I got my smoke system installed and working well except for getting smoke in the cockpit after about 20 seconds. I have read everything I can search out on the site regarding this. Lots of discussion on sealing cockpits, negative cockpit & tailcone pressure etc., but no reports of solutions. I would like to hear from anyone who has found a solution that allows for extended smoke time without a cockpit full of smoke. My plane is an RV4 with Vetterman 4 pipe exhaust.
