This small mod will add twin turbos to v8 engines. [Turbo PSI] Stage 1 38psi Stage 2 49psi Stage 3 60psi Stage 3.5 (antilag) 65psi Stage 4 (Drag Turbos) 160psi
they look like fairly decent sized turbos in the model, so if your "stage 1" is using 38psi, you might need to make them 'bigger' in your .jbeam, and lower the boost pressure to compensate. this goes for all of them. compare the ETK turbos to the Bolide Corse turbos if you need help with them, also go to the "Turbochargers" wiki page. BUT.... i could be wrong, and your stage 1 could be super duper powerful with 38psi in 2 large turbos, and they would only get crazier after that. just a bit of constructive criticism is all.
