It got me a bit hyped up so I was looking for what the possibilities are for our SRT (in my case a 05 Roadster with 55k km).

Some shops here have a Stage 2 chiptune giving 380HP with 485Nm (https://www.procartuning.nl/chiptuni...-6-335-pk.html ). Thats only the ECU. If I would also add or only mod the intake with a DCAI from needswings, thats also quite a boost.

Anyone more info? The info is quite scatered on this website. Dragtimes have some records of stock cars doing 12 or 11 second drags, which is quite fast. Jim seems to have made 10s with a different engine afaik.

First of all.

you cannot expect 380 hp just with a tune. crank hp not wheel

most of the srt6, slk+c32 amg`s are between 330 - 350 stock bone. again crank not wheel

you can expect a realistic 15 hp with just a tune. I think more than 15 but 15 is a good number

i would go with tune, 65mm pulley and K&N fillters. you do not need the Needswings or SL55 dcai. With the listed mods +35 -40 hp and much more torque than stock. don`t trust the tuner numbers.. do a initial dyno and a dyno after mods.

i would go with tune, 65mm pulley supercharger pulley , if u do a pulley crank or supercharger ,,,GET A AFR GUAGE
yes you do need an intake ,,Needswings) 10 to 20 hp depending on the other mods or a e55 intake 5 to 15 hp (an engine is a air pump you have to get air in and out to make power others have done the dyno test for you just get a AFR (air fuel ratio) don't go over 12.9 (to lower it add fuel ) some pulleys makes your air fuel ratio too high example a 65mm supercharge pulley with no other mod your AFR will be close to 13 if not over. jim
