OK no joke. to the point 03 srt4 had no lsd and had a smaller injector. 04 They upd the injector and added lsd. the reason for the upgrade injector from factory is because everyone was buying the stage 1 kit and it came with new injectors and mopar grabs the aftermarket so they just included it. As for the mods running slicks (not sure what size) a srt4 with proper launch and no lsd stage 2 272 horse will run a 8.12. with lsd and stage one on street tires you can pull a 8.6-8.7 but it is greatly dependant on the driver as with any FWD manual car. Like i said you have to be very quick to run with them its said because they are so quick but its the truth.

As for the open front end on the SRT is to let in air on the air-air intercooler, the nostril ducts air behind the motor and past the turbo. its not ram air or anything just a fresh air intake.
