supra dan Posted April 13, 2003 Share Posted April 13, 2003 had my first taste of 1/4 mile racing yesterday, now i've got the bug i want to go faster! i was going to get nos, but maybe traction control would be better as i was getting too much wheelspin off the line. anyone any advice?

qaisar Posted April 13, 2003 Share Posted April 13, 2003 have you got an auto or manual, cos the launch control doesnt work with autos Link to comment Share on other sites More sharing options...

supra dan Posted April 13, 2003 Author Share Posted April 13, 2003 manual box, where do you get drag radials?how much difference do they make? Link to comment Share on other sites More sharing options...
dude Posted April 13, 2003 Share Posted April 13, 2003 Dan BF Goodrich, they make a lot of difference to your elapsed time but not your top speed . John:flame Dev Link to comment Share on other sites More sharing options...
supra dan Posted April 13, 2003 Author Share Posted April 13, 2003 are they expensive? maybe go for tyres and nos.mmmmmmmmmmmmmmm Link to comment Share on other sites More sharing options...
qaisar Posted April 13, 2003 Share Posted April 13, 2003 as u got a manual the rltc might help, the launch control minimizes wheels spin or something, if im correct you can nail the accelarator and drop the clutch and the rltc sorts it all out, maybe an exageration but along those lines Link to comment Share on other sites More sharing options...

Syed Shah Posted April 14, 2003 Share Posted April 14, 2003 Thorin, are you sure? I would have thought that as long as all injectors were cu, N02 would pass through safely? Alternatively, if that is the case, you could alway use the N02 shot further down the track when the car has traction. I reckon the drag radials would be the most cost-efficient mod, for drag use only. The RLTC and N02 enhance the road performance as well as the track.

Thorin Posted April 14, 2003 Share Posted April 14, 2003 Originally posted by Syed Shah Thorin, are you sure? I would have thought that as long as all injectors were cu, N02 would pass through safely? But you have NOS AND extra Fuel being added with a NOS install. Most NOS installs supply their own fuel though an additional injector in the intake pipe. The trac control would cut all the injectors but the NOS system will still pump fuel in. Bang.

Syed Shah Posted April 14, 2003 Share Posted April 14, 2003 Which is why I said all injectors have to be cut, the RLTC has capacity to do this. So N02 and RLTC are fine as long as the RLTC controls the extra fuel? Obviously allowing just the N02 fuel in would make a very lean mix, and a very big bang Link to comment Share on other sites More sharing options...

Even so it would need to be able to acurately cut it at the same time as the normal injectors and I'm not sure I'd trust it. Link to comment Share on other sites More sharing options...

supra dan Posted April 14, 2003 Author Share Posted April 14, 2003 ok, drag radials, rltc, and six bottles of nos on a roof rack! sorted.seriously, thanks for the help Link to comment Share on other sites More sharing options...

Even so it would need to be able to acurately cut it at the same time as the normal injectors and I'm not sure I'd trust it. I don't think it is designed to do that. Alternatively you could get the box from RaceLogic that makes the TC control the spark instead of the fuel (for cars without MPFI), that way you would not ignite the mixture but it would dump loads of fuel and NOS out the back, which I'm sure would get ignited by something.:flame Dev Link to comment Share on other sites More sharing options...

Nathan Posted April 15, 2003 Share Posted April 15, 2003 Originally posted by Thorin I don't know if the RLTC has the ability to control the additional injector, does it No in the normal way it doesn't, but it may be possible. The problem is that most NOS and fuel jets are nothing more than a small tube. Their flow is mechanically controlled via solonoids. The injectors have no electrical signal whatsoever. The only way around it would be to stop the solonoids seeing a power signal. Theres absolutley no way I'd want to see NOS and fuel being injected on a car whilst RLTC is activated. Could be devastating. A customer of ours fiddled with an install we done and manged to activate it whilst the engine wasn't running. He had a NOS ignition inside the inlet manifold and promptly blew every single boost and vacuum pipes to pieces. He was v. lucky he didn't blow the manifold apart or bend the throttle plate like a banana. You may be able, if you set the NOS trigger point to be at a high boost level, to get away with it. Most turbo cars, whilst running an activated RLTC will not make over 1 bar. If your NOS was set at say 1.2 you might be alright. But you might not. Look into it carefully, and plan it out. Just don't let some divvy tuner just slap it all on there. Regards, Nathan TDI PLC Link to comment Share on other sites More sharing options...
Thorin Posted April 15, 2003 Share Posted April 15, 2003 Gotta agree with you there Nathan. As I've said, I don't think I'd trust it. Have considered NOS at some point down the line but not RLTC. I wouldn't mind a demonstration of both at some point though I've yet to ride in a car that had either. Link to comment Share on other sites More sharing options...
fastisnice Posted April 15, 2003 Share Posted April 15, 2003 WHats your BHP by the way and whats your 1/4 mile time.I would go for NOS Set it to go up to 1 bar to get rid off turbo lag. There is a rumour of per/75bhp of NOS you get 0.5 - 0.6 of a sec better timing on your 1/4 mile which can do big difference... Link to comment Share on other sites More sharing options...
supra dan Posted April 22, 2003 Author Share Posted April 22, 2003 had the following reply from racelogic; " the tc is safe to use if adding no more than about 150bhp. any more and i would not reccomend using rltc". as i only want about 50-75bhp looks like i will be ok.

Adam W Posted April 22, 2003 Share Posted April 22, 2003 I'm no expert but that sounds like a bollocks answer to me. Something like that either works or it doesn't, no matter how much nitrous you're using! Link to comment Share on other sites More sharing options...
