s4 vs s5... twin scroll vs old spool
ok so i know the s4 is stronger in pretty much every other department and light, but the s5 has all the creature comforts and looks better (to me). however when it comes down both can do what.. like 350 on the stock turbo ? so if a sw4 with 350 and a s5 with 350 went at it.. the twin scroll system really wouldent make a flip would it ?

your not going to make 350hp on the stock turbo. It runs out of breath at the psi you need to make that power.
you are going to need at bnr stage 2 or stage 3. I don't know about the twin scroll. I still haven't found out what Brian at bnr reccommends. also power and response is a direct result of tuning. the s5 should be faster response because of higher comp rotors but these factors can be mitigated |
ahhh so what is the stock turbo rated at ? i was always told about 350 hp'ish.

This is also terrible stress on the stock turbo because it doesn't have upgraded seals or a 360 bearing which you can get with the BNR or majestic upgrade. |
doesnt haltech have a piggy back that works with the s5 ?
