OK, I've got something hopefully mean, and definitely green in the trailer.
Dyno test & tune is tonight. I have a GoPro on the roll cage, and a separate camera to shoot video from outside the truck.
Steve.

I'll have my GoPro installed in the truck's cab, a second video camera outside the vehicle, and my iPhone in my pocket.
I'll try to post numbers as soon as they are available, with as much follow-up video and dyno sheets as possible.
Steve.

Yep, and I have a diesel Mercedes Benz waiting at home. I'm all diesel at this point.

Best of luck with your pull.
Will this make her a dyno queen till she gets out on the salt?

I made 4 or 5 pulls (can't remember exactly). I will have video(s) loaded up tomorrow, with screenshots of the dyno results. I'll have to wait for the reports to be emailed to me.
My boost controller wasn't doing what I wanted it to (because I didn't have it plumbed correctly).
The dyno at Ranken Technical College was pretty sophisticated. The instructor plugged in some values for weight of the Rampage, some aerodynamic estimates, estimated altitude data for Bonneville. This was all intended to load the dyno as if I were actually on the salt flats.
I ran up through 1st, 2nd, 3rd, and into 4th gear. We started all the pulls at about 2000 rpm, then I rolled into the throttle until 5500 rpm or so.
With 30 pounds of boost, the turbo power hit HARD! Even in 4th gear, it pulled very, very strong, up to 120 mph on the dyno.
I'll take some time to upload videos from the external camera, GoPro camera, and probably a few still photos. It was a very good night!
All in all, I was extremely pleased with the performance of the whole setup.

That is pretty impressive at such a low number RPM. I figured in the 1.5 you would have a little more than that but it would be in the low 5,000 rpm to 5,500 rpm range. Did you turn up the fuel at all or just leave the screw where it was. Either way that is 27hp that you didn't think you had and at a lower rpm. So you may not have to run it as hard as you thought?
How many miles do you have on it now and does it feel nice and freed up or is it still really tight?

well stock, the 1.5 made 48hp. so you have made 3.5 times that at the wheels rather than the crank, that is very impressive. it will be interesting to see the dyno plots too. but even more interesting to see you shatter the bonneville record. it'd be sick if you could beat the 2.0 record with your 1.5

I think I could have spun more rpm's with a lower gear ratio in the trans.
I hit 120 mph on the road-simulation dyno, pulling a simulated load (as if it were actually running on the salt flats).
With lower gearing, it definitely would have hit higher engine rpm's.
On paper, and on the dyno, I should be able to be competitive against the existing record. Of course, the kicker is that the race isn't run on paper or on the dyno. I have to make it happen on the salt flats, and anything can happen out there.
Steve.
