n when i do upgrade to 3" exhaust wats the max psi i should run on that? ......

Spell check is your friend.

Many things depend on your tuner, dyno etc... Your probably looking at high 300's.

 

The individual building my block tuned a car on stock motor with that manifold and a 3076 on ??psi, it made 531 on the dyno. The potential is there as long as you have the supporting mods and tuner. And please do touch up that OP

 

my eyes hurt! Spell checker and rudimentary sentence structure are your friends.

 

This forum is for information about s2000s that is needed by their owners. It is not an english class where people should have to worry about spelling. So answer the questions ppl!

 

Noone said it was, but if you want someone to even reply to something you are asking, you should at least type it like you are older than 11.

 

lol sorry about my typing.... im used to texting with my phone lol..... anyways im just interested in the estimated whp range that the car is capable of making with the restricted exhaust............ the 2.5" to 2.36" (60mm)

also what is the max psi can it handle with this kinda setup?.........

 

thoses questions are dependant on a lot of variables.(type of fuel, tuner,Tuning software) with a good tune 18 psi-22psi should be ok with the 3mm installed. It would help to have a higher flowing exhaust but it should be fine untill you can get larger piping. I would expect some where in the region of (depending on the dyno used) 370-420 at around 18 psi
