it made 520 543 on blower only and yea its been on 2 dynos and it made with in 10 hp of each other.

So it picked up 180. Depending who you ask it's either a 200-210(bhp)shot or a 180 shot (whp). When most people say "100 shot" it's to the motor. The only real way to know is by the pull size. I would guess a .068?

well going there haha but it does make 700 so we will leave it at that. car does fly like that and seem to have no issues for now and if it would later just have to fix it. the only reason i even done it was because when i first got my car i was told there was no way to make it run with a whipple cobra and that it never would so i just started reserching it about the spray and this is what i ended up with. seems to work well if i can get some more traction. if you have any input on that it would b greatly appericated.

also from what ive read that spray on a charger makes a little more than on a na motor mabye thats whats going on there.

yes the air in denser and you make more boost....but its not like you make more boost with more nitrous. a smaller shot in my experiences shows more gain and then they tend to flatten out as you go up. Your not making 180 to the tire on a "150 pill". Thats all. Just wouldnt want someone else to try a 150 and not get similar results.

You will not have a problem with running nitrous thru the blower unless you have a poor tune for it.
Make sure you use good octane in the tank 93 or better on that 75 shot and remove at least 2 degrees of timing in the tune.

The one issue you will run into is that the fuel rail you tap into for the wet side of the nitrous will start to run that rail lean on activation only.
It's a momentary spike that some guys are OK with... I'm not okay with that so I run a stand alone fuel cell on my wet system.
This way I don't have to run a tune separate for the nitrous and worry about the lean spike.
Plus I can run a larger shot with the cell. I run 110 octane in the cell, 93 octane pump in the tank, and a 150 shot of spray with no problems on 14 PSI boost. Do yur homework and you'll be OK.

As venom said i also had a problem with that fuel rail i would get a frps code from the activation,i went through 3 sensors before i figured this out.Just incase i thought i would pass on my experience.Sucks to waste money replacing sensors that are good.

this is my plan also.. going to get a tune anyway, so might as well get a nitrous tune.. what do you think is a good starting point for deep 10's?

depends where you are on blower only....in my experience I got these reductions in my ET

50 shot = .3

75 shot = .4

100 shot = .5

this is on a 10 sec car....a slower car will see a bit more

Hey I know this is pretty late but has anyone ever ran E85 with blower and nitrous ? Can you even do that?
