Intake Manifold Flow Tests: LS1, LS6, TBSS, BBK, Dorman LS2, 102 Fast LSXRT & more
- darn spell check....still we may have some interesting information coming soon
The Best V8 Stories One Small Block at Time

There might be another cathedral intake too not sure yet.
BTW - Let's please spare bashing any intakes, TB's or cylinder heads.
I don't want that type tone in the thread.
Even the lowly EGR less LS1 intake has its place - at least as a base line part to test or for someone on a very tight budget.
This thread is a marvel with all the scientific and educated info in it, no need to ruin it with flame wars. I highly appreciate the effort, dedication and money (!) that the author puts into this. And I'm still holding my fingers crossed that there will be a stock LS6 intake and a snout-modded LS6 intake in the next test run. I could provide the former if I wouldn't live in the old world over the big pond
The LS6 intake will have its day in testing

When the 99 TA gets the new 416, the old LS1 will be donating an LS6 intake for baseline testing. That will be part four is a few months away. That old EGR less LS1 intake will get used as a cover for the old LS1 while the LS6 gets tweaked with a 90mm snout and maybe even ported...thats the long term plan.
I've contacted the shop to set up flow testing hopefully in a week or so we will have data. The intake will be tested with my Reher-Morrison ported LS3 heads as per prior test process.
I think the RC RR LS3 looks good!
If someone wants wants to provide an adapter that LS3 intake on cathedral head flow test can happen...
