z6/y7 pistons
 

hey i was wondering how long my pistons would hold up at 15lbs with an awesome tune on a 48/60 just for a lil while.. either my y7's or my z6's pistons with new rings. i was waiting to build my y8 block but im in college and have no income but really wanna get my y7 outta there its been running 10lbs on a t25 since june and it has 168,000 on it. so the plan was to block fill the y8 tt-rods and srps and then some head work running 20+ lbs on a 48/60. so right now im looking at just buying my rods and block filler stuff.. then some new rings and my z6 pistons just at 15 for the time being until i get money together then do the pistons. anyone think its a bad idea? im cheap but i want some more power

You're not going to run 15 lbs daily on a stock MAP that's for sure. Wouldn't even do it on a 3 bar. 10 lbs daily on that turbo will be fine if tuned correctly...

i'm runnin 16 daily on my stock map sensor. dunno why ??? not too concerned though

Re: z6/y7 pistons
 

Me too running 15 lbs on a z6 motor daily running a uberdata map and she been holding good

Re: z6/y7 pistons
 

on what turbos are you guys running 15 lbs daily on? I'm going to raise the BS flag on that one.

Re: z6/y7 pistons
 

Agreed. You need a different MAP sensor or your holding the same tune at 11.03psi on. Let's hear it fellas.

you can call bs all you want. i know that the stock map isn't sposed to hold more then 11psi, but i'm rollin 16 psi on a .48 .60 w/ stock map. like i said, i dk why

Stock engine?

the map wasnt really my consern but thanks anyways.. i think im just gonna go with srps after i start makin money again .. 25 lbs of no traction then

Re: z6/y7 pistons
 

well to answer your question, just wait till you do both. dont do just pistons, or just rods.
