celicamad Forums Junkie Location: newcastle Registered: June 2002	Re: 1jz twin dump pipes Tue, 04 May 2004 12:57 umm reducing lag well not entirly correct look at it this way full boost is achieved MUCH sooner . is the rpm at which boost is first noticed is changed ? well i actually cant remember the larger the volume after the dumps the better the response and the less heat retained .less heat also equals more power as engnine bay temps drop ...CONSIDERABLY thats why i run twin 2.5 inch dumps which eventually run into a single 3 inch just past the gearbox. This not ideal i really should run 3.5 inch but noise is a factor in the family car running more boost is subject to removing flow restrictions such as plumbing and stock intercooler .just doing these mods increases boost by around 2 psi . with dump pipes you should be able to safely run 16 psi all day . i have for 30,000 klms when you combine dumps with my boost controller this capitalises on the turbos new found abilty to spool EVEN faster .my wifes Cressida is on 16 psi by 2800 rpm . and weighing 1690 kgs at dubbo (with me and a FULL boot)it ran 8.58 on the 8th mile .i think posibly the only 1j Cressida to ever run under 9 sec at dubbo??? no hks cam wheels stock ecu stock intercooler plumbing what im getting at is the mid range torque is what is making the twin pipes so successful. but without my controller my car is 1/2 a second slower i doubt my peak power figure is as high as some [Updated on: Tue, 04 May 2004 13:00] [Report message to a moderator]
