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?

 

 

That's very impressive on a top mount, and with a cat !

 

good figures and a nice shaped curve - lots of mid range punch there

1.5 bar ?

 

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

 

Cheers Duncan - yeah, punchy mid but not 600lb/ft punchy 1.6 bar midrange tailing to 1.5 bar top end

 

Mark did a discount then

 

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

 

AFAIK thats a Hyperflow top mount not Sti ?

 

Correct - Hyperflow TMIC

 

Nice

DunxC

P.S. mine made almost the same figures, well up to 4500 rpm..... checking the thing out before mapping.
