First of all, excellent job! Until someone does something like this they have NO IDEA how much time, work and money in involved.
Now, regarding your power. The only thing that matters is power to the road. You have 230rwkW = 308rwHP.
Now, actual drivetrain loss is a function of the entire system AND weight. I would suggest that with a lighter vehicle your loss would be somewhat less than a stock Lexus.
That said the original engine was rated at 250hp and typically makes 175rwHP. If true that would be a 30% loss. I argue that the original rating was wrong and have given many examples. I believe the 250hp was marketing. In 1995 the LS400 was revised, the engine improved and rated 260hp. Performance improved by a FULL SECOND 0-60 and 1/4 mile. Not a realistic gain for 10hp... more like 30+hp.
So, lets look at the newer and more dyno'd GS400 rated 300hp (accurately IMO). These typically make 235rwhp. Math says 22% loss = 300hp. I think a 22% loss is a realistic and usable number.

V883,
Your pm should work right? Do you have any problems with PM? Your pm should work like everyone else... Please let me know if there is any problem with your pm.
Update: Bill, you accidentally turn off the PM. I manually turn it on for you. So it was your profile setting not from our side.

What an awesome setup you got there!!!! Let me get this straight...you have around 300 RWHP and 650 lbs of torque???? That is quite an achievement and a well deserved # for everything she has put you through.
Congratulations once again!!! Enjoy that beast

You serious?! I don't like it at all but someone yesterday said they liked it as well. I may start changing my mind. The engineer made me put it on as a condition. He said he didn't like the "pinch point" at the blower pulley. I didn't want to argue with him so I got the lads to build me shroud of their own design. This is what they came up with. It runs all the way down the right hand side of the belt to the Air Con pulley.

Interesting! You put the extra injector precharger. Any problem with that?

Very nice work. Though in my opinion it would have been cheaper and easier to achieve these power levels with a turbocharged 7M motor installation, the quality of the work done on your car is nothing short of remarkable and if the torque figures are right, the power is definitely there too.
I agree let alone for the money what I could have done to this motor but the real buzz was to have a supercharged V8. You turbo guys are way off in the 1000s now and though that sounds fun but I like the sound and immediate grunt of a V8. Not much horsepower (I tell anyone who asks that it's got about 380hp) but the torque is cool. Still, I'm starting to get used to it. I think I need about 100-150 more horsepower (got plenty of torque) before I'm satisfied with this engine. The problem I have is that they lowered the compression too much (8.3:1) for this blower (11.5psi - max). This engine can easily handle twice that much boost. I might bolt on a Whipple or at least a 112. Also, the exhaust farts until I really get on it and it's bothering me. It doesn't suit the car so today I'm going out to fit my 6th cat-back exhaust system...sigh. I just MUST have the right sound and though this engine can't be beat for sound when it's singing the 6,500 Grand Opus it sounds like a 253 Panel Van with too large extractors and no balance pipe when I'm squirting past people.
The oil filter sits behind the front bumper along with the water injection pump (which is too loud and on all the time).
Here are some exhaust pics for you but like I said, that's about to change.
