Page 133 in the November Car&Driver has an article that test an automatic GT with regular 87 fuel and then with Premium 91 fuel and says that the GT is .3 seconds quicker in the quarter and has 2 RWHP more when run with Premium. The article also states that the GT has knock sensors.
I dont think that the GT has knock sensors--nor does the Bullitt--am I correct?
And the article also states that coolant temperature differences between the two test on the same car was a factor in the how fast the car was and how much horsepower was made. This seems to negate the premise of the article--that the grade of fuel has an effect on the performance of the car. What confuses me is that the coolant temperature wouldnt have been that different--if the load on the engine and the engine RPM was the same during both tests on the same car. The ambient temperature would have an effect--it would effect the total timing advance of the car--but I cant see how the coolant temperature would be different--even if the ambient temperature was different( except for extreme ambient temperature differences). What do you guys think?
