Customer came in requesting a dumptube to be made for his Rx7. He recently rebuilt this engine and upgraded the turbo. Now with the new Precision turbo the old 38mm gate could no longer hold boost properly. So he upgraded to a Tial 44mm gate

Not having a proper dumptube for your turbo setup can potentially cause serious damage !

For example: If these vacuumm lines below wouldve been melted the gate would no longer open to expell the excess exhaust gases. That would result in a lean out situation and melt a piston, crack a sleeve, etc.



Now some pics of his new Proven Power dumptube !
