Intake Turbulence w/ Turbo
I've been battling an upper RPM hesitation my Camaro is having. After having tried re tuning, ignition parts and other things I'm beginning to think it's turbulence in the intake manifold.
I replaced the stock plastic intake with a Victor JR fitted with an EFI "hat"; I'm wondering if that EFI hat and intake combination might be causing turbulence, thus causing hesitation. Anyone familiar with intake air dynamics on turbo systems? Last edited by Steve@HPE; 03-29-2012 at 10:02 PM. |

As far as why the Victor Jr didn't work well, it's hard to say, but my guess is turbulence and heat soak as you say. One odd thing we noticed was the car idled well and had decent street manners UNTIL the engine reached full operating temperature (i.e., the Victor Jr. became heat soaked). Then it sounded and felt as though the engine was missing. |

Went thru this before, what did the maf hertz look like? was it erratic? put the car in sd and see if the issue smoths out.

Never understood why any body would run a carb intake with efi. Different runner lengths, stupid elbow, and then the intake is aluminum.
I wish gm would of made the intake plastic on the vortec 8100's 50 pounds of aluminum |
