I've been seartching now for a couple of hours and I can't find the post on the subject. I have a D & S Dual intake for my Blue Flame and and I'm using it with a set of Fenton Headers. I've seen that you can buy a heat shield at Langdon's so you can run the radiator water through it, or put in steel tubing between the headers and the intake. My question is why do you want to heat up the intake, don't you want to keep the intake cool? Or am I a complete moron? And - If I do want to heat it up, what is the best way to go? Exhaust heat or water heat? Please help me out Klaus
Heat Risers As you live in real cold weather country , I'd suggest using the exhaust gas heat riser tubing kit , the idea is to warm up the intake manifold's plenums & prevent fuel droplets from sticking to the interior walls & creating flat spots . Engine coolant kits take forever to warm up . Of course , using a dual exhaust manifold means you don't really want it to run the best it can as a merged exhaust always works better in street driven engines . You could merge the two outlets just below the flanges too , that'd work fine , different ways to skin this cat . Let the flame wars begin ! .
Your headers are on the way Klaus. http://www.inliners.org/tech/why_you_need_heat_to_your_inlet_.htm http://www.inliners.org/tech/tech4.html
Dual setup solutions. Hey there Claus and other guys Tom Langdon lives in the cold area of Michigan so using his setup has some advantages but there are still some questions left to answer incase the waterheating versus exhaustheating setup solutions ? I dont know if you guys have heard about block or water hose heating ( Not meaning the squire Canadian forrestry cap ). Most cars and trucks use an engine block heating divice in my country wich is mounted in one of the frostplug holes or cabin inlet hoses and heats the coolant water and engine oil as water circulates in the system when getting warm (1/2-1 hour in el.contact) before starting your truck. There are hose heaters for older trucks made in China of a good quality with a high watt output. Chinese model availeble for 45 US dollars ; http://www.engineheater.cn/main/home/htm.php?nowmenuid=9 Defa model very expencive; http://www.tuningspesialisten.no/public.aspx?pageid=36467&catID=15872&Product=37637 O.K my point is ; Without installing the block or hose heating device for cold weather use (attched picuture) Toms warm coolant water solution has no influence on the icy carbs at once , but will have when engine coollant water is warm anough to supply the heatrising plate continueous with warm water ! This takes some minutes offcourse until your engine is on temp 160-180 F and the thermostate opens , and first then your engine runs as it should . Its not allways in winter time the cast iron part of your carbbody freezes .This freezing fenomen occures more often when temps are above zero and when it gets hot outside ! The older models Rochester, Carter, Zenith and other downdraft 1 barrel carbs all can become icy . Basic fysics tells me that CO2 exhaust warms up the heatrising plate quicker then warm water does as the distance from your thermostate towards the heatrising plate is much longer and the cold water run takes longer time to heat it up. But i`ll gues that in a warmer climate cooling of the engine and carbs is more needed then in a colder envirement. Using the Carter Holly 2 barrel carbs with el. choke by mounting an adapter in between the carb and intake manifold makes this icing fenomen allmost disapears , but Tom still advices to use the heatriser plate with warm water connectors ? I am going to try out both options to see if any of them gives a better aprovement I will get back to this subject later again and inform you guys about the results. Just some thoughts Martinius.
We don't have to worry about any of this as we are in the middle of the desert & cooling is more important than heating anything
So thrue , so thrue. like Volker did with his Fenton dual setup is a good solution! He made some very good pictures of it to.
Block Heaters Martinus you care correct , warming the coolant when the engine is off results in east cold starts &faster warmup , almost instant heater output too . Most DIY'ers don't like to mess 'round with frost / welch / freeze / core plugs , these days you can buy heaters that are easy to splice into the lower radiator hose ,they work very well indeed , Mid Westerner's use them on various engines left out in the windy sub freezing temps , Diesels especially like this simple , cheap & effective method .
