BD Quick Spool Valve Install with Pics

I'm gonna try to get some video today so stay tuned. I know that there is a lot of bickering going on, but I'm not gonna lie, I'm having a lot of fun with my 6.5L (dyno, making power, video's for you guys). Regardless of the setup, it has been a fantastic truck since day one and I hope to never have to sell it. I want to keep it forever. As mentioned, the 6.5L is not the powerhouse the more modern diesels are, but that is what is great about them. Any average Joe can take a Duramax or Cummins or Powerstroke, slap a chip, intake, and exhaust on them and make them fast and powerful, but it takes true ingenuity and drive to take something that was never meant to be fast, and make it fast. The 6.5L crowd is a breed of its own, and I love that. So can we seriously stop the bickering please and negative attacks and start working to show that the 6.5L is not the dog that some think it is.


Exactly. Only problem is your last sentence. A buddy of mine has a 1996 powerstroke and we have similar size and weight trailers, he couldn't believe how good my truck pulls my trailer. So he put an intercooler on his after he saw how much it improved mine on long steep pulls. When I told him what you dynoed he said that's great but BS. I said its right here in black and white. People with a narrow mind won't listen anyway. Or just don't want to believe it.

Oh and BoostN. NEVER SAY NEVER. My buddy and I have always disliked Fords. We have said we would never buy a Ford. He ended up buying the 96 Powerstroke.
 
2500 trucks weren't available with 3.42s, atleast here in the states they weren't.

They only come with 3.73 or 4.10 and the 4.10 being the most popular.

The european markets are VASTLY different than teh US markets. You could get 2500 BURBS with S engines and all over there, and 3.42's were porobably an option with the price of there fuel. Sort of like how GM offerred 3.08 gears in 2500 pick-ups with 14 bolt full floaters for fleets and city orders. GM will throw curve balls into anything as soon as you think you have it figured out.

Back on topic, Have you considered going with some sort of control system to open and close the quick spool valve 6.5L? I could see where this sytem could be VERY versatile with a basic controller to operate the quick spool valve. The milage of a 6.2L N/A, and the power of a 6.5L turbo at will could be sweet. Or maybe you could go with an electric screw actuator that would open the valve at say 1/4 throttle and below, but allow it to go back to normal operation above 1/4 throttle.
 
I think if regulated by exhaust gas pressure it would be a nice set up. Electronic off of the current vac solenoid would be sweet as well.

Just for giggles I videoed my OTC monitor (not posted) showing RPM fuel rate timing and boost, (unloaded truck) I can start to make boost as low as 1316 rpm, 1610 is normal to start making boost under any condition. I can cruise my truck in fifth gear at 35 mph and give it fuel and start to make boost. Cruising on the highway at 2368 I get 2.5 to 3.7 depending on how level the highway is. I wonder how this valve will affect my MPG on the highway, I get 19 to 19.5 under normal driving. Don't want to cut that out.

Let me know what you are getting after the valve was installed. I think you have a pretty good track record of MPG so far.

With a "spool valve" you want it boost referenced. This can either be done with a spring pot referenced to boost ( like most wastegate regulators) or by adapting the stock vacuum system.

I would think the vac system would be the best way. It's a boost referenced system, the hard work is already done (hardware and software) and can be programmed to only activate the valve above a certain rpm vs tps%. In other words; valve shut at low percentages for throttle response and open at high % for less restriction in the exhaust.


For those who want the "stone axe", there's always the boost referenced spring pot option.

I checked again, i have 3.73 rear
 
Here are some video's. I told you I was gonna make some. So enjoy. I hope they are pleasing. I was kind of shaky with the camera. There good wind here today and my truck is a wind sail haha The first video is of the sound with the spool valve just because it sounds crazy. It didnt turn out great but you can kind of hear it. Will get better video of that later. The second video is 0-60ish. Third video is spooling. Was rolling in 4th and hammered on it, and grabbed 5th. It may not seem quick to some but it was quicker than what it was before by far.

Sounds sweet!

Slim I'll gladly be a guinea pig for a large housing and spool valve. This will be on my 93 i'm putting back together. Still has 4.10's but i have 4.56's on the shelf in case i still cant get a good pull on a load of hay.
 
Already on it Tanman_2006, will be meeting with the machinist to hash out the possibilities next week. Have to thank 6.5 for trying this, and Mazda for inventing it to use on rotary motor back in the eighty's. Old technology for old trucks, got to love it, have to be careful though to much boost on the low side of the rpm scale is not good for the bottom end. older blocks cant take it. P400 might but most others won't live a long life doing that.
 
Actually it will probably get a upgraded lift pump but as far as extensive mods, for now I am done. I am contemplating headstuds and more fueling but that probably wont be until next summer. And thanks guys. A lot of hard work and labor has gone into the truck. Glad it is appreciated. I love my 5 speed too. just need to get hard shifting down smoother. It is rough in the video.
 
Well i hit the dyno and learned a few things. I can post up a pic of the sheet later but power was 250rwhp at 3500rpm and peak torque was 420ft lbs at 2700rpm. So where peak torque was made was brought down about 300rpm but I did lose 25rwhp and 10ft lbs. I think I can explain the hp loss from the valve not opening until 15psi and choking the motor. I am going to try to bring that down to open around 10psi instead of 15. Also am gonna need water injection I think. On my final run the motor started to heat soak and I lost all my power. It was struggling the last 700rpm or so, so we shut it down to avoid problems. It runs fine now. Weird is my power went down on the dyno but on the street it is faster and more powerful down low than before. Who knows. But he did give me the dyno run for free so that was cool. I guess I will just have to take it easy on it.
