hi all, im goin to be gettin a 1.7 puma engine for a race car. i need some advice on tuning it up. dont really want to bore it to a bigger cc. can i gain more power in changin the length of the rods? will this change the compression of it? there will be a steel crank and rods goin into the engine. any other advice of anythin else i can do to the engine without spendin a fortune. also wots the difference in the racin puma engine to the standard 1?

 

A Passion For Power ill help

 

i dont think they are paticulary tunable,just over 120bhp as standard,built by yamaha i believe.Seeing as the racing puma only had 150bhp,i expect you have to spend quite a bit to get decent power out of it...

 

wud only be lookin at gettin about 200 bhp, shudnt be too hard to get as previous engine was 1.6 with 190bhp. any body know anythin about length of the rods? will changin this give more power??

 

any more help?????
