Our good friend DRP (aka Dan) went through several sets of mods last year on his SRT8 Charger, and to meet his goals we ended up putting together a great engine package for him, as follows: - Arrington 426 Short Block w/ 11:1 compression - Stage 3 Ported Heads, refreshed by Arrington - Arrington .645/.645 Cam w/ 114 LSA - Ported Intake (previously installed) - SLP 25% Underdrive Pulley - Arrington 90mm Throttle Body w/ Nitrous Ports - Arrington Carbon Fiber CAI - MSD Coil Packs - Pro Torque 2800 Stall Converter - ZEX Nitrous Kit (we had previously installed) - Kooks Long Tube Headers w/ Catted Mid (we had previously installed) - Cragar Catback Exhaust (we had previously installed) The car was recently re-tuned by Johan at Diablosport and put down an impressive 525 RWHP and 511 RWTQ naturally aspirated. We just installed Paramount axles, a Quaife and Paramount valve body last week, and will be getting some nitrous numbers and 1/4 times with the complete set-up soon! Here is the n/a dyno sheet ...

It has been great to work with DRP and all the vendors, as we were able to spec out the build, get approval from the customer and just do our thing. In the end, we are all super happy with the results! We can't wait to see the nitrous numbers, so stay tuned!
