so, is it dumb to get these for a daily driver? I have a stroker, and I am ditchin the 18cc dished pistons for some mahle ones. prolly the -5cc dished. They have the power pack, and then the trick ones with gas porting. If you think about it, the reduced drag of 7 pistons at a time will free up some serious hp. So, anyone use them on a daily driver? Just curious how long they last, and if they are worth the additional money.
thanks

anyone?

 

wanna sell the -18cc ones?

 

sure do, pm sent.

 

I don't use them on street motors.

 

Why? How come they are not attractive for street use?

 

Common sence 'Stud-- They stop up and become less effective with mileage. They are subject to wear out the top ring before it's time,also.

 

no offence, but if it was common sense I wouldn't have asked. But, that makes sense, cuz the combustion gases slam the rind into the bore, so I would see how that would wear faster. Ok, thanks people. I guess I won't do it.

 

NO slam intended 'Stud.

 

The only way to do it is to use lateral ports. Yes, there are different types of "gas" ports.



I don't believe you can really take advantage of gas ports without using a 1.0mm top & 2nd ring. With that, you need a harder ring and a vacuum pump.
Instead, I prefer to use a 1.2mm ring pack and NO vacuum pump. Quite a bit less drag and if you get the right rings, they will last till your next rebuild no problem.

That "next rebuild" with a vacuum pump and thin rings,Just to run gas ports,gonna come sooner than ya think for a street car.

 

Ya, that's why we include disclaimers...

That last part is based on personal experience & edited for clarity.

Mine was too.
