Thread: battling heat soak

Im working on installing a digital coolant temp guage in place of factory cluster gauge within the next week.

Ive been trying to get a hold of/borrow a laptop to datalog with, because the battery for my laptop died several years ago. and its been a wall outlet laptop for a long time.... Unless someone has a converter i can use in my cigarette lighter?

That sounds like a fun experiment, and Im willing, just need something to datalog with.

Go to RadioShack and get a Power Inverter. I run one in my car for my laptop so it can stay charged. Mine was $40 and it has a power plug like you would find at home, a usb plug and a ciggarette lighter all in one. I can run my GPS, radar detector, charge my phone and run my laptop off it all at once.

$20 at Walmart for Power plug and USB plug. That's all you need honestly.

If you want to run the GPS at the same time, get a Y splitter for $5 while you are at Walmart too.

Not saying he had to spend that much, just was saying what I had and what I spent.

that will run a 3 amp laptop charger?

im looking for one of the on their website...

Ok this thread is all over the place,there are too many people throwing ideas that don't apply. The problem is being mis-diagnosed. Why would heat soaking cause hiccups? What exactly do you mean by hiccups? What temps is your oil or coolant at when all of this is happening? This really sounds like a tuning/sensor problem going in the wrong direction as already said.

But on the note of heat soak your intercooler pipe is in a bad location, running over the exhaust mani like it is. Aluminum absorbs heat bad enough as is with out sitting over a hot plate (the mani) like it is. Re route that shit, take a look at how so other guys are doing it with less pipe that doesn't run over the manifold. With as much pipe as you have you won't have to buy any more. Your problem is not the heat from the radiator as much as is it is the manifold (among other things) if that is even is the case.

I'll reply like you are talking to me because I'm not sure if you are talking to me or Vadim.

Radio Shack doesn't list it on their site. Check it out in the store. I posted a pic of the exact one I got if that helps. Its a 150w. I got it like 2-3 months ago so I am assuming they still have something like it?

ok Thanks.

Aluminum displaces and absorbs heat more than steel, not necessarily a good thing if it is by a heat source. Steel would absorb and displace less heat over that exhaust manifold. So the fluid inside steel pipe is less affected in a steel pipe.

Wrapping pipe only helps keep the intake temps cooler if the pipe is next to a heat source. There is no reason to wrap the intake manifold in most cases. The air is already really hot from that pipe that runs over the exhaust mani. Wrapping the pipe after it has been heated just keeps the heat in the pipe.

Dont have a coolant temp guage installed yet.
Or know the oil temp.

Id think that adjusting the tune would fix it.
When my car was dyno tuned, it was 50F outside & with the hood open.
But im sure the heat soaking wasnt accounted for in the tune, and when (i assume) the intake temps get 200F or maybe more, that will cause the hiccups(probably detonation) im getting until ive been rolling a min or two for some airflow.
