forged pistons 9.5 comp,the shot added 134rwhp on the dyno,guessing the 150 shot jets,hard to tell when you don't follow the instructions and start to square up the jets,i would give you exact numbers but the car is now gone and working on the lq4 68 firebird,i ran very conservative on the bottle and enjoyed the gains without pain,my buddies running two, three, and four stage systems were fixing their cars every other run,too expensive for me,will help pit for a four stage 69 camaro that runs 7.0s in the quarter in a couple of weeks,hope to get some video,will post if so,

I'm running 103 autolites at .035 with zero problems. I pull 8 degrees out on 150 shot. My times don't seem to change when adding more timing but I can't say for sure I stay hooked, my 60 goes up 1.44 instead of 1.39 and the mph doesn't. I run 50/50 mix on race fuel and premium. I have pulled a lot of plugs and cut them up with no specking or anything so I'm happy. I have wondered about pulling less timing for race fuel because we all know that the NOS timing pull rule is usually for premium ... not the 110 race fuel or mix. However I'm not interested in testing the boundaries to much on my own vehicle.

It's not that. It has CRAZY amount of lead for vehicles in it. Even though its called 100LL (low lead) that means low by aviation standards. It also is lighter than regular gas and therefor must be run richer. I ran it in my solid roller 414 for a couple tanks and didn't like what it did to my oil and plugs.

I'm running a sniper kit. Its only adjustable to 150. I'm running the 150 ones, I don't recall the sizes right off, I will edit tomorrow.
The line on the sniper and solenoids are smaller than yours. Also I tried a High flow valve bottle, a buddy of mine had and my times didn't change at all. I'm just letting you know that as a "In my experience thing"... I'm glad I didn't have to buy a high flow valve or high flow bottle trying to make it go faster. However, all that could be just because of the limits of the lines solenoids etc. It could make a diffence on a cheater system. So if you get a chance to swap them out let me know what you find. I have 50+ passes on mine on the 150 shot. Pulled the heads recently making some mods before dropping the engine in the Fairmont I am building. Everything looked great inside.

The cheater instructions show to run the jets "square", but most of the nitrous experts on Yellow Bullet including Monte from NOS said to run an 8 to 10 spread with a larger nitrous jet than fuel. I just wanted to know what your jet spread was and what your plugs look like after a pass.

I think they recommend squared due to fuel pressure, timing, set-up, ect, variances they can't control and a little fat is a good thing sometimes. If you're off on the tune...it's better to be on that side of things....too lean and you'll be draining aluminum out of the oil pan.

Theres a great writeup with pictures on dragstuff.com on how to read the plugs and the strap. If you want to take it to a science level. Definitely a little rich means a little more forgiveness for our stock pistons.

With todays pistons the big thing that you have to worry about is knocking it. Make sure your timing is right and I would start with taking out 6 to 8* with 150 and work up from there. I would also make sure you have plenty of octane in it. I have always used Xylene and never had a problem.
Hyper pistons can put up with allot if your tune is right.
I helped tune a Mustang with a stock shortblock (hyper pistons) that made 240RWHP N/A and 470 with nitrous and it was together for almost 3 years before it split the block.
I also had a 302 that I ran two plates stacked because back in the 80s you could only buy a non adjustable 125 kit so I had two.
Never had a problem with that either.
Your car is going to fly with this kit on it. Just make sure your fuel supply can keep up and keep a close eye on the plugs.
Good luck and have fun.

I am going to test the fuel system by running a bypass hose from the supply side by the engine to the return line with a nitrous fuel jet as a restrictor and then make a pass or two to make sure it can maintain the fuel pressure.
