Latest Dyno and Texas mile build update.
After dumping the E85 fuel and back on gas now, ran down to 98Aggie`s dyno late Saturday night for a chance to try and tune. My larger injectors are not calibrated yet, so getting rich codes and Long term fuel trims are at minus 29-30% now. E85 Alcohol, they were at a perfect minus 3%.
First pull was over 600hp and over 700tq and I was like wow. I did change my tranny fluid out,as it was brown and nasty last week. Hope that helped some.
Based on the dyno pulls now, I would say there is about 25 hp more , tad more on peak TQ and a bunch of average power and TQ up to 4000K to be had still. Once we can find the fuel and tune. Not much time left and to lean to make a pass right now. I have been putting wrenches on the car every day now. Before work, at lunch and will again after work. Upgraded some fuel line and filter but still have inline sensor restrictions to deal with. Will make some test runs later and see if that gets the fuel needed to tune.
Bottom line, car is still out fuel from 4500 up. Had to stop trying to tune, as it wont take fuel changes and running to lean up top. Loosing power over it too. Very rich from 2k to 4K, so a lot of low to mid range power to gain yet. About 50 hp down low on the average. As you can see, engine makes good power to 6500 rpm and that is like 90-100 hp over the stock heads up top. Torque is through the roof and you can feel it hit hard on the dyno! Those long boggy sounding 3rd gear pulls of 550/620tq hp/tq are waaaay GONE now. The car drives smooth, quiet and luxurious at normal driving but damn turns into a raptor beast at WOT!

Better the fluid look brown vs. gray. 
Awesome numbers, I believe the W211 E is limited to 186mph when it is adjusted via STAR, thinking you might break that barrier if allowed.

All tuners know how to blow out the max speed limit.
Shoot Bro MAKE SURE THE TUNERS HAVEN'T FORGOT THAT now that I think about it. Imagine all this time and money and they forgot to blowout the 186!!!
Great reminder!!!

Made a few second gear pulls to check larger fuel filter and couple of the line upgrades, so far so good. Was in the high 10`s to mid 11`s from 2800-6700 rpm.. On the 3rd pull, must have hit the tranny TQ limitor, as the tranny went into limp mode from a 2800 stab. Now that is going to suck for hard launches. Add a little power and so many little things to adjust.
Have to do some 3rd gear pulls tuesday and really load up the fuel system.

The car drives smooth, quiet and luxurious at normal driving but damn turns into a raptor beast at WOT! ) Isn't the 718+ tq a Torque Spike? As it only appears at begining of graph for a blip @ 2500-2600 rpms then goes down to 600-650 rwtq thru the remainder of peak TQ before drops back below 600 rwtq @ 5300 rpm's? Did these runs include the lighter brake rotors & 200mm pulley yet? Great ambitious upgrades & nothing but good luck going out to you for up coming MILE event!

I noticed the same thing regarding peek torque numbers.
I think that blip should be where the torque begins its downward decent.
With some good down low tuning, that torque spike should hold between 2500-4700 rpms.
Hope EC chimes in to confirm or correct my theory.

I didn't want to rain on anyones parade when I saw that super high torque spike but I have always seen things like that to be caused from the torque converter not locking up causing that false increased torque reading. And then the car actually showing what it made after the fact which is more like 635-640wtq not 720. You can find plenty of other dynos showing the same thing and then an explanation of why it has the brief spike like that in an automatic transmission car.
This car still has to be ridiculously fast, cant wait to see a 1/4 mile visit.

Nice numbers!!! what the heck kind of dyno is that though? didnt you post 674whp not to long ago? was that with the bigger pulley or a fluke in the dyno and what correction factors did you use? sae,std or uncorrected.
If this is CF 1.0 then you have one hell of a beast!!!

Spike is not the correct word and no converter will lock up at 2500 rpm on the stab in. Now that the car is making 600 hp, the extra power is flashing the converter harder , when the pedal hits the floor. In a sense , it is multiplying the converter more or increasing the TQ multiple some. So that is a true TQ flash and will show up at launch, if tires hold. It is on all my dynos these days and is not a freak spike. It is very common with automatic cars that make decent power. My other cars with high stalls , would create initial high TQ curves like this as well.
come on, haven`t any of you dynoed high power autos or seen stall converters flash on the dyno before? It is a good thing and a true number. You can flat out feel this TQ all day long. You stay stuck hard to the seat all they way until the gas is let off. I shifted at 6700 rpm and it was pulling the same as 5000K rpm. I think it is time for a 1/4 mile track rental in H town!!
I have to thank URNext (sal) for hooking me up with a killer drag pack!! First class dude all the way! Can`t wait to try it out !!
BTW, my pulley runs smooth as can be and has about 400 hard miles on it now.

