"yea i understand, with the track, driver and day to day variables. But i am questioning the bottleneck effect and exactly HOW BIG is this effect. If a I/H/E gsr "should" run high 14s with its bottle neck then "shouldnt" a I/H/C/E gsr run SIGNIFICANTLY faster since it has no bottle neck? "
To explain as easy as posible for you to understand. Yes it should be faster, But we have to go right back to what StyleTEG responded. track conditions, driver, tires whatever. All engines act different to diferent mods sometimes you just cant question the result of something not doing what its "supose" to do.
Example: The fully recarged batery "should" last 30 minutes as said in the manual but only last 25 minutes.
the other one last 33 minutes, and another one does 15 minutes. See where im going?
To fully answer your question yes its should be faster "if" your mods and car is exactly as the car that reported the times or numbers.
