These are installation Procedures for eliminating the boost vacuum leak in the Dart. There is NO check valve which means that this a direct boost leak. This is the reason for laggy boost and boost dropping off on the top end. This HOW TO is compliments of Blitzkrieg as being the first author to post about this solution and also to Blitzkrieg, SF18C, and mackzilla for pictures of their setups. If anyone attempts this and cares to upload pictures for each step or cares to elaborate on the steps in more detail, we will add them as we go along.
1. Remove the cover off the engine and take a look at the charge pipe on the Driver's side.
2. After removal of the turbo cover, you should see the MAF sensor and the 3/8" vacuum line just prior to it. If you follow this line you will see that it goes to a Tee. One side goes to the intake manifold (I believe) and the other goes to the intake just prior to the turbo.
3. Remove the hose on the charge pipe (driver's side).
4. Place a rubber/plastic cap on the tube then placed the hose back on it. This effectively blocks off the flow.
***In the words of Blitzkrieg, "Now there is more TQ down low with a quicker spool and more HP up top with no boost leaks."
He also checked the Abarth and there IS a check valve in place. No check engine lights or issues have been reported since making this change.
Here are a few different setups of the same solution.
