i was thinking of getting rid of my 60-1 it's brand new and i got it a awicked price!! but i am setting new goals and in the market for a fd now..but some people are saying to4r over the to4s why i don't know why, because i have a dyno sheet with a to4r compaired to a to4s the to4s is making better power and faster! what do you think? i think the to4s would be better..any input..any help plz as i can get a to4s right now for a great price..

T04S = 60-1

T04R will flow more air.

 

yes i realize it's a 60-1 now but ok whats the main difference than? between the to4r and to4s?

 

Dude you've got a freakin 3 rotor in the dyno comparison.

....keep your turbo.

 

i know i clicked on the 3rotor one by mistake to graph but the one above that has a to4r and is a 13b...and he is making 472hp i think it was at 19psi where the to4s is making well over 500hp at 21 psi i know 3 psi difference..but big difference and i know the are different..maybe i should call steve at gotham racing tomorrow?

here are better dyno's to compare 2 to4r and sum to4s turbo's?

to4s also same as my turbo (60-1) but may have smaller wheel and mine is a q trim
Exhaust A/R 1.15
Compressor A/R .7
21psi

to4r
exhaust A/R 1.00
compressor A/R ?
19psi

 

T04R:
66.7mm comp. wheel inducer
84.0mm comp. wheel exducer

T04S:
59.0mm comp. wheel inducer
76.2mm comp. wheel exducer

Both use the same compressor housing, which is a T04S housing (unless you have a 60-1 HiFi, which uses a standard T04B comp. housing).

Anything past 15psi, the T04R should and will outflow the T04S. Supra guys using the T04R see boost levels up near 30psi, and are still making good horsepower numbers. The T04S, on the other hand, begins losing efficiency a little before 20psi. You would probably see better number than most using a Q-trim turbine wheel on the T04S, but your turbo response may be a bit slower.

 

god damn double post

 

Hmmm maybe my T04R info is wrong... my thought was that a T04R was a 62-1 in the same way that a T04S is a 60-1....

Either way, the thing I type into the dyno webpage is what the turbo OWNER says... (in other words, I don't translate "oh this guy says T04R, I think that is a 62-1, so that's what I'll put)

 

Looked up some specs on the web... here's what I found for some turbo compressors...

Name - exducer(inches) - inducer(inches) - exducer(mm) - inducer(mm)

60-1 3.000 2.324 76.2 59.0
62-1 3.000 2.441 76.2 62.0
HKS T04R 3.307 2.626 84 66.7

 

I'd like to see what a Q trim, 1.15, 60-1 setup will do

 

Me too... Also would be interested in seeing a datalog of a 3rd or 4th gear run or something.

BTW, lol... looks like you answered your own question about the 62-1 and the T04R deal

 

ya..thanks...i will try this turbo first if it doesn't gimmie the numbers i want i will upgrade
