• Horsepower Freaks RHD (right hand drive) E46 M3 S54 twin turbo kit nearing completion

      That's right, we said twin turbo kit, not single turbo like all the other HPF S54 kits. Why two turbos? Well, due to the right hand drive steering column making turbo placement a pain in the butt. The video below that HPF released explains the clearance issues quite well. What we are particularly interested in is how the twin turbo kit spools compared to the singles and if twins will become an option for left hand drive cars as well. Dynos to come in the next few weeks along with pricing details.

        Was a rear mount setup considered? It has proven itself a great option to traditional setups w/ much lower IAT's. From what I've read (I'm no expert), the slower spoolup due to cooler exhaust gases can be offset by A/R selection.

        Not sure if a rear mount was considered but rear mounts are kind of looked down upon.

        Yeah, I was skeptical at first too, but anyone who is not informed should check out Squire Turbo Systems. I know the concept appears hoaky, but they really seem to work well!

        I've seen their turbo setups and they are really the main rear mount guys. The setups do work, true.

        Can a twin turbo setup be done on the LHD drive cars as well?
        It should fit easily considering there is no steering shaft in the left hand drive. Chris had mentioned they would make the twin available for LHD cars for people that wanted it.

        Good work. Will these kits be pro efi, or aem tuned kits? Which ever they are it will be worlds better then a chicken farmer based kit.
