Unless you are very experience with nitrous and riding a nitrous bike, I would stay away from such a big shot.
Put a 75 shot on it and learn to ride the bike without nitrous, then start adding in the nitrous.

The key to nitrous is getting a handle on teh bike and a starting percentage. Keep increasing the initial hit, or decreasing the delay from the initiation until the chassis can't take any more. After that, then you can start increasing the amount of power you spray.

No sense in wearing out the motor early by spraying a huge amount out the back door only to have crap for 330's.

150HP on top os a 1441 is no joke. That's big boy power. If you aren't used to it, both riding and tuning, step back at first.

If you are going to dragrace alot and your goal is to go quicker, put an engine driven lockup in it and run it on motor until you get it to the mid-high 8's consistently depending on your weight. Then start with about a 75 shot, figure out how much starting percentage you can spray, and hen start throwing more nitrous to it.

There is an issue with big spray on a dry setup on a stock ECU in that it is difficult to tune properly for a progressive shot, making it have enough fuel for alot of spray and not be so rich that it is a dog at the hit. There are ways to do it, just not trivial.

What controller, what brand solenoid(s) and what size solenoid(s) are you using?

Havent really decided what controller to use , Ive got a big shot nos solenoid , and am definetely going lock-up probably mtc. i appreciate your feed back and will take your advice on starting with a 75 shot .. i want to do biker bash in september and be as consistent as possible . any good recs on a controller would be appreciated.also i would like a good drag shock and will be using a power 1 or drag hook up tire.. which ever holds best.. definetely want to be maxed out by beggining of august..im running 9.20 on my 2012 stock motor very small dry shot(has 1200miles) stock exhaust with some hot boddies slip-ons and a mild airbox and of course tuning.so i hope with this 1441 high compression motor and all the other shit im spending money on im in the mid 8's..lol

I like the Daytona NC2 controller.
If you don;t have a clutch now and you are dragracing the bike, save your money and get an engine driven lockup. Not sure if that is what you meant by your post. They are very expensive, but cheaper in the long run considering you will likely progress much faster and not have to have so much seat time trying to figure out the clutch.

How long is this bike and how much do you weigh?

If the track isn;t prepped well, you will likely have a hard time with a street tire at anything over 66 or so inches with big power.

I should be done with my head this week so will be building motor this weekend. I am 165 and bike is 66' .. I will no doubt look into engine driven lock up. rite now on this bike I have stock clutch with cushion I know that's not going to cut it and am also clear that my clutch set up will be pivotal  in my quest to reach that next level..

Thats alot of nitrous :eek:...Going from a stock motor to 150 on a 1441. :shock: I would do a 50 on a 1441. That's what I had on my little crazy 8's bike. That thing went 8.39 at rockingham and Im 230 lbs. With that compression and a 50 you will fly at 165 lbs.

    Kool, thanks for the advice.. I'll probably go 75 to start . I know its alot but I think im ready and eventually go bigger progressive and see what happens...lol... i'll be very happy with low 8's (for now) .. also I have these huge injectors I was hoping someone had some advice on that.. 850cc injectors is what i'm going to run first for break ini'm going to run stock but I will flash for the big boys soon .. my goal is be ready for mancup in braedenton ..I think I have time to mess with it .. I got injured on the job so i'm a little delayed on the build but i'm hoping to finish this weekend.. need advice on degreeing in my cams .. have webs was thinking 104/106

p.s. would like to go progressive dry

Using a Gen 1 ECU and a progressive 150 dry shot is very tricky.  Even if you start the progressive ramp at 50%, the AFR will swing down so rich that you get engine miss when the nitrous is pulsing off.  It ain't smooth at all.

S2000 injectors work great for that combo. That's what I had and they where not over rich at all. Never maxed out either. I didnt have big cams either. ( .395 and .378 lees performance head)

John has a boat load of info he can guide you in the right direction. He taught me alot.

Yeah thats what i was thinking also. A motec will do it though. But thats big bucks. Easier and cheaper to go wet. Get a good nitrous fuel pump  witha good controller and your set. Changing jets is easy.
