Well its been under wraps for some time now but since this is the 3rd car and all show great results Marco said to start sharing the info. The very mention of these products in the DSM world seems to cause so much debate its stupid so at this point I will let the numbers speak for themselves.
It is the new Magnus cast DSM manifold, similar to their evo V5 manifold and all I can say is wow. No other changes to the car except it went from a Q45 throttle body to a 100mm wilson. The manifold its tested against is the Magnus large plenum Drag Manifold.
First pull here is 21-22psi very low timing and very fat, mid 10s on both runs. On these charts however, suprisingly the old numbers are with a 1.01 housing and the new a 1.28 so more power sooner despite the larger turbine housing.
26hp 12tq came on sooner as well. Good start but lets turn up the power
Next graph I had for comparison is a little strange both settled at 38psi but the old manifold somehow spiked to 40psi then settles to 38 hence the high spot when it hit peak boost.
Roughly 70hp gain and again came on sooner. Just for comparison the new manifold made 808hp at 35psi 3 psi less than the old and the same power.
Next runs are 2 graphs that where very close in peak numbers but the new manifold spools sooner, was on its way to more power and the real kicker is the new manifold is at 41psi and the old 43psi.
25 more tq 3 hp 2 less psi and gains as high much as 80hp in the mid range.
We attempted to turn it up to make some 4 digit power but had to shut down due to a IC pipe blowing off and causing issues. It was well on its way to making more power than the car ever made before overlaying it on the previous 1033 hp plot. We will now address the fact I am pushing the limits of the fuel system and go back one last time for some 50psi numbers.
Thanks to National Speed Inc for their help with the dyno time. And what else can I say the manifold outperformed even what I had hoped for it. Anyone can weld 5 tubes together, it takes a lot of design and engineering to make a intake manifold work like a 75 shot.
Congrats Marco! And thanks!
