Hey guys,

Just wrapped up some dyno testing on our E92 MT. Mods include the JB4, BB flash, BMS **, BMS DCI, CPE BOV, CPE IC, and BMS OCC. Factory catback system & midcats. $100 inline fuel pump. Spec clutch w/ steel flywheel.

Fuel for today was E85 mixed with 91 octane. Around E60. Although there is probably a few more HP in there with E70-E80. Dyno room temps were in the low 90s. Fans were pretty good.

The only changes since last time around (461rw) are on the tuning end. More advance, leaner air/fuel ratios, a slightly different VANOS curve, and some boost curve changes when the meth is flowing.

The E85 only runs were on map 7. You'll notice the timing curve was consistently a bit aggressive around 6000rpm. On the two best E85 runs the dyno tach pickup skipped a beat so be sure to look at the torque curve and not just the peak numbers.

With meth I decided to crank the boost up as much as I could. I also left the more aggressive timing curve in place. Basically, I was going for a max effort setup. And the car delivered with 481rw. On the advance to my surprise I found it was still aggressive up top even with meth flowing. This curve is going to need E70 up top + meth I suspect. I'll back it down up there for now.

Anyway, very happy to have the stock turbo dynojet record back in our corner.

Wow!

Terry u genius

well done

If thats what you can do on stock what do u expect from rb upgrade

[GetSomeE92]

Awesome. How much E85?

[steve.kodra]

Very nice! What car and what fuel pump config?

[triggz]

wow what are the specs?

[NJrep335I]

Awesome!!! Now send me the flash and JB4 settings... J/K when your ready.

[Terry @ BMS]

Updated first post with some addl info.

[bmsportzn135i]

So is that a N54 or N55?

[Lifted07Duramax]

Very impressive Terry!!!!

Does this mean you have some new E50, E60 and E70 for us RB guys?

[Terry @ BMS]

We may work up some new RB turbo maps as well. But, other factors come in to play at those power levels. So I'd not be as comfortable pushing the envelope this much with on a stock motor.

Understand, Im still sick!!! Going on day 8!!! Or Id be getting you some of those Map 7 logs on E50. I thought I was going to be able to jump right on it when I got home vacation but that went down the dumps

So with this car putting down 481 is it safe to say the RB guys hitting 20lbs of boost are well over 510?

[Terry @ BMS]

With RBs we consistently make 500-525rw depending on how far they want to push things.

Well when my meth kit gets installed, Id like to go pretty far
While still staying "descently" safe

[GetSomeE92]

That kind of power would shred the automatic transmission in fairly short order, I would assume?

So you are probably in the 520rw range then with RBs.

Only if YOU shred it, Meaning drive around gunning it constantly.
I think it should hold up on the road just fine, now at the track I dunno.

Rob seems to do fine

On the AT for a max effort stock turbo setup at this time we suggest using the map 7 boost curve. Which is good for around 500wtq depending on the fuel/flash loaded. The trans seems to hold up to it as long as you have the trans flash loaded and don't do *too* many 2nd gear dragstrip launches.

[wtfmarine]

What about those of us that can't flash our trans? 2/06 build.

[Terry @ BMS]

Without the trans flash you can run the MT flash maps to get a bit more life out of it at the expense of power post shift. But sooner or later expect to rebuild. When you do, add the new trans module so you can run the trans flash and go back to the AT flash maps..

Would 93 octane and aftermarket mids/catback pushed it much higher?

[NJrep335I]

Terry,

So is this flash posted in the BBFlash thread?

[mykal335xi]

Wow, I never would have thought stockers could push things this high.

+1, I'm wondering how much a full exhaust would add at these power levels, if anything.

Not yet. I want to do some road testing first to ensure it's stable. It's the E85 MT map.

[Cynical]

Anything done to the rear end of this car? Half shafts?
Driveshaft? Seems to be reaching the limit of these parts for MT
