    The tech forums have way less BS in them and a WIDE range of opinions. Some really sharp racers hang there. Like Vince says, good people and most are hardcore racers.
    don't forget the thong thread, the redhead thread

    I was down in the nitrous section at the bullet earlier, and I guess a lot of guys planing on spraying are opening there quench up to .065 or even bigger. I'm not saying you'd want to or need to with a 200 shot, I just thought it was interesting.

    200 shot of nos is only an added 25 hp per cylinder not much of a problem BUT in larger amount's touchey i agree with hotby's post #17 and impatient's post #21
    i have run well over 600 hp nos with alky enrichment systems BUT every thing has to
    spot on . just one weak or wrong part combo and thing's can get terribley expensive . ( once had a no2 sol. hang open at the end of the run and when i let off the gas the top of my 2-4 manifold and carb's went for ther own ride . NOTE blower restraint straps on a nos motor just might keep the manifold top from comming you'r way . learned this the hard way , throttel cable brought it my way .

    Dont think i ever said my goal was to hit 100, would be cool though. I've set out to make this boat as fast as possible problem right now is that saftey is really a big concern of mine. I have kids and a new one on the way so i need to be as safe as possible. Right now my boats all outta wack and i need to get it dialed in. One big concern right now is that i've only had it out once and the bottom infront of the intake where the intake used to be is cracking. jack's not seen a boat do that before and told me to keep a close eye on it. A new hull has always been in my future, just a matter of when.

    On a different hull ?? Why ? I thought your goal was hitting a 100mph ? You have spent alot of time and money on this hull, and a 150-200 shot is whats going to really make it run. Believe me, I went through it with my Miller. I was making over 800hp, w/ every bell and whistle on my MPD built pump, 540lb. hull, blueprinted bottom, yada, yada ..... and only got 102mph on the motor. On the bottle, the thing was a handful. It was only 5-6 mph faster, but it was waaaay quicker. Not saying your boat won't run well, but any tunnel, CP, or flat w/ your same power will walk you everytime. You put a unit on your boat, and you will have way more fun and win way more races. Then when your done with all the slow boats in Parker....come to the other side

Would be cool to see some before/after dyno sheets to see what happens to the curve.
    i don't have any dyno sheets, but i was sprayin 450hp in 2stages in my gullwing and when i'd bring in the 2nd stage , rpms would go over peak and i would have to let outta it by 1/2 track to let the motor settle back to peak, sob would start pulling harder again after that i knew my cam was peaking just above 7k so i impellored it till i could run the 450hp shot and stay near that peak, boat did sooooo much better that way you can do the same if you end up above peak on the nitrous level you wanna run, just stick a bigger impellor in till wot is at peak on cam when on the juice. makes for a meaner holeshot anyways

    hope this helps.no expert but i have learned that nos is not just fun as hell,but can be very safe if you pay attention.good luck
    Probably why he told me 6200-6300 on the bottle, think i was telling him at the time i was thinking 150 shot.
