i think the dealer would have to open the engine to tell that the internals have been messed with.

 

My winter truck has a 4.3l v6, so it's possible.

 

So how much will it cost ot make it at least a 3.7 and how much hp is expected?

 

i saw a supra stroker kit here http://store.yahoo.com/sgpracing-store/enel9.html


9k!!!! that is fooking rediculous!!!... i would do alot of other stuff before that.. it appears to be only pistons and crankshaft

 

so how much hp gains is it? It dosent say. How much will it cost to balance the pistons on a VQ engine and how much hp gains is expected?

 

Sorry for the dumb question, but what is a stroker kit? And what does it mean to have a stroked engine? No smart a$$ comments please

 

Basically when you "stroke" the engine you're just upping the liter displacement and you do that by buying a stroker kit.

 

Boring and stroking are two ways to increase the displacement of the engine.

Stroking- a short form of saying "increasing the stroke of the engine." This is usually accomplished, i believe, by buying a crankshaft (and connecting rods?) with a different radius between its centerline and connecting rod mounts. This has the effect of increasing the difference between the piston's top dead center and bottom dead center positions, thereby increasing the amount of air/fuel the cylinder can contain aka increasing the displacement.

Boring- refers to increasing the diameter of the cylinders and replacing the pistons with larger (diameter wise) ones in order to sit in the larger cylinders properly. This increases the volume (pi times cylinder radius squared times stroke) that the cylinder can hold at bottom dead center versus top dead center.


Im not quite sure about full scale gasoline engines, but ideally, 1/10th scale nitromethane/methanol engines are "square," meaning the bore equals the stroke of the engine. Longer strokes give you more torque, but shorter strokes give you higher RPM capabilities.

 

sorry to bring back an old topic but how much will engine polishing and balancing give hp and tq wise?
