09 SSTC 75 Shot?
Currently deployed and my car is sitting in my local shop. They want to hook up a 75 shot. Just wondering if anybody has tried a 75 shot on the TC?

A great guy with a LNF Kappa back in begining of 2008:
For hole story:
Engine build - Pontiac Solstice Forum
i started with a 75 single nozzle in the cold side charge pipe. worked fine. i then put a purge solenoid to the intercooler and moved to a 100 direct port shot. i popped 4 holes in the intake mani, tapped into the schrader on the fuel line leading to the mechanical pump and sprayed away. then in 50 horse increments, i worked up to a 200 shot. (lemme tell you what, 24lbs of boost and the spray make this thing a monster, i cannot wait till hptuners finishes that thing). now before you people all call me crazy, let me tell you that i was scheduled to go in for surgery in sept and knew i was going to have the winter away from work to play a little while i healed. so i got the monster jets out and figured a 300 shot would probly tell me where the weak point of this motor was. and it did. i'm figuring it took about 600 horse (260 stock, plus mods and boost, and 300 from n2o) before she let loose but heres the result.

75 shot is fine. I finally got the 100 dialed in perfect the other day after some misshaps, hitting the track tomorrow. Going to work into a 125 to 150 by the end of the day and let god sort out the rest. If she blows, no biggie, just hoping the clutch will hold together. Biggest bitch so far has been keeping EGT's in check. Lots of meth and lots of fuel and stock timing alleviated that though.
3 10's ready to go, can't wait.

I'm getting ready to install my nitrous kit this week. Looking to start with a 50 shot and work up from there. Where do people with the LNF tap for the fuel?

Here is an update on my case:
LNF Kappa (Opel GT) with nitrous
No nitrous
HP: 205KW = 274whp or 278 whp in metric
Torque: 430Nm = 317 ft/lbs
With 50hp shot nitrous from 3500rpm
HP: 230KW = 308whp or 312 whp in metric
Torque: 445 Nm = 328 ft/lbs
Difference:
- 35whp and 11 ft/lbs
Some personal notes:
Now I understand why I don't feel it when I spray on streets/race because there is only 11 ft/lbs difference.
Normally a 50hp shot should be 50 whp but because my bottle has no heater so it has way lower nitrous pressure (600psi instead of 1000psi) I get less power increase, also because the nitrous is less I noticed -10% adjusting on fuel trims so it runs very rich, with a proper nitrous pressure I will approach to 50whp.
I did over 10-12 runs on the dyno, I have played with AFR and timing on the high rpms but I didn't saw many gains so I went back to the rich baseline.
I'm about to buy a bottle heater and nozzles for 75hp and 100hp shots, depending how fast I will get that from US I will have more results updated.
