Turbo specs

[robertisaar]

i didn't see anything related in the whole 5 or 6 threads in the boost section so i thought i'd ask: would there be any problem with this turbo on a 3100 and eventually a 3400:

T3/T4 Hybrid Turbocharger
0.50 A/R Cold Side
0.58 5-Bolt Standard Hot Side
3” Inlet Diameter
2” Outlet Diameter
0.50 Compressor Wheel Trim
0.50 A/R Compressor
0.63 A/R Turbine
57 Trim
Turbine Wheel:
Exducer : 2.48"
Mayor : 2.89"
Compressor Wheel:
Exducer : 2.07"
Mayor : 2.36"
25-35 PSI Peak Power Performance Output Capability
CNC Machined Flanges

or something like this:

T70 Turbocharger
Inlet (Exducer/Hot Side) T-3 Flange
0.84 Exducer A/R
0.70 Compressor A/R
Cooling/Lubrication Oil
Outlet (exducer/hot side) 3 " V-Band
Inlet (compressor/cold side) Ø 102mm (4")
Outlet (compressor/cold side) Ø 65mm (2.5")
Compressor major diameter Ø 84 mm

the first turbo is what ive calcuklated to be about ideal for my 2.8l. it may be just a tad on the small side for a 3100 or 3400. you may want to go with a t3/to4e 60 trim

the 2nd one would be a bit to big.

[robertisaar]

so the small one might overrev and the big one wouldn't make full boost. how would an intercooler effect the small one?

btw, boosted89rs from the fullthrottlev6 forum said this about the "T3/T4":
"the actual specs are t40e .63/50 46 trim and is good for 18 psi on a 3100"

if you want to read all of it

and what exactly are you using to calculate this? i've tried googling for information about turbos but didn't get much out of it

You do realize we are also memebers on many boards? lol.

It's not actually a .46 trim, its even less effecient. I am the one who made the discovery about the fraudulant advertising and could dig up the actual measurements of the compressor wheel. I bought the same one as boosted, dissasembled it, measured it, and had to calculate the actual trim.

Glad to see some more faces in the world of turbos .

Where are you located?

[robertisaar]

ever heard of camden, mi?

turbos seem compicated until you actually see them work, then its like a brick wall. if everybody would see one work, goodbye centrifugal SC and Roots will only be for top fuel

I'm ForcedFirebird or Forced_Firebird at those same sites, except TGO - firstfirebird .

As far as turbos being any better than a S/C could be argued until blue in the face - there are pros and cons to both systems.

A centrifical works alot like a turbo, except with the benifit of almost instant response and can be easily adapted to an intercooler.

To answer your question about the intercooler: Absolutely the turbos you selected will benifit from an intercooler. If you plan on pushing any significant amount of air into the motor (more than 5-6psi), you are going to need to cool the charge enough to run on pump gas. You have to remember the compression of gasses is going to cause heat which is a major enemy when taking detonation into consideration.

Garrett 60 trim left..cheap ebay one right..ebay one isnt going back on for the new setup im doing..both are t3/t4

[IsaacHayes]

hey loner are those kumho AST tires? That ebay turbo does look a lot smaller than the garret.

Again, the ebay turbos do not have the trim as advertised. That ebay is probably a .46 or even a .40 trim (the less efficient, the cheaper ).

[robertisaar]

i'm sure it is less efficient but i'm not looking to build a 600hp motor, but when it comes to a 3100: turbo, centrifugal or nitrous are about our only options for getting our underpowered motors to do anything.

The problem with a less efficient turbo is that you are actually pushing less air. boostedrs had good results with the xs power turbo, but actually maxed it out. Had he changed it for a real .57 trim , I believe he might have gotten more out of his set up.

If you can spring the dough, look into the Gt series from Garrett. I have seen an article where nothing was changed on the car except for going from a t3/t4 hybrid to a GT hybrid and results were shocking.

i'm just looking to start small, and when its ready to be upgraded i'll stick it on a fuel injected, 60* dune buggy project. and i don't have the money to be sticking a garrett turbo on my car, but i do have enough to buy a cheap, inefficient turbo that'll get the job done that i want it to do.

That's the attitude I had . Got my parts for around $1000 and did it in my driveway...

Here's a pictoral of most of the install...
