Guest Jason1 Posted May 28, 2014 Share Posted May 28, 2014 There are many versions of this floating around Can I just tie back the Exhaust valve and the valve on the inlet ( top of engine)? Will this do the conversion or do I have to remove and plug pipes as well? Wanting to TTC mine to rule out any turbo problems before I fit the AVCR I will leave it in TTC mode and use the controller to control the boost and hopefully bring them on a little sooner Many thanks Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted May 28, 2014 Share Posted May 28, 2014 Here's the link, I followed this to test out TTC mode http://mkiv.supras.org.nz/articles/andy.htm There's alot of useful information within the forum, and sometimes all it takes is to use the search bar Quote Link to comment Share on other sites More sharing options...
Guest Jason1 Posted May 28, 2014 Share Posted May 28, 2014 Thanks I will take a look Did use the search but so many versions just want one that works (proven) before I disturb anything Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted May 28, 2014 Share Posted May 28, 2014 I think there's a ETTC but they's a lot of work. The quickest way is the link I posted, literally is 5min job. If you want a hand I be happy to help, I also have pictures of my TTC pumped in, when I was using TTC to problem find on my Supra. Quote Link to comment Share on other sites More sharing options...
masterfett Posted May 28, 2014 Share Posted May 28, 2014 is it really worth doing though? is it just a matter of personal preference..? Quote Link to comment Share on other sites More sharing options...
Guest Jason1 Posted May 28, 2014 Share Posted May 28, 2014 It is preference but handy to see if there is problems in the setup Ok have carried out the TTC mod as above, an been out for a spin Did 6 or so good pulls and the car does seem smoother and the boost is nice and progressive However the car boosts to 1.2 bar the straight away drops to .8 bar and stays there is this right? It really pulls hard to 1.2 then a little stutter and down to .8 bar I don't know if this is correct holds at.8 though no problem. Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted May 28, 2014 Share Posted May 28, 2014 is it really worth doing though? is it just a matter of personal preference..? I only did it to problem find for my Supra. Its only worth doing if you have support mods and a remap. I didn't like it too much because the sounds from my stainless exhaust has was killing me lol, I was too loud. But I guess if TTC is done properly it will and should feel like a small single. Quote Link to comment Share on other sites More sharing options...
Guest Jason1 Posted May 28, 2014 Share Posted May 28, 2014 Also I have noticed when I got back the top valve was closed when the engine idling couldn't see the exhaust valve so not sure on that one. I thought it kept the valves open? Quote Link to comment Share on other sites More sharing options...
Guest Jason1 Posted May 29, 2014 Share Posted May 29, 2014 We'll all sorted I think After the ttc mod which shows everything is working Turbo wise I have now put it back to normal and for some reason it all works great I can feel the 2nd turbo kick in and at.9 bar on full chat and pulling great no smoke nothing I am making a restrictor ring so exhaust will Be fully swapped out this weekend I shall see we are at then as will be full 3" system apart from front pipe which will be 2 1/2" with a 2" restrictor ring Any ideas what the boost should be with that done Just so I can check hoping for at least 1 bar Quote Link to comment Share on other sites More sharing options...

listy Posted May 29, 2014 Share Posted May 29, 2014 Is your car a BPU? This. If you have not heard of BPU, then click the blue text, then do a search. Quote Link to comment Share on other sites More sharing options...
