Psi out of a 38r on stock fuel ?

[faster6.0]

Just curious to what kind of boost psi you guys are seeing on these with stock sticks, just did a 38r on a customers truck and it pulls nice and build boost but haven't seen it over 28-30, I know my s366 Jb would peg a 37 psi gauge and keep on pulling but with big injectors.

I got about 33-34 with 160/100 on 1,15 housing... that sounds right.

I see 35psi with a 1.15..

Your fine... In reality you should see lower boost numbers with the 38R then the stock turbo. Larger exhaust housing and such...

Would not expect to see more then that.

With just my chip and on my hot tune I see 26-28. That is also with a weak a$$ HPOP but I am guessing that 28 would be about max with just a chip on stock sticks.

I saw 30 on 160's and brand new up-pipe donuts so...

Yes...

My insight and analog gauge are saying 35-37 with 175/80's. Im running a 1.00ar wg housing.

with my stage IIs I had it would do 33-34 PSI but on the stock worn out sticks with a worn HPOP I do 26-28

I make 29-30 with tunes and stock sticks

With the 250/200s the maximum boost I see is 34 so yeah that seems about right I saw 30-32 psi with the stage ones
