it has a decent mods list.....

2003 Mercedes Benz SLK 230 Kompressor Renntech

Engine

6 speed manual
Spec Stage 3+ clutch kit
Renntech ECU Tunning
Renntech Crank Shaft Pulley
K&N Custom Intake
Renntech Cat-Back Exhaust
Supersprint Header w no Cats
Nitrous Supply 75 Wet Shot
With dual purge setup from under the wheels


aparently 380hp and running a high 12sec 1/4 mile..... dunno about 380hp (if so kudos!) but 350hp id consider more realistic....

well if u take away the nitrous shot he is making about 300hp.... so i think this target is achievable (keeping it supercharged). i think it maybe someone on the forums? would deff like to have a chat...

I am not familiar with the car but the 230 comes with what 198hp stock?

With his limited mods my guess would be he is more in the 300-310 range for hp.

There are several members on this board that have gone way beyond this guy engine mod wise, minus the nitrous.

A well tuned 32 will run in the high 12's if I recall, so that might be considered a guideline.... :)

The RENNTech exhaust is claimed to give 7 hp, but I had one and I strongly doubt it, maybe 2 hp at the most.

NOS is very safe. Every exception I have seen has been due to installation error or serious user error.
