1984 Jetta , TDI WE MUST! (1.9 AHU M-TDI)

Been doing some brain-tanking..



My k03 right now with the 13-15psi I have the manual boost controller set too (according to the squirrel performance turbo calculator) should be producing about 125hp right now.. non-intercooled with no smoke too.. It shouldn't be over spooling the turbine until about 4900-5000RPM. Which I don't think this engine has seen close too in the year it has been in my engine bay.. lol! Working it out on the Gearup.com, the engine has likely never seen above 4300. I have a tach and speedo eventually planned, have had neither for the year its been in! Go by seat of the pants lol.

My updated Squirrell Performance settings spread across the Garrett GT2056, and the Volvo Garrett T3 50 trim.

Similar power points I picked, and some backup on why I did An ALH making that power with mods listed..



Same settings 200hp @ 17.8psi;

GT2056




Volvo T3 50 Trim




As can be seen, they can support 200hp on my setup. The T3 50 Trim does it well, and the GT2056 better than that again. But they are both gonna cost me upwards of $750 ..

let me pop ur bubble: vw is 35 trim.  hahaha




here is the thread that pictures is from, also it is a good thread to see the difference between k24 and t3

That is not what I found through my research.. ?

I found alot of people reference it as a 45? And some a 40.. never a 35 though.

[libbydiesel]

Easy solution, measure.  I just did and came up with 36 trim for the VW T3...  How does your T3 compressor measure, 8v? 

[8v-of-fury]

Ahh goood point Andrew.. I'll look in to it tonight. It's hanging off the back of the 1.6TD parts engine haha.

35 Trim 175 @ 14psi.



The line is not supposed to go down as it goes right.. I am just really jittery right now!

[RabbitJockey]

My post didn't work but yeah I have measured 3 of them they are 35 trim or close enough to be called 35 trim haha.  That's why I like the idea of the hybrids cause they're cheap to build and should e good. the part I think is the most antiquity and kills efficiency is the turbine and wheel and housing.

[RabbitJockey]

See people can be wrong but Rabbitjockey cannot.  I think alot of people get confused because it comes in a .42 at compressor housing, which is the same as saabs and Mercedes and alot of other cars that come with a 45 trim wheel.  But actually u can get any trim t3 in that housing my friend even has a 60 trim in a .42ar

This is vw compressor wheel next to a 45 trim Mercedes wheel which is actually going to be installed on Lucas car

Seems a 50 trim T3 is going to be the most economical bet, for my budget build-up.

6000 is an extreme red line but apparently Chris pulls 6k in his Toaster Oven . Just goes to show it will still be like 67.5% at 6000 rpms pushing a mere SUPER COLD 20psi with the help of the AWIC I will be getting

50 Trim 175hp @ 20.7psi

.42 AR Compressor
.48 AR Turbine

Copy cat

You're the one that put my mind on it.. lol

[libbydiesel]

It looks like you're over the surge line, no? 

[8v-of-fury]

Its right on it, i dunno.. It seems like it could be alright no?

[the4ork]

you can order some of the t3/t4's with a .36a/r turbine as well, and maybe with a stage 3-5 wheel you could still flow enough.

IIRC the .48 hotsides dont start to restrict high HP 16v's until the high rpm range. back from my turbo gasser days, a .63 was a must to break 450whp.

Ive often toyed with the idea of a 45 or 50 trim t3/t4 .36ar and internal wastegate.

[the4ork]

can you order all the GT turbo's without ball bearing?

a 2871 would be cool, provided you can get a turbine a/r small enough?

[8v-of-fury]

This is the one I am looking at;

Internal waste gate
.42 AR Compressor, wheel: exducer: 60.41mm/ inducer: 43.20mm
.48 AR Turbine, wheel: inducer: 62.86mm/ exducer: 45.74mm

(how is that a 50 trim? LOL)
