LSA/ADM results

LSA kit with 2.75 sc pulley, #65, zl1 pump/adm fpcm, ls3 conversion, headers and 3" exhaust. Dyno results: 499 hp with 8lbs boost. I went with all the recommended upgrades except the heads. My goal was 550 hp! :(

My LSA blower got me 650 Rwhp on a auto. But we cranked it up to 14lbs.

I forgot to mention the BTR stag 1 cam! Curious, with all these upgrades, does it appear to be low? Thanks

My pulley combo was a 2.50 and a 8.66, which resulted in spinning the blower at just under 23k rpm. This in turn made 14 lbs on my set up. I've heard 1 lbs of boost is about 20 hp. You are 6 lbs less then I was, so (6x20 = 120). This would put you in the ball park if you cranked up your boost, so I would say it's your pulley choices.

I am no expert on the subject, but it seems a good starting point.

Tune good? Took decent timing? No leaks? Intercooler pump working and all air out of system? Correct and good plugs? Belt on properly so no slip?

If everything mechanically seems good, and tune seems good, time to pulley down.

What were your starting rwhp and torque? How many miles on the engine? Is yours and LS3 or L99?

LS3 conversion would indicate an auto.

Mustang dyno is part of it. If you want big numbers go throw it on a dyno jet. Could easily be 530-550rwhp on a dynojet.

~570 rwhp, 510 rwtq , 6 psi boost, stock pulleys. I have ported ls3 heads, dod delete, and a ss1 VVT cam.

Those were the final numbers after the VVT was tuned.

And yes Sunday is family time!
