Hey Peter,
We are having a Global Warming snow storm in New Orleans. Go figure.
Everything is shut down so I thought I would contribute.
Probably apples and oranges as far as taking data compared to your system.
Mine from the TFX combustion testing (see attached).
My daily driver set-up:
13B-COSMO (Judge Ito street ported)
peak power @ about 7800rpm
3" exhaust 1 muffler (Racing Beat single)
Cool intake box with 9" K&N.
and either fitted with
T04s or
T04z both use a 1.0 A/R .
9.0:1 compression ratio and about 38 deg C charge temp.
@ 15 boost
T04s 50/50 WM injection (pre turbo and post intercooler).
it made 492 bhp @ 7730 rpm
(15/14.5) = 1.034
1.034 + 1 = 2.034 bar absolute pressure
492 / 2.034 = 242 bhp
Works out to 242 bhp @ engine N/A
at 18 psi and the
T04z 50/50 WM injection and
optimized ignition advance it made
580bhp @ 7854 rpm engine power
(18/14.5) = 1.241
1.241 + 1 = 2.241 bar absolute pressure
580 / 2.241 = 258.8 bhp
Works out to 258.8bhp @ engine N/A
