Possible horsepower from a 98 LS400 ?
Jus wondering how much HP a 98 LS400 puts down to the wheels in stock trim ???
And how many NA wheel HP is possible with headers, full mandrel bent dual exhuast, CAI, tuned ECU, and anything else that can be bolted to this engine (like ?) ???

"engine is rated at 260hp and I expect the tranny and IRS to eat up apx 50hp leaving apx 210rwhp. "
jbrady is the man when it comes to performance mods on the '98-'00 LS's...you should try PMing him or try a search for his threads.
Here's a few to start you off:

I think he was reffering to 95-97, as the 98-00 are rated at 290Hp.

It just completely slipped my mind that jbrady was talking about his previous 2nd gen LS (before he got the '98-'00 model) which indeed does have 260hp and not 290hp....sorry about the mistake and thanks for the correction.

The times in my sig were with mediocre 2.20 60ft times. With sticky tires I could probably get close to a 2.0 60ft. A 2.0 on the below pass would have been a 13 second pass with nothing more than a little weight removal (1/4 tank gas, no spare/jack, no extra junk in car, no rear mufflers) and perfect air (44 degrees, 30.4 barometer).
With performance mods and sticky tires a mid 13 is very realistic...
Driven properly of course
