I just came across a post by jbrady and realized it was his car listed on dragtimes.
Is it fair to say that jbrady is the CL member with the quickest ls400?
Are ls400 owners on CL just interested in looks?

Wouldn't exactly say that. Most of us realize that the LS is more cruiser than rocket ship. Since the 1UZ engine is VERY EXPENSIVE to do any kinds of internal mods to(which will show any sort of noticable difference), not to mention that there is VERY LITTLE in the way of aftermarket mods for this engine, most of us just dont bother with it. Yeah, you CAN do a 2JZ swap into the LS, but again, you are gonna spend quit abit of money to do so. Engine swap, custom wire harness, new custom driveshaft, tranny, new gearing for differential(have to gut yours out), intercooler, turbos, etc., can all be done. Just depends on how much you really value the car as well as how much you really want to spend on it. For all of that money you would spend to get the car considerably quicker, you could have just gone ahead and bought a faster car which is easier to mod and not quite as expensive to do so. Not saying that our motors CAN'T be modded, just that since there are limited resources to mod the internals in order to do so, the bill for "taking the plunge" can skyrocket really quickly.

I like that image - its what makes the ls400 such a great candidate as a sleeper (and it's lighter than a new camaro or ISF).

For me it's not about absolute speed - there's always something quicker and faster - it's about maximizing the cars performance potential. I think the lightest weight LS's, 95-97, have alot more potential than a 14.22.

I just checked dragtimes.com and the quickest sc400 was 12.68 @ 110.67. The lightest LS400 weighs about the same as an sc400 so we should be able to meet or beat that time.

plus the car you looked at on dragtimes was a supercharged, intercooled, water injected, and possibly somewhat lightened SC400.
we have a ways to go.

As note the 14.22 is my best times. That was on a 2.2 60ft which was due to traction limitations. Weather was near perfect with mid 40s temps and barometer above 30 inches.
My LS needs freshening up since it is at 150k miles on original spark plugs
On the above passes ( 3 separate 14.2 passes at 99mph) all it would have taken is a very reasonable 2.0 60 ft and I would have a 13 second time slip. Pretty respectable for a NA 4 liter 4000 pound car.
For me a stock engine with a performance tune such as the GS400/430 guys are starting to do plus a better exhaust (headers and cat back) should give my car a mid 13 second time potential at 100-105mph. That my friends will challenge more than a few "fast" cars. This is doable for a couple of grand.
BTW, I have the FREE LSD mod now so traction should be/is better.
I have been contemplating a low boost turbo design for some time but honestly have not rulled out a PROGRESSIVE port injected wet nitrous system of 100hp or less. With the above exhaust and tune with 100hp nitrous this should give a solid 400-420hp car (320-340rwhp) with 12 second potential.
I stress PROGRESSIVE as well as PORT and wet system. This would require drilling and fitting the intake with 8 separate foggers. A progressive system will give a starting shot of say 40hp and ramp up to the full 100hp as RPM climb. This will be safer and less stressful on the engine and transmission. It will also make the nitrous last longer. For a street application that rarely sees racing conditions this could well be the most practical approach. A properly designed twin turbo system will cost a minimum of $5k and probably run north of 10k before you know it.
