Default So C7 HP guess

I got a 1LT Z51 C7 2014 stingray.
Have a ECS 1500sl kit
E85 flex sensor
LT4 Z06 injectors
LT4 Z06 fuel pump
ARH LT
Snow Performance Meth kit twin nozzles
And fresh tune, running on E85

What does everyone think the power is going to be made? Haha

I started to ask how many lbs of boost. That's enough boost to make atleast 800 I'd think on stock cam.

At 16psi 800 for sure.

My advice is to not do the snow kit though if you can avoid it. I had the snow kit for about a year and had nothing but issues with the bad push lock fittings and nozzle leaking. Went with the Alky now and couldn't be happier. At that HP the last thing you need is a meth system issue.

Good luck with the build!

Thanks brother, the snow kit has been working great so far no complaints on my end. Ragin Racin installed it.

Agreed completely, be careful, meth is fuel! Thin plastic lines are for air shocks IMHO.

Agree, that's why I wanted to go the safe route with e85 and larger injectors and pump. The meth is literally just a secondary precaution and to lower the IATs

What % E85 are you able to run before running out of injector duty?

Well the LT4 injectors are about 20% larger then the LT1s so hoping to run at least 75% before maxing, but won't know til I tune.

I thought the max PSI for a 1500 was 14lbs is that not correct?

I'm at 860 @ 13psi, however the cam really helped the torque remain flat after 5k.

That's impressive brother, so the cam really made that much of a difference? What's your injector duty cycle at?
