Shot MAX in Celica

[komar]

What determines the shot maximum for a car? Why can the Celica GT and GT-S only handle a 75 shot max? If you have more fuel can you shoot a higher shot; 100 shot with more fuel (s-afc) would this work? Why can the LS1 (TransAM, and Camero) shoot a 150 shot? How much extra stress does a 75 shot add to the drive train, on a GT-S? I just want to know if anyone has thought about or tried to run higher than a 75 shot on a GT-S. If a person were to get the forged pistons would this make a difference?

i think it has somthin to do with the pressure blow the head up or somthin.. or u might just make your floor board fly offhehe j/p

[MattTheTerror]

The reason is due to the internals of the engine. If you had forged pistons, connecting rods and posibly crankshaft, better head gasket (current one is esspestis) and fuel managment you could push alot more. If you dont think 75 is enough for you get yourself a bottle heater. Without you keep bottle pressure around 650 which doesnt seam to be much.. Now with a bottle heater if you keep it near 850-900 It will be alot diferent. But like how it has been stated tons of times, if you want the F&TF type thing, get a turbo or supercharger. With forced induction the Nitrous is basically multiplyed due to it cooling the intake charge so much.

thanks Matt, i was just wondering. Maybe my post was overzealous.(I like the movie F&F, some parts were just too unreal but other than that...) I just want to know what sets the limits on a celica, or ant car for that matter. I am not looking to run over a 50shot right now just wondering about the limits.

thanks

So, you think it would be ok to run more than a 75 shot if you keep the bottle pressure up?

[kuruptgt]

you shouldn't use the nitrous with any shot if the bottle pressure isn't at leat 900-1050 or somthin like that thats optimal bottle pressure any less the nitrous will spit and cough instead of spraying. yes i know this cause i had nitrous and spent countless hrs on the phone with techs from NOS,NX ,zex,and nitrous works all had the same response.

I was implying that if your 25-75 shot isnt fealing lively enough for you then get a bottle heater. When you keep the pressure it up it makes worlds of diference. Ask Larryd He knows about this and he is in a celica so he can tell you the diference it makes.

[larryd]

well its more like if your running a 50 shot and you dont have the bottle pressure right then you might only be getting enough pressure for a 30 shot :).. first thing to do is make sure the pressure is ok, I was planning on running a 75 shot at the track eventually but I didnt get the chance.. though I wouldnt keep it in there all the time.. Id only use it like 3-4x a night at the track once a week if that often.. I was forwarned by 2 companies not to go over 50 on the Celica :)

[BoyRacer]

i wouldnt go over that (50)....... its a no matter which damn way you look at it the car is still a toyota. hehe.

Larry

With different internals; Pistons, con rods, shot pin the crank. keeping the CR 11.5:1. A 75 or 100 shot is possible???

Kareem

[larryd]

id say with forged internals that 100shot should be possible.. but Im not an engineer so I cant be positive though :)

[yewknowit]

Just curious, how long does it take for the pressure in your bottle to rise (before and in between runs) on the average?

[Bryan H]

this is WHY you can't do that
one, the ls1's have a larged displacement
thats a given
bigger engines. handle more nitrous

a 50 shot on a celica is roughly the equivelant of a 100 shot on a 5.0 mustang

smaller motors can not handle that much nitrous
rods. pistons. basic combustion chamber pressures would be to extreme on stock internals to do it.

if you want a 150 shot, go buy a v8

the rules of physic's can not be broken. remember that
you can bend them. but only if you know how to get away with it {IE my celica}

[yewknowit]

What if you added a fuel pump to increase the pressure of fuel (spray more fuel with the NOS), would it then be safer to spray more NOS?

Hi. this is reality. it is not kicking you in the junk

you are, lack of better words, cramming a crap load of oxygen into the cylinder. chamber pressure is going to go nuts no matter what fuel is set at. cylinder pressure is what you need to watch. not fuel so much {just for detonation}

50 compared to a 150 shot would equal three times the cylinder pressure
it would run, but not for that long.

if you wanna find out, you can get a 2zz motor for toysport for about 3500-5500.

re-read what i typed.

i'm ran 75 shot direct port a couple of times and the motor is still holding. i just run some 104 octane gas and gap the plugs at 30. i wouldn't recomend it for every day. i run a 60 shot for my street driving/racing.

[komar]

kool thanks for all the replys guys

Kareem

[larryd]

besides.. in all honest with a 50 shot on the celica with a good driver its quite possibly a 12 second car.. what more do you really want.. 50 shot with good bottle pressure will keep the car spinning through 2nd gear..

[phillytec]

What kit is best for our cars and how much does it cost??

[larryd]

god if I had a dollar for how many times thats been asked already :).. search and yee shall receive thy info :)

[komar]

CAR IS UNDERCONSTRUCTION, PISTONS, CRANK, RODS, FLYWHEEL, CLUTCH...GOING FOR A 12 SECOND OR LOWER DAILY DRIVER. 75 SHOT WILL BE USED 100 SHOT POSSIBLE, ACCORDING TO MY TECHNICIAN.

yur doin all that for a 75-100 shot. im gettin my NX kit prolly this week and i bought the 100 shot jets with intensions of usng it just on my stock motor.

[larryd]

haha.. be careful there man.. 100 shot on stock bottom end is no joke.. hope you dont blow your **** up..

[kuruptgt]

yea thats cause im hardcore http://www.imagestation.com/picture/sraid28/pf47175aaa3c580b4411cedb7f3dba335/fdf965ca.gif

[larryd]

being hardcore and stupid is a very fine line

[Iwannagofast]

Yeah I ordered my NX kit a few weeks back and dammit as soon as I get the kit in I am doin a 75 shot and if all seems good then I am doin to 100 shot.... John Said they have a new celica on a 125 stock right now

[larryd]

good luck guys..

[Slant]

I smell trouble...

[BoyRacer]

i feel dumber just reading some of the responses in this thread. good night to all and to all a goodnight. dont come crying when you blow your motor, and half your face off.

[komar]

WELL I AM DOING ALL THAT WORK TO HAVE A CAR THAT WILL LAST A WHILE...NOT 10 RUNS AT THE TRACK...BOOM!!

KAREEM

[kuruptgt]

half of my face blown off umm no my motor probably but who cares my excuse to get a new one. im gonna use some 116 race gas to hopefully stop detonation.

[Rizzo2kGTS]

so larry d you think 50 shot is safe for a gts with stock internals? surely there are hundreds of posts on this for me to search through but i had a late night last night and i'm really tired/lazy right now. your opinion is highly regarded...(im not too tired to kiss some ass) lol...

[larryd]

yes.. i think 50 shot on a GTS is fine.. i think these guys talking about 100 shot is nuts..

[kuruptgt]

yes we are http://www.imagestation.com/picture/sraid29/p5e24eb047283f103035b25e2c222a56d/fdef1c0b.gif

Komar who is doing the work for you?

[komar]

a shop in houston, called AutoPercision is doing the work. They have a bad ass Z8 with a blown motor in the shop right now, number one piston is no more it is all shavings and pieces. The parts are from monkeywrenchracing.com, the crank is being strengthened locally, the parts are on the way according to the shop just waiting on UPS ground cause the next day was like 2.95/ lb. I am also doing some minor head work, stiffer valve springs to help keep valves not float. Should be running in about two weeks.

in responce to larryd's comment "yes.. i think 50 shot on a GTS is fine.. i think these guys talking about 100 shot is nuts.." I am only running that at the track when I do. Rest of the time 50.
