Think this intake swap will hurt performance?

I'm just a bit too fast for the class I run and have to slow it down to keep from breaking out of the 7.65/12.00 cutoff. So maybe there is a benefit to it. I broke out yesterday with an 11.96 in the 2nd round as a matter of fact (trying to make up for a bad. 051 light).

The irs (should) be just fine. I don't think my car's 60 ft times are violent enough to be a problem. There are a few other guys with the same setup hitting it much harder than me. If you watch video of my car launching it really looks tame. The trans is also built to run in a turbo application.

I thought about trying some sort of two-step but they are not allowed in any of the classes I run.
