hey im not sure how much boost i can get out of these turbos without compromising durability or efficacy. they are the 99's i know they made more than one set these are the ones that produced 285hp anyway anyone know where do get this graph. ive seen one for the older 93's but i cant find that one either. please heeelllppppp.

15 psi max..... for efficiency reasons

 

post the one that you have for 93 spec turbos

 

you really think 15psi would be safe? that would scare me. would it be better to run non-seq at 15psi?

 

it should be better to run non sequential at high boost........ cuz on sequential, the first turbo spools up to max boost then spools the second one ..... on a non seq, the spool at the same time



at least thats my understanding of things........ someone please correct me if im wrong

 

yea it makes sense to go non sequential. but no one has these graphs.



i dont have the one for the 93's although i have seen it b4 on some web site or another.

 

eh i like non seq... more predictable boost... and if you see my engine bay, you'd understand 3 vacuum lines.

 

probably easier to controll boost too right?

 

yep...

 

so do you ever run at 15psi? if so what kind of power do you get out of the extra 5psi? i'm just curious cuz i'm gonna switch my j-spec turbos to non-seq soon.
