sitting at work and got a idea


Recommended Posts

ok lets see what the brains think of this. me a a few friends i work with all have banshees. one had ask me about the vitos super stock pistons the ones with the grove on the exhaust port side he said he may get some for his stock banshee he dont want to port it his cylinders are about at max and is trying to save for a serval but wants to make it another season on what he has but wants some more go power. then i got the idea.

ok i got a 421 serval still putting it together and dont plan on trying this yet anyway lol but what would the affects of them be on the power band of the serval if you ran the 68mm blaster super stock pistons. would it keep the bottom end of the serval, or make it into basicaly a cub power band or just be a total piece of shit lol kinda gets boaring at work so lets hear some ideas.

It might not totally kill the bottom end but it would definitely carry less ottom end. You could make up for it with compression since you need to have domes cut for the blaster pistons anyway. In my opinion though, don't bother. Run the serval the way it was intended. If you wanna get more out of it port it. I guess you could run the Vito's slugs like a test to see how it would feel with a bit of work, but that the CP cylinder has a totally different port layout then what the Vito's pistons are made for. So it probably wouldn't run right.

hey i have stock motor and toomey t6 pipes- what would happen if i put the superstock pistons in my motor being as t6s are made specifically for un ported motors?

worth doing when i rebuild top end or wiseco??

ps wanna keep the t6s

 

have seen threads on this but no serious answers

i have no idea what it would do ive never ran them in anything but my buddy is goin to get them for his stock motor with t5's ill let you know on that. i didnt plan on running them in my serval but it was kinda one of those huh wonder what would happen if you did this with this and wam total fail or win lol.

The vito's pistons represent a simulation of a raised exhaust port. A serval has an exhaust port timing that is lower than a cub. But putting those vito's pistons in would give you a massive high exhaust port timing.

Your head was working on an interesting idea though.

It would probably be a good idea, if it wasn't a bad idea. The reciprocating mass simply will not generate enough inertia to fully energize the rotating assembly. Therefore due to the poor thermal transfer associated with the lack of flame propagation, the efficiency of the combustion dispersion will be insufficient. The only possible solution to this would be to artificially adjust the stoichiometric mixture disproportionally. The drawback to this however would be that it may slightly distort the non-constant ratio if specific heats and combustion products dissociation but is typically very similar. Hence the two profiles may not be similar in appearance. Thus: Pm = W net / V s = Net work done per cycle / swept volume. So in other words the mean effective pressure is the theoretical constant pressure which if it acted on the piston during power stroke, would produce the same net work as actually developed in one cycle.

 

In other words, that shit won't work.

when the fuck did you turn into a 2 stroke expert?
