I just posted a want ad on GP Superstore suggesting a group purchase for Alumitech Reproduction radiator/fan setups. If anyone is interested in a discount through a group purchase, please register(if you haven't already) and post an interest in being part. You can use my name to register(same as here, cobaltchev67) if you need a reference to complete registration like I had to with a member here. I'm looking to buy a setup in the next couple of weeks so a discount would be great....thanks!

Thanks for posting on our GPSuperStore.com. We can try something with Alumitech. But I also should let you know we have fantastic deals on radiator / dual fan set ups that include a much better fan and shroud set up then the Alumitech. For $850 we can do a unit like the one below in 2 different versions.

Before I go into details on our radiators, lets talk about transmission cooling. I am a big fan of using a external cooler and using 70 to 100 degree outside ambient temperature to cool the trans fluid then using a 200 degree radiator to try and cool the transmission. This just makes sense. However, there are many that insist on have a transmission cooling tank on the radiator.

I tell you all this because if we build the radiator with no trans cooler, we can use even bigger fans.

The radiators come 4 ways and are the same cost.

Radiator WITH trans cooler built in. Comes with dual 14" Spahl fans (3560CFM) in a FULL aluminum shroud, in a double pass design (double pass moves the fluid through the radiator 2 times per pass instead of once) which adds as much as 20 additional degrees of cooling in extreme situations, Complete kit is $850.

Radiator with NO built in trans cooler. Comes With dual 16" Spahl fans (4720CFM) in a FULL aluminum shroud, in a double pass design (double pass moves the fluid through the radiator 2 times per pass instead of once) which adds as much as 20 additional degrees of cooling in extreme situations, Complete kit is $850.

Double pass design puts both upper and lower hoses on the passenger side and requires a swivel water neck so the upper hose can go to the passenger side instead of the drivers side. If it were me, I would never use a crossflow (original style) radiator again. However someone insist we also build a crossflow style (conventional upper and lower hoses on opposing sides).

We also have a Prodigy Cool package for a additional $90 that includes a billet radiator cap, hook / relay kit and a temp sender switch to turn the fans on at 195 degrees and off at 165 degrees


Below is a picture of a Camaro radiator (Chevelle radiator looks just like it but without the flanges fon the side) the one in the picture is built for LS1 and has the steam line adapter in it. These are absolute show quality radiator packages and polished is also available for a additional cost.

I've never used your product, but how is your product much better than Alumitechs? Where are your radiator cores made? Not bashing you at all....but you made the statement yours are much better, I just want to know why you believe that to be true?

The radiators are most likely very equal. The fans and shroud set up we use are far superior, just look at them. Alumitech uses 11" fans on a partial shroud, we use 14" and 16" on a full coverage shroud. Its really apples and oranges.

We just started selling these in April of last year and sold 40 Camaro radiators to the Pro Touring crowd last year, and have 40 happy customers. We use them in all our builds in the shop in Florida in the heat. Most of our cars have A/C also and high horsepower and they keep up just fine in our Florida heat.

the photo looks like a Ron Davis unit or a copy of .
there's plenty of room in the market for both styles of rad ,there are numerous companies out there doing box form style tanks ,like what you have pictured , Alumitech brings to the customer a OEM style press formed tank radiator that is a (correct fit )...I get asked all the time is your unit better in cooling then be cool griffin and a host of others .. the answer to that question would be .. its about SQ inches of cooling surface and tube size .. if your comparing apples to apples the same size rad and tube size ...they will cool the same .

As far as a fully covered core with aluminum shroud and only 2 holes to push air threw this can cause back pressures at cruise speed ,the Spal design with the 12 rubber door flaps does allow air to pass threw when fans arent needed and does not build up back pressure in front of the rad at cruise .. this is the reason we do not build a aluminum shroud with only 2 holes for air to try to push threw .
This is something people need to be aware of When choosing a product .. it might be great for parade traffic .. but not at 60 mph ... we have seen these issues in the past .. runs cool in traffic , but down the road hi heat conditions .

As far as correct down flow configurations for 64 to 67 ..is what you have pictures of the style of replacement for those years as a cross flow conversion in box form tanks .. just wondering ,as I see many other vendors only offering a cross flow conversion also for 64 to 67 , and as the hoses and OEM fan shroud does not fit can be a issue for some people.

All and all ..its what's the customer is going for ..price ..style ..fit.. and function ..we can leave up to them ... personally I think our product speaks for it self here at the forum ..At last count over 500 T/C members have bought our units .. so there's no need for me to push , the past customer base sell's it for us based on results .

Hey Don, we have not had any cruising pressure issue with the big fans since so much of the radiator core is open due to the size of the fan. I have had the issue with other smaller fan / box shrouds in the past and agree 100% with you, that can be a issue. To be honest, most of our cars, the fans shut off on the highway (unless the A/C is on for condensor air circulation) as they are not needed unless it is blazing hot. Especilly if the trans cooler is not part of the radiator. Most of our cars really need the help at idle with A/C on, stuck in Power tour traffic, 100 degree heat sitting for hours to get into a venue, LOL!

Our radiators are obviously more tailored to a modified, high horsepower crowd. Your radiators look like awesome factory replacments and I think we should talk about us becoming a dealer for that segment of the market.

I will send you a Pm when im thinking about taking on more Dealers .


Thanks Don

After reading both of your very informative posts, I'm more unsure now than before:confused: I want a high horsepower model but I want it to be a direct fit/easy fit also. Another thing I have discussed with a family member is the discussion between cross flow and down flow....I need to do more reading on this. I'll do some thinking....

Heres what I did wanted a crossfow rad for my 64, needed minor work to fit and looks better than a squaretank rad IMO.

Cools engine with no trouble even the hotest summerday.

I remember selling you that unit ..your the first to take one of our camaro rads and do the mods in a 64 .. looks good .

but as we advertise things to be a correct fit .. I cant sell that unit as a cross flow conversion .. would rather have customer buy the correct hastle free install of the down flow rad
but nice work !! you may have given some pro mod guys the idea
Don

I agree, nice install....but I'm running a washer jar, power steering and don't want to cut my new battery tray or core support mounts:noway:. Still thinking about this....

Just placed my order with Don (Alumitech). How often do you get to have a half hour conversation about your particular project with the person who builds the product? I think I asked about 35 questions. That type of customer service is hard to find, thanks Don. I can't wait to get it installed :D.

now that is one fine looking setup, i'm very impressed with the quality and attention to detail, it says a lot for the construction..

Griffin makes a unit that cools better than either the prodigy or alumitech radiators, but you do need to slightly modify your radiator brackets to fit the larger core.

I got my Alumitech order from the UPS man on Thursday. Everything looks perfect. Thanks Don. Now I have to get to work.

LOL! Now that is a blanket statement! To cool any better then our dual 16" (4700 CFM) fan unit it must have some really special qualities!
