Thanks, TDR Staff

Competition Jesup

Just got the call, on a Superflow dyno, 550+. I'll post details as I get them.



Thats getting into Sleddy range, I may start looking for more fuel..... or retire...
 
Why, wasn't Casey one of the CLAIMED 600 hp PSDs years ago? :rolleyes:



Pennsylvania Ford, Scott, Sleeper, Ford, well , coma would be a better term.
 
One of our TDR members here Greg (Dockboy) has a single turbo F250 excab 4x4 PSD thats over 500RWHP ,and over 600 on nitrous. he is a friend of mine,his truck is incredible,i have ridden in it on #2 only,and its downright insane for a PSD. The thing has run atraction limited 12. 87 at 108mph,spinning all 4 tires past the 60 ft mark,and it weighs 7975 lbs. Like myself he plows snow commercially,and his truck is no joke. There isnt a doubt in my mind that once he gets his stock DT530 injectors worked,and if he does twins he will be well over 600 on diesel only. He isnt even cleaning up the smoke with his nitrous now,doing around 600RWHP,so there's more in there. In all honesty i was never impressed with the PSD at all,until I rode in Greg's truck.

Thank you. I haven't ever seen many folks mention dynoing on a Superflow dyno, but if you have the chance, do it. The Superflow is ten times the dyno the Dynojet is. I hope to gather some folks for a dyno day up here sometime if anyone is interested. There is definately no problem getting the truck loaded down on this dyno.



Anyhow, here are the numbers:



Uncorrected:



Max HP - 552. 2 / 897. 8 at 3550



Max Trq - 514 / 1060. 7 at 2550



Corrected:



574. 9 / 1103. 4



The Superflow dyno also has a correction factor that will tell you about what you would make on a Dynojet:



608 / 1166. 8



Max boost was 61 psi.



Here is a link to the dyno sheet. Dyno Graph I will try to get it scanned if I get time to swing by the office tomorrow. My scanner at home is a piece of crap, so I just took that terrible picture of the sheet. As you can see from the sheet, I should have turned it a few more rpm as the power wasn't dropping off at all at 3600. The turbos didn't spool till about 2500 rpm. If I could get them to spool a bit quicker I bet I could produce some monster torque down low.



Sled Puller is afraid, I can feel it. :D

Johnboy3,



Snowman mentions that your truck is a single turbo, but in your reply above it sounds like it is twinned. Which is it? Either way it is still impressive for Ford, although there are some down here by me that would give you a run for your money, believe it or not.

Gene's gettin worried, we are sneaking up on him, just remember JohnBoy has alot of tuning (oil pump) to do



:D





Congrats

And mattymac,



Gene titled the thread, not Johnboy ;)

Ted, it's twinned. I'm using an h2 and h4. I tried to make a couple of nitrous runs, but I had system malfunctions. So, the only good numbers I have are #2 only runs. I'm well aware of the monsters you guys have running around down there. I'm very interested to get a couple of you guys that know what your numbers are on this dyno. One of the coolest things is that you can enter the mph you want the test to start at and it will hold you there until you are ready to go. For example, 50 mph was the beginning of my direct gear so that's where we started the test. I would spin the dyno up to 50 mph, and then I could put the pedal right the floor. The dyno would hold 50 mph until I pressed the go button on the control pad. I was able to get the turbos starting to spool and the egts up before I let it rip. That was a big help in getting the turbos spooled. Then the rate of acceleration is adjustable. We set it at 12 seconds for my truck. So, the dyno would hold load on the truck making the 50-95 mph last 12 seconds. This worked really well.



I'd like to get a few of you guys up here for a dyno day if anyone is interested.
 
Good Job Johnboy !!! Nice numbers. Gene should be worried..... Gene will retire and take a full time desk job with the DHRA and be known as the legend that was... ... ... ... ... ... ... ... ... ..... SLED PULLER!!! :-laf

Thanks.

I do believe Sled Puller is finished. I talked to him today and he more or less said he can't compete with my big Ford anymore. One legend down, who's next? :D



Here's some better dyno data that I finally got scanned in:

sorry for the confusion boys. Johnboy3 I would like to make a trip up to that dyno sometime this winter, and DockBoy, maybe we can all get together early next year at one of the local tracks.



Ted
 
Sounds good Ted :D



I only live about 10 mi. from Cecil County Dragway and run there quite a bit :) Kevin(MD500E) and quite a few other TDR members come down also ;)
 
Sort of amusing how owners of the high HP fords are members here :) Not knockin you guys, I have tons of respect for the things you are doing with your trucks, it's just amusing how you high power guys talk on here :)
