What's the most bhp you can get from a 998cc?

Don't forget you could always short stroke a 1275 motor

Why do poeple look at the BHP... when its the touque we feel?

HP = Torque * RPM / 5252
therefore... more power = more torque !
Which is why all power curves from dynos which have both power and torque curves plotted cross at 5252 rpm :smartass:

What would you say if I put that into my 1293 stage 3 engine? would that up the power?

am i right in thinking a short stroke motor revs higher and can then produce more power if you can get enough fuel and air into it and out of course...
like bike engines tent to be more large bore short stroke they make more power but less torque than a car engine of similar capacity

thats what happens when you make posts late at night
I might leave the short stroke idea... I am happy with a 1293, with a X-drilled, and nitrocarbonised 'n' wedged crank!
Might be an idea to do with the old 998 lump... wonder what a few little twaks can do?

Of course more is possible if you are willing to sacrifice reliability.
I have seen a supercharged 850 in MiniWorld with 85bhp

There is no reason that you couln't achieve 100bhp and still maintain good reliability if you used modern car systems and technology such as fuel injection. You could get this without all that tomfoolary but not as easily, and if you did both you could get much much more. ie turbo's, 8ports, 16v's
Late Rover 1.8 K-series unit: 180bhp
Honda 2.0 VTEC: 200bhp
Both these run on the 1st principle of an easy 100bhp per litre
Mitsubushi FQ400 2.0: 400bhp
Thats just plain ridiculous, but pretty amazing when it matches a Ferrari 360 for example 3.6 V8: 400bhp
Of coursethe Mitsubushi is more highly strung (and if i remember has 4000 miles service intervals)
So it really depends on how much energy you want to put in to it as well as money.
All of this maybe missing the point :tongue: i just think its amazing some of the comparisions being made.
If you took the FQ400 principle to the 998 you would be getting 200bhp and your 1275 would get 266bhp!

Nah I think I am happy with my 80-100BHP, least it will be reliable
