Im at about 9.4:1 with -23cc Wiseco coated blower pistons. At least the CR i calculated to to be with 70cc chambers. I run Torco Accelerator blended with 93 octane for an in tank octane of about 95-96 octane plus the meth during summer. Car was tuned with meth turned off.

Im only 14psi now on my little D1SC but am about to pull the trigger on twin PTE6766 turbos running up the boost to 18 or so and a little over 1000rwhp.

Just a street car that was built to run down ZO6s and ZR1s on the road course a couple times a year
