225 shot was fun! Dyno numbers on a 225 shot and new all motor best.... New dyno graphs to follow......
On motor made 450rwhp/404rwtq, and on a 225 shot made 621rwhp/707rwtq. 20 degrees timing on bottle, 28 degrees on motor, full belts, heavy *** 60lb wheels on back, 4.10s, 12 bolt, etc..... 98 octane in the car (roughly).
This is all on stock fuel system (except a Walbro 255lph in the tank), 10.8:1 compression ratio, and the A/F is in the mid 11's on bottle, mid 12's on motor. The spike in the graph is from a 225 shot coming all at once w/o a front mount regulator. I won't ever spray this much at once on the street or track so I shouldn't have a lean spike nearly that size ever again.
I think I've maxed out my -4 nitrous line, because I only gained 10rwhp going from a 200 to a 225, but picked up 90rwtq and was running richer than I was with th 200 shot.

it likes 31* best.
With the X-3/114 run 31* on motor and 24* on spray.
I would also add 4% fuel when spraying.

I'm not going to bother changing my N/A timing for the track since I had no intent on running N/A at the track, and I'd rather have it where I need it for daily driving.......and I'm sure I could have retarded a little less timing on bottle, but I'd rather be safe than sorry with such a big shot. I'm not a big fan of spraying such a big shot via a standard wet kit to begin with. I'm already concerned about leaning out the rear cylinders. I'm also running on TR-6 plugs which probably should be a step colder to be on the safe side.
Again, this is my daily driver, so better safe than sorry IMO

. I'd like to see 700rwhp/750rwtq if that's doable, but we'll see. The feeling of all that torque is friggin awesome; I had to pick up some Depends on the way home
. Makes me wish I had a single turbo on the car so I could feel it all the time!

Sweet #s man! Congrats. Glad you got the nitrous problem fixed. Now go make some more supra racing vids so I can live vicariously
BTW You still spin that thing to 7400rpm? If so.. Why the G5x3?

I only spin it to 7400rpms in 4th gear if I'm getting close to needing to shift into 5th gear during a race. Otherwise I shift closer to 6800rpms.
I had the G5X3 cam when I had a stock bottom end and only spun the car to 7000rpms.
