I'm out of injector at 90%. It's fine for now, but will need to change them out if I go for more power.

What boost are you at?

I made 720 with 60lb injectors, boost a pump, and meth at one time but that's about all that fuel setup had in it

I assume most of you guys are running 1:1 boost referenced regulators? I have the C6 style fuel tanks and replaced in the in tank pump with the LPE unit / walbro 450. With my modest goals of ~650whp on pump gas/meth, I figured I would be OK with the stock in tank regulator and constant 58psi fuel pressure. I think I may be borderline though with 60 lb/hr injectors since the effective pressure will only be 46-48psi.

the setup I mentioned above was on the stock style fuel system, my car is an 02 so the regulator is built into the filter... I have since ditched all the stock stuff and switched to a boost referenced return style setup

Good to hear that and thanks for clarifying. Despite the tank differences and C6 style being a pain in the *** to swap pumps, I think overall design and function is about the same. Was that on stock fuel pump (w/ BAP)? if so that seems impressive. Was the pump maintaining pressure? Or were you more so out of injector? Do you recall what nozzle size on the methanol and I assume pure meth? I'm guessing this setup was from a while ago, but if you remember, that would be great info for me, thanks!

it was a walbro 255 pump with a looped kenne bell bap so basically when it was on it was full tilt, dual m10 nozzles and 100% meth... it did maintain pressure but the injectors were done and I'm sure if meth were out of the equation they probably would have been done sooner... my tuner (Bret) recommended to go to a better fuel system if I wanted more power so that's what I ultimately did, fuel is not something you want to be cheap with or cut corners in my opinion

As the title states. I have a 2004 ZO6 with a P1SC-1. I have kooks long tube headers, high flow catts, B&B axle backs. Right now I am tuned on 93 pump gas. It still has the stock motor, from intake to oil pan. Has 42 lb injectors, that came with the kit. Makes 5LBs of boost now. Has the twin inter-coolers that came with the kit. I would like to do some work, to up the power. But would like to keep the heads and bottom end stock. I would like to install a blower cam, pulley change, upgrade the fuel system, injectors, and add meth injection. And I would like to stay, on 93 pump gas.
Is this possible? Can I get the HP level I would like? And still be street friendly.
If so would you guys share your engine combinations please.

tuning on the edge is just that, don't be too surprised if under high load the thing pops. LS6 is relatively high compression and the brittle pistons make for a tough combo when pushing boost
I would recommend exploring e85 as it's much easier to make power and stay away from the ragged edge of detonation which will hurt even a forged engine.
so my advice is spend the money on the fuel system and tune and if possible go with a flex fuel setup.
Also the aftermarket computers have more "safeguards" like o2 monitoring and EGT or even 8 channel o2s and the "alerts" can be tuned to save the motor before it pops
of course none of this is super low budge but I can offer up "dual fuel" which is pump gas with direct port meth injection to ensure good fuel distribution with a MS3 PRO for cheaper than a full blown conversion.
The MS is about 1200 and works well as a very intelligent controller that can even do the tranny now. It beats popping the motor and the alerts and meth dependent tuning go well together to keep the car from detonating under boost and providing the monitoring tools to make sure you aren't detonating.
Lots of folks push these engines hard and if you want a cheap way to go, take a look at a forged 4.8 with wiseco pistons that will punch out a reliable 900 hp (shameless plug)
to me e85 and alchy injection are the "secret sauce" and while the injector sizes and fuel pump demands go way up, that stuff is getting cheaper all the time.
The c5 fuel system is kinda a pain, so I ended up with another dedicated tank in back for the meth injection and another big pump (Julio Alchy) which is a great "entry level" and the controller box gives good control of the tuning provided you get it setup right (dyno and street tune). Let me know if you need some help. I have a ttix ls6 twin turbo in my c5 which has pumped out 800 at the tire, but it does have a forged bottom end and at that point the block and lifting the heads (17 psi) can become an issue. the after market heads (afr 225) have a thicker deck than stock and running good quality studs and an ls9 gasket works well if you don't mind pulling the heads.
and while expensive, porting the heads or running better heads is absolutely a great way to keep the bottom end alive as you flow more air (boost is just restricted air) at less psi and make more power and stay away from the edge of detonation.
hope this helps.

LOTS of folks pop ring lands on the stock hyper pistons from detonation even when tuned (bad batch of gas, injector, o2, bad hair day, ect...)

What blower/pulley size?
What size injectors and do you know max duty cycle?
What is your fuel system?
Running methanol? What nozzle size?
Hope you don't mind me butting in bada, I have a 03Z and similar goals... more info the better. Something else that may be a little different for us vs rest of the C5 section is that we have the C6 style fuel system. If you're just going to add an external pump then I guess it will be more or less the same end result. I put in the LPE / walbro 450 in mine in prep for boost.
