What size injectors...

...should I buy? Currently I have a 99 SS with Hooker Longtube headers, true dual exhaust, lid/filter, and nitrous(dry kit). I plan on getting my car dyno tuned soon but I figure I might as well upgrade my injectors now since it will be getting tuned. I would like to safely run a 125rwhp shot of nitrous, and I plan on getting a cam soon but then I will switch to a 75 shot of nitrous. So basically what size injectors would I need to run a cam, 75 shot of dry nitrous, plus my mods above? Would 30lb SVO's be enough? Also I am assuming I would need to upgrade my fuel pump, do I need a new drop in pump or will a pump booster be enough? Thanx for the info!

Re: What size injectors...

I have a TR224 setup and a 100 shot of dry nitrous and was running as high as 115% duty on the gas with my stock injectors. I promply upgraded to the SVO 30#, which btw are rated at 36# with our fuel pressure, and now see about 70% max duty NA and 80% max on the gas. I feel very safe with this setup and did notice a gain in performance/response. Hope this helps.
