Hey guys I'm in the middle of a build and in the mean time I decided to spray my ls1. It's got a ported ls6 intake and ported tb, ms4 cam, hooker headers and tsp y pipe. Th400 moser12 bolt with 4.10's what do you guys think I'm looking at et wise with a 100,150, and 200 shot? I was thinking I'd be 6.8-6.9 in then1/8 and a low 10 in 1/4? Couple people have told me low 11 in 1/4. What do you guys think?

You are going to have to spin the motor 7000+ with anything over 175 shot if it is running correct. It should run 9.90- 10.20 on 175 and 9.70 - 10.0 on 200. Thats with raceweight of 3400-3500 lbs and if motor tune and nitrous tuneup are spot on and car 60 fts in the 1.38-1.45 range. If not you could be much slower.

Sorry but I'm a total newb to nitrous, why do I need to spin it past 7k for above 175? Also, what is the most a stock ls1 can handle? 300? Not repetitively but maybe once or twice at track?

I'm saying with the 4.11 , 28 in tire , that if the car if running and tuned correctly , that you will be running good enough to see over 7000 rpm through the traps if you spray more than 175. For example my cam only car , with stock 241 heads, same gear and tire , 3525 lbs would see 7400 -7500 through the traps on .078 jet or 200 shot. On .073 /175 shot it would run 9.90-10.0 consistent and about 7000 through the traps. Not to mention the cam you have needs to be spun to 7000-7200 to take advantage of its powerband. I have an MS3 and shift @6900-7000 on the kit on a .093 jet. Too many factors to say what a stock ls1 will handle, but , there are numerous people who have put 300+ on one including mine. I still have stock rod bolts also. I have seen people grenade one on 125 though.

ok awesome. again its just a play motor for now until my build is done but i may consider building it down the road and spraying the **** out of it. just wanted some ideas of what the car would do.
