Whats the deal with back cyl starvation under a 150 shot?
So i was talking to my buddy who works at a performance shop the other day and he said that a 100 shot would be about as big as i could go without starving my back two cylinders. He said under a 150 shot, bad things would happen. My question is first of all, is he right? secondly, 50 - 150 shot seems to be the standard in relatively stock applications for these cars from what i have read. Thirdly, I have tried to take as many precautions as i could, ie racetronix w hotwire, BR7EF plugs and pull 6 degrees of timing. Even with those things done, and this being a wet kit, would my back cylinders be starved? Do i just spray it once and then check the plugs?

your buddy isa little off. the reason guys burn up 8 is not due to lack of fuel its the hot cyl on a ls1. now when you exceed what the stock rails can do at about 700fwhp the crossover pipe cannot flow enough. all small block chevy motors run hotter on the even side and the ls1 runs even hotter on 8
250 can be done on stock motors if you know what your doing. 150 is fine... read the plugs....

with a stock pcm theres not much you can do other than tune off #8. you will be giving some up over individual cyl correction. IF you had a dp you can put 1-2 jet sizes lower in 8, 1 lower in 6 then add more timming and it will more than make up for the smaller jet on 6,8...
