This is a dyno run made to simulate wind resistance etc.The 200 mph pull was at 12 lbs boost. The drag coefficient program only goes back to 1973 models so they entered the Mule as a 73 Nova which is actually probably a little boxier in shape than a 69 Camaro. It did 0-200 in a calculated 8/10's of a mile. Pulled 120-180 in 6 seconds. Made about 800 hp at the rear wheels at 14 lbs boost. Tires were smoking on the dyno at 120 mph. At 12 lbs boost is was making 750 hp at the rear wheels. It pulled almost 180 mph in 5th at 7200 rpm. I have no torque figures yet. This is all stuff I was told over the phone today so stuff might get clarified more by tomorrow. This is a blast... Dyno video (http://www.camcojb.com/videos/Mule200.wmv)

Yeah they were.. Charley...you may want to invest in a bit of insulating wrap on those headers or carry a good extinguisher !

You think maybe it was making power so fast it just couldn't dump it fast enough out the exhaust??--that was very bright----

Actually I was expecting to see the turbo housings turn cherry...

Ha ! That is normal for turbo setups pulling really hard. Even the wastegates were red.

The turbo pipes on my buick would creak and pop with the heat and the pipes would get reddish in color but never saw it extend into the headers-that's mucho power--Are the headers ceramic coated Charley??...

WHOA thats pretty stout. Will there be any problem with the paint on the hood bubbling from so much heat??

I bet that thing will almost FLY!Sure sounds cool.I bet the torque numbers are tremendous on that baby!

Very cool.

I think there is a problem with the temperature though. Notice that the front left exhaust port gets red a while before the others do... indicating to me an uneven extraction.

I don't think they would have made the run if there was a problem. The angle of the camera allows you to see the pass side tube heat up and you are only seeing the reflection of the driver side.

Charley:
Don't know if you have posted any info on your engine build, but I would really like to see it. What components etc. went into this beast?

Here is another video of it making 750 at the rear wheels.

Are you driving the Mule on the HR Power Tour again this year? http://www.yenko.net/ubbthreads/images/graemlins/burnout.gif

Yes we plan on driving it on Power Tour again this year.

Those custom items are one offs for your mule Charley?--Cam--Motion grind is Motion performance ??...

Most of the stuff like headers, intercooler, intake etc are custom made. Cam-Motion is not Motion Performance.

Appparently there is still the rest of the video... reality does set in at some point... watch it several times... even slow motion if need be. Uneven distribution of heat is a problem no matter what.

What exactly are you trying to say ? Do I have a hidden video of the engine grenading ? I need to be careful next time I am up near 200 mph ?

What is the latest word on wrapping headers? Some say it is good to do, others say it cracks and ruins the headers.
