Real boost with 5lb pulley on Roe Surpercharger

[Schulmann]

Just by curiosity I am wondering what is the real boost with a 5lb pulley on a Roe Supercharger. Unfortunatly I don't have a boost gauge installed. I used the VEC2 logging software to measure the boost with a 5lb pulley. It gave the following average values:

4.3psi at 2000rpm
7.0psi at 5500rpm
Temp: 40F
Elevation: sharp at see level

What is you real boost ? (and configuration)


I am also interested in injector pulse offset on cylinder #10.

 

[99 R/T 10]

If you're like me, (even with taking a little fuel out at idle), you're running rich on #10. I put in the standard champion plug in that hole to compensate. I have a little boost creep at higher RPMs, but for the most part 8lbs.

With the VEC2, can't you "correct" the fuel flow on each individual cylinder? I think you can... Actually, I know you can. using a different plug is another way...

Yes I was thinking about running a hotter plug just on cylinder #10. Is this a good idea ?

But I still interested in real boost values.
