Heat tube for thermac system on headers?

I've got a set of ceramic coated 2055s(hooker shorties) and I was wondering if I could buy a heat tube for the thermac system that will fit on the header. THe cold is coming soon, and the faster my motor warms up the better.

Here's a picture of it. These came with the headers made by edelbrock.

The thermac will not allow your car to heat up any faster. They basically desinged that for the few cars that would see arctic temps where the fuel would not attomize at those temps. Within a few seconds your car is attomizing the fuel the same way as it did with of witout the thermac.

EDIT: Not to mention that you have an open element which renders your thermac useless even if you did have it.

I still have the stock air cleaner, but I do use an open element during the summer. In addition, that's not my car in the picture.

I do live in Wisconsin, and it does get below zero degrees F.

I believe it also prevents the throttle blades from sticking open.

Wisconsin is cold no doubt but you will not lock up the TBI unit. I would be more worried about corrosion in the throttle spring making your TBI unit stick. The thermac was desinged to make the fuel attomose faster in super cold temps. I mean like -50* and colder. My car has sat for weeks in -5* night and +5* day(Ohio) and has always started.

It's a Q-jet, but anyway

I remember my car warming up faster last year(when I had the stock exhaust manifolds) and I've heard stories of throttle blades sticking open overrevving the motor and blowing it.

Same idea for coolant running through the throttle body on a tpi motor.

Just to clarify, I noticed on your website it says your car has never seen a snowflake, while I will be driving mine every day.

Just because it has never seen a snowflake it does not mean the car has not been driven in the cold. I have to question why in the world you would want to drive a thirdgen with more than an inch or so of snow on the ground.

go to the junkyard and look for one off of a s-10 or a sonoma with the 4.3, it should fit, i know on my 4.3 sonoma that tube is pretty long and it looks like it will fit if you have the stock air cleaner..

i know in the 40* weather we are having right now it made a night and day dif. on my truck, ive had the lid flipped on the air cleaner and the thermac hose taken off for the summer, but a couple weeks ago i put the lid on the correct way and put the thermac tube back on ive noticed it warms up ALOT quicker

The main issue I would not want to drive in the winter would be salt. I'll wax the car next weekend hopefully, then put on 7 inch wheels with 215s in the back, and 235s in front. My mom drives the 90 Formula(In sig) with 235s all around in winter. As a 17 year old with a job, insurance is bad enough, not to mention gas prices. It's not a challenge to use it during the winter, its helpful to know what to do.

PhantomFE3, are you refering to the flexable thermac tube, because I need something that could go onto the header.

yep its a flexible tube that on my truck hooks runs from the exhaust manifold all the way to the bottom of the air cleaner spout, looks like a little mini drier vent tube, it looks pretty long and looks like you could stretch it out so i imagine it would fit, my camaro has the same thing except the one on my truck is about 3 times as long as my camaros, so if you could ****** one from a sonoma or s10 with the 4.3 i imagine it would be enough for what you need

I have the flexable tube, the one that looks like a mini dryer vent tube, but I need the piece so it can get heat from the header.

I cut the stock heat stove off the stock exhaust manifold, then just trimmed it down to fit my header tube with tin-snips and a Dremel. I drilled a couple of holes in it and some stainless hose clamps, then pop rivetted the hose clamps to the modified heat stove. At smog test time, I just wrap the hose clamps around my header tube, and hook up the foil tube to the aircleaner.
