mattysupra Posted October 29, 2007 Share Posted October 29, 2007 And what does it do or go? Completly lost on what your all talking about:dontget: Link to comment Share on other sites More sharing options...
edge Posted October 29, 2007 Share Posted October 29, 2007 When the cats are taken out the boost on j-specs can run dangerously high, so a ring (basicly a big washer with set size hole in it) goes in where the decat pipes join up and keeps the boost from going silly high.

mattysupra Posted October 29, 2007 Author Share Posted October 29, 2007 The search button is your friend! Ye i know but couldn't find what i was looking for. Anyway my question has been answered! But im a bit confused as my car does about 1.1 bar of boost and after removing both cats and not fitting a restrictor ring it still does the same boost. Why is this? Maybe some thing else restricting it in the exhaust? Dont think it is tho as custom made exhaust with to cats or silencers at all. It has a blitz back box but there are no baffels in there as been removed. And the strange thing is that the car is still quiet compared to all other supras i have been in.

mattysupra Posted October 29, 2007 Author Share Posted October 29, 2007 mine has been with no cats for about 4 years now. I run nitrous on it and have done alot drag and track days in it over the years. I also drive it very hard (well untill the major brake fade kicks in) Have never had any problems. I also dont understand peoples drag times for there mods. I have run 11.9 in mine but sit more on a consistant 12.2-12.3. I look at every one else bhp which must be more than mine but seem to be in the 13-14 second quarter times. Why is this? i dont understand. Is it pure driver error with lack of control or what. I see dino results of 500hp and still slower. I would guess mine is 400-450 at a push with the nos. What sort of bhp is needed to run 12.3 seconds?
