really...

 

I spent less about $1200 on my set up and I pretty much have everything except maybe a lean cut-off switch.

I personally wouldn't go with a 3.3 FD. Spraying a couple hundred RPM sooner isn't going to help the launch all that much and will hurt other aspects of the car. Nitrous guys are N/A most of the time. With the 3.3 you may even save a bit of gas daily driving, but it'll be sluggish. A better suggestion would be to raise the rev limiter in addition to getting taller tires. FYI, the DE non-rev up 4th gear maxes out at 111mph so with taller tires and a higher rev limit should help those with large nitrous shots stay in 4th.

Just wanted to add that if the jet sizes don't change, the amount being sprayed can't change. The benefit in doing the above is that there's less delay between the solenoids opening and the nitrous/fuel mixture going into the cylinders.

As far as putting the nozzle after the TB, many manufacturers recommend that you do it before the TB and some even specify a distance. The only thing that putting the nozzle after the TB helps with is the fact that less nitrous/fuel mixture hits the plenum/tubing walls, allowing more of the mixture to go into the cylinders (hence "bigger shot" he's referring to).

One problem with this on the DE cars is the fact that the TB is situated right at the bend/neck of the plenum. My concern is that if you spray into that bend, the mixture will hit the inner walls anyway and even if you change the angle to avoid spraying into the bend, you're aiming more into the passenger bank. Remember, the nitrous pressure is ~1000psi so the exit velocity from the fogger will be pretty high.

 

Would it help to install the nozzles after the TB in an HR? If you are getting a "bigger" shot by doing this why not install it the conventional way and up the NOS? at the end of the day 115 is 115.

 

Honestly, I don't know. I would think that the nitrous/fuel mixture needs some distance to properly mix with the incoming air from the intakes so having the nozzle closer to the cylinders may not provide enough distance/time for it to mix properly. Too much distance (or wrong angle), though, will mean more chance of the fuel/nitrous mixture hitting the inner walls of the intake tube, TB, and plenum.

Instead of asking what if this what if that, why not just do what the manufacturers recommend? After all, they're the experts, not us.

 

on a Dyno Dynamics dyno, yes. Not at all impossible, just going to take some work.

 

a supercharged Z will make 420whp pretty easily with the right combo's and no it really didnt take much
