Since RWHP is made from torque and torque is made from pressure in the cylinder, comparing RWHP numbers should be a good indication. At 10lbs you will see approx. 500wrhp, with a 200 shot you will see about the same, so it should be pretty close.

Boost from what? There are different kinds of boost with their own unique powerbands... Not all 500 rwhp boosted LS1's can match the area under the curve a healthy breathing NA/Spray 500 rwhp LS1 can put out.

And turbos are a one time cost. N20, do you want to pay $80-90 each time to refills the bottle or hope you have enough left if you want to race someone??

If you pay $8 to $9 a pound to fill your bottle, I have some beachfront property in New Orleans to sell you.

From what I have seen Nitrous usually give the best curve in the area between 3000-5500 RPM compared to a Turbo or SC, but its TQ curve also drop alooooot faster after peak. Turbos and SC's usually hold its powerband much better than Nitrous setups while some of them match the Nitrous in the area between 3000-5500 RPM.

Another advantage i see from running a FI application over a Nitrous is how much can you run without breaking a thing. For example running a 200 shot on a stock bottom end is not going to last long as long as gaining 200rwhp+ from a FI application. FI is easier on the internals than Nitrous because of the way the power comes in unless you are running some kind of a progressive controller which would take away the Nitrous advantage in the 3000-5500 RPM area.

After saying all this.... I would personally do Both especially if you are running a centri SC setup.

They are nice, but hard to find. Also I really think a Maxed out D-1SC + 100 shot would eat up an incon Twin Turbo kit giving everything else the same.

Guess we'll find out... Fully built engine, meth injection, intercooled incon's, direct port nitrous with stand alone fuel system... Not really sure what you mean by " eat up" but let's be realistic. incons on here are making over 700 hp with nothing else.

I thought you were saying Incon Twin Turbo alone VS D-1SC and 100 shot.... If you are going to run Incon and NOS then it could go either way.

What i meant by eat up is that it will make more power everywhere in the powerband that if we are comparing Incon Twin Turbos "alone" VS D-1SC and 100 shot.

Are you using the stock Incon Twin Turbos?
