I'm new to this turbo stuff, but after finding a T04B for free from a friend I thought I would get on here and do some searching. I found alot of info, but didn't see anything on an air research .80. Plus theres alot of posts about a 60-1? What do I have? Any info would be great! Thanks

 

measure the diameter of the inlet compressor and compare it to this chart

http://64.225.76.178/catalog/comp_wheels.html

That is the only way I could find to determine the "trim" of the wheel. The I found a compressor map for the compressor that I have (go to the knowledge base at the top of the screen and learn to read them) and found out that the T04B that I have would be great on a little V6, or as half of a twin turbo setup for my 306 Serves me right for not researching throughly before hand (in my weak ass defense, I was having trouble getting good numbers on the turbo before it was in my hand. I know, weak like I said)

 

ok the first question would be what is the inlet compressor? Sorry but i'm totally new to this turbo stuff.

 

the little wheel circled in red, measure the wheel not the hole/opening.

Hey I'm a noob too, somebody jump in if I'm wrong here!

#ad

 

ok, anyone else have any more info?

 

careful, they don't like us noobs around here... did you learn the bit about reading compressor maps? (from the knowledge base) That will tell you if it will feed your engine or not...

https://www.theturboforums.com/content/113-knowledge-base#compressormaps

most of the maps are listed there, and underneath that there is a section on how to calculate "how much" compressor you need.

 

yeah I read all that. Just didn't know how much that turbo will put out. Thanks!

 

I guess I need to know which one I have: T04B S-3, T04B v1/v2, or T04B H-3, etc.. Sorry Im slowly learning

 

Ship that thing over to me and stop worrying about it

 

TO4B STANDARD SHAFT
S 1.904"
SUPER-S 1.904"
T5/6 2.032"
V 2.180"
SUPER-V 2.180"
H 2.298"
SUPER-H 2.298"
60-1 HI-FI 2.324"
60-1 2.324"
62-1 2.441"

that is from one of the links I posted above. If you have a 2.180" compressor inlet, you have a V trim, etc. Then you can pick the right map, and see if it meets your flow requirements. IF it's for a 302 or bigger, I think your screwed unless its a V trim or bigger (ok not screwed if it was a free turbo )

 

yeah send it to me so I can have a useable pair... I have one T04B and it's not going to do jack for me

 

Don't shoot me down, but all the ones I've read about are a/r .60. Mine says .80. Does that tell you anything?

 

doh... that was a turbonetics web site that I posted... I guess air research might have different compressors. Maybe you can find a page like the one I posted, but for air research instead of turbonetics. Sorry about that.

 

You guys can speculate all you want, there are only six little bolts holding the comprressor cover on, so pull it off and do some measuring already!

 

T40B!

The T4OB you have will work on a 302, it will be fine at lower rpms, but after about 4k then the turbo will be the restriction. It doesn't mean you won't make power, it just means you wont make ungodly power.... I think this combined with a B&G single setup would be a good starter system. For a twin system, it would be stepping up to the big-boy league. Enough power to split a stock block, EASILY....
Anyways, good luck...noob!

Re: T40B!

lol...

 

Re: T40B!

STOP all the bad tech already!!!!

They are the same.

A S-3 or V-1 or H-3 are the same compressors, no matter who makes (copies) them.

Dude, How can you say a blanket statement like that!!!!!
You don't even know what trim he has!! Or turbine wheel, etc. etc.

A V-1 or H-3 is PLENTY big enough as a single on a 302!
Good to over 450 HP.... If you need more than that (on a single) you could start at T64 or so. Turbo shops do upgrades pretty cost effectively.

Having said that, just by "eyeballing" that picture, that wheel looks like a S-3 or a T5/6 trim compressor. Both are too small as a single on a 302.
It is also a very commonm "Diesel" engine turbo, and probably has an exhaust side much larger than the compressor (for gas engine applications) and also even looks like it has a "weird" T-3 inlet flanged turbine housing.

I hope you got it for free, because it is a good parts turbo. Not really usable as it is.

 

Re: Re: T40B!

Humm, so you're saying I didn't look at the picture and think to my self, Gee it looks like a T5-T6 trim compressor ...which would be too small for his application....

-bix

 

You didn't say why....you just said it would be too small, without any actual facts.

And you have it wrong, it's called T5/6 trim, not T5-T6 trim.

And I don't think your eyes are so good to tell the difference between:
1.904", 2.032", and 2.180"

 

Any bets before I let you guys know what it is?
