Advanced Induction System Tuning Seminar

Advanced Induction System Tuning

Adelaide Australia 2016


Update: AIST Seminar

We have looked at a couple venues for the Seminar in Adelaide on November 19th-20th but are waiting to see the total amount of people who will be attending. As of today we have 30 of the 80 people who pre-registered that have booked their seat with a down payment. In order to reserve the venue, catering, sound engineer and videographer in time we must have a final head count no later than April 25th. If you have registered but have yet to book your seat with a down payment, please do so before April 25th. We turn in our numbers on March 1st so we must regrettably stop any further sign ups after this date.

AIST 2016

I would like to thank everyone for the overwhelming interest in the 2016” AIST” seminar. Unlike previous seminars the one I will give in Australia in 2016 will be expanded and more in depth than any I have previously given along with some topics I have never covered before. A breakdown of some of the updated topics that will be covered are bullet listed below. The Seminars will be on the second and third weekends of November. We will be audio recording the Seminars (both of them) and the audio files from both seminars will be shipped to you free of charge. We will have assistants in the crowd with microphones so any and all questions and answers will be audio recorded. Each person can choose which seminar they would like to attend but some seating may have to be changed for various reasons so no assigned seating will be given. Once we receive your deposit and have booked your seat the seminar materials will be mailed to you 2-3 months prior to the seminar taking place, these materials include,


  • 100+ page book.
  • Various hand outs and informational materials.
  • Reher Morrison T-shirt, hats.
  • Thumb drive containing,
    • Audio files “Speed Talk interviews on engine building and air flow”
    • Reher Morrison Engine calculator, software demos and discounts on software during the show.
    • Spread sheets containing, Camshaft math, Air flow calculations, discharge coefficients and tuning equations. The equation list deals with a few of the following.
      • Helmholtz intake tract tuning.
      • Simplified multi order intake tract tuning.
      • Limiting port velocity.
      • Average, choke and peak cross sectional area.
      • Estimated total engine air flow.
      • Estimated carburetor size based on total engine air flow
      • Airflow demand at peak piston speed.
      • Port, manifold, throat valve area coefficients.
      • Area, air speed cfm/in² conversion factors
      • Discharge coefficient for any test pressure
      • Expansion ratios, compression ratios
      • Mean Gas Speed (Curtain, throat, valve, choke area)
      • Throat, choke convergence.
      • And many more

Expanded portion of presentation For Australia 2016.

  • The presentation will consist of over 200 slides, visuals and CFD videos. There will be CFD analysis of the air speed profile of the intake ports as well as certain intake manifold designs. CFD quickly and accurately gives a visual representation of what proper verse improper air speed profile looks like.
  • A more comprehensive break down of the math, physics, and phase changes involved in the intake tract.
  • Is supersonic flow possible in an intake or exhaust tract?
  • What is “Sub Sonic Choke” Discussion on different types of “Sub Sonic Choke” and there characteristics on the running engine.
  • Modern Pro Stock, Comp, “Unlimited NA engines” cylinder head design, and how it has changed with increased engine speeds.
  • Modern Pro Stock, Comp, “Unlimited NA engines” valve train design, and how it has changed with increased engine speeds.
  • Analyzing dyno data for insight into induction system tuning issues.
  • Matching the engines VE curve with induction wave/harmonic tuning.
  • Wave Amplitude manipulation or, “how to band aid a bad situation with air speed to the intake and exhaust tracts”.
  • How Low lift cams, street driven vehicles and engine speeds under 6500rpm drastically effect the overall design of the intake and exhaust tracts.
  • EFI tuning and manifold design changes associated with EFI. Differences in manifold and intake tract design for MFI verses EFI. Injector placement and its effects on power.
  • Variations in port, runner sizing and length due to supercharging, turbo charging or power adders such as nitrous and nitro.
  • The sound of any port is its heart beat. Smooth air flow increases power. Certain sounds and where they occur in the lift curve can point to specific design problems regardless of what the port flows.
  • How to use a Pitot tube and vortex generators to diagnose problem areas in an intake port in less than one minute!
