I put down a number I am pretty impressed with last weekend. Now we are debating on trying to make it to 750hp on the SO without nitrous. A friend of mine thinks we are already pretty close to the highest power SO pump. So I figured I’d ask you guys since this is probably the biggest active group of VP guys. 
 

Dyno was at an old gasoline hot rod shop so it was only set up for 1,200 max torque. 

Oh and the tach pickup kept falling off which is why torque drops off on both pulls and print out is in MPH. 

I haven't really kept up with it in a while but mid to upper 600's is what I remember being the most without 'help'.  Ever since the CP pumps and the 6.7's came out not much discussion about VP horsepower anymore.  It's good to see somebody out there still paying homage...congrats! 

Thanks Bullet! When this engine lets go it is getting a 6.7 common rail but in the mean time I want to see what an SO VP can really do.

I think maybe you didn’t count your zeros!

You would be right. 1000hp, is that better 

Over 1000 is the record but 750 is good for a so.

Stainless Diesel is I think 1,049 HP on fuel only on SO VP44.

Ah that’s right. I think they even have a YouTube video of that.

Yes sir there is a video of that.

I didnt think anyone made much more than 500 so thats impressive.

I just realized your not far from me over in Weathorford. I just hit you up on instagram

Thanks @98whitelightnin! It escalated pretty quickly from “I’m keeping it stock” to “400 will be enough” then “well let’s put compounds and see what it does” and finally “540! That can’t be right. Let’s work on the tune and try a different dyno.” 

I have done the exact same over and over again. My last p-pumped truck made 700 something and almost 1900 ft pounds with compounds and a shot of nitrous.
