i found one for sale but hey has it running at 12psi... My motor is 9.9 almost 10 to 1 Will i get away with runing 12psi on pump gas or will i need a different pulley to make less boost

 

Thast still alot of compression to be running that much boost. I would pulley find another pulley combo and come down on the boost. What else have you done to the motor b/c if she has the stock bottom end then be prepared for a rebuild.

 

its a stroker motor with a big cam... i no u can run 11psi np

 

If you can run 11lbs without a problem then I do not see 12lbs being a problem. Also when you start messing with higher compression and boost you typically have to either turn down the timing or run race gas.

 

Forged components????

 

of course

 

OK I just noticed that you said that he says the D1SC set for 12lbs of boost. What kind of setup is he running? You will not see 12lbs unless your setups are identical.

 

i not shure i also found a S-trim .... Are they any good?

 

I have an S Trim i am going to be using because I already own it. I was gonna install on my my stock bottom, but decided to do a 383 buildup. It is a small blower for the cubes, but it will do for now.

Now if the person you were gonna by the D1 from was running 12psi on a 350, then you wont see that much on a 383. Also how well the heads flow can affect the boost levels as well. Big cc heads should show less boost then smaller cc heads (runners). Correct me if I am wrong.

 

my heads flow 275 at 600... he was runing it on a 355. but i no another guy that was runing a d1sc on a 383 a made 11 psi and his heads flow mid 250ish

 

Huh ?

Sounds like your heads flow alot better than his so you will make less boost.

 

Thats what I was thinking too.
