Another Mopar Off My Bucket List - Barracuda Fastback

It's funny you doing this. I have been working on a boat with inter cooled blowers. They have a specially made intake for a core inserted into it. This particular system was built 20? years ago? One of the cores started leaking, we took the cores out and retuned. It's alright when the engine is stone cold, but even after warm up, and the engines only get to about 160ish, it's a pig. No power. The reason we didn't put another core in was because this particular size is no longer made. I also have to believe that this core size doesn't do very well because of it's small size. This particular boat is fuel injected so the manifold isn't typical. It's taller than a regular blower intake so we can't add a 4" inter cooler. No belt that long.
Looking at your recent post, I would have stopped you before you modded the intake. The only way you get an "efficient" inter cooler is to add the 4". The small amount you would add to the intake, isn't going to work. Sorry man.
