Zs-ondabrain Posted January 9, 2011 Share #25 Posted January 9, 2011 No shrouding needed on my Z. You don't even need the fans after 30 MPH. This new aluminum radiator cools no less than 25% more efficiantly than stock and my temp gauge rarely moves any higher than 180, if that.Shrouds are good though. just not on my Z.

steve91tt Posted January 9, 2011 Share #26 Posted January 9, 2011 Shrouds are good though. just not on my Z.The electrics have a small shroud built in and if you mount them flush with the radiator then the air that they move will flow directly through the core. Mechanical fans have a much larger air gap between the blades and the radiator. With this sort of setup there is more chance for air to be pulled in from the sides when the car is traveling at speeds less than 30 MPH. Link to comment Share on other sites More sharing options...
SSuspect Posted January 10, 2011 Share #27 Posted January 10, 2011 I've got a little bit different eBay setup... It is an aluminum 3 core with dual 12" fans from Monster Cooling. Each fan pulls 6 amps. I can't find the same one anymore, but here are links to a couple of similar units: eBay 3 core Radiator Link Another eBay Link The one I purchased fit PERFECTLY! I mounted it similar to Dave using rubber blocks and grommets. Fans are mounted with the plastic zip ties also. I bought a thermostat control unit from Summit and it comes on at about 185 degrees. I have not had the car on the road yet, but after running in the driveway for 30 mins, the fans kick on for a minute or so and it is right back down to 175-180. Seems to work great! No clearance issues with the pulley at all. We'll see how it does on the road, but there is no reason to assume that it will have any issues. I need to take a few more pics, but here are a few (old engine compartment and new)... Tim Link to comment Share on other sites More sharing options...
Zs-ondabrain Posted January 10, 2011 Share #28 Posted January 10, 2011 Actually, That's almost the exact set up I have. with the exception of 3 cores vs. my 2 core. Kicks on at 185 and drops it down to 175 very quickly.Same fans and radiator and I'll be damned if I can find it on eBay anymore. Everyone has 3 and 4 cores now. Yet my 2 core works friggin awesome. oh well, what ever eBay thinks we need....Beautiful engine bay Tim. What are you using for an overflow can? I went to the auto parts store and found Lawnmowerfuel line (Clear tubing) and I love it cause it shows that I have fluid and if I have air bubbles as well as if the fluid is moving either way.If you can't find the right overflow can, try the hot rod shops.I used 4) Chrome plated 3/8" long bolts for the water pump pulley. looks like you did too?Looks great.Dave Link to comment Share on other sites More sharing options...

Yours looks amazing too! Note: Your combo switches and HLH, PLH harnesses and Diff Mount are installed. Can't wait to actually put them to use! Here are a couple of additional "current" pics with nearly everything in place. Still need to tune everything up, but need to put in a better fuel pump first. The "replacement" RX7 pump is a POS! I just finished the R200 and rear disc conversion and just need to tighten everything up and bleed the brakes. In the process of stripping the body now. Dash is out and gauge install is in the works. Not sure what I will use for an overflow yet. I'll check the hot rod shops around here. Should be easy enough to find. I have most of the "bolt on" parts for the engine and engine compartment assembled with stainless allen head bolts. Looks very clean. I am looking at finally having this on the road in mid-late spring. I do have the LT1 and 4L60e ready to go... Decisions, decisions...

Zealous Posted March 1, 2011 Share #30 Posted March 1, 2011 Sorry to revive this thread just a few quick questions. Do these radiators work with the normal fan or are they just too thick?I also saw this great deal on an aluminium radiator and was wondering if anyone has ever bought from this place or has one of these radiators?http://www.genesisautoparts.com/product/all35098x7107aa.htmHas anyone purchased the MSA radiator? This is quite cheap especially with the CZCC discount and supports MSA that supports us. Is it the same as the champion type?http://www.thezstore.com/page/TZS/PROD/PCLC04/16-6964Just trying to do my homework before I push the buy button.

Zs-ondabrain Posted March 1, 2011 Share #31 Posted March 1, 2011 They work fine with the regular stock fan. I ran mine with the stock fan for months but went with the cool factor and better cooling Dual fan set-up. Still Plenty of clearance with the 2 core aluminum radiator.Hit the Buy button and get that car back together.Dave Link to comment Share on other sites More sharing options...
Zealous Posted March 2, 2011 Share #32 Posted March 2, 2011 Thanks Dave I pulled the trigger on an Ebay Champion radiator with a good warranty will let everyone here know when I get it, install it and test it out Link to comment Share on other sites More sharing options...
240zdave Posted March 2, 2011 Author Share #33 Posted March 2, 2011 The Thermal switch is the Probe style that goes Into the radiator via the upper hose and a small rubber wedge with a slot cut in it. THEY WORK AWESOME!!! I was able to sit in traffic for over 20 minutes, in 98 degree weather and the fans would kick on every once in a while and cooled it PDQ (Pretty Damn Quick)The gauge never mover past the middle line due to the fans doing a great job.Aluminum Radiator and fans $145 ?? (eBay, seller in CA.)Thermal switch $30 (Napa in Marysville, WA.)Some power wire, inline fuse and a relay $7 (My own stock)2.5" x 10" Polished Aluminum overflow Can ($50 @ Dreamers Hot Rod Shop in Everett, WA.)Total of $232 before tax. Best cooling system I ever owned.DaveDave, do you remember the P/N for the thermal switch? Link to comment Share on other sites More sharing options...
bpilati Posted March 2, 2011 Share #34 Posted March 2, 2011 A local radiator shop can also take your stock Z radiator and replace the core portion with a version with more rows. Link to comment Share on other sites More sharing options...
Zs-ondabrain Posted March 2, 2011 Share #35 Posted March 2, 2011 Nope, It was bought from NAPA and was about $30. Came with the copper line going to a 3" probe, a black rubber piece to help seal the copper line thru the rubber on the inlet. and the line is attached to a Dial Thermastat. Post #13 picture #2 I wish I wrote down the p/n. You're not the first to ask. Similar to this....... Also this could work.... http://www.summitracing.com/parts/DER-16720/?rtype=10 Or this...... http://www.summitracing.com/parts/DER-16769/ This one is Real close to what I have, but has a smaller dial knob and costs more. http://www.streamlineus.com/ShowItem/125450%20Adjustable%20Temperature%20Control%20Switch.aspx Or this one... p/n PWI30104 half way down the page.. you'll also need a relay kit for the switch to turn on the fan. http://www.rjays.com/Cooling/elec-fans-01.htm Link to comment Share on other sites More sharing options...
