I have had my bike on the dyno to verify I am running a safe air/fuel with all the new parts. efir-13, fast fi, and .036 jet
All that netted me 200 RWHP so I took a carburetor jet drill bit and honed the jet out to a .038. Netted me some more with air/fuel still at 10.0:1. So after getting up to a .043 jetting and making 220 RWHP / 140 RWTQ blazing an ultra soft shinko I decided that was enough power to make me happy. Air/fuel still 10.0:1 until the upper RPMs where it curled up to 11.0:1. I am just curious to what a .043 jet is even equivelant to. With some better clutch springs I will maybe increase the jetting to a .045. But for now it runs pretty darn strong. All the dyno pulls were at 950 psi bottle pressure. I have since turned it down using a bottle warmer and running at 900 psi. Havent lost any races with this setup so I have not been urged to increase anything.
Thanks!

on your bike, 20 more than an .036.
How much HP does your bike make on motor?
If you made 200 with a 36, you are probably only making about 155 on motor.
A 42 jet is usually good for about 65 HP. If you use a spray bar, you usually get another 5 HP or so.

Oh I know this... I am just trying to see what a .043 jet was equivelant to since a .028=30 hp & .036=60 hp. My bike makes 165 RWHP so I understand it is only a 55 hp gain for me. This .043 jet size is just all curiousity to me on what hp it is if I wasnt drenching the engine with fuel and pulling so much timing.

Rough numbers:
28 30HP
30 34HP
32 38HP
34 40HP
36 45HP
38 50HP
40 55HP
42 65HP
Of you drill them, you will usually get slightly less as the orifice is sharper adn not a radius on the lead in. A spray bar will allow the nitrous to atomize a little better and make slightly more HP.

Thanks. That makes sense. I have considered the spray bar, just haven't convinced myself yet since the bike is running so well.

Contact Chuck wilburn for a spray bar...maybe he'll throw in a new jet or two for ya.

I may contact him. He is who I purchased my nitrous kit from. Plus its great how he is so easy to get in contact with.

don't think your a/f is right doogs

i am saying it doesnt look like 14.1 on the graph unless i went retarded looking at it(entirely possible) :D
-
Thats just what Ryan told me. Maybe it was 12 hell I don't know. it runs perfect so I don't care :P
-
:D
-
a 42 jet is good for 60 and a 44 is good for 65 (actually 64 on my bike)
-
and if it helps ya any. just took the bottle off from last friday. .o42 jet spraying @ 7.5 seconds per run. full 6lbs15oz's pulled off at 4lbs 5.9oz's. first run was 152.69, 3 more at 151.5 and last was 153.6 (spun bad). no syphon, mounted upside down in arm.

So 5 passes with a .042 jet and you used 2lbs 9.1oz's of nitrous

uh huh. i'm gonna log my usage and how mph drops off more this year. kind of a prehistoric datalogger :lol:

ANYONE KNOW IF WHEN PC3USB AND HUB IS CONNECTED TO LAPTOP AND SWITCH IS CHANGED FROM MAP 1 TO MAP 2 ARE THE NUMBERS IN THE MAP SUPPOSED TO CHANGE ON THE SCREEN OR NOT

No clue Bud :?:
Call or e-mail dyno jet I sure they can tell you.

HOW DO YOU KNOW YOURS IS SWITCHING BETWEEN MAPS THERES GOT TO BE A WAY TO TELL IF THE 100% CELLS HAVE CHANGED OR NOT

Schnitz had the Nos map loaded when I left from the dyno so I just left that one in there. No change in the map until 7k so it just get rich on the street when I get on it. Haven't taken the time to play with the lcd yet for switching
-
I BELEIVE I FIGURED IT OUT DOOGIE THANKS ANYWAY
-
Hey War,
I finally played with the LCD tonight. it doesn't really tell you what map is in there. I did hook up the laptop to the pc and it did switch them so I know it works but I need to figure out why it isn't telling me which map is loaded :?:
-
I KNOW VERY LITTLE IF ANYTHING ABOUT THE LCD BUT ALL IT IS IS A SMALLER LAPTOP FOR YOUR BIKE GET OUT THE INSTRUCTIONS IM SURE ITS IN THERE
-
hub should say map one and map two on the left side of the screen and the numbers should change long as you have two maps loaded but not sure on the lcd though

HE HAS THE LCD NOT THE HUB I HAVE THE HUB I SAW THE NUMBER CHANGE FROM 1 TO 2 ON THE RIGHT SIDE BUT WHAT I WANTED TO KNOW IS DO THE CHANGED CELLS CHANGE ON THE SCREEN WHEN YOU SWITCH MAPS MINE DIDNT BUT THE MAPS WERE SWITCHING OK I TOOK IT FOR A TEST RIDE YESTERDAY AND WENT FULL THROTTLE AND IT BOGGED AT 100% BUT NOT WHEN I SWITCHED BACK TO THE REGULAR TRACK MAP DOES ANYONE KNOW IF THE FI LIGHT IS SUPPOSED TO FLASH MINE DID WHEN IT WENT RICH ( NO NITROUS JUST TESTING ).

Are you spraying this much with stock valve springs?

My fi light comes on if I dont spray using the NOS map also. I am told that it is normal because the a/f mixture is so fat. It never comes on when I spary or if I use the all motor map. Only if run the NOS map and dont spray. Hopes this helps. One day I'm gonna pull the code to see what it is. I bet its gonna be an injector or a coil code.
