New to me 427
So i recently Picked up an 86 gt with a 427 stroker and 2 speed power glide. 13:1 compression (what he told me) 205 lbs of compression.
He said he had been running 50/50 race fuel and pump fuel.
I ordered 3 bottles of torco race accelerator octane booster. They state i can use it to up 91 to 101. That comes to about 50$ total for 10 gal of gas. Race fuel seems to be triple that around here. Is this safe to do? Will i hear it ping with it being so loud? i only plan on using this mixture for street use not track.

191 PSI.
Atmospheric pressure is 14.7 psi rounded up, and the compression ratio is 13:1, the equation to solve for
the psi is (14.7*13)/1. Therefore, the answer is ~191 psi.
With a compression ratio that high, you need 110 octane to keep it from detonating.
93 octane is only good to 10.5 - 11:1 - You MIGHT be able to get away with a mix of race and 93.
Mazda's new I4 SkyActive will be a compression ignited GAS motor, and it has
13:1 compression. 13:1 is where diesel motors start on compression ratio...
