+1That is a huge misconception.......that Turbos are cost less alternitive to building the engine. It's just not true. In order to have a turbo motor that is going to make any significant horsepower gain over stock and be expected to last any amount of time you would have to build the motor to take the added strain of the turbo.....plus the cost of the turbo.......You will spend more money in the end.The cost factor plays a big role too. I'd rather just turbo it than the bore/stroke idea which costs ..what 1.5-2X the amount.I would consider doing the opposite....boring with no stroke, if you only wanted to go in on direction.Chip,
I have an 01 1000 (stock internals) and was thinking of just stroking the crank 4mm and not doing any boring.
What kind of hp/torque gains could be had and is it worth it?
Would I need aftermarket rods?
If you are going to stroke it, you have to spend the same money as if you were to bore and stroke it. Pistons have to be replaced and depending on the stroke, so does block machining. There are several disadvantages to stroking that have to be compinsated for, like side loading, frictional loss, and Piston speed. If you stroke it would deffinately have to use aftermarket rods and pistons......why not use bigger pistons?
I would suggest and 1143cc combo.....3mm bore, 4mm stroke....and around 205hp and 110ft-lbs of Torque........MotoGp power for the street...
You need a solid foundation to build a reliable turbo bike.
Chip,you going to the Pro-Star season opener in Georgia this March??
