The first batch of flow bench results are in..
FROM BOB :
Okay, semi-stock low-port tests are complete.
No surprise, but your intake did well here.
Better than stock 2-bbl intake.
Better than Steinmetz angled SSD intake.
Better than my ported Cannon 2-bbl Holley intake.
Better than stock EFI intake by a tiny bit.
Tiny bit less flow than an as-cast Cannon Dual Side Draft intake.
If you want peak flow numbers, here they all are at .500" lift.
(1.5 head with 1.65"/1.34" valves and bowls blended) - 99 cfm
Stock 2-bbl intake - 89 cfm
Stock 1.9 EFI intake - 93 cfm
Steinmetz angled SSD - 77 cfm
Cannon 2-bbl (ported) - 88.5 cfm
Stock Cannon DSD intake - 95 cfm
Goin Manta EFI intake - 93.5 cfm
Nothing to be ashamed of for sure. Good job!
The interesting thing, I think, will be on my big-valve race ported 1.9 head. I'm pretty confident your intake will do better than ALL the others here. My mild street low-port 1.5 head is pretty indicative of a standard Euro 2.0 head, or a 1.9 head with 1.72/1.50 Chevy valves with ZERO porting. So while a bad intake will show itself easily, a good intake hasn't had a chance yet to stretch its' legs out yet. My opinion anyway. Based on experience and gut feeling. Guess we'll see tomorrow! This took way longer than I thought, lol.