I had one updated flash before the dyno last saturday to set a new baseline. I also have new larger injectors VS the 607/674 dyno. I was in the 9 AFR range down low on the 674 TQ (it also had the TQ converter flash in it) , so a little leaner down low and TQ exploded! Changed tranny fluid and fixed intercooler flow problem from before . Little things but they all add up.
EDIT:
Ricker, Do not have rear lighter rotors on but do have the front light rotors on. I know what you are thinking but light wheels dont seem to help on mustang dynos like they do on dynojets.
I did not air up the rear tires or any other tricks. I try to always repeat what I have done in the past, so the dyno can help me learn or adjust to the mods. Yes, I have a larger pulley on but my boost is still under 15 psi with the ported heads and large exhaust. I do not have heat issues either . Last; SAE correction never does help our boosted engines. Me and other 55`s always make better dyno pulls on cool, high baro, low hum. days. Yes the correction works against you but we can stuff more air in the chambers to make up for it then.
My first dyno numbers a few years ago were like 469 hp as I recall on this dyno. I had a 180mm, 80TB and tune as I recall. So , as many know, I have worked my way up the power chain slow and steady. I use the same dyno and same operator.

Yes, I did. Same dyno I have been using for 3.5 years now. LSXdyno tuning by 98Aggie. It is a Mustang dyno and as lways SAE corrected. CF factor depends on the weather at the moment. Each run , weather is checked and CF changed if need be. It was around 90 deg, raining (so 100% hum) and a 29.xx baro as I recall. So CF was near 1 for that day.

Point is unsprung weight should benefit you on DD/MD, but not anymore than 20-25 rwhp/tq I ONLY asked about rotors again cause I figured you still had that much left on table in addition to a full proper tune
I'm obviously NOT an expert nor trying to rain on your tq parade, in studying your graph your rwhp is indeed accurate inmop as it too shows the spike early in graph but continues to eclipse spike & exceed it greatly, while your rwtq reading never recovers the 718+ reading but actually stays well under it thru remainder of rpm band ie back to 600-640 ish. I can ONLY compare this annomaly to the 100's of other dyno's I've seen like it, if NOT a spike/flash it recovers those peak #s thru out rest of run idk? Still exceptionally stout vehicle you've created & yes a 1/4 run in 10's @ 130 mph trap would prove it's as you describe.
Again wish you best of luck all this work from a stand up member deserves to break some records!

I hear but not the case on these pulls. 20-30 lbs plus or minus, does not make any noticable HP changes on the dyno I use. Maybe if you had a few hundred lbs of bodies in the trunk, but that would hurt numbers.
When a converter is shocked under enough power, it can flash and give a TQ peak, until the couplings catch up (if that is correct terminology) . As mentioned, my tune is in the 9afr range down low right now, so the flooding of fuel adds drop the TQ curve early. That will come up with tuning but the initial Converter flash will be there at this power range. The stock converter starts to flash hard at about 670 TQ it seems. My TQ curve at 9afr is following my old dyno graph of 550hp/630tq at first, but it was with a 12 AFR early. So , once tuned the TQ average should come up in the low RPM range. The whole graph will be smoother, as this motor is still not tuned. The shakey lined down low are from being way to rich and the shakey lines up top are from being on the lean side and having some rich dips mixed in. Overall, the motor eats up the dips and maintains decent power.
At this power, this car is not going to run 190 mph. So this power range is short of what I would like to do. Power is good and a lot of fun but again want 190 mph.I know it is hard to understand but just to go 10 measly mph more takes that much more power. From 190 to 200, it takes another 200 hp or so. The cars that run 240 mph, make 1500 hp. Really need 670 hp or so or about 120-0 hp more than when I ran the 180 mph.

I hear but not the case on these pulls. 20-30 lbs plus or minus, does not make any noticable HP changes on the dyno I use. Maybe if you had a few hundred lbs of bodies in the trunk, but that would hurt numbers.
When a converter is shocked under enough power, it can flash and give a TQ peak, until the couplings catch up (if that is correct terminology) . As mentioned, my tune is in the 9afr range down low right now, so the flooding of fuel adds drop the TQ curve early. That will come up with tuning but the initial Converter flash will be there at this power range. The stock converter starts to flash hard at about 670 TQ it seems. My TQ curve at 9afr is following my old dyno graph of 550hp/630tq at first, but it was with a 12 AFR early. So , once tuned the TQ average should come up in the low RPM range. The whole graph will be smoother, as this motor is still not tuned. The shakey lined down low are from being way to rich and the shakey lines up top are from being on the lean side and having some rich dips mixed in. Overall, the motor eats up the dips and maintains decent power.
At this power, this car is not going to run 190 mph. So this power range is short of what I would like to do. Power is good and a lot of fun but again want 190 mph.I know it is hard to understand but just to go 10 measly mph more takes that much more power. From 190 to 200, it takes another 200 hp or so. The cars that run 240 mph, make 1500 hp. Really need 670 hp or so or about 120-0 hp more than when I ran the 180 mph.
