late r1 engines ie 2004 and later
I prefer the carbs power delivery 150hp
fuel injection 2001-2003 160hp
then about 170bhp
and now 180hp

Thanks chaps, interesting what you say about power delivery. I was thinking it would be the other way round ie. the FI engine would be smoother and
more useable. The potential extra power of a 2004 + engine should surely make for a faster car. Has the gearing been altered at all?

the 2002 FI engine is supposed to be smoother than the carbed engines. The 2004 FI engine is quite a different beast. It is tuned to produce power
and torque further up the rev range - it revs to 14000 rather than 12000. 1st gear is taller than on earlier engines too. The lower torque at the
bottom end and the taller gear makes the car slower off the line although the taller gear and higher revs mean you can hold on to 1st gear quite a bit
longer - 65 MPH with a 3.62 and 195/50/15 versus 52 MPH with a 98 engine. At the same time, all the other gears are shorter, making the car more
revvy at speed. 70 MPH is 7400 on with a 2004 engine or 6800 with a 98.

hi mate thats what I meant sorry
there all driveable but I prefer the RAW power delivery my 99 r1 carb engine had
I dont prefer the smooth power deliver FI gives you
youd have to have a 2005 or 2006 engine to even get the 20 brake difference
Im now using the ZX9r engine at half the price and with the car weighing 60kg lighter there should be no major difference between my ST and MK r1
