There are two turbos on the 300. One small and one bigger, right?

I think I've read somewhere that the boost should not be above 0,9 bar on the original turbos. But is that because of the small turbo? Is it possible for higher boost on the larger turbo?

THere are two identical sized turbo's on the zed, each turbo feeding one half of the V6 block. Sequential turbo cars like the supra have one small and one larger version for two staged boost.

 

Stock boost is 9psi / 0.62 bar. Turbo's are efficient up to around 16-18psi (1.1 - 1.2 bar), although you need bigger injectors and aftermarket intercoolers to run much past 14psi (1bar) which is the typical boost level most run theirs at as a safe level on stock turbo's and will give around 340-370 fwBHP.

You not thinking of a poopra :slap:

Can I ask why you would need aftermarket intercoolers, surley the charged air would be at the same temp whatever the boost

colder air more oxygen, less chance of det

the higher the compression ratio the higher the compressor outlet temp, also the higher boost you run the more inefficient your stock tubs so again higher charge temps
