Fast 102 VS LS3

Fast 102 VS LS3
Looking for some flow data. I recently flowed my new set of LS3 heads.... Also flowed them with the stock LS3 intake bolted to them. I was shocked to see how much cfm was lost with the intake attached. I'm looking for the same data but done with a FAST 102. Basically looking to prove to myself if it's worth buying a FAST.... Having a hard time with accepting leaving all that on the table.

I don't have any direct data, but maybe these links will help. You might want to look into the Rick Crawford Racing ported LS3 intake (another vendor was approved to sell the design also but I've forgotten their name) as a less expensive version of the FAST102 with pretty similar, if not better, results for the cost.

You'll need to interpret the RCR L76/LS3 intake flow number results in the first post:

Haven't had this intake on the dyno yet but I did test it back to back at the track VS a Rick Crawford manifold. This intake picked up 1.5 mph with no other changes. This intake definitely feels like it has more grunt down low but I worry that the loss of plenum volume will hurt the top with my ported heads that I'm about to install.

The data provided was done with a Crawford intake. I have since re-done another intake for more port opening transition which has helped and gained 1.5 mph at the track vs the RCR manifold.
The data I'm looking for is a Fast intake bolted to a set of ported heads to get the CFM loss from the intake alone. I'm not debating the gains of the RCR manifold I have already taken that to the next level and got more performance with the intake above.
Now I'm focused on how to minimize the CFM loss.

The ls3 heads flow very similar to stock ls3 heads. Once you port the heads it becomes more of a restriction.
That's where the fast starts to take over. It flows more like ported ls3 heads

Did you ever find the desired data? You may be interested in this link, starting at post 216.
