Eric’s Dodge SRT 392 Dodge Charger Bolt On Package


Eric brought his dodge charger up to us for a few minor bolt on upgrades. Eric did’nt want to unlock the PCM yet, or have to get the vehicle tuned, but still wanted a few more pony’s. We made it happen for him with an 85mm A2Speed Billet Throttle Body, and a Legmaker True Cold air intake. We got a 40 WHP gain for under $1,000 without any tuning required!

Rick’s Dodge Challenger Shaker R/T Hellcat Short Block Conversion


Rick decided it was time for more power out of his supercharged shaker. The path he decided to go was to beef up his bottom end, add a fuel system, and turn the boost up. He made the jump to a Hellcat short block because it added more displacement while allowing him to run more boost. One more happy Hellcat short block swap customer, and another bad ass challenger on the streets!

This Whipple Supercharged Dodge Challenger is in for a custom A2Speed Chassis Dyno Tune. It came out very clean and OEM like. This build is prefect for any 5.7L HEMI owner that wants more power but doesn’t want to spend an arm and a leg to get there. With just this 2.9L Whipple supercharger this 5.7L is putting down over 500 RWHP. Best of all the power band is extremely linear and the supercharger is extremely well behaved.

Big Red; Luke’s Optima Ultimate Street Car!


If you ever doubted that a Challenger can handle it’s self on a road course, then you need to check out BIG RED. Luke of Steve White Motors has trusted A2Speed with his Optima Ultimate Street Car for everything ranging from bolt on’s, a full set of our Coil Over Suspension, and Custom Chassis Dyno Tuning. He brought his car up to us this time because he was having limp mode issues with a competitor’s cast VDO style 85mm true bore throttle body. It was replaced with one of our true 90mm Magneti Marelli throttle bodies and got a custom Chassis dyno tune. The results netted Luke an additional 36 HP over our competitors 85mm and that’s only half the story, at 3850RPM he gained a staggering 88 HP. When considering upgrading throttle bodies, do yourself a favor and do it right the first time. A2Speed offers real gains, no false size advertising, no magic mystery sauce, just results.

Greg's 5.7L to Hellcat Short Block Swap


Greg brought his already supercharged 5.7L Dodge Challenger R/T to us looking for more power. After reviewing the possibilities he decided to try something that hadn’t been done before, swapping a 5.7L short block with a 6.2L Forged Hellcat Short Block. He kept the phase 6 ported 5.7L Eagle heads, the custom blower cam, and rest of his prior installed accessories.
