Hit up the dyno again yesterday 298hp, 254tq, same mods as my previous 12th best for the LSJ motor
Only change in hardware was an LS4 throttle body, not sure if theres a coding for that
anyways heres the sheet

seems low for a TVS, what size pulley are you running? Supporting Mods?

That graph is kinda weird at the top end it look like it looses a little power then starts pulling upward again. Maybe that is where he let off at the end of the run. How come you aren't pulling to almost 8K like Area47? These supercharged cars make way less peak torque than us turbo guys but the torque does not drop off much at the higher rpms so it enables very good peak HP.

he doesn't have the valve springs, or the nuts to do it
lol!

Get some valve springs and push it over 300 WHP easily. Bet that super screams at 8k RPMs

:lol: :lol: :lol:. Still on stock valvesprings that explains it then. Bet it makes peak power at about 7400 rpms or so.

I have a completely stock motor, no internals, no cams, therefore the rev limiter is at 7200. The main issue was spark blowout this was killing the torque once the boost got above 19 or so, so once thats ok, better numbers should occur. I have no idea how or where to get valvesprings done so I can't do that.

what pulley are you on stock or 75mm? and how the hell all you guys keep getting spark blowout

80mm pulley, and I'm running stock heat range plugs gapped at .040, thats why theres blowout at 21.5psi
