I have a 9 bolt BW on my car already .. 5 speed .. but instead of the 3.45s I have the 3.27s.. would I notice a big increase ?? will the 3.27s slow down my 1/4 mile et?

why did the 5 speeds get the 3.45s??

could not find an answer to this.. I did find something about the way the auto was geared ? but that kinda didn't answer my question ..

thanks!

 

Manual transmission cars typically get lower factory gear ratios because that buyer wants performance. A fifth gear (compared to a 4 speed auto) also gives a higher overdrive ratio in order to slow the engine down at highway speeds to preserve some fuel ecomony. There isn't a huge difference between 3.27 and 3.45 however.

 

Thanks for the info. . Will my car still be able to hit the 14xx in the quarter mile ? I'll be taking her Friday .
