also remember that if you're spraying a "75 shot" you're only really getting ~60-65hp to the wheels... drivetrain losses still apply.

 

no, they don't. If a .46 nitrous jet and .26 fuel jet is being run it puts down a certain amount of wheel power, again, wheel, not crank. It matters what company it is, they all run specific jet sizes to their own preference.

 

They call it a 75 shot based on the jet sizes. It'll generally add 75 horsepower to a typical street car. What they don't tell you is that a high compression motor that flows really well (like the F20/F22) generally gets more horsepower than what you would expect, and a motor that sucks will get less horsepower than the "75 shot" would make you expect.

I've seen built 11:1 engines get 70 whp from a "50 shot", and I've seen a tired old 302 get 60 whp from a "100 shot".

 

Theres just as many pros and cons about each setup. When it all boils down, learn to drive your car b4 u mod it. My apologies if i offend you but I would be embarrased to say my turbo'd s2000 only runs 13s.

Q) How does bottle pressure affect my performance?
A) Achieving optimum performance from a nitrous system relies on both the fuel and nitrous being delivered through the nitrous system in such a way as to maintain a constant mixture ratio and this is best achieved by trying to maintain the delivery pressures of both at constant levels. The jet sizes provided with the nitrous system will only produce optimum results if both fuel and nitrous is delivered at the pressures the jets are intended to work at.
Unfortunately nitrous bottle pressure depends on the ambient temperature and the consumption rate that the nitrous is used at. A low ambient temperature will result in a low bottle pressure and high nitrous consumption (larger jet/s) will cause the bottle pressure to fall more rapidly than low consumption (smaller jets). With the above in mind it is essential to hold the bottle as close to the right ambient temperature as possible, so that the jet/s deliver the correct amount of nitrous from initiation to end of use. Adding a bottle heater is a good method of minimising the drop in bottle pressure and pulsing the solenoids helps to maintain a more constant level, while also providing a more controlled power delivery.

 

Let's see my car runs in the 13's, I beat a new GTO in the 1/4 mile and lost to a Shelby gt500 by 1/2 car but ran a better time. The track I run on is a bit rough. I am not embarrased by that.

Go do what you want had have fun with it. That NOS set up looks cool and fun place to start. Meth is not a good option for your car at this point.

 

curious what your trap speed was. i am going back to track late may, hoping for some serious improvement over my times. last time at track i couldnt floor it until third gear

revenge are you dumping or feathering?
o and get my N2O on tues!!!
thanks directport for the info. its tough finding plugs around town

 

I order my denso IK24's offline. I dont think a lot of auto part stores sells them direct.

 

i managed to source some NGK Iridiums that my buddy at BVP had for his s2000 N2O build so imma use those. Get my whole kit tues. install on sunday and i'll post up a DIY if i can for all those guys wanting nitrous builds
