Us And Them
How many have done this? SP recommends we do this with the sp61gt, i'm looking into it but i wanted to see how many people have done this and their experiences.
as far as lenght is concerned, no, they aren't even length to begin with. As far as diameter, it shouldn't make a difference since they are unequal length anyhow. I'd say this is definately something good to do. I've done 2 of them and I hit 18 psi in 5th gear at about 2700 rpm on my 60 trim.Kyle87T said:Is it a big deal if the runners arent evenly matched after porting?
