Cheap Alternative for LT1 Opti Issues

I think that’s a lot more physics theory than practical impact. Have a look at the OE LS air inlet system upstream of the TB and tell me it conforms with any known guidance on things like diameters of straight pipe upstream of the maf, avoiding large cross sectional changes, or non smooth profiles.

Disrupting/changing the airflow for the MAF can definitely have an impact. When Glenn and I were first working on a restrictor for the LS he made one that we put right in front of the MAF. Car wouldn't rev or pull about about 2,000-2,500.
I just have practical experience-no thermal velocity dynamics theory and it's impact on turbulence in a sphere of tubing. Where's my Bud Light Cody?

Putting a restrictor immediately in front of the maf is a bit extreme when talking about air inlet design not mattering. I was considering reasonable things like 3.5 vs 4” tubing, a 90 vs a 45 etc.
