Jess I have seen guys go 500hp with a pdr40 on a dynojet it gets hot though. I would be real careful with a 40 and n2o though. Hx40 shafts are not real strong. I did run a pdr40 a lot, at about 40 lbs of boost with no problems. Stock 40s probably would not take this though. Tim

On my 1996 Dodge CTD I ran 508 H.P. with the Piers HX-40/16. With my 2002
my best dyno run has been 486 H.P. with that same turbo, the TST PM 3 and
high flow (125 HP) injectors. Neither truck really had what I would consider
"high EGT's", as both of them hit about 1400-1450 degrees on the runs. Tim
is right about the boost though. The "stock" HX-40's can't take a steady diet
of boost into the high 40's, low 50's. On both my trucks I had the wastegates
set to about 38-40lbs. and they seem to make good power there and have
excellent durability. Another thing I like about the HX-40/16's is the low-end
response. The lag is very minimal on my automatic and takes off very, very
well. As you saw last year at our dyno day, we were able to see a 12.94
E.T. at the drag strip with cool air.

whats the diffrence between a 40 as a single and a 40 used in a twins package?? I am thinking about doing a 40 and then later on using it as the top turbo for twins. Would I have to make any modifications to the 40 in order to do this??

One thing I had done to my HX-40/16 when I went from the single set-up to
using it on top (at the manifold) in my Scheid Twin Turbo Set-up was to have
the HX-40/16 exhaust housing wastegate "flapper" hole enlarged some.
This helps the HX-40 "bleed off" more exhaust gases than it originally did
and it helps the drive pressure.
