Did you finish this build yet? If not it all depends on your parts and tune. 12 to 1 is pretty high, obviously you'll be on race gas, if you've got all forged internal you should be able to go 150 really safely, with the fogger setup it's a little more expensive to set up, but will work a little better, more even distribution, don't forget to pull some timing out, 2 degrees for every 50 horse of juice. Have fun.
