(Typical S4 numbers are crap.) ![Stick Out Tongue](https://rennlist.com/forums/images/smilies/tongue.gif)
(My '81 with a proper (not too big) exhaust puts down more torque than that, and with '79 cams...)
(My well tuned 86.5 puts out the same numbers as a stage 1 85/86.)
What was my point? Oh, yeah... you can get really good numbers out of a 928, just by getting it back to stock tune, plus a little tweaking. Put another way, many of the stage 1 (turbo)superchargers are basically making up for ineffecient exhausts, or bad tuning.
What's with all these SS/chromed pipes, monster turbos, intercoolers stuck everywhere. Cutting the body? Lame.
What I'd like to see is a CHEAP, I mean Walmart cheap, Stage 1 OB rear turbo that can give a well tuned car that extra edge. Stock L/LH2.2 24# injectors. Cheap turbo. No intercooler. Self contained oiling/cooling. Aluminized steel pipes. You wanna upgrade? Get a Stage 2, fool!
Don't make me get out my welder.![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)

And put a muffler on those things...
Gotta be a way to quiet it down a notch or two...
Do that and I'll buy one...

Porken,
The Murf stage 1 S4 is 400rwhp (SAE), the 85/86 will not be far behind (if at all).
Not all stage 1 kits are the same

I know you mentioned Murf's kit before and Tim responded on his thread.
For whatever its worth, a Centrifugal SC is my absolute least favorite way to get boost. Well maybe an olds Roots is worse, but I dont like the centrifugal, dont like the way it looks on the car don't like the way they sound just dont like them. Why, I dont really know, I just want something different.
I'm sure its a great product, but at this point i would prefer something else.

But we'll never know, because Shane is going straight to stage 5, or something.
I'd need only 70ish rwhp for 400. An eRam would do that.

(It clicks here for chart.) STP correction, -7hp, and -10tq for SAE
It's all about the properly sized exhaust.
I think Shane means a muffler after the turbo.

Did that torque peak come from the initial convertor mult. at the start of the run?..the graph seems to show that..but the later peak is only a bit smaller..either way..the S 4.7 motors were torque monsters...stock rated at 267ft-lbs.....

Not sure where..but not much room after obviously...would think one before wouldn't affect it too much..

The stock '81 4.5 was rated at 256 crank torque. (265 is a WSM typo.)
I'm making 277 + 18% = 327 ctq sae, with basic mods.
