1G 6266 dyno!

[1cleangsx]

First of all I just have to thank Steven@biglady112 for his time and knowledge with this car. This day went better than I could’ve hoped for and FAR exceeded my expectations. Final numbers were 701whp on a mustang dyno at altitude

Great numbers Jeremy! I think our cars would be toe to toe!!!!
Stoked for ya!

Thanks Marty

That things spooling!!!! And making some amazing power

 

[1cleangsx]

Thank you!

I think 730-750 is doable. The spark plugs say it could take another degree of timing. It picked up 40whp going from 16* to 17* total timing. Another degree would have been 10-30whp I bet.

And it was out of ignition. It wasn’t far from being out of turbo but, it would not hold any more than 37psi. It would break up at 38psi. With a little more boost and timing like I said, 730-750 is where this guy would end up. Not bad for the old 6266 and stock ignition.

Good job Steven! Mine maxed out at 18* on E. I wish Jeremy's could hold 40lbs. Every lb makes a difference when you start to get up around 35 on my HX40. That thing holds 40 and I wish his would too.
Awesome tune and #'s!
I congratulate BOTH of you!

The cars getting an oil change in the morning and re fabbed oil drain, I guess my only blunder for the day which Steven pointed out was my wastegate dump tube shooting flames at my oil drain

If it was about out of turbo, I know a kid that has an 88mm Precision

I’m gonna change the orientation of the dump tube, replace the hose with a new piece and heat wrap it

I couldn’t be happier with the car right now, we all know the ups and downs of owning these cars, I’m just relishing in a good day right now

 

[1990TSIAWDTALON]

CHERISH IT.
You deserve to!
Have fun, get a smile, disappoint V8s!!!!
You know it's probably a 10 flat or better car man. ENJOY THE SHIT OUT OF IT!

With the tire he currently has it would take a miracle pass to run a ten second pass at altitude. I think the car will run low 11’s to high 10’s in the real high 120’s from what we learned today. Low 11’s is highly likely given we went 10.99@142 with a similar shitty tire with 60hp more.

Normally they stop in the 13-15* total timing range from what I see here. Especially at this power level. The plugs said they wanted more, so I gave it to them. He came in 4* too aggressive. I pulled six and added a degree back at a time until it said it was happy.

And he is right on the edge of turbo. Just three weeks ago I had a 6466 on the same Dyno that gave up at 38psi. Verified through back pressure. That same car when it was on dsmlink and the same combination gave up at 41psi. Only major changes are time of year and the car is now on FuelTech at the new 38psi.

No applause needed. After 24 years of doing this I better have my shit figured out behind the keyboard.

I’d say you do

I like it!
What is "WCF"?

What is "WCF"?

I'll let others correct me if I'm wrong but I believe it is Weather Correction Factor. They were at very high altitude I assume, given their locations. Which along with temperature, humidity, and other environmental factors will affect the power an engine is able to produce. The WCF is a calculation of what the power numbers would be if the vehicle was in a different environment. SAE defines a "standard day" which was likely used to calculate the WCF number.

"The most common are the SAE standards. The older J607 standard considers that the engine was run on a 60°F day with 0% humidity and a barometric pressure of 29.92 in-Hg or the newer SAE J1349 standard of 77°F (25°C) day with 0% humidity and a barometric pressure of 29.234 in-Hg (99 KPa)."

Yeah, "Weather" is the key word here, for me. Altitude is by far the biggest part of the correction factor when you are around Denver, and I don't think of altitude as "weather". But that must be what it is. It's funny because I spent a couple minutes internet searching "what is WCF on a mustang dyno" and all I found was a couple guys guessing at it like we are. I didn't see anybody quote from the Mustang user manual.

No biggie though. The correction factor, whatever it is named, is apparently 701.2 / 580.9 = 1.207
That's just right for Denver altitude where the average atmospheric pressure is only about 12.3 psi versus 14.7 at sea level.

 

[biglady112]

Dyno numbers should be taken with a grain of salt. It is merely a tool for testing and comparing repeatable results. We don’t race the Dyno. So the numbers don’t mean anything. If it can lay two graphs on top of each other back to back with no changes, then it can be used for measurable gains.

Nothing more, nothing less. All that matters is if he is happy with the results and what trap speed the car can produce. The rest is bullshit to pat ourselves on the back.

 

[1cleangsx]

However Steven IS the MAN

 

[Car Cannibal]

The weather correction doesn't take into account DRIVETRAIN loss, because a Mustang Dyno, AWD and then altitude isn't just a 18.5% loss.
If this is an auto then tack on anywhere from 3-8% more for converter slippage.

Great numbers, they're most likely higher than 700hp at the crank.
