I met a guy here in SoCal on another board I am a member of who recently started making radiators. He has an engineering background, and abilities to make radiators, and has a passion for cars. He is in the middle of a 25.3 build Buick Grand National, so that is the first platform he made a rad for. I have one of his radiators in my GN and it is amazing. I got a powdercoated one from him, to which a lot of guys said the coating would be a detriment, but it is working amazingly well. He has made other radiators for other cars like Pony Mustangs, etc and I started asking him about making radiators for the V's. Main reason I asked is I am not really super comfortable with how hot it runs currently, and mine seeps a little between the aluminum core and the plastic end tanks (or top/ bottom tanks in this case).

My question is, what would you change or what features would you like to add if you could design a rad for your V? He makes rad's for the GN's with no coolers, an oil cooler, or oil and trans coolers. They are really amazing. I would like to run an external oil cooler being here in Sunny SoCal, so not sure if I would do an internal or external, but I am considering an internal, since the one in the GN works so well.

I know we are limited on space both width-wise and length/height-wise, but may be able to squeeze another 1/2-1" more of core width. Let me know what you guys think, what you would like to see made, etc. I am all ears and will pass all info to the builder to see what he can do.

Here are a few pics of the one in the GN as an example.

Not that I am aware of. Here is his site/ company name:

http://www.alradco.com/

Like I said, just a modest guy who just decided to make stuff to support the hobby, and rad's is one of the things he saw a need for. I know in the Grand National world we have the F Body rad as a popular swap, but with the plastic end tanks sometimes they seep or don't hold up well, and are made in China usually. Then you have the BeCool, which is rather pricey. (~$800+ from what I have seen) He decided to make one for his car, then it has kinda started growing.

Will do, Gary. You have any suggestions on how to improve these cars' radiators? I know you have a lot of knowledge, I haven't had the car too long... Haven't broken it yet, so it has feared better than when I first got the GN. ;)

Personally I think how hot the car runs really isn't because of the radiator. Its how the fans are tuned and the thermostat that is in the car. I know guys like me would love to have a better radiator but with the maggie HEX and the 8 rib pulleys, I cant really go any bigger than the stock radiator. I know there aren't too many 8 rib guys so that point may be moot to everybody else but it sucks for us! lol

Sorry, James, you evidently have me confused with somebody else. No knowledge here.

I wonder if he can stick with the same size as the stocker, but maybe a better fin per inch design or something...

I would like to suggest a radiator that isn't much thicker than stock, yet uses tanks that take advantage of available space. It appears that the tanks could be a little larger. The core could be a bit thicker, and optimize the numbers of fins per square inch. I've read a couple threads indicating that an integrated oil cooler is too tight a fit. The Ron Davis integrated oil cooler has caused issues with some users. I would not reduce the size of the coolant system for the sake of an integrated oil cooler. The current V radiator is as small as GM could make it.

Good info, much appreciated. I think the plan is to take pics of the rad installed from every direction to see how much room there is (or isn't) on each end and side, and see if we'd be able to sneak a half inch in length on each end, and maybe height, then concentrate on a more efficient core design with more fins per inch, etc.

Thanks again for the info, I am all ears here for any more suggestions!

I would go for a radiator designed with clearance for a cold air intake as pictured.
If N/A guys didn't have to worry about air intake tubing clearance with the p/s pulley, there would be plenty of room for thicker radiator.

Hmmm... Peter had mentioned that about trying to make room for an intake like that, but that pic helps the idea quite a bit. So, you could possibly make the core taller (if clearance allows), with a "U" channel for a cold air intake. Do you have any more pics of that setup? I am curious what the rest of that intake looks like? A cone out front? Flat panel scoop with K&N?

Thanks a bunch for the reply. Like I said, any input is greatly appreciated!

Really can't go much taller. I was thinking of a thicker or deeper radiator core/tank. I will get some rough dimensions. Still need room for the fans and ABS controller module.

I will see if more pictures are available. The hood latch/release would be gone as in the picture. Note the hood pins.
Air intake could be similar to the vette's, single or dual cone, whatever your air flow needs are. I just like the benefit of colder air.

