hodge Posted August 28, 2013 Share Posted August 28, 2013 Had the Supra out for an hour or so tonight for a bit of spirited driving. Had a nice easy drive home, to cool it down with a big grin on my face, and parked it up in the garage. Jumped in it to take it to work, on the way I fancied a bit of the rolling anti-lag. 2nd gear, button in, foot on the floor aaaaaaand ooooofffffff. Good job I was watching the boost gauge. My boost went off the gauge, well over 2 bar. Quickly lifted off the throttle before I let the button go. I recon that could have been pretty much carostrophic seems it's only mapped to 1.8 bar. All my lines are braided Teflon and insulated with thermosleeve but I'm guessing the heat and got to 1 of them and melted it. I'll pull them all off tomorrow and take a look. Think I might go back to silicon wastegate lines, and thermosleeve then to see if they take heat any better. Quote Link to comment Share on other sites More sharing options...
mellonman Posted August 29, 2013 Share Posted August 29, 2013 could be the boost solinoid, intresting to find out if the braided lines have failed so quickly also i would of thought that ryan would have a map to at least 2 bar on your car even though your running at 1.8 even if it was just pulling extra timing and dumping fuel in Quote Link to comment Share on other sites More sharing options...
JamieP Posted August 29, 2013 Share Posted August 29, 2013 Might be just a boost spike because of using the boost builder button, I'd try doing a in gear pull before you tear it apart. Quote Link to comment Share on other sites More sharing options...

Does the same in gear, boost keeps rising. Quote Link to comment Share on other sites More sharing options...

I'll pull the lines off tonight and take a look. Quote Link to comment Share on other sites More sharing options...
Lee P Posted August 29, 2013 Share Posted August 29, 2013 On my car I had to use silicone hose instead of braided. With the twins it was so tight that braided line would get too hot and melted the pipe internals Quote Link to comment Share on other sites More sharing options...
add heywood Posted August 29, 2013 Share Posted August 29, 2013 I thought the syvecs would have pulled the spark or at least do something to stop the boost... Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted August 29, 2013 Share Posted August 29, 2013 I thought the syvecs would have pulled the spark or at least do something to stop the boost... Maybe it can't when your using the rolling anti lag? As that's weird and also would have thought the syvecs would have done something to stop the car overboosting.

Rob_Mitchell Posted August 29, 2013 Share Posted August 29, 2013 Does the same in gear! so its the same either way. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 29, 2013 Share Posted August 29, 2013 Why did the ECU allow it to over boost? My Motecs try to reduce boost but if it goes more than 5% over the top limit it kills the fuel until it drops right back down. Needs the safety features setting up, it should be impossible for that to occur. Hope it's not detted! Quote Link to comment Share on other sites More sharing options...
Lee P Posted August 29, 2013 Share Posted August 29, 2013 The boost cut is obviously not set low enough, Syvecs will do it Quote Link to comment Share on other sites More sharing options...
hodge Posted August 29, 2013 Author Share Posted August 29, 2013 I've been trying to get in touch with Ryan for the last 3 weeks now, I've emailed and called him and he's not answering or replying at all. I need my idle control valve turned back on, a voltage trip incase the alternator overcharges so I don't fry my battery and also lower the boost cut trip or set it up 1 or the other. I'll order myself a few metres of silicon hose today and get the car all piped up with that to save anything melting again. Quote Link to comment Share on other sites More sharing options...
skippyboyo1 Posted August 29, 2013 Share Posted August 29, 2013 Love the "blast to work". I learned the hard way driving cars that I had for sale! Something always goes wrong. Quote Link to comment Share on other sites More sharing options...
hodge Posted August 29, 2013 Author Share Posted August 29, 2013 Love the "blast to work". I learned the hard way driving cars that I had for sale! Something always goes wrong. Nothing major, the car drives perfectly apart from that, I'm going to order some hose today. But your right about the "something goes wrong thing". It's as if the car doesn't want to go, it wants to stay with me forever. Quote Link to comment Share on other sites More sharing options...

Needs the safety features setting up, it should be impossible for that to occur. Hope it's not detted! No chance of that Chris, I instantly let off the throttle and when I tried it just with the gears I did it in low boost setting at 0.9 bar, I let it raise to 1.5 bar and backed off. I think the problem lies in the lines that run between the downpipe and manifold. Although I've got loads of heat wrap on there and the pipes are thermosleeved it's just not enough for the heat.

hodge Posted August 29, 2013 Author Share Posted August 29, 2013 Haven't had time to get onto this today but they'll come to bits tomorrow regardless of what ever else I have on. I've got someone coming to view the car soon so I need it all in perfect working order and Shiney clean. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 29, 2013 Share Posted August 29, 2013 You aren't selling it after all your work, surely? Still, if the price is right... Quote Link to comment Share on other sites More sharing options...
