Paging any 6# Powerdyner's with headers
 

How much boost do you see?

I dyno'd today and only saw 4psi max. This seems to low to me for the 6psi pulley and mac headers w/cats. My buddy with no headers sees 7psi at 6k I saw 4. No way should I loose 3psi with just Macs I would think. I suspect I should see 5.5-6

I will be checking for belt slip and leaky connections cause I really think it should be pumping out a little more boost/power.

Only managed 396/395 which to me is pathetic as with the 4.5# pulley and stock manifolds I saw 5.5psi of boost and made 384/385. 12hp from a smaller pulley and headers no es bueno.
