StuartW Posted November 19, 2011 Share Posted November 19, 2011 Hi all i am building my white sup back to BPU and 7 years ago i crashed my BPU TT6 becuase the trac control used to cut too much power when you booted it, the green light would come up and the trac motor would close the throttle body down so much you lost any momentum which was dangerous when overtaking etc. so i turned it off and it spat me off the road (pics in my garage) I wondered if i cut away say 20% of the butterfly weather it would reduce the severity of this affect? i figure the trac motor just could not react any quicker.. has anyone overcome this @ around 390hp on j spec ceramics? i am fitting a closer ratio w58 so it will be even more of a problem now i reckon? Cheers Quote Link to comment Share on other sites More sharing options...
dude Posted November 19, 2011 Share Posted November 19, 2011 so i turned it off and it spat me off the road (pics in my garage) Shouldn't go driving these powerful cars if you can't handle em dude !!!!:d:innocent: Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted November 19, 2011 Share Posted November 19, 2011 Yep, mine cuts in if I boot it on full boost. Usually in 3rd around 6k. Wasn't sure what to do about it, hasn't been too agressive but judging from what you've said I've been lucky. Toying with getting a RLTC Quote Link to comment Share on other sites More sharing options...

StuartW Posted November 19, 2011 Author Share Posted November 19, 2011 Or we can back the throttle off to half travel !!!! Yes a throttle stop may be the solution!

mark newman Posted November 19, 2011 Share Posted November 19, 2011 Are you fitting RLTC onto your new race car stu ? Quote Link to comment Share on other sites More sharing options...
dude Posted November 19, 2011 Share Posted November 19, 2011 Are you fitting RLTC onto your new race car stu ? Only a girl would even think about traction on a drag car !!!! Quote Link to comment Share on other sites More sharing options...
StuartW Posted November 19, 2011 Author Share Posted November 19, 2011 Are you fitting RLTC onto your new race car stu ? NO but i will be developing the Syvecs S8 Traction control with Ryan...Just for when i am still a bit sleepy..ya know..heavy night n all ;-) This will be tricky as i am hoping the front wheels wont be on the ground too much! The other otion was a "G" sensor but probably even trickier!! Quote Link to comment Share on other sites More sharing options...
mark newman Posted November 19, 2011 Share Posted November 19, 2011 Oh yes top turn and the pit area. good thinking. Quote Link to comment Share on other sites More sharing options...
Josh Posted November 19, 2011 Share Posted November 19, 2011 I love not having any traction control. I think if I did, I'd just turn it off every time I drove anyway. Quote Link to comment Share on other sites More sharing options...

Cheers Why would you want to run the std trac control anyway? it was one of the first things i disabled when i got my Supra, they are so primitive anyway, almost useless and dangerous, as you found out, quite soon i just remove the butterfly from the throttle body and welded up the holes.

spikedjack Posted November 19, 2011 Share Posted November 19, 2011 turn the trac off, and balance the throttle better when cornering is my advice, hitting second turbo violently caught me out when i first bought mine too, luckily enough i kept my foot in, and just came out of it with a pair of brown soggy boxer shorts Quote Link to comment Share on other sites More sharing options...
Branners Posted November 19, 2011 Share Posted November 19, 2011 And I believe the original question was whether he can fix the problem by changing the size of the throttle butterfuly rather than chance his arm on catching a tank slapper on a cold wet night?

Personally i would rather take my Chance's with no supra trac control with 500BHP, than rely on the std, having experienced just what its capable of, hence my answer. As for cutting down the trac butterfly in a vain effort to try and improve on an already frankly crap and dangerous system, is IMO foolhardy.

More dangerous that losing the back end at 50mph when you go across a white line and ripping the car to pieces on a barrier? I store up pictures of cars that have been written off by forum members (mostly so I can prove it was destroyed when it reappears after a shody rebuild) and it is only the sheer strength of the car that keeps us from losing more members each year. Feel free to run your own car with no TC at all, but if somebody wants some level of safety on their car lets not try and pursuade them otherwise.
