thinking of nos for drag racing..

[COOL][/COOL]considering getting this done as a few people have this, i know theres mixed views it wont get used all the time,

just thinking about abit more power, bought some drag wheels inc tyres to start.

car is not fully mapped got a few gremlins that afr will fix once its run'n better may get nos fitted while up at afr

jspec n/a - tt auto

eng spec

fully bpu'd

emu

650cc injectors

thanks

Nos is good, best to get it setup on the dyno with a good mapper though.

Not a bad idea for drag racing, though I have no experience on what effect it will have on the engine's internal. Though from what I understand Supra's stock internals can handle 700bhp, so a 100bhp of Nitrous on a BPU car shouldn't be too bad?

Is the Supra your everyday car? Or weekend and when the suns out?

Found some information which might be useful:

Internal combustion engine

Main article: Nitrous

In vehicle racing, nitrous oxide (often referred to as just "nitrous" or as NOS after the name of the brand Nitrous Oxide Systems) allows the engine to burn more fuel and air, resulting in a more powerful combustion. The gas itself is not flammable, but it delivers more oxygen than atmospheric air by breaking down at elevated temperatures.

Nitrous oxide is stored as a compressed liquid; the evaporation and expansion of liquid nitrous oxide in the intake manifold causes a large drop in intake charge temperature, resulting in a denser charge, further allowing more air/fuel mixture to enter the cylinder. Nitrous oxide is sometimes injected into (or prior to) the intake manifold, whereas other systems directly inject right before the cylinder (direct port injection) to increase power.

The technique was used during World War II by Luftwaffe aircraft with the GM-1 system to boost the power output of aircraft engines. Originally meant to provide the Luftwaffe standard aircraft with superior high-altitude performance, technological considerations limited its use to extremely high altitudes. Accordingly, it was only used by specialized planes like high-altitude reconnaissance aircraft, high-speed bombers, and high-altitude interceptor aircraft.

One of the major problems of using nitrous oxide in a reciprocating engine is that it can produce enough power to damage or destroy the engine. Very large power increases are possible, and if the mechanical structure of the engine is not properly reinforced, the engine may be severely damaged or destroyed during this kind of operation. It is very important with nitrous oxide augmentation of internal combustion engines to maintain proper operating temperatures and fuel levels to prevent "preignition", or "detonation" (sometimes referred to as "knocking" or "pinging"). Most problems that are associated with nitrous do not come from mechanical failure due to the power increases. Since nitrous allows a much denser charge into the cylinder it dramatically increases cylinder pressures. The increased pressure results in heat, and heat will cause many problems from melting the piston, valves or warping the head/cracking or predetonation

Drag racing with full BPU and NOS on the stock auto box will see the box break very quickly so be ready to change that and often

gazb uses it on his car drop him a pm!

Very good point Dean!

Few members running 500bhp singles on stock auto's such as Lui, a bpu with the odd 100shot for drag racing should be ok, if it was to fail auto boxs can be picked up pretty cheap, people give them away these days.

some good points so far all good apart from auto box..

will be setup on dyno for best results i think jon from afr got nos so can chat with him see which kit etc..

car is used for wk ends etc...

and who knows may even catch up with jamiep ???????

We try to keep 2 boxes at all times, these are FOC we just charge fitting, 5 or 6 meetings a year and say 10 runs per meet should not effect the box too much.

sounding even better so far, but i managed 20 30 runs maybe have to calm it down

I ran a big single on a stock autobox without any problems at all.

I will only be running an intercooler spray on my current build for now and see how we go. As I'm hoping the stock engine WILL last me a couple of years so I can save up for a 3.4 stroker.

Just out of curiosity does anyone know what power increase I matmy find with an intercooler spray. As on colder days turbo cars perform much much better.

No NOS on my car so can't help

For me there's lots of other things to spend money on to improve times other than more power
