At long last I will be taking the '99 NB to the dyno tomorrow. I'll be using the Dyno Dynamics Dynamometer (load bearing, eddy current) located at Henderson Performance in New Braunfels. Cory, the dyno owner, will be operating the dyno, and representatives from BEGI will be present to assist with tuning. I'll be driving WARI to adjust the Adaptronic maps.

The goal is 300+ RWHP, but above all to make it a strong, non-marginal tune on 93 oct pump gas. We will tune for MBT and knock onset (whichever comes first) without the water injection, then back off a couple of degrees. Then I will add the water injection on top of that for additional margin. This is a daily driver so the goal is fast but reliable.

INNNNNNNNNNNNNNNNNNNNNNNNNN

for results

OMG I'm getting antsy already

 

11.5:1 afr, conservative spark considering you have 180* pickups. You also want 11.5:1 on enrichment. If anyone disagrees with you, they're wrong.

 

Agreed, thanks. I am shooting for 11:1 - 11.5:1 especially at higher boost levels, say above 10 psi. Considering the monster injector size that should be easy to do. I am not going super aggressive/marginal extract-that-last-2%-of-power on the spark table. I do not want to risk knock if there is a WI failure. I am making this very clear up front. This is a South Texas DD, not a dyno queen.

Trey are you going to be in the area? You should drop by.

 

Sweet, I'd be interested with the numbers!

 

IN for results. Sounds sweet.

 

Nice! Definitely 300+

 

I'm either crewing for a chumpcar race or going to OKC for flooding party.

 

In for updates!

 

Good luck bro! In for results.

 

Is .030 a tight enough plug gap?

 

.030 should be fine with COPs.

It's about time we see some results from your awesome build! I've had a personal interest in how this will do.

I'm interested in seeing what happens with the .64 A/R on the hotside.

Good luck!

 

So far 0.030" has been fine. No blowout up to 18 psi with the COPs. If it does I'll regap them, only takes a few minutes, although the plugs will be hot

 

Nice!! In for results mang.

 

You're gonna like it!

K so where's these numbers?

 

 

Hey man, my buddy has a truck if you got stranded.

 

I'll cut to the chase
~290 RWHP @ 18psi. Corrected only for altitude, added about 10 HP. I guesstimate ~340BHP. This is on a Dyno Dynamics dyno, so presumably it would read higher on a Dynojet. Water injection is off.



This is with conservative timing, about 14 degs advanced @ 18 psi. There is a lot more there with more boost and timing but I like my engine, trans, and diff in their current state. It's pretty quick, spins the tires in third @ 50 mph.

EDIT: Forgot to mention the AFR was 11.5:1.

 

******* awesome.

230ish WTQ at 4K RPM, and it does'nt drop velow that until about redline, Peak is what 255 or so?

On a dead-safe tune that you can drive like you stole it every damn day.

Nice.
