Daily Driving Issues?
I'm thinking about going this route but does anyone daily drive a forced induction Vette with this? I would be concerned about always having to be worried about something consumable when getting on it power-wise? As it stands without it I can just get on it and not worry about other variables.
Durability?
Car gets driven every day and I know the blower itself is a strain on the motor. How much more strain am I putting on it? Am I really making it safer at higher power levels thanks to the meth?
Thanks. I'm debating throwing this on before the 1/2 mile event later this month.

No issues here, just make sure you top it off regularly. Mines in the washer tank so it'll let you know if low anyway. As long as your tune isn't completely dependent on the meth, it's a great safety feature. I have my kit coming off my car, barely used if your interested.
Only reason is ill probably be going e85.

No issues. I top off in the garage maybe once every 2 weeks. I don't think I've ever even seen the low meth warning come on, but even if it did you know not to get on it or you are going to run out soon. Works great.
As others stated, no problem for a daily driver. The only issue you may have is not having your windshield washer if you use the tank, but there are work arounds for that as well. Heck of a lot cheaper then race fuel when you need the octane.

You might want to figure out what's wrong with your car before adding anything else to it. You never came back into that "power loss" thread, but I'm pretty certain it is a fuel issue. Maybe you've figured it out already?
Otherwise, meth is a great addition to a boosted car. If it's installed with care (with a proper sized nozzle) and tuned the right way, then it can most certainly make the engine more reliable while making more power. There are many schools of thought on how to set up a meth tune on one of these cars, so that's a big factor.
I'd probably nozzle it for a full point drop in AFR (i.e. 11.8-10.8), and only add extra timing when the IATs see a big drop. That's probably the safest way it can be set up.

I have a 1/2 mile event later this month so figured what the hell...you live once...maybe I'll do meth injection. If you use the windshield washer reservoir, about how many hits do you have of full throttle before there's concern about running out of it. How drive-able is the car typically if you were out of meth (esp under a load (e.g. boost))
Car is getting Wilwood Forge Superlites while at the shop.
Yes yes I have the car at the shop as we speak. He's troubleshooting the car first. I talked with him about it and he plans on fixing the problem before doing anything more to the car. We are thinking either a fuel pump issue or an ignition wire issue but it's still a work in progress.

You really need to be driving the car like a maniac all the time to burn through a lot of meth during regular street driving. With a MAP based system, the more boost you see = the more meth you'll use. I've never worried about my meth level when doing airstrip events. Top it off before I leave home, and never an issue.
How the car runs when out of meth is fully dependent on how it's tuned and how the nozzle is sized. My car is slightly leaner than I'd like with no meth using a single M15 nozzle, but that's the way I chose to tune it. With my boost level and poor pump fuel quality, I want all the octane gains I can get. That means running a little too rich when the meth is flowing, and a little too lean when it isn't. I won't ever try to run my car with no meth obviously.
You might want to run something like an M10 nozzle to reduce the motor's dependency on meth if you're that worried. Keep fueling how it is now, and just add the meth on top. There is little to no risk if you do it that way. Just depends what you're after.

Agreed with street, it is tune dependent. You can have it run with with no meth, but won't maximize power or results and you will run rich. Or you can have it fall on its face off meth and would know something is up. Many ways to do it.
Right now my car runs so much meth that with it off it basically doesn't run. When I was only making low 1000s it would make 910-920 off meth and then 1010-1020 on meth, but now it is tuned for meth on all the time.
