Question: 2g JMFab SMIM and BC272 gains..

[scottsee]

Currious what others have experienced from these two bolt on's. I just bought the SMIM and have the cams sitting on my desk. I won't be installing these for a month or 2, but I was wondering what kind of airlflow increase to expect. Last year I pulled out a 12.4 @ 111mph at 21psi, and 33lbmin and a crappy tune neting me 13-14deg timing advance. What results did you guys net with these mods?

Thanks guys..

Ps. If any has some DSMlink logs of before and after, I'd be stoked. No one could hook me up in the Link forum.

Thats pretty weird that you trapped 111mph with only 33lb/min. On the time you see under my username, DSMlink record 39.3lb/min. This is on a big 16g and 23pis. My head is ported and I have BC 272's. Prior to the head swap, my max flow rate was like 35lb/min.

airflow was inflated and shows 35lb. But if you look at the BoostEst/33bar you can see the discrepency.

Before/after logs with Bc272 or JMFab SMIM anyone??
