2.0 CR big turbo build, aiming to set WR

This one is too small i think for that boost Ruben.
I dont know the dimensions of the wheels yet.
I was thinking of the 65mm cw gen2 (gtx style) and a TW between 4650 and 4951 , somewhere in the middle.

The big vklr did 3bar boost , 2.9@ 5200rpm 130mg of fuel, clean as Euro 6 , no smoke whatsoever. But couldnt live with it ..various problems.

Buy my turbo Mac

I have good turbo J, dont need to spend on something i dont need Asking too much money on that unit imo.

Last test yesterday with new settings:
1 bar 2200
2 bar 2760
2.58bar 3050rpm

Starting to look right i think.

That kind of small turbo with 16v, i think it should spool much faster.

surge limited if you use a cw that does 400hp with emp near boost =)

Depends. one could go to other and buy a turbo that is promised to work but leaks oil, go to some other company and get the same. In the end u have spend double and still only have leaking turbos. Therefore if you can get a tested unit I think its worth to go for that.



Ive been through more leaking turbos with the td05 wheel then I have fingers on a hand :/

Yes i remember he spent money but my car is on sale now so no point investing more money.
As soon as i do my 10s run 100-200 i will be pleased with the result , should be a good indicator of performance and i will consider it done.

Thats why i went to journal bearings because its more solid, no oil issues either.

Ruben you think it could spool better? Tbh i am so pleased with how it goes now, car drives nice finally.

I think youll soon end up w surge in higher gears. What cw u use?

I think £1750 for a nearly new turbo with a Darkside manifold is very good.

The turbo alone cost far in excess of that to have built.

Trust me as Ruben said you often get issues with oil leaks etc.
This turbo had been on and off two or three times due to a variety of issues from a variety of turbo builders and only after considerable cost to myself and Bobby in both time and money was it working well.



To get an equivalent spec from Darkside it's £2200 with VAT
Plus the manifold which Darksides one costs £870 with VAT.
Of course you can get cheaper manifolds etc.


Included speed sensor and all the associated wiring and connectors to OEM loom (this was another £150)

including water line adaptor etc £75

So from Darkside, it's realistically going to be £3000+
Nearly half price for a unit proven to be leak free, fully balanced with water lines and all other sensors etc and produce 400hp is good value.

Who is ****** enough to pay 2200 for a turbo from DS? LOL their prices are absurd.
AVD makes it for half the price and it did not have oil on the exhaust either.

Unfortunately this is not stuff you sell easy J.

To be back OT, today i do another test.

How’s those b8 injectors going? You out of fuel yet? I’m looking for some nozzles

Going well. Injectors were never a problem.
The tune could be better for sure, but it is what it is.
There are some aspects that need further improvement to go really strong.

I have made some modifications to the software lately, still far from how i would like it. 20 versions were bad or no improvement, 1-2 were ok.
Thanks to Hannu for advices! and for supporting me.

Tomorrow im gonna start working on a new bigger turbo.

New turbo finished, i tried to set it as best as i could and seems to work nice without touching the software. No oil on exhaust , no smoke. So for me its better than the vklr i tested before.

This turbo has done 435hp on 2.0 PD, so i am confident it can deliver the long awaited result.
Have to do 2 more upgrades on fueling and i am really done with this.

I'm happy with how it spools, and a good tuner will make it even better

PS. chinese gauge reads 150mbar less than real, and its slow

Good .

Did a few runs today, not much has changed
Gearbox shifting is pretty sh:t and slows me down a lot

Went today to the most accurate dyno we have around here, heart breaker how they call it because it measures lower than the rest. Measured in 6th gear. It should be better ..but it is what it is and thats fine with me.



I have a few upgrades planned and we push for more. The 100-200 will be measured soon also. For now i am done with it.

Max torque at over 4000rpm. Really??

on the street it looks like this, car moves very well as it loads much better , 500nm from 3100rpm

Nice! Congrats! What was the weight of the car?

with 85kg driver and full tank it measured 1528kg. It has much heavier dq500 gearbox, big brakes, meth tank+pump, nothing removed from the car

100-190 acceleration is 10.45s then gear changes and 100-200 time suffers
