SVS Turbo
Enthusiast
We recently made some changes to the rear mount turbo system that we have been testing on a Gen2 Viper.
We changed the compressor outlet piping from 2.5" to 3" and then made it Y into (2) 2.5" pipes to the bottom of the intercooler. From the top of the intercooler we added (2) 2.5" pipes w/ 2 BOV's to the intake manifold instead of only 1 pipe and 1 BOV that made a Y into the intake manifold. For the intake on the compressor we were able to increase the piping to 4" and up to 5" at the air filter.
Currently the engine bottom end is built and 8.5:1 compression. The heads are similar to a stage 3 stock ported/polished head with bigger valves and roller rockers. We’re running a Motec EMS along with coil on plug ignition.
There's also a set of SVS headers with 3" exhaust back (no cats)
We maxed out the fuel system (and kept it at a safe level) using 55lb side feed injectors. We have an extra Bosch fuel pump added to the stock fuel pump along with regulator, bigger lines and a return system. We made 830rwhp and 870rwtq @ 12-13psi tuning with E85. The single 76mm turbo in this system is capable of a great deal more power and boost.
We have started to work at creating the SVS rear mount turbo system into a kit that will be capable of 1000hp+ and if everything falls into place it will cost under $10,000
We have control of the boost from 4-13psi so this system could be added onto a cast piston year viper.
It’s highly possible that this turbo kit will become a 1000hp Gen2 Viper complete solution with AEM, fuel system for under $15,000 (tuning and installation not included)
