    Default 355 LE2 Dyno progress

    Finally got a decent dyno pull on my 355 LE2. Last time the transmission was acting up and didn't get a good pull. Rebuilt the trans and got 1 pull to 5200 Rpm. 359 rwhp and 454 rwtq. This was also on a mustang dyno. The tuner said that it's still making power but didn't want to push it farther cause it was building too much crankcase pressure. They're going to get a breather for the valve cover next week and see if that helps. Hopefully she'll pull to 6500.

    I don't think that torque number is right. I think it's too high.

    Locked in 3rd? Torque will be higher since the converter multiplies.

    5,252 RPM

    HP = (torque x RPM) / 5,252

    Auto trans pull will typically have a big spike when you nail the throttle, due to converter torque multiplication.

    I always love when @Injuneer cuts me off with his knowledge. I don't mean that in a sarcastic way or anything, it seriously makes me smile every time he posts and shares with us his years of knowledge

    Thanks!

    That's probably the best compliment I've ever received in the 18+ years I've been on sites like this. It is truly appreciated.

    In the end we all learn from each other, and I learn something new every day, much of it from this site.

    And thank you Larry.
