Turbo Sizing

[woah4]

Very cool. Obviously alot of things to consider here. I will get on a better catch can set up ASAP! On another note with the turbos, how about holsets, hx35 and the like? I dont see much about them in comparison to gt series garret's, but the price sure is attractive

Zappo (George) AutoX alot and he switched from a 3076 to a GTX2867R because it spools quicker. He's also got forged internals, modified oil pan, m56 w/ lsd, etc.

Correct me if im wrong but didn't jcviggen run a disco potato also? I like that turbo but for the use the car will see, im thinking perhaps a gt30 would be a better choice. more drag and highway time, rather than autox style. If I was going to do autox though, it would be no doubt a gt28. love the turbo, but hate to think I would wish I had gone larger. Thanks for the input though its always appreciated.

And boxpin, that setup looks perfect, would you just use a Y connector to one box and run lines from the dip stick and block instead of having two boxes if you did it again then? My only concern is that in cold weather here, the condensation builds up in my catch can and essentially blocks it (but to be fair it was just a cheap can) so hopefully that would be less of a problem with a better can.

Cheers!

I've gone through any number of iterations of breather setups. This is what I use now - it works.

To deal with the vapors - I tried this:

Then I just plumbed the tertiary can back into the intake tract to capture all the vapors

As long as you have vacuum draw from the intake, you shouldn't see blockage, as the vacuum draw will keep the lines heated.

I tried a vacuum pump over the winter when I was still VTA, it worked, but only draws 1-2inHg

I also tried a Provent, but it doesn't work well with VTA setup

Amazing detailed drawings, you should work in the animation industry!

I was thinking the same! outstanding! I will have to have another look at my car tommarow to grasp the full concept I think, but I see where you are going with it. That should work nicely, but of course the real test will be winter lol

H, you crack me up. I cant tell if your a teacher, concept artist, engineer or Volvo pioneer. Maybe its all 4.

I couldn't get Siemens injectors to idle. AFR's would be all over the place. Bosch injectors, right every time. I think Zappo also had trouble with them, and several UK people ditched TT because they couldn't use Deka/Siemens etc. Since TTusb is just an overlay, I would have assumed the issue is with M4.x.

You didn't have any issues calibrating or idling with them? Are you only running E or do you also run pump gas? Maybe tuning for Ethanol removes the issue, I dunno...

You can run any high impedance injector with M4.4. The problem with Siemens injectors is inherent in TT. A major factor in getting any injector to work correctly is properly adjusting for the latency. Since TT won't let you adjust the base injector latency or the voltage-latency table you wont be able to get any injectors to work that don't have similar characteristics of stock blue injectors.
