ohdamn... how much did THAT hurt? i thought getting it on my hands/arms was bad enough...

props!

Well i can tell you taht it was not pleasant. burned pretty badly. and it almost got in my mouth too, which would have been much, much worse

hot gasses flow better so insulating the header does make more flow but what you really want is to keep the heat in the gas and out of the metal. Wrap doesnt do that but ceramic coating like jet hot does. works real good for getting power out of bike engines and old jags

hey gearbox, i think this is another idea if your in a cold climate

everybody coming up with newer ideas to bypass this.. good job guys

Is that a 3 way valve? Cause otherwise, how would the coolant get to the next point?

That's my pic. Yep, it is a 3 way. Bought it at Lowe's.

haha, repost within a thread, j/k. anyhow, i got the 3/8 brass barb connector and after reading that different metals mixing together with coolant promotes corrosion so i went out and got a plastic piece. i later saw the same brass piece at a auto parts store and read the information on the back. to my surprise, it's recommended for use in cooling system. so i guess brass is more durable than copper?

Let me ask you this? I did the mod about a week ago and I still notice my intake is hot even though it's still a bit cold here. Do you think it's the hot oil vapors coming out of the valve cover breather. I've searched on this topic and found all different answers. What do you guys think, cap the intake and put on a dump tibe or breather? It's hot right by the bend above the TB on the AEM sri.

Brass is good for coolant, copper is cheap, **** for metal. Anything will corrode copper

that's good to know, now i'm debating if i should swap the plastic vacuum tube for the brass again.

Use the brass for the coolant. I have used it for a few weeks and so far no corrosion. Plastic parts are safe for vacuum and air lines; i just used a 1/4" t fitting for a boost/vac gauge tap.

I did the mod without the brass pipe, used the stock tube. I'm wondering about the hot air coming from the valve cover breather to the intake, it's still getting hot?

well now I don't know what to do. I asked a mechanic and he said never let coolant touch metals other than those on the car (ie aluminum). It won't corrode right away, but over time you will have metal flakes circulating in the coolant that can damage hoses, or even worse engine stuff.

I thought of a plastic tube, but wouldn't that melt? I'm back to stock now and it sucks how hot everything is, and I really wanna solution. There is NO way I can get that bottom hose off to connect the first one in a loop. There's just no space to squeeze that clamp with pliars. So I'm stuck...

about the oil vapors, I've also people say that the air moves too fast to get heated by the tb and vapors. But then again there are dynos showing big temp differences before and after so obviously it matters.

I can just imagine how hot the air is coming out of there, what ould you do gearbox, i'm thinking a tube to a breather filter byt eh strut mount or something. Would you do one?

 
Rep Power: 374

you can get mini "k&n" valve breather filters at walmart for 8 bux each in the ricer section.

I'll just try not to be seen there. ha ha. I just don't think I want oil vapors in my intake manifold either.

 
Rep Power: 811

well oil vapors are fine, and actually you need to have that hose connected to pass smog. I might try one of those breathers I see all over tho just for fun. I'm getting a K&N typhoon short ram in a couple weeks anyway. I still wanna find a solution to the tb heater thing. How did you get the bottom hose off?

 
Rep Power: 308

Dang. I just bought a brass pipe too. Looks like i'll be returning that.
How about using a larger rubber ruel hose and sticking the coolant hoses in each end? Then just use screw clamp rings to secure them together?

 
Rep Power: 374

You can use a brass splicer from lowes or home depot in the plumbing section. its part number a-290 3/8" splicer in a yellow top bag. just connect the inlet and the outlet and use some clamp rings to hold down the pipe.

or you can take the inlet pipe to the tb and connect it from the block to the radiator outlet...but, you need really small hands to get behind the engine.

so far, those are like the best 2 options.

 
Rep Power: 308

I'm trying to avoid metal connectors b/c of what gearbox said. I would use the 1 hose method but i can't fit my hand down the back while using pliers for the clamp.

 
Rep Power: 374

^ yeah same here. im stuck with the brass connector for a while i guess.

Dont use brass. two metals in a collant system is bad. Used to cause all kinds of problems in honda motocross bikes. napa has plastic conecters in their heater section although you might have to get them from the counter cause you will need the 3/8 size. remember heaters use hot coolant so the conecters wont melt or anything and the part is about $3

now for the bad news. Honda is way too smart for us. that big electrical plug and cylender shaped piece right behind the two fittings? its a solenoid valve. it turns off the coolant flow after the car warms up. I got bored so I looked it up on the parts computer at the dealer. If you notice, our cars have no choke plate, no enrichening circut, no additional fuel injectors. honda uses hot air to help the engine start cold but they knew enough to shut it off once the car gets warm. You might still get some heat transfering through just because the coolant is right there at the TB but its not dramatic

Did my TB heater today, I took my longer inlet hose and hooked it where the outlet hose connects back in then took my outlet hose and put both ends on the TB, also I adjusted the slack on my throttle, got an awesome response from doing both of these things, although getting the hose off behind the engine was a super big pain in the a*s, I managed to get it done. AWESOME mod, just hope it holds up in the winter here in PA. Let me know if you guys think I should change it back in the winter.

Does anyone that used a plastic splice have any feedback? melting?

 
Rep Power: 0

I don't know how my friend did he, he did at the Honda dealership on a lift. I think he went from the bottom like grabing the oil filter. Clean Job. By the way, I plugged my hiole in my AEM sri and ran the valve cover breather hose open, and it's a good feeling knowing only fresh air is coming in, feels good too. I wanna but a breather at the end of a piece of hose.

i've used a plastic splice, and it's awsome. there's no melting. but you have to cut the ends so there's a better flow of coolant.

this is what i got. a universal vacuum connector.

 
Rep Power: 374

damn it, so many opinions. ill see if i can find a tough plastic piece. pvc pipe would work, but youll never find a 3/8 connector.

i just used another peice of hose, then got drunk and walked around with the remainder singing "i got hose, in different area codes"
