Hello all,
Greetings from Baghdad, IRAQ.
I Got few questions for you Corvette Experts. Please try to give your input for all questions. I really would appreciate it.
I got 07 Z06 and i am in process of buying Procharger. Now, i know i can safely run 4.5 psi (produce estimated 580rwhp).
My Questions are:
I was planning to run 6psi on my 2007 Z06 (looking for 620rwhp+). I dont plan to abuse and pedal to metal all the time, but i do plan to race every once in a while (1/4 mile, circular tracks).
1) Can I safely run 6psi (with tune ofcourse) if i dont drive this beast like an animal every single time?
2) What should i replace internally to add additional protection to be able to run 6psi? Valve springs, what else? (but not spending too much money at this time on internals, this is different project down the road)
Eventually, i plan to drop the compression and run 10+ psi, but not at this time.
3) Also, while I am doing valve spring change, what cam do you suggest i install for maximum power gains but keeping the car as a daily driver and reliability is a must?
4) With this mild to aggressive Cam and 6psi + long tube headers/X pipe and Tune, I am looking to be around 620-650 rwhp. Is this do able?
Thank you very much folks, I look forward to returning to states soon and working on my car.
Step 2, down the road will be interesting where i will try to build the engine, drop compression ratio and run up to 14.5psi looking for 800+ rwhp. But this is long term project. (need to save more money for this step)
Thanks again,
Be safe and see you soon somewhere...

Redbull, you've stated "keeping the car as a daily driver and reliability is a must". It pains me to say this since you must be living in a shit hole over there in Iraq, but if this is really a MUST, my advice is to save all your hard earned hazardous duty pay, and do NOTHING radical to your Z06. When you get back, just enjoy the car exactly the way it came from GM and you will not suffer the inevitable adverse consequences of severely compromised reliability and every day driveability. Get a set of floor mats or a full width rear spoiler if you want to spend some money on mods, but don't screw up a perfectly good LS7 just for more braggin rights. You already got plenty to be proud of and I'm not talking about your Z06. BE SAFE!!!
You can probably run 6lbs of boost but understand that you're pushing the envelope and there's no guarantee that you won't have problems. 11.5 CR is not the greatest setup for much more than minimal boost. You also have non forged pistons that are exposed at higher boost.
Under most circumstances, the cam you choose should not be very aggressive with this type of FI application. Choose carefully....
If you don't want to switch to dished pistons or swap heads at this point, you can lower your CR just a little with thicker head gaskets. Might be worth it if you're going to push more than 4.5 - 5 lbs boost but it still is not a guarantee.
Once you decide to that you want to push it to the next level, let me know. There is much to change and swap running 800rwhp at the track and it's not just your engine components. Get your checkbook ready....
Redbull, well I know virtually nothing about mods, all I want to say is Thank You for your sevice, be safe, and get home soon so you can enjoy that car everyday...my friend and Nam veteran said something years and years ago that has alway stuck in my mind, which says it all.."Freedom has a taste the protected will never know"...Thanks for helping keep it that way for all of us...df

I'm gonna jump back in here one more time for 2 reasons....
I know that you want some honest answers on the buildup for your Z.
My son just got his discharge a few months ago after his second tour in Iraq and I understand the need to have some goals and something to look forward to that helps you keep your sanity while you're over in that shithole.
I'm going to partially agree with dsinned about your build. The butt-o-meter difference between 580rwhp and 620rwhp is insignificant unless you are taking it to the strip regularly and going for specific times and trap speeds. It's certainly not worth putting your engine block and internals at risk for tha extra 40 to 50rwhp (and yes, at around 6 to 7lbs boost you can obtain 620 or more rwhp).
Where I disagree with him is that the Procharger P1-SC package at 4.5lbs of boost has proven to be a very safe set-up for the C6Z with headers and a good tune. It'll get you 10's at the track with good tires and some practice and still is very drivable on the streets. To hell with bragging rights about a few more horsepower.

