i was very happy with this run, this is my first run in a 4 cylinder front wheel drive car on a dragstrip.

my bottle pressure was at 875 psi. VERY LOW and NOT ENOUGH PRESSURE TO GET THE TRUE HP FROM THE NITROUS SYSTEM... i have not yet installed my bottle heater.... sad.gif

the car was weighed..

without me in it. 2680 (no spare tire)
with me in it 2850 (no spare tire)

well, thats all folks.

i can go 14's with 950 psi in the bottle, i'm 100% positive i can do it.

also, my car is 100% bone stock besides the nitrous system.

stock muffler and everything. AUTOMATIC smile.gif

HORSEPOWER CALCULATOR SAYS...
Your trapspeed was 93.83 miles per hour
and your vehicle weight was 2850 pounds.

You are making 187 hp at the wheels.

that is 10% less than my engine power of 210 HP with nitrous.
so my automatic is sucking up 10% of my power to move the car... not bad for an automatic !


at the track... i raced a GS-T eclipse with 16 psi of boost, intake and exhaust, upgraded computer system.. .. he also had the heads up computer similar to that of "fast and furious movie"....

i beat him by a full second.

his 1/4 mile time was 16.462 @ 88.08 mph. !! HA !!!!

Have you ever went through and calibrated your nitrous system. If you haven't done it it, its a good idea.

FordFasteRR

hehehe

and how would i go about "calibrating" my nitrous system ? hehee

i know i'm running slightly rich.
i dont have an air/fuel guage.. but i dont need one. i've already calculated my fuel flow requirements and my MSD pump triples it. why would i worry ? besides, if its not running right, i'll melt a hole in a piston in two seconds anyway.

HRD_Tiburon

What I do is is weight the bottle first. The correct Nitrous/Fuel Ratio is about 8.7:1. Eight pounds of nitrous to one pound of fuel. What you have to do is unplug the fuel solenoid anf spray the bottle for 30sec. Weight the bottle again and record the weight. Then unplug the Nitrous solenoid and run the fuel for 30sec. Record the weight of the total fuel sprayed.
If you have flown to much fuel adjust jetting to a smaller jet or you can adjust fuel pressure to drop the volume. If to little of fuel then increase fuel pressure or jet. You can tweak the tuning by just adjusting your pressure.
Make sure your bottle is at operating pressure around 900-950psi, just turn your bottle heater on to tune the pressure.

i've read about this method before.

i go by another method.... its not as accurate as yours may appear to be...
but i just follow the recommended jetting and i run a fuel system that is way more powerfull than what i need.. mine is capable of 500 hp... but i'm only pushing it to 210.

the only way to keep your engine from blowing up is to run a strong fuel system, and good spark plugs and good gasoline.

What's up with that reaction time?

FordFasteRR

that was my first time racing an automatic 4 cylinder car at the track.

i still dont have the tree down either sad.gif


its ok. i now have my bottle heater in my hand... it'll be installed soon, and i will be in the 14's with that.


can someone point me in the right direction for the headers that produce the most torque on a beta engine please ?

will it be the 4-2-1 ? or 4-1 ?

i do not want top end power, i want more torque.

Auto beta engine cars run the quarter in about 17 and a half seconds, and have about 105HP to the wheels. Are you running a 100Shot of Nitrous?

Bat Lord

that goes to show you how inaccurate HP CALCULATORS are... you should be at no more than 174-176HP at the wheels, if you're pushing with that 70shot of nos... sorry bro, and I also believe teh elantra is a little heavier, which really doesn't do much on a dyno but on the track you will feel it, so it could even be less... there's a place up in Broward that does dynos, for like 70 bux for 3 runs, if you want prove of what you're really running... other than that congrats on your time, but once again, I say becareful man... that tranny won't hold for long pushing it like that

it doesnt make much sense to me that a 140 hp beta would loose 35 hp through the transmission dude...

sorry... but i used the ultra powerfull "windows calculator" to determine the drivetrain losses of a beta automatic..

lets pretend i loose only 10% power that leaves me with 126 Wheel Horsepower.
Lets go a step further, and pretend i loose 15% power... that leaves me with 119 wheel horsepower.

i would say that my numbers are accurate, and yours are not. besides, i will scan the time slip and show it to you.

my jetting combination is 41/26 go online and find out how much power that jetting adds using an efi fuel system. (the jetting would be totally different if it was for a cabuerated car with a low pressure fuel system)...

so i think that 187 Wheel Horsepower is just about dead on with a 70 shot.

if you add 10% to 187 you get 205.7 HP. if you add 15% you get 215.5 HP. so i would say i am just about right in the middle of that figure *engine horsepower.

93.83 mph shows the horsepower is there.


have fun yall ! laterz.