Hmmm... That kinda sucks about the stock hood latch. I am not so sure about drilling into my hood yet. :bonkers:

What I will prob do is after taking a gang of pics as it is now, tape some 1/4" and/or 1/2" foam insulation or something to the tanks where we have the extra room. Build it up in a way so he can see how much we could expand in all directions. I would assume even adding to the tanks themselves, if enough volume, would aid in cooling. (more capacity = more cooling?) Add to that a better fin per inch count or another row altogether, this thing could be awesome... I am trying to picture if there is any room widening it to the front of the car... I need some more garage time.... :bouncy:

Well, the rad designer has my V rad and a gang of pics and measurements to see about fabbing one up. He has it in design/engineering, and once it is completed I will be testing the first V rad made by him. I am excited! We talked about how to proceed with options, like the U in the top to make room for an intake, but are contemplating exactly how to approach it. I said some guys who don't have the need for the U might not want it, wanting more to stay mostly stock in appearance, but you never know. If they were all made to clear an intake later, it would not limit you for future upgrades. I know if you are like me you say "I will never need that", then get bitten by the mod bug...

We shall see, I will report more as I know it, but it looks like another aluminum radiator, which is MADE IN THE USA!!!, and is very close to stock appearing, will be available to us.

I like this idea a lot, except for the hood latch part. I was looking at it the other day wondering if i could lean the rad back a little to run an intake pipe down in front of it.... i cant wait to see the results either way.....

Well, talked to the guy who is building the radiator and he said it shouldn't be more than a few more weeks. Man, I am chomping at the bit to see it and get it in!

Well, as promised here is the radiator Peter from ALRADCO made. These are his pics, and the rad is in the mail to me right now. I will post a ton more pics when I get it here, and will do an install/how to thread with comparisons and details. I think it turned out awesome! I can't wait to see it in person!

After seeing the detail, welds, etc I wondered if he was going to be able to keep it affordable. Like with the Grand National radiators, he is not asking a ton trying to make a ton of money. He is trying to do something good for the hobby and give everyone something we can enjoy. The price???? Under $500! I am sure he could ask more, but he feels there is no reason to rake guys over the coals.

Take a peek, let me know if you have any questions, and stay tuned for the install/comparison thread!!!

James

EDIT: There is a reason for the Red, White, and Blue in the background. Peter's radiators are AMERICAN made!

Quick update with some pics I took of the rad today. Was a little rushed so they are not the best. Will get better ones during the install process, hopefully tomorrow. I am very impressed with the workmanship on this thing. The welds are really nice, the radiator hose necks are super thick, it is now a two core, vice a single core like the stocker, it is wider, but not overly wide, and the places where you thread a nut into are helicoiled. That will make it nice where you won't spin the threads out the first time you bolt it in and get a little aggressive... He plans to offer it black powder coated as well, if you prefer the semi-stock look.

Yeah, that is what I thought! I am very impressed with it. And, knowing how well the other one works in my Grand National that he made, I am anxious to get it in. It is crazy about his radiators, I almost just want to hang them in the garage and stare at them. I have a thing for nice welds, quality workmanship, and also love it when someone identifies a need and says "sure, let's make one", like it is as easy as changing your oil. Oh, and made in the USA (Cali no less) gets big points in my book. I know it is cheaper to get stuff made in China, but the quality control is usually hit and miss. This thing is all around great in my book.

That is pretty interesting! I like how he did that, will have to search his username for info/pics. That makes a lot of sense.

Yeah, I have to agree it is much better than stock. This thing should last forever. Mine seeps, but man that pic you have is pretty bad! I will start another install thread after I get it in and get all the pics laid out. I want to be able to compare before and after, that is important to me. I will post up everything I can about this beast, and keep updating as I drive it more, and put it through more tests. I will also let you guys know once testing is done, and when Peter gets everything online for selling these, and if there are going to be options like the "U" channel on the top for CAI.

Now that I looked at mine more closely, mine leaks in a few spots, almost as bad as yours, shady!
