Instant power! If my 260ci motor has troubles spooling this new s366 88ar turbo on the current converter I'm going to add a dry shot set up on a push button.

Your tune would have to be way lean to blow H/G with a 50/75 shot.
Spooling a turbo with nitrous is almost considered old school now. Before the better turbo/converter technology came along it was popular on these cars.

you will barely be able to feel a 50 shot ... 75 is more pronounced ... 125 will start to get your attention .. and a 200 will wreck parts quick ... even with a good tune ..
Combine it with E85 on a wet kit and you will be within reach of a LS ... at least for a few passes

Donnie Wang has extensive experience w/ this stuff. Maybe, he'll chime in.........
Before you start spraying your fuel has to compensate for EXTRA air you have just added. Better to be rich, than lean. Timing becomes a issue also. Most chips go aggressive on time, where as with NOS, you want drop the timing 1 to 3 degrees depending on the level. NOS is worth more on a 84-85 GN/T Type. A 50hp is worth almost 90hp. A 75hp is worth almost 120hp. Due to the heat a HA makes, NOS really cools down the charge from 300 degrees to around 130-140 going into the intake. You will also gain boost. I sprayed a bolt-on, 14 sec 85 T Type into the 12's on a 50hp. I had a Kenne Bell NOS chip for a HA. It remove speed limiter and lowered timing. I also had a hotwired Red Armstrong XP pump. I spent hours on the phone (Kevin/Mike Thermos) with NOS. I used a wet system with a WOT window switch. Off NOS, I run 14-15lbs off boost, on NOS 17-18. I had 60lbs of Fuel pressure at WOT. I was rich for a reason... NOT to blow head gaskets
. I actually had more on the table, but I stopped there. My tranny started slipping on slicks. I had been running BFG R1's. When I started running restall D5 and slicks, the tranny said "NO MAS" . Only mods to tranny beside convertor was Transgo Kit. As my daily driver, I took NOS off. My Buddy had 125hp NOS on his GN was running 11.97-12.10 and also started to have tranny issues. Bear in mind this was in the early 90's.
Thing have change, with the emergence of E85, I am looking to trying NOS again... ZEX and NX, both have EFI systems that have a box that reads the TPS sensor. This would be the only way I would go. If the TPS and bottle pressure not right, it will not fire NOS.

You will have to work slowly up on a solid combo. NOS is good on a turbo car. People are GREEDY when it come using it.. GREED equals headgaskets

What level car were you starting with ???
A 75 shot was good for 12.2x @ 111 on a almost stockish car ... same car on a 150 went 11.2's @ 117 ... on a 200 went I believe 124 but we changed to a dual stage off a throttle switch ... It didn't last long with the 200 dual stage
on another car that ran 11.7x @ 112 ish on motor .... with a 75 shot ran 11.3x @ 117 ... we did try it with a 125 .. but it was more than the car could hold on the street.
it felt quick but nothing like what the car with the 200 dual stage felt like.
I'm surprised the stock pistons took a hit that big.my stock motor cracked 3 pistons on a rich afr well into the 10s it lasted a while at that power level though.i left off the spray and ended the runs on it no window switch.easiest power the car ever made.

NOS is a "learned" medium, just as turbos are. My friend Lon has always been an NOS guy. He is the "Bison" of the NOS forums. His personal car is a 706 Fulton powered 69 Camaro with 4 stages. Something in the 3000 horsepower range.
I've never heard much on NOS with a turbo ( as a power adder. I have heard the spool use)...I always just figured we added boost. With the turbos on the market...why mess with it. I was watching the dyno tunes last year at Norwalk, and the 67 HPQ and others were adding 30-35 horse per pound of boost. 3-4lbs is your NOS shot.
The search for power always leaves a trail of broken parts, so just pick your poison...turbo, blower, NOS...to pick 2 of the 3....OUCH!!!!

On a 200 it didn't take it for long .... wrist pin area is what took the hit... I think a 125 would have lasted a while ...
the newer progressive kits can extend reliability.
If used in conjunction with todays controllers / fuels / turbo's ... it can be a real hoot ...
I've seen some pretty neat things being done with small motors .. huge turbo's .. with 300 hp NOS hits to get the car up on the turbo ... its impressive what modern day progressive kits can bring to the table.
The Supra Guys swear by Nitrous. From my own personal experience (Hot Air and 83 Carbed Turbo), NOS if properly used is great on a Turbo car. If your TUNE is NOT RIGHT, you will find out quickly. 35-125hp should not be a problem unless you are not getting FUEL. I have never seen anyone outside of Ken Duttweiler and the Resident Mad Scientist, Don Wang use more than 250hp. Don uses NOS to get his big turbo to spool. It turns off at a certain rpm. Duttweiller had a fogger setup on his DFI GN. Not sure of his setting, never were disclosed! Wtih NOS as a power adder with a Turbo, you have to really understand fuel and timing. More fuel, less timing. On a Hot Air, NOS is worth more than it would on Intercooled car. Hot Air charged air ranges from 260-300 degree. Spraying NOS brings temps down into the 130 degree range. Even with a 35hp shot, you now have 50hp. Bear in mind, you also picked up 2-4lbs of boost.. So, with a stock Hot Air being 200hp, spraying a 35hp shot now = 250hp. You must compensate fuel for the extra hp, and the extra lbs of boost. At this time, timing is not a issue. Any thing above this, you would need to consider getting a chip to reduce timing. Hot Airs DON'T like alot of timing. Even if you add a intercooler to a Hot Air, they don't like timing.
With the "new" emergence of E85 and TT chips, I believe you get up to 150hp (worth 225hp). XFI, progressive controller, or some form of Management unit could meter the NOS. But the big question is for how long. I sprayed (75hp) my T Type for almost a year and half. I only had issues when I stepped up to slicks (street raced on BFG R1's) and red strip convertor. BQ Tranny started to slip.
There is a board member I followed for a while, I believe his name is Kevin Bright. He strayed his 9 sec T Type. I believe he was using XFI to control his NOS. I am not sure of the amount he was spraying... I can remember Duttweiler was spraying his 4.1 DFI GN into the 10's and also into the 9's. So NOS can be used efficiently if you are on your game! The Import Crowd is still spraying Turbos...EKanoo 6.15 @230, BOOSTLOGIC spray 200hp to spool Huge Turbonetic's Turbo.
