I have a Saab intercooler sitting in my garage awaiting installation. Do you know how much boost can it support?

I'm pushing 19psi through it without issues :D


Don't feel like you have to defend yourselves. U guys have very important jobs which we are, and should be, gratefull for! :cheers:
 
I thought everybody would get the sacasm but alas not everybody is as darn funny as me.
I was joking for the record. It was funny.


Thanks for the SAab info.....my rig will be a different animal with a TD05/06 hybrid , IC and MHG.
I'm drooling now that I have a new project to tackle.
 
If your saab intercooler has metal end tanks I would say no problem. I have read many plastic end tanks can rupture/ leak at various pressures and are just generally weaker. It is true of most plastic end tank intercoolers.

The MLS gasket can be had at your local toyotas R us dealer. Short of that im sure Radd or other places can ge them as well. If your pulling your turbo off it would be quite worth it to gasket match your manifold to turbo housing as some can disrupt the flow quite a bit.

Chiropractors are great. Just dont adjust my neck and stroke me out tis all I ask.
 
You guys crack me up, Gerg any idea why he isnt getting high egts with his fuel turned all the way up and that turbo setup?
Magnus you built a tubed runner manifold out of weld els right? I am stoked, keep us informed how the new compressor side works for you, I may be looking to upgrade before I even get this thing in!
 
I did not know that his fuel was maxed out. If it is then changing this compressor and increasing boost will have a minimal increase in performance and that there is most likely an issue with your pump or a reason why its not putting out much fuel. I mistakenly assumed that he maxed his egt with the boost he was running.
Just a bit of advice. If you learn how to shoot a gun, you can take that yoga chick for sure. Well at least at a distance.

It may have been in a different thread but your at 500c max correct magnus? I may be remembering wrong, so thats.. 930f ish it just seems really low. I wouldnt even add a inter cooler... are those egt numbers post or pre turbo?
Also this may not even be answerable but are your mpgs average low or high?

To the original poster as you can see there is no "best turbo" you want performance with dropping reliability and longevity of your engine. you want low end boost, or high end boost, minimal boost, average boost high boost. You decide that yourself then size accordingly.
 
Earlier max boost questions at certain RPM were asked so I thought I'd see where I'm at. Took the Sixty for a drive and got this.

1000RPM- 5psi
2000RPM- 10psi then waste gate takes over.

Thats with a front mount intercooler and I lost count of my fuel turns a long time ago! Doubt its more than a turn though.

EGT's never top 1050 (pre turbo)

TBO363, came on volvo 700s right along with magnus and mine. a few 2.0 but mostely 2.3-2.4 liter gas. I can't find a map for it but it looks like the waste gate is set @7psi. Looks like a good turbo for low end as well if those numbers are true.
 
I really got to stop doing things by memory. I was sitting in the kitchen trying to remember where the tach numbers are in my head and as usual I blew it.
I'm going to stop posting now. :bang:

Above post corrected..... again.
 
Those T3s off of chryslers and volvos and tons of other makes and are all well suited to the 3Bs but are not as effecient as newer generation turbos. Compressor trims are most commonly 50 and 60 trim which can map high 20lbs boost easily to 3000rpm. Less common are the 40 and 45 trim which still map fine for the high teens. Turbine housings are .48 and .63. They are sort of the first massive installment of turbos here domestically in north america that I can find info on. They are old... as in early 80s old.
