No need to up the boost. Just tune the meth in and watch the gains!

Wait for the built motor to up the boost. Like others have said, I'd even turn it down for the time being. That is, unless money is no object.
Yup, killed the rod bearings and floated the valves, ringlands on the pistons were perfect ( a few custom valve reliefs due to valve float though) though

lasted about 15k miles at 10-17psi on the stocker.

yea, we had already been building a 370 for his car for probably a year of collecting parts. Then Zombie goes and runs it low on oil(it had a leak that he was procrastinating to fix).............but the new engine was basically already done, with a used z06 cam, used diamond pistons (that a shop told there customer was bad and sold him a new engine).

So far......I havent hurt a stock engine with boost. Will it happen, sure cause things do go wrong.

Sounds like a good idea to keep the boost at 10psi max on meth. I only run 13psi on 91 octane on my 8.7:1 built motor for safety reasons. Just make sure that you continually babysit it.

Keep in mind, you'll PROBABLY be better off running 10psi on meth and putting in a little more timing if you're safe running 12 without meth right now. May end up making close to the same rwhp after cooling off the charge and putting in some timing! Keep us posted!

thats the biggest thing hindering the car right now is the lack of timing and the fat rich 10.5 afr
i bet it makes more power at 10psi than 12 psi too
at full boost it runs 12 degs of timing and it makes 650+ rwhp
its traped 128 in the 1/4 with 1.9 60ft but its time was only 11.68
so i have some bugs to work out
