HEAT SOAK LET'S TALK TECH

[@rotaxtwin]

Long time ago I ran a Radio Shack outdoor thermometer from in the cab to inside the airbox on my Ranger. It was pretty quick to respond to temp changes, it would go from underhood temp to outdoor temp as soon as you stepped into it. You could see the temp drop as the cruise stepped into it to climb a hill. I had done a swiss cheese job on the airbox with a small hole saw.

Speaking of heat soak, the intercooler in my Jetta TDI used to heat soak like crazy in stop-n-go traffic, especially in summer (I'm in Florida). When the intake temps reached 80*C or so, the engine got unhappy. The Jetta has a small side-mount intercooler. So I put a 7" fan on it, with a thermal switch. No more heat soak! Intake temps never go above 50*C. It makes me wonder why intercooler fans aren't more common.

Glad to see the fire didn't get to you buddy stay safe have a great night and weekend everyone ❤ y'all later

Interchiller system have an option of a “race” solenoid to isolate the intercooler circuit from the cabin AC for when at the drag strip. This is so you can race at the track and not drip water from your cabin AC. As you mentioned these systems will not keep up with sustained power runs around a circuit etc, but a larger reservoir of chilled water can be added to help somewhat. That adds weight though so really just depends what your goals are.

Heck yeah, I'm totally excited for this test! I just switch from plastic tube with open element filter to aluminum tube with filter box and ram air. I know it's better but data would be awesome.

Picture with flame awesome!!!

interesting topic.

Hello, can you share the specs of the valve springs used on the camp swap for the 8.1 BBC? Great videos

[@L_S73]

Ya.... but they got what they voted for... most of the...😂😂😂

I think the duration is so damn short for the air contacting the inside walls of the air inlet ducting that it won't make much of a difference, especially at wot when the air is really ripping through there. I do believe drawing air in from anywhere aside from under the hood is beneficial, but then you have to probably factor in restrictions.

Just saying "smoky unick" did it in the 80's with a turbo and a carb.

Heat soak is not a myth... We run a Cal.Air induction boxed air filter and tube and a NW103mm, The supercharger is 1.9 LSA Eaton with 2.55 and 9.17 pulleys, AFCO twin fan and re-enforced brick. If you drive it in 90 degree heat and then compare to 50 degree you certainly can tell the difference in performance. In 90 degree while moving it will stay at normal operating temps. I suppose the heat extractor hood helps some but I loath to drive in the city. Put a bigger transmission cooler with fan as well. Heat is not my friend! BTW gas costs $2.75 regular and last time I bought E85 it was $1.89 been that price for quite a while. If they are buying drums of VP fuel and want to misrepresent that they are buying pump gas as they did then we know they are full of it!

You explanation basically says that drawing in colder air helps power-that is not the same as heat soak

[@ragtopdeluxezl1]

@@richardholdener1727 Actually I was talking about heat under the hood and drawing down the heat, I see too why you said that, but was not the main point. I am getting heat soak under the hood with the blower and transmission adding heat to that of the engine. when at a stop sign I get higher temps and when I stop for gas the temps rise while gassing up. The 50 to 90 degree ambient temps I refer to is how much heat the engine retains and how it performs in those conditions.

Haven't seen a lot of ring ridge since unleaded gas took over. Nowvyou know how old I am. Back in the day before cool suits, racers were men.

Are you still stepping on floor dimmer

I'm still stepping on the floor dimmer lol
