What is the PSI for Stage 1 MHD N54?
Stage 1 Maps Each with 4 octane Variants (US OCT ACN91, 91, 93, 95 / RON 93, 95, 98, 102) using a peak of 15 to 17 PSI tapering to 10-12 PSI at redline. Stage 2 Maps Eight maps included Stage 2 (High-Flow Downpipes) and Stage 2+ FMIC(DPs and upgraded FMIC recommended). Each with 4 octane Variants (US OCT ACN91, 91, 93, 95 / RON 93, 95, 98, 102) using a peak of 16 to 18 PSI tapering to 12-14 PSI at redline.Stage 2 (up to 380HP/560NM) – 91oct/95ron, 93oct/98ron, 95oct/102ron, high-flow downpipes recommended. Stage 2+ (up to 420HP/650NM) – 91oct/95ron, 93oct/98ron, 95oct/102ron, high-flow downpipes + FMIC recommended.
How to get 600hp N55?
With full bolt ons, fueling modifications, port-fuel injection, an upgraded turbocharger, and a custom tune, you can expect to achieve upwards of 600 horsepower. Opt for a 58–62 mm turbo. Quick spool, strong midrange torque, and street-friendly response. High Power Builds (700–900+ whp): You’ll be looking at 67+ mm.Running the motor at 10 psi with the 60mm turbo resulted in 575 rwhp. Replacing the smaller 60mm turbo with a larger 67mm one resulted in a jump in peak power from 575 hp to 604 hp at the same 10 psi of boost.
How much HP can an N54 handle?
The N54 on stock internals should be left around no more than 600whp/wtq. Anything beyond that to about 850whp should have at a minimum upgraded pistons and rods and better bearings. Beyond that you start looking into closed decks and etc. This is for longevity. Performance Catback Exhaust: Upgrade to a high-performance catback exhaust system to optimize exhaust flow and maximize power gains for your N54. Upgraded PCV Valve: Swap out the worn-out plastic factory PCV valve with a reliable all-aluminum upgraded component, ensuring additional durability as you chase more power.
How much horsepower can the N54 handle?
The N54 on stock internals should be left around no more than 600whp/wtq. Anything beyond that to about 850whp should have at a minimum upgraded pistons and rods and better bearings. The twin turbos setup gives it smooth power delivery and a ton of midrange torque, which makes the car feel fast even in stock form. If you’re modifying, you can get a lot out of the N54 with simple bolt ons and a tune.
