kubus1 Posted March 31, 2003 Share Posted March 31, 2003 Guys, What in your opinion should be done to the engine before going for NOS? Its a TT with 60K miles with regular services done. Is there anything that I need to make sure is done so I dont end up with the bits of engine getting killed? Thanks for all replies, Cuba Quote Link to comment Share on other sites More sharing options...
dude Posted April 1, 2003 Share Posted April 1, 2003 How big a shot are you looking at , to do it properley you want to look at a progressive controller . John:flame Dev Quote Link to comment Share on other sites More sharing options...
kubus1 Posted April 1, 2003 Author Share Posted April 1, 2003 Nothing crazy, I just want to eliminate my off the line delay. I was thinking 50 to 100 hp. Cuba Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 1, 2003 Share Posted April 1, 2003 Be very very careful, nitrous takes no prisoners, it's SO easy to det an engine to instant destruction, especially turbo ones. Quote Link to comment Share on other sites More sharing options...
Branners Posted April 1, 2003 Share Posted April 1, 2003 a nice heartwarming story about NOS from the NZ Supra mail list Yeah, a few downcast looks on Sunday after the crash- we didn't join the convoy as we were all too tired and were driving a rental Hiace Diesel van (which it is rumoured still did pretty impressive drifting round Hagley park roundabouts) but no-one was talking much about what happened. The Skyline made only 1 full track pass- we had to wait for the weather to clear- once it came off the short patch of VHT it got wild and sideways, lurching left, then right, then left, then right, all under NOS'd power, until Glenn had to button back in both 2nd and 5th to avoid the wall- the last swing took up almost all of the track. I was standing behind videotaping, at once point I dropped the camera to watch, you can hear Alastair (Stalker) next to me going "Fuuuuuuuuuuuucccccccccc..................." as we were ceratin he was going to collect the wall. He didn't, still ran a 9.32 ET..............big balls, that boy. The next run, later in the afternoon, some confusion amongst the marshals about where he could stage a burnout- in the resulting indecision, Glen decided to go anyway, but he thinks he must have nudged the NOS button while going for the line-lock- result- BANG, the bonnet flies apart and up, indicator lens and grille fire out the front, rivets on the carbonfibre blanking panels popped out, and a huge cloud of NOS pours out. The explosion split the plenum chamber apart like a banana skin. Impressive, but not as damaging as you would think from watching it. We're up for a new plenum and manifold, some NOS fittings, a new bonnet.... and we'll be out racing again. I got video from the side of the explosion- I'll post the stills on our website later this week and will show the video on the Bad Boys Toys show next week on TV4. Home James at that point. Had a great time though, we'll certainly do it again. Quote Link to comment Share on other sites More sharing options...
kubus1 Posted April 1, 2003 Author Share Posted April 1, 2003 Right, So Chris, you're saying that NOS is a no no? What else can I do to get me quicker off the line, at the moment its great when the turbos kick in, but it jsut doesnt seem so fast before that.

MONKEYmark Posted April 1, 2003 Share Posted April 1, 2003 a torque convertor is supposed to be a great mod for off the line, you could also think about going for better gear ratios than the standard auto you have do you mean for drag racing off the line Quote Link to comment Share on other sites More sharing options...
kubus1 Posted April 1, 2003 Author Share Posted April 1, 2003 Mark, Its just for normal street driving and when you sometimes get the urge to blast off the treffic lights. Where can I find more info on the torque convertors? Thanks Cuba Quote Link to comment Share on other sites More sharing options...
Suprash Posted April 1, 2003 Share Posted April 1, 2003 Kubus, let me know if you fiond anything regarding the torque convertor. Another way to get quicker accelleration of the line is lightened flywheel, allowing the engine to rev quicker....... Quote Link to comment Share on other sites More sharing options...
Supra Pilot Posted April 1, 2003 Share Posted April 1, 2003 Ashley, You have a MANUAL, so a 'torque convertor' won't be of use to you. Also a lightened 'Flywheel' is no use to Kubus1 as he has an AUTO. Then with regard to 'Nitrous', "I wonder why the pros use it?" Quote Link to comment Share on other sites More sharing options...

But surley the principles are the same, less weight to spin on the flywheel, quicker it can rev, no...... Quote Link to comment Share on other sites More sharing options...
kubus1 Posted April 1, 2003 Author Share Posted April 1, 2003 Ashley, I found this on torque converters. http://www.converter.com/faqs.htm I have to admit, its all to technical. Maybe you can make out more of that. Cuba Quote Link to comment Share on other sites More sharing options...
Thorin Posted April 1, 2003 Share Posted April 1, 2003 A badly installed NOS system is a time bomb waiting to go off. A proper install should have at least a covered arming swith and also a throttle position sensor so that the NOS is ONLY activated at full throttle. Ideally you also want a progressive controller which you can use to delay the activation of NOS until a number of seconds after hitting full throttle and also introduce the NOS gradually over time etc. Things you would need to check before fitting NOS are mainly that your fuel pump is upto the job and also your coil packs. Obviously if you haven't already fitted an uprated clutch this would be a good idea too. Also, to get the best out of the system you may want to look at getting an ignition controller of some kind to retard ignition timing slightly.

Thorin Posted April 1, 2003 Share Posted April 1, 2003 I should also add that if you are using NOS and chucking in the extra fuel via an additional injector you do not want to be using any kind of traction control. Traction control kicks in, cuts injector pulses, NOS still continues to pump in extra fuel, engine runs very lean, BOOM. New engine please.

kubus1 Posted April 1, 2003 Author Share Posted April 1, 2003 Thorin, Great info. Anything else I should know?? Cuba Quote Link to comment Share on other sites More sharing options...
Thorin Posted April 1, 2003 Share Posted April 1, 2003 You should certainly be looking at no more than 75bhp jets with a single shot setup, but maybe as much as double that with a progressive system. Quote Link to comment Share on other sites More sharing options...
dude Posted April 1, 2003 Share Posted April 1, 2003 Got to agree with Thorin a PROPER nos install will be fine but everything engine wise must be up to scratch , you may well learn more on the us forums as its more widely used over there , read up about it and make your own mind up about the horror stories .

Alex Posted April 2, 2003 Share Posted April 2, 2003 Might be worth getting in some new conrods and a set of JE Pistons I'd love to see a NOS system in a Supra...a properly set up kit. I'm warming to the idea of it as you don't affect the normal drivability of the car and have a little extra kick if and when you need it. Must be more economical than running a bigger turbo!
