willeng,
This is true, low flow, high PR compressor flow instability.
My video cam (Sony) crapped or I would have been able to video a rare event on the engine dyno.
No misconception here.
willeng,
The problem is that peak Trq is at approx 22lbs/min with these cams. Trying to de-tune in this flow region is counter productive. I could decrease cylinder pressure in that region, but that is self-defeating.
I have Motec M800 that I am using and it has maxed out "outputs", I was...
jbond,
I have a set of the 743347-1 on the way.
The engine I am testing has a prototype split plenum on a 3.0L V6 and a camset that was specifically ground to max exhaust energy to minimize boost threshold and maintain the exhaust energy to the max RPM.
The peak Trq is approx 22lbs/min and the...
willeng,
Thanks for sharing. I know that reverse engineering is not the "noble" thing to do, but I think if I see consistency in the placement relationship it may make my chance of first attempt success increase. This is a twin parallel setup, so the cost rises fast. I am testing in a engine...

I am considering an attempt to convert a comp housing from a Garrett GT2871R (472560-15) for anti-surge. The comp housing is a "GT28R" style.
I am trying to operate this unit with the following comp map points.
Flow: 20%=7, 50%=16 and 100%=38 lbs/min respectively @ a...
Mike,
"To partially answer your question, you should be able to make a map of how the resonances move around with boost, by adjusting for changes in the speed of sound within the intake tract as the boost changes."
The assumption would be that the Hemholtz resonance as applied to normally...
Mike,
The One Lap of America is a event sponsored by Tire Rack. The competition consist of multiple events including road courses, wet/dry skid pad and drag strip. The cars are driven on the road between event sites.

Greetings,
After completeing a search through the SAE docs and reference texts of Blair, Winterbone, Peterson, Horlock, Bell and the Wave Action simulators I am forced to ask the above question.
Forced Induction Intake Manifold Tuning, does it exist?
As the subject content implies I am in...
