Stock boost?
Hey guys,
I have a 91.5 with an auto. I just installed my boost gauge this evening and took it for a test drive. I'm seeing: Almost no boost until I get into second gear. Second gear tops out ~14-15 psi Third gear gets up to almost 20 psi....but I have to be floored for that. I turned my pump up about 1/2 turn (left the collar on), did 90 degrees on the star wheel and turned the pin 90 degrees. Does that sound normal? For some reason I was expecting ~25...I don't know why that is though...just kind of what I thought. Any feedback on stock boost levels? I'm not sure on the housing, but since it's early intercooled I want to say it's the large housing (dog). Anyway, thanks! damon |
stock boost should be between 18 and 23 psi of boost somebody will chime in if i am incorrect:humm:
|
Thats correct
|
Sooo....everything on my 'semi-baseline' looks like expected for a stock truck with 155k on the clock and a 3 inch exhaust?
|
The no boost in 1st is kinda odd... Make sure you dont have any kinks at all in teh boost line, even a spot that was kinked and then bent back is a problem.
|
Roger that...will do. That plastic line is terrible to work with...especially when it's below freezing out. ;)

With the 21cm housing, and the mods you have done, your boost numbers seem fine. |
Alright, thanks!
Actually, after driving to work this AM I will see 5 or so psi in 1st. Just not very much...of course, it isn't in 1st very long, either. |
you got it your fine keep :rocking:

For a factory intercooled truck, that is higher than normal. Even a Non I/C truck stock shouldn't see that much boost.

you use first????????
my first gear won't even make it to 10mph.. I always start in second :rocking: |
Automatic...not really any choice in the matter. ;)
