ok this is a stupid questin and i dont have time to search. But what would a ballpark estimate of awhp be if i raised the psi to 25 instead of 19 stock.

2003 EVO SE
Everything is stock except 3in turbo back exhaust with no cat.

I was just curious...so please no flaming!!!



Thanks in advance

 

Youll probably hit fuel cut if you raise it to 25psi... I also dont think the turbo is gonna handle 25 psi for very long probably it will spike to 25 then fall down to like 15-16 psi...

 

Assuming you're using proper tuning, a boost controler, raising your octane level, and upgarding your fuel pump your are looking at 40 HP or more and at least 40 ft/lbs torque safely across the board, maybe more on an agressive tune.

 

you will definitely hit boost cut on the stock boost limit table. It will cut at around 23.5 psi or so. Plus, you'll likely be super rich without tuning the stock fuel map.

But, if you get a good tune and run 25 psi (you can only run 25 psi till about 4500 RPM) you can likely make around 300 hp/tq on a DynoJet.

 

Dont raise it to 25. You dont have the right supporting mods. 22 max

 

^ agreed

 

Ok thanks everyone i wanna raise the boost but am definately waiting to get supporting mods...Thanks again

 

22 will be plenty of fun, that increase in boost will do more than you are expecting.

 

it will not go the hight coz of the fuel

and you have to be tuned and you will need a walbro fuel pump and with race gas you can go to 25psi

 

What will be hp increase with my mods (sig) and no tune? i am at 21psi.
