Put the LX on my brother's dyno over Christmas...you'd think the drivetrain was out of a Tiger II tank, only managed 277hp/330tq at the tire:






Doug Thorley headers and midpipes are collecting dust in the garage but can finally go in since I have a baseline number, more to come!

 

383hp and 403 lb-ft is claimed by Lexus.

Why the huge difference between claimed and actual?

 

Those are crank numbers for the 3UR; add in AWD and heavy-*** 21" rims = lots of lost power. 28% is on the high side for AWD losses, I was guessing it'd be around 22% as that's what my old GX had in AWD losses.
