i'm focusing on vtec cause it's what i know ans because i've explained it on here 3 or 4 times it should be quite easy for me to write up something on it-- 5 pages, one introduction, introduce the basics of horsepower and torque, howe the engines achieve higher output and/or increase effciency. this lady doesnt know the difference between a wheel and a steering wheel as far as i am concernedso to say the least i'm not concerned at all.
