  • lol! dyno numbers

    Okay, don't laugh too hard.
    This is a 3.1L with 160,000 miles, dirty air filter, ASP pulleys, hypertech streetrunner chip, no cat, flowmaster 80 series.

    121.4hp/152.3tq

    Since its an old engine I only had them rev to 5000. This is really sad, but with a 20% drivetrain loss, I estimate 152~hp and 190~tq at the crank. So basically my mods have put me at 12hp and 10tq more than a stock new engine.
    Tomorrow I'm going to try 91Firebird's custom intake setup and Thursday night I'm heading to the track for a few passes. I'll let ya know how it goes....

        it's good to have some "real" numbers [img]graemlins/thumbsup.gif[/img]

        how much did it cost? the only place around here wants $125 for 3 runs. that's way too much for just 3 [img]graemlins/bs.gif[/img]

          $50 for 1 run.
          However, I hear there is a tech school around here that teaches people how to operate a dyno. Since its done by students, its only $10 a run. I may have to check into that.

            Actually I think that is really cool
            I like the tq number.
            You are bummed out about your gains, I only saw 178 rwhp w/ all my mods?!?!?!?! (na of course)
            I wonder if a wide band was done maybe there might be another 1 or 2 hp lurking around, who knows??
