Where to run the hoses Options

[tyler]

I searched around alot trying to find the best radiator and was almost going with a new 944 aluminum one by the "questionable" guy on Ebay. But found the Griffin 27 1/2" x 15 1/2" aluminum racing radiator - 2 rows of 1" tubes. This fits perfect, heightwise. So far it seems to cool great, that's probably why I can get away with pushers (2400cfm) and only normally run one of them. I'm still waiting to hear from Griffin about the "seepage".

Cost was about $275

nice setup tyler (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) would it be possible to see a pic of the front of ur car i am yet to cut my hole in the front ?

i also used my spare bonnet to cut the hole in the top just incase it was a disaster i saw it done on a race car over there and thought the downforce would be nice to have (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif)

the bonnet still shuts with all this in there also

As soon as I get the radiator back and in I'll post a good set of pics. I have to be able to get it out in the sun. I'm in the process of mounting the inflatable spare against the fuel tank bulkhead while I'm waiting fot the radiator to be returned.

I didnt know Griffin made a dual pass radiator. Was it pricey? I am interested to know how well it works. Mark

Griffin 27 1/2 x 15 1/2 radiator with two rows of 1" tubing for $189.95 from Summit Racing. I bought the Griffin 27 1/2 x 15 1/2 radiator with two rows of 1 1/4" tubing for $259.95 from Summit. I wanted to be doubly sure I didn't have any cooling problems. (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif)

I believe that's a dual core radiator, vs. a dual pass. A dual pass flows to one end then back, so the inlet and outlet are on the same side of the radiator.

Guy,

Thanks for the clarification. Is there a cooling advantage to the dual pass style? I believe that is the style (dual pass) that Renegade uses?

Thanks,

Don, supposedly they are more efficient. How much so I do not know and I have not seen actual data to support that claim.

Don,
Can you tell us where you found the fan set-up and shroud on your system ?

TIA

dakotaewing,

I bought the fan and shrowd setup from Summit Racing (http://www.summitracing.com). They are made by Flex-a-lite and are their model #FLX-310. Cost was $219.88 plus shipping. The fan came with everything needed for installation to a radiator including an adjustable thermostat. You can buy the same set of fans/shrowd minus the adjustable thermostat for $189.88 (model # FLX-320), also from Summit. I liked the idea of an adjustable thermostat so spent the extra for it. The whole kit seems quite well built and was easy to install.

I hope that helps.

dakotaewing,

Here's another picture of the fans/shrowd from a different angle.

I helped a friend on his V8 914. He used braided stainless steel rubber hydraulic lines. He was also using the depressions under the car. It had the strength and would handle a couple of hits under the car.

Don -
Thanks for the details - I spent quite a bit of tme last night looking on summits website at all the different radiators and fan setups... Some of the dual fan setups are stated to have a 50 amp draw! Anyone using one of those better have a good altenator!!

Thanks again -
Thom

Tyler -
Do you happen to have the model # on your radiator? From the pics it looks as if your radiator does not have a cap, similar to the Ron Davis units built for renegade... Please elaberate on why you are using the pushers instead of the pullers, and let us know how many miles you have on this system -

Thanks -
Thom

I didn't see a model number on their site but I'll take a look at my reciept tonight. Griffin furnished it with 1-1/4 & 1" conns (same as the hose), also a bungs for a drain, temp switch and vent (at the top). I don't know why there should be a fill cap when the fill really belongs at the high point where the hose comes from the tstat at the engine. The vent conn on the radiator works fine for the initial fill and if you use the filler tank from RH with an expansion tank, air in the system will always bleed out. Also my radiator would never have fit with that fill cap. The one in the other picture must not be the exact same size as mine. I have a set of pullers (from a 944, with shroud) and they worked great but I wanted to save space (for spare tire) so I tried those cheap (~$75ea) pushers and they seem to work fine. My mistake was that I should have gotten a second bung on the radiator so I could have the second fan come on automatically at a much higher temp instead of manual, but I never expected one fan to do the job. I'm still working on the system so it's new but I've run it on 90 degree days for ~60+ freeway miles + traffic stop and go and it never gets above 195. There's been some talk about the temp gage fluctuations (including from me) and I found that the temp does bounce back and forth with the tstat opening and closing until the whole system/engine gets up to temp then it's real steady. I was worried about blocking air with the pushers but they never even come on on the freeway so the radiator must be good.

I was getting temperature gauge variations in the first 15 min. or so until I moved the sender from the head to the top of the intake. That's helped a lot to buffer some of the changes during engine warmup.

I got my dual row, dual pass radiator (pic below) with cap delete from AFCO, #10133N. The dual pass costs a little more than the single pass. Their single pass is the same price as Summits'. AFCO is also a good source for spings and misc racing stuff with very reasonable prices, IMO. They manufacture most of their products.

Oops, sorry for the jumbo sized pic!!!

Tyler,

My radiator is the same size as yours but it is installed at an angle so the fill cap clears fine. If I had tried to install it straight up I don't think it wouldn't have cleared the hood. In this picture you can better see the angle of installation.

Tyler -
Did you order your radiator directly fom Griffin? I did not even check to see if they had a web site, I was too busy looking on Summits and JEGS sites....
