Will a 250 shot be INEFFICIENT on my set up....? I know it will make it a little beast.....but how much am I wasting by having my old style LS1 top end parts....?
I still have ported "old ***" LS1 heads that only flow 304cfm@.650.....stock ported TB....and ported LS6 intake.
Iron LQ9 390ci at 10.8:1 cr
other info in sig.................................
I'm thinking dual stage 300. (100/200)
Or maybe a 250 shot.
Either way......am I choking the hell out of it...in a bad way...?
Or will it be just fine and make sick power....
I'm just wondering if I really have to spend another $3,500 on an LS3 top end for better airflow....(heads, TB, intake, etc)

No.
We have flowed 200-300hp worth of nitrous through stock unported "LS1" heads on 2 different cars I know of personally. (One stock cam and one nitrous cam car. Lower dynamic compression would allow you to cram more nitrous in too, but I don't really think you are going to be restricted with the setup you have now.)
I wouldn't be too concerned about it.
Thanks,
Garrett

Personally I would do the ls3 top end if it's in the budget. To be honest though u can jam 300 worth of nitrous threw those heads no problem. The only part u need to be concerned about is getting the extra heat and pressure out of the cylinder that size shot will create. This is were a really good cam guy comes into play.
For $8,000 I can just do the Huron Speed T4 single turbo kit with A/C. Make 900 RWHP.
But I really just decided to spend $3,500-$4,000 on modding. Spray seems like the cheapest route to a lot of HP.

Will a 250 shot be INEFFICIENT on my set up....? Well....I would like to do both....the LS3 top end along with the dual stage. But now I am looking at more than doubling the cost. Upwards of $7,000.
For $8,000 I can just do the Huron Speed T4 single turbo kit with A/C. Make 900 RWHP.

A bottle fill normally runs around ~45$ to fill depending on the area. You will consume 8/10lb every 10 seconds per 100hp of nitrous. You will get about 7-8 good useable lb's out of a 10lb bottle before it needs to be refilled, and then at that point you are only buying ~7lbs of nitrous instead of a full 10.

8 to 10lbs of nitrous per 100hp for every 10seconds??
