Default MD321H power run - a comfortable 410bhp

Been a few threads on here about the MD321H turbo recently, so thought I'd post the results of my recent dyno run, which was done at Zen Performance last Thursday. The car has always felt 'quick' on the road, so it was good to see some figures - 409.8bhp and 362lb/ft of torque.



I do use 10% methanol, but what was encouraging was that this car has standard internals, runs a sports cat and has a TMIC - not a FMIC. Also, Zen's rollers are renowned for giving quite conservative figures, so all in all this suggests that (with the right supporting mods) this is a cracking little turbo for a 2L


PS - can someone advise how to make the graph appear in this thread itself?

Cheers Mark and thanks for sorting the image

PS - I don't think I'll need to use that oil feed pipe you sent me, so I'll call you to get that £500 back

What supporting mods are you running mate?

I am fitting the following to my uk STI8:
  • MD321H turbo
  • Samco turbo inlet hose
  • Lateral Performance 650cc injectors
  • Hybrid FMIC & induction kit behind bumper
  • Kakumei Wrapped GT spec headers
  • Kakumei 3" Turbo back exhaust
  • Apexi AVCR
  • Walbro fuel pump

I hope it runs aswell as yours

That's nothing, wait until you see the re-stocking charge
