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? --------------------  |

lightweight flywheel will remove a lot of the rotational mass. this will raise your MPG a ton

So where are we exactly with what can be done? exhaust could go either way. Improved intake - only if tuned correctly and you stay out of the extra power advancing timing - viable, to what extent we don't know has anyone made any mods and tested at all? This weekend I am going to advance the timing to 14deg before top dead. I'll report what I find, as it shouldn't take me more than a week or so. like I said. I'm doing A LOT of highway driving lol. -------------------- |
