Default Lysholm 2011 4.8 dyno today

Decide to baseline my truck before I did my LPP headers. My previous dyno was done in Hawaii so I wanted the numbers to come from the same dyno and conditions.

Hawaii dyno 400 whp 404 ft lb tq

Georgia dyno 391 whp 454 ft lb tq

Temp was 70 degrees and had a mix of 89 and 93 in the tank. No new mods since Hawaii dyno. Both dynos were on Mustang Dyno's

Enjoy

One dyno is with the converter locked for tuning the other is unlocked would be my guess.

What psi was the charger running during the dynos?

Both were at 9 psi. I believe you are correct about the torque convertor. THe first dyno in Hawaii was during the initial tuning session. THe dyno today was straight off the street onto the dyno,unplug the rear wheel speed sensors, stick it in 3rd and run it.

It will be nice when I get the truck to Henson in Birmingham to get it fully tuned including transmission. That will be after cam, springs, and stall convertor.

Thinking the same thing.

Strong numbers. Can't wait to see what the headers do to your numbers.
