High compression = more likelyhood of detination at the same boost level as a lower compression rotor.



it should make some more power though

 

balancing is the trick, on a 13b you can buy the couterwieghts.



20b is different

 

yup. as long as you use S5 or FD rotors you can still use stock counterweights. Once you get into S4 rotors, you need to have counterweights made.



neil

 

Yep so if i get a 20B for my 1st gen since its sugh a light car i wont mind having a all N/A engine 3 renesis rotors with a custom lighten E-shaft from guru racing, custom lighten pullys, electronic distributer, custom intake manifold from magnus that clames 40hp, and a exhaust to match the power and so on i say ill spend 12G on everything and get a 300hp+ reliable, efficent motor....what you think

 

cant you use the complete rotating assembly from an S4?



any advantage from S4 as opposed to S5?

 

not on a 3 rotor, they only made the 3 rotor with s5 internals, thus theres no counterweights for anything else, its gotta be custom

 

how do the counter wieghts differ from a 3 rotor to a 2 rotor? are there more than 2?

 

ok, i did a research.... s5 are 9.7:1 and s4 are 9.4:1

 

there are still 2 but since theres an extra rotor to balance out, the cw's are different sizes

 

so no one cares about an efficent reliable, 20B pushing 300hp?? with lighter internals and pullys that thing ill get to max HP in no time better than a F1 hopefully
