I made my first run at the street with all my mods installed a few days ago.
I made a power-measurement with my Blitz Power Meter (I know.. it probably isn't very accurate...), just to see what I got.
It shows that I'm getting about 290hp.. Could this be right? 290 at the flywheel or at the wheels?
I'm running 10psi on at stock engine (rebuilt last year) and stock seq turbos.
My performance mods. are:
-PFC
-Apex'i Cat-back
-HKS Downpipe
-GReddy 2row FMIC
-GReddy Airinx Intake
-Full Unorthodox Pulley set

(My PFC is not tuned by the way..)

dubulup

sounds right (close) to me...the at the wheels.

tune that pfc.

With the mods in my sig on a stock motor with 84k I got 255 at the wheels. yours sounds close for hp at the crank.

What's your PFC say as far as boost? Sometimes the Autometer gauges can be off by 1-2 psi. 290RWHP feels more like 12-13 psi. It's probably reading at the flywheel.

dubulup

at 10 psi I was making 280rwhp with stock IC, and similar mods, except I run the PFS purple box...a/f 11.7

I do not have the PFC Commander yet, so I don't really know the PFC-readings. My GReddy gauge shows about 10psi.
Would it be okay for me to turn boost up to about 13psi when I get my new injectors and fuelpump?
Seems I have to tune the PFC myself..
No rotary-tuners for hundreds of miles....

dubulup

You should be able to run 13 psi with stock fuel set-up.

I tuned for 12psi (pri) and 13psi (sec) with the stock fuel set-up and made 301rwp. Injector Duty cycle under 85% too.

With intake, dp, cb, hiflo cat, pfc and stock IC I got 290 at the wheels at 11 psi. Chris at RP said mine was pretty typical actually I think he said it was pretty good so yours sounds about right.

ttb

probably at the fly wheel, unless you got a really healthy FD.

SPOautos

It sounds spot on for your mods. With those same mods and a mp added in I ran 12.3 @ 113 which is around 330rwhp. If you throw on a mp your going to be very suprised....its going to provide HUGE seat in the power.

I've been thinking about getting a downpipe, but heard a lot of different opinions about it.
Is it really safe? Won't the lack of back-pressure create problems?
When I think about it.. There will be no back-pressure at all! Will there?
I hope someone can talk me into getting a midpipe!

SPOautos

Yes there is huge back pressure from the turbos. The more you open your exhaust the more power your going to make. Turbo cars do NOT want backpressure from the exhaust. All that does it choak the flow and make the engine have to push the exhaust out harder.

A midpipe will make a big diff in your car.

BTW, you last post said downpipe but your main post said you already have a dp.....didnt you mean you were thinking of getting a mp (midpipe)

When I used to have similar mods, I put down 291rwhp with intake, exhaust, ecu, dp, and also a SMIC

1FooknTiteFD

oh yeah, and i did it on the dyno too, so maybe your power meter is pretty accurate? You should try putting your car on the dyno to see

Tomco78

Sorry! I meant Midpipe in my previous post!
I'm gonna have to wait to the summer with the dyno, the nearest one is quite a bit away!
Guess I'm gonna have to try to tune my PFC in the near future, never done something like it before....
