I have a 2000 Z/28 M6 here is the set up I am building this winter, 228R cam, patriot ls6 heads, ls6 intake, LT pacesetters.
I also have 125hp of nitrous on the car already and a walbro intake pump, clo flo pac, and basic bolt-ons

I figure with out the nitrous the car will make around 430ish give or take (if I am off let me know) and on spary 500+ (I don't know if I will run all 125 with the other work done)

Will a 40lb injector be big enough for what I am wanting to do?

what size is your walbro pump? 255?

I would go to at least a 42# or 48# injectors and call it a day.

It is a Walbo 255, I have not put it in yet, its still in the box.

Last year on the dyno when I went to spray it with 120 it leaned out instantly and the hob swtich shut the nitrous off, I was just thinking that with 100K on the stock pump it was just not keeping up with the nitrous, does that sound right?

Also with the above combination mentioned does the hp numbers sound right? I am basing the size injector I need off those numbers

Assuming the nitrous is a wet shot, Bosch Design III 36 lb/hr @ 3 bar is more than enough for you. I can post the mathematical computation if you would like.

FICINJECTORS, http://www.fuelinjectorconnection.com , has dynamite pricing on these injectors.

I am sparying the nitrous dry right now through the maf, would it be better to set it up for a wet shot while I am doing everything?
I put the nitrous on last summer and for the simple way to do it was dry since it was a stock motor

A wet shot will get its fuel compensation right from the rail, instead of trying to enrich through the injectors.
