It would put it somewhere between S58 and S55. The pro to a smaller turbo is less lag, the con is usually less top end power. S58's power delivery is a product of its design - lower compression ratio + bigger turbos = more power and top end at the expense of boost threshold and lag. S55 is about response, not pure power - hence the perceived "spikiness" and why tuning its top end is very hard on stock turbos. S58 is about power, specifically in the upper half of the tach. Which is more linear or NA feeling? Well I would say S55 has a more NA-like throttle response while S58 has a more NA-like power band.
What would really be a game changer would be fitting an e-turbo to S58 which would always ensure the turbos are pre-spooled which would give it insane response and maintain the more linear power band! |
