My 330d Current and future plans*** update page 12 ***

[RAArmstrong]

Burgy from PSR hooked me up with an N54 135i intercooler which will go in next week sometime



:rollsmile:

oooooh interested to see this...
Well done lad.... that car is strong.... Smokey Smokey too:fencelook:

after the manifold was changed she doesnt smoke that much anymore :bangdesk:

Put the old manifold back

More torque? have you forgotten how much torque your car makes?

Your rear tyres definitely didn't forget though. ..

Lol the torque is a bi product of the intercooler. It’s like doing a decat, you benefit from better fuel consumption but somehow end up with more power :fencelook:

Nice stuff nikki

Unfortunately not got back on Tuesday :thumbdo:

Give us a quick review of the falkens on the rear. Are they holding up to the torque being put down?

just a suggestion regarding the cast manifold as replacement for the stainless manifold..

i theorized that the cast manifold was sized and port sizes chosen specifically to supply exhaust at sufficient velocity to get the older design gt2256v as fitted to the 135kw 330d up to speed quickly..
the newer design gt2260v has a more efficient turbine, thus the manifold can be less restrictive and still keep velocity up to get the turbine up to speed quickly.. third generation turbo's as fitted to the e90 330d's have an even less restrictive exhaust manifold because af an even better designed fullback turbine.. here they are for comparison, gen 1,2 and 3 from left to right..



anyways, long story short, i matched the size of the outlet on the cast manifold to close to the stainless manifold outlet to minimize power loss with the bit more restrictive cast manifold.. might be worth the effort if you ever take the cast manifold off again for whatever reason..

and this is why you are the diesel genius:rollsmile:

I wonder if exhaust port flowing the e90 manifold will help with spool on the stock electric turbo.

well diesel fan is fitting an E90 turbo and manifold might as well get him to try it :fencelook:

 

[anton-sa]

the 530d e39 makes 410nm and 142kw... while the e46 does 390nm and 135kw... wheres 6kw and 20nm come from?

 

[DieselFan]

I was going to use an e90 turbo and take the mani on loan as the turbo sits to the side and not in the middle. But the prelci e90 uses the gt2260v but operates electronically whether there are differences within this. I don't know. But my prefered upgrade would be an lci e90 as that uses a gtb2260v.

With that being said. They are hard to find. So i think I might just get a gt2260v which is vacuum actuated from stock. Which saves the trouble of finding and arm which is suitable for the turbo actautor with vacuum diaphragm.

But anyway I think what andy is saying is he wonders if porting the mani. Which from what I understand is shaving some of the metal off will give higher flow. I think it might. But the inlets and outlets are still the same so will it really?

Maybe if it was ported and polished and if the inner of the mani was very smooth. Then yes the gasses would flow out better.

Waiting for the falkens review.
Thanks

Software.

 

[DieselFan]

Hmmm I also thought so. But what had me confused is that racechip claims higher figures for the e39 than the e46. So it makes me wonder if it's just software or if it is indeed software and a remap would take you to the same power

Alex the Falkens are awesome, they were abosolutely shit on the first 2 days with wheel spin in 3rd gear :roflol: but it seems that they have run in now and are more grippy than the conti poes contact 3 :thumbs:

however the facelift E46 330d makes 150kw and 490Nm stock :rollsmile:

Software.

and the difference in power between older and newer generation engines lies not only with more air (better turbo's or multiple turbo's)
but to a large degree with the fuel system.. better atomization of the diesel and more precise delivery means more power.

thats the main reason the 135kw 3liter engine (even with remap) cannot reach the power the 150kw can.. the newer engine has a better management + injectors.

e90 330d can reach more again mainly again because of the injectors.. piezo instead of solenoid triggered injectors.

 

[Andy1GP]

Diesel Yoda has spoken Nico you must grace us with your presence so we can test all the E46 diesels with one another...

 

[anton-sa]

when you start talking different injectors and whatnot things start becomeing expensive. interesting factoid. auto e39's before mid 2000 used injectors that cost over 5k each at agents. auto mid 2000 and on use injector that cost around 3k each. manual e39 early 2000 on use injectors that also cost 3k each.

this is not heresay or a story. i was sitting in the parts dept at autoatlantic and craig there showed me on the system where it describes this and the priceing etc...

can the diesel yoda's explain this ?
