Cooling issues? Not anymore

Best of both worlds! Old and new, love it
Off topic- I’m building an old school Chevy too. Just got this in.Hopefully an ex-Gm engineer can tell what it is
Clue: Z28

 

ls7. good grab is thats a great create motor. in 2018 they made the last 500 ls7s that would ever be factory made. whats it going in?

 

Here are some pictures of what's going down with mine

 

@Deo taco following this. Living in high country AZ. When it’s been warm and slow and go climbing some trails. I’ve had the temps rise on me while in 4low and higher rpms. I’d hear the fan spool up and down.
But I’m interested in how it does in the winter with road slush. Possibly freezing the fan in place.
Been a few times where friends running led head lights freeze over while my halogens can keep the heat and ice off my headlights clear.

 

freezing the is not an issue. modern cars fans dont freeze in place. im not making the fan, im making a kit to take a oem fan work in the tacoma.

 

I think I got the P/N

 

When we raced we used 0 antifreeze since it would cause an issue with drawing heat off the metal (surface tension maybe) but some of the engineers from royal purple discussed it with us.

 

71-72

 

Anyone have experience with engineice?

Just use Pink/SLLC or an equivalent. Want it to be high performance, in terms of heat capacity? Mix water to the above discussed ratios. 80/20 will actually take freeze protection down to about 17F. It will require changing more often, as the concentration of everything will be reduced, and thus the corrosion protection.

 

Great little blog on coolant https://hellafunctional.com/?p=629

So if the stock system is 11qt @ 50/50 And we wanna get to 11qt 80/20 we could drain approximately....3 uh....maybe like? 4 uhmmm.... Fuck it, drain it all and start over.

 

use distilled water as well, if it wasn’t already obvious. When you drain the radiator you’ll get about 2.5qt of coolant out of it.

 

That's not actually true. Regular tap water is fine as long as you don't have extremely high mineral content, then just filter it so it isn't as heavy deposited. Here is one link I can pull up more, at one point in the late 90s early 2000s almost every vehicle manufacturer had a TSB regarding not using distilled water.

This is correct !!!!!

I've used tap water for many years with no issues

 

One of the original issues especially with the aluminum radiators was internal blockages due to the push for everyone to use distilled water. I'm surprised that's even a thing anymore since it got debunked so long ago

 

Somebody is MAD they can't afford/don't want to buy this fan. Sorry bro, but you gotta live and let live. Kinda coming off like a troll

 

I feel this, but with that being said at 800-1000 I could stomach it based one factor not mentioned @Deo taco, that being dyno HP and TQ numbers as well as MPG improvements. As long as you do an apples to apples MPG comparison on a dyno I would be good with that. If the MPG improvement is significant enough the mod pays for itself, and the added smiles per gallon that legit numbers bring would have made it worth it by itself so it would be an absolute no brainer for me and I think a lot of others at that point. Real data would go an awful long way, even in comparison to data from Engine Masters. I trust them for many things, but they are still working with most likely a big American V8. There are a lot of variables there which would change using a V6. Honestly, it would probably work out in your favor there and might show even more dramatic improvements percentage-wise, because the V6 is smaller and lighter so would have less rotating mass with which to spin the fan. Either way, I am very interested based on the obvious quality of your work here and your knowledge in general. Don't let the keyboard cowboys get to you man you're doing this the right way IMO

 

65 Malibu(wife’s car). I was sooo close to getting the LT as I really wanted some boost. But something about a large displacement, All motor with a choppy cam in a muscle car is made to be. It’s actually a new crate GM released last month. A reworked LS7 that the factory converted to a wet sump, Ported heads, cam, etc. Good for 570hp and still the factory warranty...I can’t complain. If I get a wild hair I can always boost later.
That build looks nuts. I see the Z06 carbon ceramics on there... that’s my next purchase. Looks awesome!
