Enough fuel for 1/2mi?
My combo is simple, ECS kit with restrictor in plus Alky meth kit. Z06 manifolds and full 3" exhaust. CircleD converter. Car dynos 672whp. We have a 1kft track near by and it went 8.5@122 on a 1.5 60'. It had a bit more in it...I couldn't get to the floor until after the 60'. So it's a 10.0-10.teen 1/4mi car. Fuel system is just as ECS specs on the kit when I bought it in 2014. So that's their BAP on a stock fuel pump. Do you that have ran this combo for a while think the stock fuel pump will hold it together for a 1/2 mi event? My tuner rocks and I fully trust him...and he told me 'no go' on a full mile.

you'll know if you lean out 
I had issues with the stock LS3 fuel pump although mine was weird. I went with an LS7 pump on the BAP and no issues. I'm at 640 RWHP using meth, headers, LS7 pump now, and a BAP and have zero issues.
LS3 pump now...my weird issue was long driving (anything longer than an hour) and I couldn't really get any top end power. It was like the car hit a brick wall. It didn't matter if I beat on the car or if I drove 70 MPH with cruise control on. The long driving would cause the pump to heat up enough that when the BAP commanded more fuel the pump basically said GTFO I quit. Showed an AFR of 17+
Needless to say that pump went buh-bye. It was very obvious the power cut when it happened.

I use a AEM failsafe wideband/boost...once everything is in the groove it's easy to monitor. I was just concerned about that lag time on what the AFR says and what's going on. I know to listen for audible ping as well, obviously.

I should have also added that's why I use a DashLogic. I've set it up that when certain parameters are met a warning shows on either the DIC or HUD or both. It helps when you have a piece of hardware monitoring everything and alerting you if something is off (boost, afr, knock, IAT, oil pressure, coolant temp, etc. etc. etc.)
EDIT: I don't know about everyone else but I'm too busy having fun rather than having my eyes fixed on gauges on every pull.
Having something else watch for me helps keep a piece of mind while I'm enjoying the car.

Do you have the fail safe wired to cut ignition? I'm wiring one up for a friend to a small little alarm

Yep.. dash logic FTW. You're right.. it isn't exactly easy to stare at a gauge during a pull, but dash logic will beep or warn you based on whatever parameters you wanti, if you set it up to

I'm going to look into the dash logic set up. I'd be nice to see knock retard...reminds me of my turbo buick days.

an ECS stage 1 fuel system is so cheap and easy to install I am not sure why anyone would chance it? and those are rated to I think 850-900whp if you include dual nozzle methanol
you'd PROBABLY be fine but since I imagine you'll push the car more in the future anyway why not just throw an external pump system on there and know its good?
dashlogic is awesome and well worth the price

Yea this is the route I would go I want beeping and flashing lights...maybe something that fires off the hazards via canbus.
Nobody has time to watch the gauge
