Is an exhaust driven E-Vac system worth the effort? What, if any, tips/pit falls has anyone heard about?
Thanks
Bruce

BRUCE:
ANY TIME YOU CAN TAKE PRESSURE OUT OF AN ENGINE IT IS A BIG HELP. I USE THE EXHAUST
E-VAC SYSTEM ON MY RACE CAR AND IT WORKS WELL. THE ONLY THING YOU HAVE TO CHECK EVERY SO OFTEN IS THE "CHECK VALVES" TO MAKE SURE THEY WORKING. THE RUBBER IN THE CHECK VALVE GETS HARD FROM THE HEAT.

Does this type of system work on a car with full exhaust?

Thanks for the tip on the check valves.
I am using this type E-Vac system on my full exhaust car, but when I disconnect the exhaust it also works.
