99 BEGi S4
 

This is a 99 10AE equipped with a standard BEGi S4 and Xede. Xede is at default, out of the box settings. IE, super rich (10:1 going to 9.x:1) and super weak timing. Stock midpipe/cat, Racing Beat axle back.
Running wastegate only, no boost controller of any sort, appx 11.5 psi. Pulls taken on a mustang dyno and results are not corrected.
For comparison, other cars that ran today
-96 N/A, 80whp
-1.6 M45 car, 120whp.
-99 MP62, 140whp
-94 FM2L 2560, 170whp
-02 FM2H 2560, 170whp

So I'm pretty happy.

Glowing manifold pictures and video coming soon.

Cant see shit. is that 192 peak? Good numbers I guess for right out of the box.

WOW! Close to 200whp on a Mustang Dyno with the stock mid-cat is sweet. Is the S4 stock with a 2560? The curves look fairly streetable too.

To answer your question Sam, yes, 2560.

Fuckin whicked!!!

i wouldn't run that car in that configuration long. besides melting shit in the engine bay, that heat is building up because there's a problem (clog?) downstream. there's free power in that bitch somewhere!

All of those numbers look very low. Because of the Mustang Dyno?

yeah it appears that their numbers would compare with a dynojet better if you add 20%. so ben's 192 is really more like 230ish.

and another thought on my comment on the glowing mani... it may not be clogged exhaust so much as just the untuned xede. not enough advance or fuel or who knows.

I'm thinking a combination of restriction and tune.

Good #s for that configuration any Ben! I'm sure there's a LOT of power to be had in uncorking the exhaust and dialing in some timing and less fuel!

I agree completely that there's more power to be made, and less torque to be lost over 6200. The stock midpipe isn't helping things. Neither are the default settings in the Xede. As far as the possibility of melting shit, watch Paul's videos of the machine on the dyno. He's not having any issues.

Here is the timing map as provided by BEGi:

This is the actual timing map I run. It's the same in boost, but I have changed all of what I perceive to be vac cells to 0. This eliminated the highly annoying P0300 that would trigger over and over as I would drive.

I wish I had a table with the stock timing map so that I could see actual timing values instead of offset. I also wish I could corelate the y axis airflow values to actual MAP values. To atleast get me started.


This is the fuel map that came from BEGi and has not been touched by me. It's fat everywhere, and richer than 10:1 up top.

Less restrictive exhaust and better ignition are coming, followed by tuning. And perhaps an ECU swap to adaptronic if it's deemed viable.

Sometime I'll figure out how to use this camera and get nice pics. Until then,

The dyno operator told us to expect low numbers. He said that their dyno reads low, even as far as mustang standards go.
Ultimate numbers aren't hugely important though.

started tweaking a little. went back to Bell's base timing map and added just a little in boost. pulled some fuel at idle and in boost. made all the difference in the world.

*assuming that Y value 30 is 100kpa.

btw ben, you can get an OBDII scanner and find out what your timing is on the car side.

With most ferrous metals involved with cars, cherry red is somewhere around 1100F. The EGT is seldom below that when under boost or cruising hard. If that manifold wasn't glowing cherry red, something is bad wrong. It doesn't hurt anything and all nearby components are quite well protected.

damn...that mani scares me...it will crack if it keeps doing that.

The S4 manifold is braced to the motor mount.

my tubular mild steel doesn't glow like that. it glows some at the collector but not nearly that bright. this is at 250 rwhp or so.

y8s - isn't your manifold using far thicker material? Like sched 10 vs. something like 16ga. stainless on the BEGI mani? I wonder if anybody watched mine while it was on the dyno- I know it's 16ga. stainless (or mostly stainless ;) ).
