QUOTE(maddriver @ Jan 19 2007, 12:17 AM) with that kind of overlap, u can expect the power to come from between 4500rpm to 7500rpm. u might lose some power on the low end, but gain gila on the higher end of the rev range. what's the lift like? the 288 is the duration only.  yeah u're rite i can fell my car accelerate during high rpm.anyway i didnt know this is half raise,full raise or whatever.this is the cam specs INLET EXHAUST total duration-288 -288 max camshaft-6.30mm -6.25mm max valve lift-10.10mm -9.98mm valve opens-38 BTDC -68 BBDC valve closes-70 ABDC -40 ATDC i dun understand what these means.anyway tx for helping!  |