Just want to add a dose of reality here. Neither a P1-SC nor a D1-SC will get you 800+ rwhp at 14.5psi. Not even at 18 or 19lbs boost will you make that sort of power. This is a whole different level and unless it's going to be a 'showcar', only a careful build and some extremely top quality parts (engine internals, heads, fuel system, ignition system, drive train, etc) will keep it on the road. You're not looking at chump change here.
I will agree with most of you and I think at first i will go ahead and run safer 4.5psi, install my KooKs long tube headers and Xpipe and tune it.
Keep that set up for a while until i decide that i want to mess with internals of the engine.
Having that much power will be fun for a while.
I really would like to do cam and valve springs at least at some point down the road. I will run search on this forum and see what cam produces how much power and what cam is good for supercharged engines.
If they can produce 40-50rwhp - calculate the cost with installation and then ill determine if it is worth doing or not. (OR just wait until i save nice amount money and do it all right first time - lower CR and run higher psi - which is what i will probably prefer)

Mike,
Do you feel running a methanol system is a worthwhile addition to keep things safe? I don't recall you ever suggesting to this mod, so I'd like to get your opinion.
Well, reading all of the suggestions and VERY helpful input (Mike). Would the stock block be fine to use if I were shooting for 800+ rwhp!! Redbull and I work together so we are talking about this everyday! Not to mention how we cant wait to get home and just DRIVE our cars! Like you said to get the HP im looking for, its definatley gonna be a complete internal swap, heads, tranny, and rear end. Thanks for all the help!

Don, a good meth setup definately can provide a safety cushion for someone pushing the edge and even protecting against that one bad tank of gas.
I've been running race gas so long now that I sometimes forget to mention the advantages of a meth system.
Thanks for reminding me!

IMHO no, the stock block is not ready for 800+rwhp.
I had a very good C5R block that I just recently changed for an LSX iron block because we thought we might be pushing the envelope (and the C5R is a much better block than the LS7 block). We talked to some people at GM and at Katech before making that change.
Once again I have to temper my answers by saying that a showcar can be built much differently than a car you're gonna put to hard use on the street or track. If a person is building it just for bragging rights then the quality of the components is not nearly as big an issue. All you're trying to do in that case is get a couple of dyno passes without it blowing up and you're in like Flint.
If you're going to run it hard, the answers are different.
This is will be my daily driver and i will race it once in a while at 1/4 mile tracks and circular tracks. I will run it hard once in a while thats for sure. I will not be driving a beast and babing it. NO WAY. If i am paying a nice monthly payment I will play and drive this car the way it should be driven. (If i pay, I will play)
AT FIRST:
I will go ahead and run 4.5 PSI and install Kooks Long tubes and XPipe and get it tuned in quest for 580-600rwhp (maybe port TB and Intake to squeeze few more hourses if needed to get to 600rwhp).
I am not just looking for a dyno queen - thats for sure.
BIG PROJECT: (12 months down the road)
I will look to drop CR and will be buying all internal parts needed.
I will look for a CAM that will go well with supercharged engine.
I will look to run 10+ psi at that point.
I am sure at that point it will be good idea to think about transmition, rear end, drive shaft, and other components being replaced or beefed up.
but here near term, i will enjoy my car suprcharged (4.5psi) with exhaust being upgraded and tuned and thats it.
Better play it safe for now, but as soon as i am done with this move, i will be planning and calculating my BIG PROJECT.
Thanks all again
Cant wait to be home to enjoy my Z and to destroy 1FAST02's car! Ohhhhh.
Take care

I'm Not trying to highjack your thread but I am curious as to what made you look at force induction as opposed to an N/A set-up.. I am on the fence whether to go with an FI set-up like what you mentioned or a N/A set-up for my 2006 Z06.
I am looking for max power possible out my Z but to keep it as reliable as possible. So, i will replace internals too but not at this time.
Other reason is my previous cars were all natural aspirated so i wanted to do something different for a change.
I got a good deal on this Procharger and then also it is easier to install. Installing procharger is way cheaper and easier then replacing heads/cam, valve springs, and then installation cost, etc...
For now i am going with supercharger due to that reason. However, I do plan to go big and replace heads/big cam, drop compression ratio so that i can run more boost out of my procharger, etc...
Eventually i am looking to do all the internals as well, its just i wanted to start with quick power adder first this time around. I will get to heads/cam and other internal parts in later time.
I am eye balling LG G7X3 cam. LG website has this cam with their long tubes rated at 530-540rwhp with out other mods. Which is impressive.
I will see if i can squeeze that into my badget and get that done now along with procharger and long tube headers in quest for 600-650 rwhp.

Let me repeat this once more so it doesn't get lost in the shuffle....
I don't know the specs for the G7X3 cam, but a rowdy cam is very seldom a good partner with a blower application.
Talk to Procharger or tuners like ECS, MTI (Atlanta), 21CMC, etc and see what they recommend. You might find you get less hp, certainly less torque, with a rowdy cam and a blower than with the blower all by itself.
I wouldn't be so kind in my description.
