TO4 Characteristics?
What do you guys think about the T04B? Not the E. Does it make good power? Hold till redline? Spool early? I am interested but I dont know much...thanks

I know someone doing a K26/T04E with .50 a/r hybird.......claimed it would support 500hp.......
I asked about CFM flow numbers.......never replied
ALWAYS ask about the CFM, that is what matters.........if they don't answer, turn your back.........

While running 18psi on a TO4B...would i need to worry about timing retard and such? I ask because i know for 18psi on the K26 you need to be careful because of HG failure or low octane. Is this still a problem with 18+psi on a TO4B? I only ask because it is a larger turbo so lower compressor temps at 18psi....thanks

Hi 9fitty1,
There are quite a few configurations for the TO4B.
I don't know if anyones gonna give or is able to
supply you the right combination info. Might be a
safer bet to go K27/6. Do understand that if you
pick the wrong compressor trim & the wrong AR
for the compressor housing, the performance
could end up in a big disappointment.

In my opinion the To4b turbo isint a real good investment compared to what's out there so unless you are getting it real cheep then I say go with a to4e or s or r. Those are all much better turbo's that make more hp and tackled with the right turbine can spool up the same or even better.
Also it's hard to beat the K27/6 for the money ....this turbo will make plenty of power.
For referrence a to4b with a 6trim might spool up slightly slower than a 26/6 but, prolly about the same as a 26/8. You can't give a clear answer on spool up because there are way too many factor's. So you can't generalize and say one turbo will forsure spool up this way always...it doesn't work that way. It depends on your fuel setup what kind of VE your motor is producing what type of cam you are using what type of ecu you are using....am I making myself clear now?? Tunned properly you can have a to4e which will make more power and flow more cfm than the b and have around the very same spool up characteristics.
In otherwords unless you are getting it dirt cheep ditch the b and go for the e.
Tony might have some maps on hand to help out.

Alright thanks. I am getting the B and have no choice...long story. Supposedly it made close to 400whp at 23psi. That is with maf, exhaust, EBC, wastegate and dannos chips. I was talking about all stock VE, compared with the K26.

23psi would need high gas grade, fuel map etc...........
Why don't you tell us you 'long story'? who knows, we could ending up heling you?

I just put on a B a couple months ago. I got it dirt cheap. I had it upgraded to a lighter stage 3 wheel and 57 trim instead of the 50. This turbo also has the #6 hotside. I'm heading to the dyno on Friday and will let you know the results. I plan to run it at 17 pounds of boost.
