My initial thoughts on this would be to make some clear (as to not detract significantly from the look of the car) body panels to improve aerodynamic efficiency... but I have a separate thread for that http://www.6gc.net/forums/index.php?showto...mp;#entry928769
I post here however to discuss engine mods. Any ideas or thoughts on this? I was thinking of maybe advancing the ignition timing a bit to burn hotter, increase hp and hopefully mpg, but idk. Does a good CAI help? or a larger O.D. exhaust? What have you guys done? --------------------  |

it would reduce hp actually but not by much. while the genereal idea to reduce backpressure is by increasing the exhaust diameter, you also want to have smooth unidirectional exhaust flow which is obtained by having the ideal size diameter. larger diameters will actually promote turbulence and CAUSE backpressure.
