well theyre already in the mail, i dont know who to take opinions from anymore...it seems some people think honda rods wont work, others say go 8.4:1 comp and some say 10.6:1...all i know is that the guy i ordered these off of off HT that has had his shop for years and done buildups and repairs on Honda motors for years says that the loss of power from goin from 10:1 to 9:1 will be so minimum that it isnt worht it, plus the 9:1 makes things alot safer under boost...im not going for a all out crazy fast car, im looking for a SAFE quick car in the 13s somewhere, if i can boost safely at 8psi and achieve that, im happy...but thanx for the ideas and advice anyway
