ive had my rx8 4 a while now n it only has intake and a tune. ive been looking into underdrive power pulleys is it worth the money to get them and is there a nice increase in rwhp

 

no NA mod is actually worth the money in that sense

but I did get an under drive pulley and for what its worth, if you need every last tinnie bit of whp from your car, then go for it

the only noticeable NA mod is probably the short shifter or light flywheel

 

not such a good idea if you are in hot climate & sit in traffic a lot . Otherwise - yes I've found it to be a good mod.

 

brettus, are you in christ church? or north island

 

north Island - why ?

 

nothing.......because I have never seen an rx-8 in new zealand.....but I was in christ church though
