Whats it like?Please no theorys Just experienced answers.

Turbo Dynamics MD240

Specification

1. 48 trim, 93865S specification TO4E 76mm high flow compressor wheel with 53mm inducer diameter.

2. 0.70 A/R compressor housing with 3 or 4-inch diameter inlet & 2.5 inch compressor discharge for maximum air flow capability.

3. Left hand threat shaft with GT28 series 76 trim ‘low inertia’ Inconel turbine wheel, fitted with a racing ‘Staggered Gap’ total seal ring to stop oil seepage caused by large bore or low backpressure exhaust systems.

4. Modified bearing housing fitted with angular contact twin roller bearing cartridge for maximum thrust load capability and fastest ‘spool time’.

5. Specially modified turbine housing, 0.61 A/R with ported & polished inlet throat.

6. Optional uprated actuators (any pressure) fitted to strengthened welded on aluminium actuator bracket.

7. Compact GT28 bearing housing assembly for optimum water and oil cooling efficiency.

Note. Requires modified oil feed pipe and oil drainpipe. Oil feed adaptor fitting and oil return flange supplied with turbo.

What you can expect for your money

1. Boost pressure starts @ 1,800 - 2,000 R.P.M.

2. Full boost (limited) 2.1 BAR @ 2,800 R.P.M.

3. No drop in power @ 6,700 R.P.M.

4. Increase in torque and horsepower over the TB34 unit through the entire rev range.

5. A conservative 450 BHP potential.

Re-mapping is a must with this unit, as the standard ignition map will not keep up with the fast spool up time of this unit. Performance will vary depending on engine specification such as camshafts etc.

 

didn't porkie have this and the reyland bmw?????????

 

phil how can it be a T38... its not made by garrett :P

 

Jim, neither is a T38 made by garrett.

 

Now got rid of the village idiot,can we have answers please

 

in my ass

but anyway i was under the impression that the MD240 is the only name given to that turbo

 

Jimmy..i aint got a clue...i am just assuming its a T38 or a copy LOL...hence this post to find out more about it.

I got an account with TD and this sounds the idea turbo for me.....but obviously i need advice so i can then totally disregard it and buy it anyway...ROFL.

 

MD240 was fitted to lees car a good 2ish years ago i think... so hardly a copy

 

MD240 is not same as a T38, a T38 uses a T4 compressor and a slighlty smaller ex housing i think.

A MD240 uses a GT series compressor housing which is fookin huge.
Porkie/Dan used to run it on the 3door.

Both surge like fook unless engines specced right.

I know someone with a MD240"R" thats recently had his engine dynod at just over 500bhp...

 

Good turbo, i like it, ive mapped about 8 of em now in both the "R" and Non "R" guises and am actually mapping one tonight as fate would have it..

DO NOT buy it without Air Injectors though.

 

Or it is SURGE city central .

 

porkies old engine...



a t38.....

 

As it happens Simon (SECS) uses the MD-240 on his Es Cos.......great turbo! Actually his version was supplied/built by Universal Turbo's it's the version that was optimised for YB engines, was developed on the SCS Dyno (Harvey Gibb) to try and minimise the surge issues...........The latest version that he has on his car has very little surge (BTW he uses a Greddy boost controller).

 

both nice fooking turbo's

 

Cheers lads.

What the differene between the "R" version and the normal one..and which should i get???

 

depends on what you want. the "r" version gives more bhp. it has also a bigger inlet.

 

So doesthis dramatically increase the lag?

Any specs for the "r" version???

 

i will mail it to you. ok

 

Phil,

Dont worry too much about that.......With either version the rapid spool up and (almost) total lack of lag will astound you! Especially if you are used to a T4 or even e T34/35.........IMO the MD-240 is in another league!

Simon's unit (with Greddy boost cotroller) makes full boost (28 psi) at 2,200 RPM

 

there very nice turbo's.

 

Interesting... ive not seen a YB engine that will take that yet without surge on a 240R....

 

Stu, speak to Simon, the original unit that he had surged quite badly........but I sold him my one (that I purchased from SCS), slightly different spec........It's much better

 

Definately interesting.. il be sure to do that.

 

Just had a chat with TD...hmmmm the "r" version would be best for a reliable 450..rather they pushing the std MD240....as you say Doug a totally different league!!!!...Although the surge issues are a bit worrying...especially with the SECS S8 ECU in which i understand can only do a flat boost curve????

Cheers wimwerf!

 

Phil,

You need to go out in Simon's car........VERY impressive power delivery!

 

Well looking like this is the turbo for me MD240R...retails at £1400 plus VAT BUT fortunately i get a nice discount

 

good for you

 

Phil,

Are you getting the turbo from Universal Turbo's?

 

Get Simon to post his graph and over lay it with Yum360 with a T38, I have also done 1 engine with a Internal gated GT30 this is by far the best unit No surge on either unit on my engines and I am not turning down boost to aviod it, This engine made 480hp and 451ftlb.

Mark

 

Mark...i remember you told me bout this T38...does it boost up as quick???

Doug i use Turbo Dynamics...as i got an account.

 

Mark,

Simon wont post on here anymore

Also, with respect........if you overlay YUM's graph and Simons than you miss the whole point! It's the way that the MD240 spools up and not just about the actual power that it makes.

Simon's car feels more like a 340 -360 BHP EVO 7 (with standard turbo)in terms of power delivery........Does NOT come on boost the usual way that you expect from a Cossie.............if you see what I mean

 

Wish I went for that turbo instead of paying 1200 quid for a shit T4 of danny b that needs 500 quid spent on it

 

Doug when you over lay the Graphs you will see the diff remember both these engines were tested at the same place both on a 300rpm per second power test this is about a 3rd gear roll on,Now you will see which on has the most power and best responce ,
For me there is Only one turbo now for the Cossie engine in the 430 to 480hp region bar none.

Mark

 

OK Phil,

But just make sure that you are getting the version that Harvey (SCS) developed for use on the YB engine.........I know that they spent a LOT of dyno time adjusting the spec/trim to minimise the surge issues......So it's a different turbo to the usual MD240 (AFAIK).

 

So i best check to see if they do a T38

 

Ima you didnt read my post correctly GT30 is the one for me.

Mark

 

I know,just testing to see if you are awake

 

Mark,

Tell me about the GT30...........is it a T4 equivilent (in terms of flow)?

Is the GT30 more or less a direct replacement for T4.........very curious??????

Also, I heard that there is also a roller bearing T4 on the market (newish product)....do you know anything about it?

 

Doug it flow over 50lb min, I am dynoing one in just over 2 weeks should be making over 500hp, I will post this when it is done, Much better than a T4 it is a straight bolt on all you need is a 4 inch inlet pipe.

Mark

 

The fact somthings rollerbearing makes no real noticable difference to the way it spools up, its better, newer, designs of wheels and housings that do that, like in GT series turbos.

"T4" is an incredibly basic term too, theres "T4" that can push 700+bhp (ie HKS T4Z for example)
