Duramax versus Cummings

[150aintenuff]

I own a PSD and was asking Keith if 500 was possible.

sorry if it was off topic

I'd have to see a dyno sheet to believe 900+rwhp. I have not heard of anyone up there that has proven it on a dyno yet. Lots of claims though.

Here is the results of the dyno day we had ,some of the guys were spraying methanol/water injection but no nitrous or propane. Why is 900rwhp so hard to believe on the bottle ? And seriously who sprays on a dyno? unless you want to pretzel your driveshaft .........there is no control of driveline slop on a diesel on deceleration and it tears **** up ,im sure your already now this.
another one for you is 20# bottle 2 1/8mile passes how many HP of juice does that add up to?

WHAT WAS THAT?????? 245 torque????? thats not a PSD is it????? I feel sorry for that guy

seen something funny today. a 95 or so camaro is in the left lane in front of me, and we pull up to a stop light next to a duramax 3500 SRW, with a 20ft or so flats boat in tow. now, I can hear the camaro revving on the truck, it has z28 badges, and sure sounds like a v8... but I can barely hear it above the duramax spooling the turbo against his brakes. long story short, the duramax/boat combo walked the camaro like it was sitting still for about 500 ft untill he hit the brakes. it was the funniest thing i have seen in awhile, but the side of the poor boat was black as coal.

thinking about it, that truck had to have more than 3 times the torque of the car. which would be in the neighborhood of 800lb feet.

For kicks, go to the website I talked about and do a search.(dyno horsepower) I took the time and a truck set up identical to mine except he has stock injectors,doesn't run propane, and is a dually pulled a 795/1502(superdiesel I think is his name on there) The cummins are still king but given the amout of time the duramax has been out its pretty sporty!!! I think superdiesel still only runs low 12's but its probably because of the extra weight.

I'm not saying it's hard to believe. I'm just saying that NO ONE has ever posted a real dyno sheet showing this. We have sprayed trucks on the dyno making just under 800rwhp. You're not going to do anything to the driveshaft that wouldn't have 100x more chance of doing on the road. The dyno has less load than the same truck on the road.

Yeah, and I've had plenty of dyno experience. Besides the 5 years here at Diesel Dynamics, I worked for Dynojet (the dyno manufacturer) for 5 years as well.

Oh, and who sells a 20# bottle? I've not seen anything between 15# and 25#.

[CDave]

NOS sells a 20# bottle.

Thanks CDave!
