Hello Everyone,

First off, I was unsure to which forum I should post this in. So I also posted in Evo Tuning and Results, just cause I thought it was a relevant question relating to boost.

So, I was just wondering if anyone could point me in towards finding or just telling me outright what the Stock/ Factory Boost Setting/ Number is for the 03-05 Evo 8's and also on the 06-up Evo 9's?? It would greatly appreciated. I feel like a dumbass asking but I thought it would make for an simple way to get answers, I tried googling it but all I could find were what people had post about the mods they have bought and how they affected boost levels. Any info is appreciated. Thanks!

i don;t think the link above works,. it tell sme that it cann;t be accessed for some reason.

 

yeah I tried the link too it said I Was insufficient to properly access that page. But thats what I thought it was around 19-20 psi. But I thought it was a little higher for the 9's?? Thanks for the input guys

 

Idk why that link didnt work... But this is what it calls out;

03-04s run 19.5psi at 3500rpm, which tapers to 16psi by 6500rpm
05-06s run 20.3psi at 3500rpm, which tapers to 17psi by 6500rpm

 

Ahhh Perfect thank you rawburt. Anyone disagree?
