I am just curious if anyone one of you guys who are running some of the medium to bigger sized turbos (to4r,gt35, gt40, t-78, af61 etc) and the racing beat duals. I really am curious to know if it would hurt flow/hp number compared to something more straight through with less bend in it (n1,jic....). Now I am hopign for feedback with those with hp numbers 425rwhp-500rwhp. Thanks in advance for any input

 

I will be running a GT35R and the RB duals as soon as the turbo kit gets here from A-Spec. I should have a dyno comparison of the single turbo with a MP and then with a HF cat in a 3" MP...

I have an old school Greddy SP 3" or 3.5" sitting in my yard...I could probably compare that with the RB but I dont want to have to add another hour on to my dyno time to do so.

 

I'm using the T4 GT35R and RB dual tip running 440+whp. R-magic has a T-78 and switched from the apexi N1 to the RB dual tip due to how loud it was.

 

thanks for the feedback...I a mean I had the JIC titanium (which I loved) but I simply wanted something closer to stock (looks) and definitley quieter without compromising any real flow....I figured I was over-analyzing the situation but I tend to do that a lot oh yeah and I run a t-78...

 

anyone else?
