Was the shroud a custom deal or does someone sell something for that?

Pics of radiator setup? In just looking at stock fan setup it looks like typical setup to keep car cool in traffic but hamper higher speed cooling. Boxsters have same issue.

Well CSF's radiators are commonly available as upgrades. There was also this on the boards, some guy modding the stock core support to put in a super-thick racing radiator from GTM, and re-using the stock fans with a slimmer metal shroud that might work better:

In 2-3 months I'm planning to go after this area of the car as one long project. Remove my stock radiator, delete the AC/heat stuff, maybe upgrade motor mounts and check up on my header bolts while it's all easy-access. Then put back in at least a bigger radiator, but possibly w/ a Laminova unit replacing my separate air coolers as well. I just wish I had a firm grasp on how much radiator + Laminova I need.

I'm planning to use it to cool tranny fluid from the 7AT as well using one of their dual-core models with separate inputs.

Quoting myself, but just to clarify I'm wondering what you mean by shrouding, do you just mean a fan shroud on the rear of the radiator?
I saw that GTM makes a upgraded dual 14" fan kit for stock radiator.

Or did you also make some kind of shrouding in front block air from going around the sides,top,bottom, and force it through the core?

Here's a video... if you check this tonight, prob need to wait until it finishes processing on youtube's servers...



Should give you a better idea of what a fully enclosed radiator/IC looks like. Full shrouding in front and back of those units. The laminova unit, you can see it behind the radiator sitting atop of my splitter... the laminova unit is mounted along a large aluminum piece which itself acts as an additional heat sink / dissapation point, which was a pretty trick move by the guys at CIN motorsports in Charlotte... they put a lot of time into this shroud and setup and gave me a great deal!

I didn't research the GTM kit, but I'm guessing the package they have will ultimately cost you less if you DIY the install vs going full custom like I did

Not enough data to report on what size laminova unit at this point, I went big / dual core... I do recommend stuffing in a thick radiator replacement if you're going to delete a/c and redo the cooling and the shrouding is a BIG DEAL... also there's a setting in the nissan computer for when the fan's kick in... have your tuner play with that so both kick in at 190-200... if you get energy efficient fans, should be able to run stock harness no problem

I called BAT inc yesterday and spoke to one of the guys who seems to think a 43x330mm core would suffice, at least for my application (naturally aspirated). He actually originally recommended the 180mm length one, which he says would be similar to a 19row cooler. But I told him a lot of people are running 25 or 34 rows, so I will probably get 330mm for piece of mind. Still really expensive for even these smaller cores. I think the price went up about $100 since when I first looked at these over a year ago. :mad:

43x330 should be plenty! look forward to hearing about your progress/testing

must nice to be an exclusive distributor, huh? lol

Not sure how much those Laminova's are going for but you can pick up a C&R Cooler for under $500:

Or if you haven't swapped radiators yet, they do a radiator with the oil cooler built in like these:

^thx for posting... the combined unit looks like a good idea for our car, cleans things up and saves space for whatever else...

laminova claim to fame is no pressure loss across the unit, which is nice to have on our cars given the relatively high oil flow rate... wonder how the C&R units are on that dimension?

Heat rejection and pressure drop figures are in the bottom left corner of the dimensions pdf here:

http://www.crracing.com/wp-content/u...er_diagram.pdf

In general L/L heat exchangers are more efficient and have lower pressure drop than a comparably sized A/L core. They claim that the L/L cores they build into the radiators have even lower pressure drops than the remote mount units.

Helpful data thanks... maybe someone more technical than myself can come in here and explain the benefits of ~0 psi pressure drop vs ~2 psi pressure drop... does it really matter?

Also curious which setup among the three saves the most weight... seems like combined radiator/cooler design should be the most weight efficient

That was the right belt... but replacing it this weekend, I'm simply amazed that the last guy was able to get this belt on... with the tensioner all the way, I'm still an inch or two short of getting the belt over the pulleys. I'm going to try switching to this one size up... for random passerby's please keep in mind that this only applies if you have deleted your a/c and added a GTM supercharger kit

^ I was just a hair short due to the lip on one of the pullies. I had to remove the pulley and carefull retighten the pulley bolt without stripping due to the slight pressure on it. Worked fine.

Good for you, unfortunately mine's just too far... I think that's why my car has been squeaking - belt was tight beyond the limit of the tensioner... 2 inches more should do it

....nah, never mind...
