Excessive Turbo Lag on My 2024 NSX Type S - Is This Normal?

Vehicle: 2024 Acura NSX Type S

Hi all,

I just picked up my new 2024 Acura NSX Type S a few weeks ago, and I'm loving it for the most part. However, I'm noticing what feels like excessive turbo lag, especially when I try to accelerate from a low RPM or from a near stop. There's a noticeable delay before the power really kicks in, more so than I expected from a twin-turbo V6 with electric assist.

It feels like I have to really wind it up before the boost comes on strong. I've tried different drive modes, but the characteristic remains. Is this a normal trait for the NSX Type S, or could there be something amiss? I'm coming from other performance cars, and this lag feels a bit pronounced.

Any other 2024 Type S owners experiencing this, or have any insights into the power delivery characteristics? Thanks for any feedback!

ClearTheCode admin answer:

While some degree of turbo lag is inherent in turbocharged engines, excessive or noticeable lag in a high-performance hybrid like your 2024 Acura NSX Type S, especially with its electric motor assist, warrants investigation. Here are potential causes:

  1. Boost Leak: A leak in the intake system (e.g., intercooler piping, vacuum lines, blow-off valve) can prevent the turbos from building full boost, leading to delayed and reduced power. This is a common cause of turbo lag.
  2. Wastegate Issues: The wastegate controls exhaust gas flow to the turbocharger. If it's stuck open or malfunctioning, the turbos won't spool up efficiently, causing lag. This could be mechanical or an issue with its electronic control.
  3. Sensor Malfunction: Sensors like the Manifold Absolute Pressure (MAP) sensor, Mass Air Flow (MAF) sensor, or oxygen sensors provide critical data to the Engine Control Unit (ECU). Incorrect readings can lead to improper fuel-air mixture and ignition timing, affecting turbo performance.
  4. Ignition System: Worn spark plugs or faulty ignition coils can cause misfires, leading to incomplete combustion and reduced engine efficiency, which can manifest as perceived lag or reduced power.
  5. ECU Tuning/Software: While unlikely in a brand-new vehicle unless modified, an improper ECU tune or a software glitch could affect boost control and power delivery. Ensure your vehicle's software is up to date.
  6. Fuel System: Issues with fuel pressure or injector performance can also impact engine power and responsiveness.

When to See a Shop:

Given that your 2024 NSX Type S is brand new, it's best to contact your Acura dealership immediately. They can perform a comprehensive diagnostic scan for any pending or active trouble codes (e.g., P0299 - Turbocharger/Supercharger Underboost, P03xx - Misfire codes), check for boost leaks using specialized equipment, and verify all engine parameters are within specification. Do not attempt to modify or 'tune' the vehicle yourself, as this could void your warranty and potentially cause further damage.
