    I got some .006” nozzles with built in filters and check valves. The pair are rated at 100ml/minute …like 1/3 or a soda can.

    Going to mount the in the fan shroud above the heads to prevent moisture in the heater boxes.

    Planning to use an empi 180 degree fan switch to control a relay and 150psi water pump.

    I want to know who is running the 1/38-inch exhaust. That is how you make torque.

    Funny you said that…  I was thinking that to be a TRUE statement and already hashed out…. 😎  smaller exhaust, better tourque down low, which is what you want in a bus!!!

    I have some thoughts….

    HEATERBOXES make heat…  why mount the BEST heat generating source we have right UNDER our bigger HP heads???????? 😎

    REDUC  BOXES….     Cost Power.. Period.  for many reasons…

    Does the stock fuel pump “pre-heat” my fuel?????  I have boiled gas in my filter thats before the carbs before…

    Doesn’t an open header run cooler than a j tube through a heaterbox???  seems logically…

    AND, without a heaterbox and all clogged up with tin down there…  I bet the heads instantly run cooler…. especially on the hwy!!!  which is mostly what I have to travel on to get to the campouts!!!!!

    I’ve heard a lot of people say the stock fuel pumps bring a lot of heat into the equation. It’s sitting right one a hot location. The center of the case. Gotta be bringing some heat. If you just run an electric pump to a “T” in the front piece of tin in front of your shroud, then just split to your 2 carbs, then the fuel is sitting in the engine bay a lot shorter of a time. I just hate extra shit. Wiring up a fuel pump and mounting it has always been more than I want to do. There is a spot on my case for a fuel pump… so why not use it? Haha

     

    but it seems some of this “extra” stuff really helps. Extra oil filters. Bigger sumps. Bigger carbs to push the bigger motors. It just depends where you want to draw that line I guess. But if you could just run a header, and figure out another nice way to pipe a diesel heater in, that’d be cool. I would just hate for a heater to go out. Your motor is already running and creating heat…. so why not use it? Lots of pros and cons. Like Smurthwaite said.

    Life is a constant negotiation

    I personally run electric fuel pumps on my own buses as well as customer buses

    an open header (J tube) won’t necessarily run any cooler because it doesn’t have the cool forced air from the fan blowing over it all the time.  A regular “j tube” requires the turbulent air from under the bus to cool it, and if you’re not running “industrial” sled tins then the hot air from the heads is blowing right onto the J tube. Whats more critical is how the hot exhaust gases can leave the head and exhaust primaries.

    the heater box serves as tin to deflect the hot head air rearwards.  When using plain J tubes it is definitely beneficial to run industrial tins.

    head temp is based on a lot of things, but its not very much affected by a heater box versus a plain J tube.  Whats more important is for the head to be able to flow the hot exhaust gases out.  Stock heater boxes on a 2332 is a SURE way to have hot heads (and leave a lot of power on the table)

    and yes, 1-3/8 J tubes can be ideal for smaller displacement engines.

    a properly built 2332 in a bus should have at minimum 1-1/2″ exhaust primaries, but realistically should have 1-5/8.  1-3/8″ will not increase torque, only heat with that size engine.

    heres something to ponder and maybe this is digging into it too much for you…but a 2332cc has to WORK less to maintain 65mph than an 1835cc.  all else equal the 1835 is working at a higher percentage of its capacity, requiring more throttle input.  More load = more heat.  So, if a 1835 with 9.0 compression can bomb down the road at 65mph all day long and run cool as a cucumber than a 2332 inherently will as well.  (I only use that example because one of my buses has a 1835 with 9.0:1 compression, .045 deck height and redux boxes with big 215/75r15 tires.)

    we’re only trying to help, don’t take anything the wrong way 😀

    oh and its not the reduction boxes fault

    Hey JJ!! How’s the back feeling? I need to come visit y’all!

    im thinking that statement is referring to choosing between 2 sizes of primaries (ie 1.5” and 1.625) the smaller size will have better torque.

    😎 😎 😎 😎 Ya know, It is EASY to take it the wrong way….  Kinda like if I tell you I put more and harder miles on my bus than you do, don’t take it the wrong way….. 😎  😎  😎    “With all due respect and I mean ALL DUE RESPECT, ”   😎 😎  😎

    I agree with everything you guys say, and have and sometimes still, build busses that way… but since I have started camping MORE and MORE especially in the winter,,,,   I want more and better heat and up until lately, only stock boxes actually put out good heat… and I am hear to tell you, three engine’s later… It tears up big 2 liters…  😎  😎  😎  Your right, I’m right, were all right… 😎 😎  😎

    we are all just trying to help each other out, and maybe help someone else avoid the same mistakes we made.  😎  Keep the idea’s coming… we are just helping out a whole group of people who don’t want to post up…. 😎

    Hey JJ!! How’s the back feeling? I need to come visit y’all!

    back feels awesome… Haven’t heard a PEEP out of you…  I have a certain project you can fix… 8-(  I have had the worst luck with that vanagon.. 8-(

    I think any real heater box up under our heads is adding heat..  I think wayne is onto something with the empty heater boxes with larger tube…. and a diesel heater.. He has heat AND defrost…. 😎  and no massive heat source under his POWER source… 😎

    Fuck… I’ll get it squared away. Next time it bucks n shit I think unplugging the alternator might be the fix. I’ve ran into that similar problem maybe 6 months ago here. Like it’s charging the system wrong or something.

    I got you JJ. Figures this swap would be the one to fight me..

    Do something

    The elusive Kombi motor.  Franz Built about 10 plus years ago, I shouldn’t say this… but I don’t think it has ever been out of the bus…. 😎

    Only leak I had on it was the oil pressure switch, which is common as cold water these days… 😎

    2276, steve tims stage two heads, web 218 cam, straight cuts, big A1, 9.1 probably…  runs like a top!!!  44 webers..
