I hate to admit it , but the 12 is an untamed beast . It will never handle as well thou....so take him to the twisties , and humiliate the guy there . Or you could "top speed" him.
Go the other way with yer gearing...he'll getcha off the line,but with the grunt of the Bad Bird, you'll overtake .
Or....put it to rest..once an' for all...TURBO.
Those 12's ...I dont know what the deal is...they should be hotter . 33 an' a half intake valves , left open for 300 degrees . Exhaust valves are bigger than ours too, and are left dangling for like 294 . The busa has in's @ 33 , and exhausts at 27.5 . They hang open for way less time too,276 and 259 .
I think its the stroke, its way shorter on a 12 , so , in theory , it makes it's power up a little higher . I think you'll just about always be able to take him is you short shift it a little....just a little . While his tach is climbing looking for peak hp , you'll already be in the next gear .
For some reason...which escapes me right now , the 12 should be makin' better power . It just doesnt. They didnt give it as many cubes as the Bird either . They wanted this thing rev longer an' higher, is my guess . Compression is higher on the 12 aswell...I think . I dunno...the 12 is down a hundred cc's...but the numbers suggest it should have more GO. It juz dont . No show = the Busa is way prettier
No go = the Bird is fasta
it's a neat topic . Bottom line.....
the busa was faster outa the showroom .
He gets cams....you get cams
He gets piped...you get piped
He gets turbo...you get turbo
you see.....now yer into hot rods . Who has a thicker wallet?
$$$$$$$$$ = speed .
