has anyone done this or can shed any light ? thinking of upgrading while the engines out, would I need to change the lateral 56mm intake to the 76mm aswel ?

thanks in advance

P.S. anyone interested in the MD321T if I go ahead with it ?

 

We are run MDX321T at 490bhp,with better heads we are still think T should make 500bhp on 20% methanol without the problem

MDX321V should be good upgrade,just depends for how much power you are looking.

If you have older non billet T,I would speak to Mark@Lateral Performance or Turbo Dynamics about the upgrading to the Billet,is really worth

How much u want for it, that's the question

 

I'm at 464bhp with just Vpower now and that's a none billet T, I was just thinking about breaking the 500bhp mark while the engine was out and what else would be involved. stil uuming and aahing lol

 

Long time ago now, but I have fitted a V in exchange for a T.

Overlay below.

 

The V then went on to produce this on a 2.1 built by us rather than the 2.5 built by an other.

 

are those results with the billet on both Martyn ? how did the difference feel between the two on the 2.5 ?

 

Pre Billet wheel, as I said, it was a while ago
It felt exactly like what you see on the graph to be fair, bit less at the bottom, but more at the top, it's what happens when you fit a larger turbo.
As it happens, we're swapping a Billet T for a Billet V at the moment on a 2.5 equipped car. Just waiting on it's gearbox rebuild and we can get cracking.

 

keep me posted on how that goes please martyn I'm very interested, what work has been done on the 2.5 block to handle that ?

 

How much for the T?

 

I've got a non billet MD321x which is a V with a smaller exhaust to reduce lag which I could be interested in a swap for a T.

 

According to the graph the T gives more power than the V in most of the rev range.It has about 20bhp more in the midrange and it only looses to the V in the top end.You have to drive the car harder to get the gains from the V.I suspect the T is faster than the V in most of the tasks.I bet even in the quarter mile the T is only a little bit slower than the V though i dont have that much hands on experience as much as Martyn.How does a rotated Sc gt30 billet compares with these on the same or similar spec engine Martyn?Thanks

 

Is that graph not slightly "hooky" Martyn? I understand if the power drops off like that on a DD RR, it's normally down to the car lifting out of the dyno and the rollers trying to catch-up. Obviously this effects the peak figures if that's the case as they normally get inflated under that scenario.

 

In my experience, the Billet GT30 will spool as fast as the V and go on to produce a chunk more power too. Haven't mapped a Billet V yet, so I cannot comment on that one for a week or so.

 

keep me posted on how that goes please martyn I'm very interested, what work has been done on the 2.5 block to handle that ?

 

It's a forged motor, but as for the block itself it is a stock one.
It was a new block when it was built last year after the owners previous motor threw a rod.
We have ran stock block motors to 580bhp in the past and have plenty running around the 500bhp mark without issue.

 

LMFAO, you don't get hooky graphs down here m8.
The drop off was consistent with the drop in boost at the top end, not slipage !
The car ran a 10.82 1/4 mile, so you tell me, is it 500bhp or not ?

 

That must be some drop off in boost!

 

Stop trying to show off Shaun.
Martyn ties them down good and tight and you're talking bollocks.
Let's see what we get out of this latest one, rather than raking over old news shall we?

 

Alan - don't take things so seriously and out of context!! I can see from Martyn's response it was a goood humoured (even if tongue in cheek).... perhaps it's your old age!

My inital comment was asking a question, not making a statement. My 2nd statement was tongue in cheek - you miserable old fart!

 

 

That he is boys, that he is

 

You hold 'im Son, I'll hit 'im..

 

Sounds like Rocky Balboa - the 64yr old version!

 

I'm actually 61.
And we're all just passing through..

 

got a knocking and clicking noise from rear ov my 05 wagon not metallic any ideas thnx

 

Any way lads less of the fighting and abit more of the good old elbow greese and lets gets sum work dne coz im itching to get my car back... lol

 

does anyone know if i would have to change to the 76mm intake hose from the 58mm on the MD321V ? do they suffer alot from surge on that dia ?

 

Yes you would and no it doesn't.

 

cheers
