Thanks! And yes, I would like to do that when I do the other brake upgrades.Looking great. Did you have any future plans for possible hydroboost braking? Those units take up far less firewall space than the vacuum booster. Your engine compartment is really looking good. Very neat and well organized.
Sometimes I think it might be kinda funny to sneak a stopwatch in the corner of all the shots just to show how long it really takes me, without the magic of editing... but at the same time I'm not sure I wanna know if (when) it takes me 17 hours to make a little bracket.Nice movie, wish I was such a fast worker.
Early on I had thought about changing the pedal itself... but there's just something funny about the new clutch pedal looking like a clone of the brake pedal. Well I'm kind of curious to compare the difference since I've never driven on hydroboost brakes. And honestly I can't see much else use for that vacuum pump afterwords, unless someone has another idea? Most likely going to look for some sort of replacement in the future (e.g. air compressor). And my brakes will definitely get more upgrades in various phases (more stainless hose, fixed calipers, big rotors, etc).Yeah, normally the clutch pedal has a smaller pad than the brake but your solution looks great. One thing I was thinking, since you're working all that out, why not change to the hydroboost now? You could have that out of the way when the future brake system goes in.
Crap... kinda figured there would be few uses for that vacuum pump. Ah well it'll be an interesting experiment until I get to the future brake & steering upgrades.Vacuum on hydroboost setups could be for things like heater/ac controls or cruise control. On most modern diesels they changed to an electric vacuum pump since there wasn't a need for the big mechanical one. I believe there are even vacuum lockers for differentials. Otherwise, it would have little to no use. An air compressor would be a possible, but there you'd need to figure out the ps setup. No adapter that I know of that fits the stock pump to one of those. There you'd use a different ps pump and remote reservoir. Those type pumps are usually higher pressure since they came on medium duty trucks but they can usually be adjusted to work with the hydroboost system. There were single and twin cylinder compressors and they were even on P pump engines. Here's a photo of a twin on a 4bt with the VE injection pump. Like I said, they came on P pumps too. One note, those puppies aren't light because they are cast iron, not aluminum. Would require a bit of research for your engine to get the correct mount and braces to support that pump.
Twin hole pump would be overkill for sure, at least for my plans with this build. I would love an exhaust brake, and I have a ton of room under the turbo where I could plumb one in, but I think you can get them in both negative/positive pressure control.Yeah, that twin cylinder air pump ain't a small thing. Those were mostly on 6bt and 6ct engines but as you see in the photo some 4bts got them. Those were Bendix Tu-Flo 550 or Tu-Flo 750 units and the bare compressor weighs 53 lbs. Probably overkill on a 4bt unless you need a lot of air. Primary use was air brakes or air suspension. Another possible use for the vacuum pump I failed to mention was the exhaust brake system. When Dodge offered the exhaust brake the gear driven pumps were no longer used and a belt driven unit replaced it.
Yeah they sure can get pricey! I have the 60lb springs already installed to deal with the 4k governor springs I put in the pump. It's not something I'll do right away if I do, but nice to know I have enough space... unless I utilize that space for compounds :lol:The Dodge factory optional exhaust brake was offered on '03-07.5 trucks with manual transmission and I believe '06-07.5 automatics. Those units came from Jacobs and they all were vacuum operated. The primary downside of those were the belt driven vacuum pumps had a bad failure rate. It was later discovered and corrected that the issue had been the size of the pulley being used. When they went to a slightly larger pulley the failures stopped. In the aftermarket, I believe all those use a pressurized system instead of vacuum. One thing to keep in mind should you decide on using one of those braking system is you must install the HD valve springs on the engine, at least on the exhaust side. One downside of all those systems is cost. They Jacobs units are designed for the 3.5-4" exhaust pipe so it would take some type of adapter to use it on an HX30W which only has a 2.5" outlet. They aren't cheap either unless you could find a used one. Those seem to be kind of scarce anymore unless you could find a Dodge dealer with one sitting on the shelf they want to get rid of.
Thanks! Just knocked another off that check list ✔Great video. Love that check list on the windshield.
