Default Re: 1st build in the mail!!

thats great advice thanks alot! ive been doing alot reading today and i think im going to get a higher gear ratio, the hills bother me alot more than speed. i also need to learn alot more about exhast systems and expansion chambers. i understand the fundementals,like that along with exhast being expelled by the explosion, there are powerful soundwaves that reverberate and pull the extra spent feul out of the chamber, resulting in the efficiency i would assume. but in terms of acual hp increase i would have no idea. these also make them mch louder im told, which ma not be a good thing for me XD

what do you guys think of engine modification? is it worth the effort? does the life span/efficiancy suffer?

thank you so much for your patience with a new builder.
