Should I go with a bigger shot? My current set-up is a 230x224 tr reverse split cam, headers, vilant cia, colder plugs, nx 150 wet shot, with wot switch, 3200-6200 window switch, 12bolt 3.73 gears, stage 3 4l60e with 3500 stall, walbro fuel pump, and misc. I am looking to get a nice time slip at the track in 2 weeks and was thinking about going with a larger shot. But still have a stock bottom end, and thinking about spraying out of the hole. What do you think?
I would try it since you got the pump, step it up to 175 and if all is ok, then try the 200. I have heard lots of people doing 200 on a stock tune. You should be OK especially since your window starts kinda high. I am looking to step mine up as well, just have to get the jets.
DUH!!! Step that up! Go up a couple jets at a time. If it breaks, that's what were all in it for! You'll never know how much power it can take if you don't break it!
I would purchase a Wideband 02 setup if I were you...check your plugs after runs, and run low timing+high octane.

risky? yes. definately failure? no.
Pour some higher octane fuel in it and you can run timing (I have a different application considering dual poweradder, but I run straight 103 all the time.) Maybe you could start using torco....
Just make sure you pull your plugs directly after a run (by directly after I mean DIRECTLY after, shut the car down through the traps (or street) and coast to a stop (you CAN throw it in neutral). Pull a plug and take notice.
I think with some straight race gas you shouldn't have a problem on a 200 shot, but than again, no promises. (better safe than sorry, have someone back off timing, they say about 1.5* for every 50 shot).

I would pull some timing if you were going to step up the shot size. also, i am not familiar with the exact cam specs you are running. Is that the Thunder Racing cam from awhile back? If so, contact them and see what limits you have with the limited exhaust duration. Just my .02 but i would keep things safe and just run the 150 shot.

I would go atleast 175. Just step it up slowly, get an A/F ratio and see how your timing is doing. Asuming they set your timing at 22-26* for the 150 shot you can run more nitrous with that. I run a 225 shot with my 150 shot tune, 24* of timing, 93/104 octane mix.. Like LS1eater said, just pick up some race gas and start stepping up the jets.
