Just pondering the idea but haven't seen anyone do it yet. My current set up at sea level should yield around 19# of boost. I only see 15#. Thought I could gather up that extra 4# w/ a lower. Anyone do it yet?
Anyone do lower w/a Whipple yet?

stay tuned...........im putting a 4lb lower on this week. im in the same boat as you. rr 3.0 and seeing 16-17lbs. itll be a while before i get tuned and have results though. im doing a new clutch,headers,mid pipe and some other things. anyway the clutch is going to keep me away from the dyno during break-in period.
*EDIT* sorry wrong thread :rollseyes

I have a 3.2 RR upper and a 2lb lower......I have belt slip bad up top still, My numbers are 603 rwhp and 570 rwtq, I should net around 620 to 630 without any slip. There you go an example of upper / lower combo....I'm at 17psi
3.5 stock upper and old style 4 # lower.
Seeing 15.5 #'s boost

hmm odd, Im running the RR 3.2 upper, stock lower on my whipple and I get 17lbs. was thinking about doing a lower as well, get a tad bit of belt slip.

What idler setup you using?
My setup is a Whipple 3.0 modified to non-slip by Billetflow and a 4lb lower, zero belt slip or wear. Idler pulley is on a Billetflow GEN2 bracket, not using the Whipple idler (selling it actually)

If you're seeing slip, you should think about getting your pulley modified like postban said, or get a RR non slip upper..

I'm using the RR non-slip upper, and I'm using the steeda 100mm idler as seen in the pic. Is there a better belt out there to help prevent belt slip?
