It would be nice for Lexus to develop a true LS sports performance sedan because the F-sport offers very little. Currently I personally don't believe there is a market for a LS type AMG sport automobile. Just my 2 cents.

Note this is Wheel horsepower, not at the crank.

If it were my LS, I'd hold off on any intake or supercharger spend until they get around to tuning the LS. This sells for $650-$750.

There's nothing wrong with wanting an LS that can pulverize the rear tires or do a 0-60 time of 4.1 seconds.
There's a member here installed an electronic control on his exhaust for example. He's able to go from nice and quiet LS to angry LS with the push of a button; best of both worlds. The LS isn't going to lose any of its characteristics with more power per se, it'll just gain the ability to become a monster at a moments notice.

Anyway OP, as you can tell, the only way to make the LS faster (whether it be for 0-60+ sprints or top speed) is to throw massive amounts of money at it (case in point HKS's Supercharger). Unlike other cars, where you can walk into a shop and get a Stage 1 tune (typically just an ECU flash) for a few hundred bucks, we don't have an ECU tune to give more power and we don't have easy bolt on options to increase power output. I'm sure you can get a performance company to help you get the most power out of your LS if you're looking to do such a thing though and many LS owners would sure thank you for helping in the development of a tune and such. Good luck though!

Going so far as to even laminate the glass to reduce sound transmission. I would think if one wanted more power and sound you could build an IS or GS or even and RC and do it much cheaper. I just paid nearly $65k for my LS and a brand spanking new GS could've been had for much less. I know we all like to personalize our cars etc but the question is why start off with the LS platform in the first place?

I had a weekend turbo car that I sold after getting the LS. It slowly grew boring to me and I missed hearing some kind of noise. Added a JoeZ exhaust which helped. The car is quiet at cruise, but sounds mean when gassing it. I have been modifying cars for years. It is in my blood. With the 2007-2009 models dropping in price, we will see a younger generation buying these cars and possibly more aftermarket support if the demand is there.

Congrats on the supercharger brianlin! You are paving the way.

I thought about doing this.

I actually "get" wanting to add power, sound, exhaust note, etc

Yes the LS was designed to be serene, quiet, and subdued, but man's quest to mod their cars started LOOOONG ago. Everything from swapping out a Chevy Vega's engine for a 350 V8, or a Mazda Miata's 4 banger for a Ford 5.0 V8 (Monster Miata), etc. It's in many a man's DNA.

I do understand if you want more torque so you can accelerate faster, that's fine. I have no quarrel with BEASTIN wanting that. As long as you are going in a straight line and don't have to make any kind of maneuver at high speed you're OK.

It just never ceases to amaze me when I see these minivans on the highway doing speeds above 80 mph and some are swerving in and out of lanes. Their center of gravity is so high, not to mention inadequate brakes, tires, and probably driver ability. Those people have no idea what's going to happen when they have to brake or take evasive action.
