I heard some say a stock evo pushes 19psi and others say 21psi. How much does it really push stock?


Thanks

 

20

 

Why not do a search?

 

Too lazy! Plus im at work. My boss is walking around. HEHE

 

Because it is a lot easier to ask. LOL!
My car pushed 19 psi but it depends on the gauge and how it reads.

 

20

 

More then tony montana..........

 

it depends on the weather...
cold nights i can hit 19
hot days it wont even touch 16

with a mbc you dont need to worry about the weather to much though, because it doesnt really affect it

 

Stock, my car used to peak boost 20-21 @ WOT, then taper to 19-18 then drop to 15-13psi after 5500-6kpms.

After MBC and tune, it does 22psi and holds it there all the way @ WOT.

Ofcourse, cold days, better gas and what type BOV will change it dramatically.
For example, on Cold days I boost 1-2psi more.
w/ 100oct I boost 1-2 psi more.
The stock plastic DV was peak boosting around 22psi and then drop to 21psi @ WOT. I changed to MR DV and my boost gauge read 25psi and then drop to 21psi. Basically, my MBC was set @ 25psi and my stock plastic DV was leaking bad. After changing to MR DV I had to re-adjust my DV to 22psi, and it stays there all the way.


Hope that helps.

 

and the 8, I have one, and i have a manual boost controller i have take it to 19psi, but is no accurate, sometimes it passes to 20 or 21, but I dont know if I am in the limit
