Lexus LS400 Custom Exhaust
This is my 1990 Lexus LS400. It has a custom 2.25" Exhaust with magnaflow mufflers. I got rid of 2
of the 4 cats. You can see my build at cardomain.com.
Supercharged Lexus LS400 on the dyno
Stock 263,000 mile motor, stock Exhaust, everything stock except for the
addition of the blower.
3psi Boost. No Intercooler. Project cost $1350 total.
Dyno result is
245rwhp, 245lb-ft torque. Air fuel ratios well below 10:1 above 3000RPM.
The car now has about 280,000 miles on it; the Supercharger was removed and sold. It was a fun
time while it lasted and I think that forced induction is mandatory on the
1UZ-FE-equipped luxury liners Lexus built.
