All you guys whos using to4B 60-1 with your 2nd gen what kind of rwhp figures do you have and with what mods? Iīve asked how much rwhp can be made at 14psi with street ported engine and what have come up to is 280-400rwhp!!?? I donīt know what to believe anymore so iīd like to hear the truth from who actually is using this turbo and knows exactly how much itīs goos for.

I donīt wanna hear " I know this one guy who had that turbo a few years ago and he made..." BS!!

Only facts needed.
Thanks

 

Not sure. I will be installing mine. TO4B 60-1 .96A/R .70Trim 4"inlet. Haltech, Parrallel fuel system etc etc.

So once its dynoed I will post pics. It will be some time yet thought.

Also I intend to log my boost so that people will have something to see. I was interested to see how well this will boost.

I thought generally you would see around 400rwhp @ 15psi.

 

The reason you get such a variance in HP figures, is that there are many factors that come into play, other than the turbo compressor (60-1).

-Turbine A/R
-Engine Porting
-Manifold design
-Tuning
-Type of Dyno

 

Get real...
There are too many variables to quote you a single number.

eViLRotor is right.
The guy with the NOS shot can easily attain 500+, but he's still running the same turbo.

Why don't you do a search and do some research before demanding such info?

do a search, you'll turn up lots, but heres a reference for you.

Jspec stock motor
60-1, .96 hot side undivided
HKS undivided cast manifold
HKS 40mm wastegate
3" turbo back to Apexi N1 Duals
Custom Spearco FMIC with 2.5" Mandrel Pipes

Running 1 Bar on 93 pump gas, @ 10:1 a/f with conservative timing on a Dynojet put down 381 rwhp and 317 ft/lbs

 

Hey faster, I have a S5 To4 60-1 hybrid on my S4 TII. I put down 298rwhp on the stock motor (mazda reman, w/29K) and 256tq at 10psi. I have a 2.5" Dp/mp (silencer) and the N1 catback. Walbro pump, S-afcII, 680 & 720 injectors. Custom 3" TID and a S5 IC. I was running pretty lean though, all through the 12's on the A/F and sneeked in to the 13's a bit. So, I guess I need more fuel still.
