2.8 pulley nets how much boost?

[IMPORTSMOKER]

i have a steeda 2.8 pulley, stock lower, and only saw 13.2# boost max...i thought this was normal, but now iv heard that it should be around 15# any reason why im only seeing 13# or maybe is it that my pulley is not really a 2.8? only other mods are x-pipe w/ cats, 3" mac catback, straight shot intake?? thanks

my 2.93 made 14psi.. and 12psi w/ belt slipping... but i also have a ported eaton so it might play a role in the boost

on the dyno my 2.76 BF max boosted around 13, it may have been due to belt slip and the heat??(over 90 degrees when i dynoed) But if i were you I'd be more cautious of your RWHP rather than the lbs of boost youre making.

What kind of dyno did you use?, if it was a dynojet and made 417HP 463TQ with that pulley, i think you need to get a tune ASAP.

I have the same mods as you except a SCT xcal and i dyno 461/467. I got mines tuned at Racer Edge Tuning in Downey.

i am currently tuned with the diablosport predator "pulley tune", do you think this is the reason for my low hp numbers? the a/f is not very linear when i dynoed it...also, im getting a steg4 port right now, when i get it back on, im looking for a good tuner in so-cal that has diablosport tuning capabilities, any recomendations? thanks

Do you have an idler pulley? I guessing belt slip. You should be in the 450-470 range.

i do have the steeda single idler, and in the dyno graph it looks like boost hits a max of 13.4# around 5000rpm, then drops off to around 10# - 12# after 5krpm?? would that effect my tourque numbers (belt slipping) ? also it was about 84 deg outside...im just trying to figure out why my hp is so much lower than my tq numbers...it must be in the tune...

I have a 2.8 and I see 13-14#'s 4 pc set..on mine...

With a 2.76, I had 15lb of boost. Yours seems on the low side
