New Injector and Next Upgrades??? What are the specs of the stock Z06 injectors and what are the maximum usable/realistic, power they can generate.
What are the next two (specs) likely injectors upgrades and there respective max power.
Need help with my possible next steps or upgrades:
If I upgrade to the F.A.S.T. LSX intake, what is the typical power increases- I know the company says 10HP from a stock LS6 intake, but what is typical from a modified car. If adding a new T-Body(current ported t-body)which is best, going to the 78mm, 80mm or 90mm package. what are the power gains- is it cost effective?
Next, is the Meziere electric water pump- is it really 5-10hp on modified engines?
Next on my possible list is -MSD Blaster Coil for LS1/LS6, I'm guessing this might not really do much, if any thing, but don't know????
Current set-up:
I currently have a very light cam, by most on this forum- VHP 062 ASP-KICKER 2(using their or Crane's 1.72-1.80 variable rocker's)- 210/218 .551/.551 LSA 112- trust me, this cam is under rated and has lots of torque down low, and mid range while peaking at 6100 rpm's and only dropping 15 hp 6100 to 6700(rev-limiter).
This cam/head combo(Patriot stage 2 head, Patriot Gold springs with upgraded Ferrea valves) has a minimum of 350rwtq 3K-6.3K, 380tq 4.3k-5.5 and peaks at 405. Not looking to touch or change the Patriot's.
The next cam I'm thinking(maybe), is still somewhat light by most- VHP 056-Boss2 216/224 .551/.551 LSA 115. Both cam's have an overlap of -10 and an overlap of 52 vs 53 at .004.
Questions:
1. Both cam's have the same .050 overlap- I'm thinking idle quality should be the same. I'm not looking for a choppy idle. I like the idle as is, while it has a very light or slight chop. I'm not willing to move to a 224/224 LSA114/112 because of the chop. I want to keep the car as a sleeper- if not, the wife will complain! I think some of you out there can understand this.
2. Will/might the cam alone pickup 15-20hp, if so what tq might i lose, if any??
3. I'm thinking everything listed except the MSD coil, should give me 40rwhp and maybe 15rwtq?
4. Since my Patriot Gold springs have 2.5K, by the time I might do this, i should/might have a total of 5K on these springs. I'm thinking I can re-use these springs without any problems, since my cam lift is nearly stock at .551 and the Gold's are rated for .650- i believe.
Does all this sound right?
Costs without the MSD coils- With professional install and re-dyno tuning 4K-4.5K.
Lastly, please make any comments and/or recommendations.
Goal is 455+ rwhp- currently at 425.
Thanks'

Boy it would take a book to answer everything. you might want to consider spreading questions out and selecting different areas of the forum to get the experts on each item/area. You'll get more detailed responses.
The stock injectors are 28lb'ers. The math for figuring injectors needed is:
(projected HP x .5) / 6.4 = min injector size to meet 80% rec duty cycle
The FAST intake is for higher rpm engines leaning towards racing imo. Can't hardly beat a stock Z06 intake for most uses.
Just put a 100hp n2o kit on and save money and make more power when your ready?
