Both made 515-520whp with just a flash. However, one car like to run 11.8:1 at redline  , while the other made better power running high 10's. Each vehicle is different. |
Turbocharged cars have completely different A/F and timing requirements versus naturally aspirated cars. You can't compare them at all.
