Did 5 pulls today. 2 were without methanol(Only #18 posted); 1 was w/o methanol but we cranked up the Kenne Bell Boost-a-pump (#20); 1 was with it cranked up and on methanol (4th in a series of 4 non-stop runs...#21), then finally a 5th, on the juice after a cooling off period of approx. 15 minutes. (#22)

Wow, what a difference that made. You can see the results on this sheet. HP was up, Torque was up (through the entire RPM range I might add) and ARF's were much lower than they have ever been. Funny thing is boost was down. :confused2

Waiting on UTube to load and an email that will show the 4 days of dynos, best runs in the series of 22...:M5launch:

I am VERY pleased with the results. You can clearly see in the graph when the methanol comes on. Thanks to all for patience and understanding.

Nice! You're making the 550 claimed hp at the wheels!

AWESOME Steve. Simply amazing. I bet that car a BEAST to drive...... Congrats!

 

[mamsterla]

Congrats Steve - where did you go for Dyno? Nice numbers.

havasusteve03Beast,

I can't wait to see & hear a video or two. I have seen many of your dyno vids with the clean chrome OEM wheels & the lovely Borla exhaust... ! :cheers:

Congrats Steve! All of our cars should bow down to yours. All hail the King Beast! Now you just need to find a smaller pulley.

 

[930chas]

Was this on race gas? Some of those pulls seemed pretty lean. Do you have a wideband installed in the car?

 

[Clemster]

Awesome numbers, Steve! I have been anxiously awaiting your results and I'm seriously impressed with your numbers. Your car loves that dyno. lovelove

As Charlie points out, your AFR's are lean. Are you pulling from a bung or a tailpipe sniffer? If the later, how far up your tailpipe is the sensor? :3:

Are you running your customary 50/50 blend of 91/100 octane? You discussed going to straight pump and allowing the meth to provide the extra octane. If you're baseline numbers are on 91, you are a true stud!

Your best pulls after the cool down showed a major increase across the board. A little surprising being that the major benefit of the meth (besides the octane) is cooling. You did mention that 15 minutes earlier you did repeated pulls, but those increases are major.

At some point we need to have a conversation about how you dialed it in. This mod is in my near future....minus the porn quality tank.

Congrat! :cheers:

14.5 AFRs at peak torque - that's a recipie for KABOOM. Based on the HP and tq plots, I don't see any timing being pulled as a result, that's really really really scary in a high-comp, FI motor. I usually put 12.5 as the yellow light in my head, and 13.0 I start to panic. I think you need to have the DME remapped.

Hi Mike,

GTR High Performance here in Rancho Cucamonga. It is where i have done all my dyno runs

Thank you very much Edwin....I appreciate your comment, however I need to correct you...There are AT LEAST 2 more King Beasts (Twins) and the Uber-Beast!!! I think we all know who that is

Was this on race gas? Some of those pulls seemed pretty lean. Do you have a wideband installed in the car?

Nope...No more race gas, pathetic 91 octane and the Methanol. With regards to the AFR's, I have a wide-band PLX AFR system. The dyno #s were taken from the bung ahead of the SS CATS. It is a narrow-band system. That may explain why my AFR's on the dyno are high, vs. what I am reading in the car under normal driving conditions??? I have seen 12's and 11's in the car while dialing in the meth/boost-a-pump system. Never saw 11's once during the dyno run. Can someone educate me/us about wide-band monitoring vs. narrow-band?? I trust the wide-band more...

Adam, Thank you sir!! Hopefully I answered some questions above. I was really surprised at the AFR difference on the last run, along with the drop in boost???

Part of me wanted to do a back-to-back, but 5 pulls in one day is pushing the envelope..:1zhelp:

Matt, I hear you on the #'s. My car, hs historically always run on the lean side, based on THAT dyno. If you look at the 4 previous run days, N/A or otherwise, I am always in that "zone" Again, not sure if it could be the narrow-band readings vs. wide-band?? As always, I appreciate your thoghts and expertise

Steve

I forgot whether or not you're running cats? that can drop the O2 reading by up to one point. The hotter the cat, the higher the AFR - why your "cool" run most likely had the lowest AFR.

Narrow band sensor? explain.

All 4 OEM sensors are wideband, as the dyno's should be.

One thing to be careful of: If you're running a leaded race fuel, you will munch O2 sensors with a quickness which will result in faulty tuning - the ESS tune, IIRC, gives a certain authority to the O2 sensor to allow for autotuning/ AFR trimming.

Do you have an in-car WBo2 readout (using a pre-cat sensor)? If not, maybe look into a setup: MTS Modular Tuning System

Congrats Steve!! 550 is a SICK #. Bring on the E60's!

Matt,

I am running the Supersprint CATS and had an extra bung installed ahead of the OEM Pre-CAT sensor. That is what I use for my PLX AFR gauge readings. It is a Bosch wide-band sensor also. As I said earlier, the adjustments I made to the Methanol injection system prior to the dyno reflected consistant 11-12's during hard pulls, on the Meth. Thats why I was comfortable with going to the dyno. Hell, I had to turn down the methanol orifinally because the car was running FAT not only on the gauge, but by butt-o-meter.

I have never run leaded race fuel. When I was running the 50-50, it was unleaded.

 

[Hdhntr23]

How does it feel knowing you have one of the most powerful and fastest E39 M5's on the planet? I would bet there are less than 10 total that can pull that kind of number.

awesome! that clears it up! Tell that dyno shop to replace their sensor! I've seen too many dynos keep sensors for WAYYYYY too long. Not to mention, sniffers are rarely accurate with the amount of exhaust leaks many cars have.

 

[Bimmerbear]

What boost pressure were these pulls done at? What psi were you expecting (i.e. your pulley rating) and what did you actually observe?

 

[Mike S.]

Great numbers, Steve! Congratulations!

 

[Lunker325]

Nice! Congrats Steve, that is one strong beast!

 

[Ransidd]

Congrats Steve, you're an inspiration to all us ESS owners!.

Are you running 50/50 or pure Meth? What brand if pure?

I've been contemplating getting the HFS 6/3 Meth kit but keep going back on forth if I need the extra power. Plus after some "Mexico" runs I really need to address my clutch, as it failed hard on a 3-4 powershift last night. Nothing like slamming 4th and watching your Tach go up and speedometer go down lol.

I'm sure I'll get a meth kit here shortly with the 92mm pulley. Not sure if I need the HFS6, any thoughts on the HFS3 kit? Also, probably can't afford the "Porn Tank" as Adam calls it, but if you don't mind, What was the cost? Or PM me the cost.

You need to take a Wed night off next month and come down to the San Diego Monthly meet. Lotsa eye candy.
