Starting gathering parts for the cooling system overhaul I'm doing to my drift car atm. I'm ditching the clutch fan set up mainly due to the fact I just don't have the room to fit all the parts required with out trimming something to make it fit.

Now I plan on running a tabata alloy core with an alloy shroud made up to space thermo and mount then too.am I beyer off running one large 16 inch spal fan in pull configuration or two 12 inch spal fans side by side also in pull mode?

I also plan on running a header/swirl put set up. Does any one have a diagram to correctly hook this up and what radiator cap I should be using on both the header tank and the rad itself?

Hey bud in regards to the twin 12" or single 16" question. The twin 12's will cover more surface area if you do the maths. Twin 12's cover 226.08 square inches, whilst the single 16 covers 200.96 square inches.

Running with this. If you can fit a single 18" it covers 254.34 square inches. Which would be the better of the 3.

Personally if you can fit the single 18" i'd be going with that. Simplicity is always better :) Hope this helps :)

Id set it up on a 2 speed switch thing, so when its under temp it just slowly makes a breeze so you have a little airflow plus it uses hardly any current on low speed and will be quiet. Unsure if you need a special fan for low speed but with dc power i dont think so?? Thats just what id do thumbsup.gif

Simon, Im upgrading my twin 12inch Ebay fans to one 16inch Spal fan.

Make sure you get the 3000cfm one. Its a bit exxy but its well worth the money.

As for the header tank setup, just use a blanking cap for the radiator and a Nismo cap on the header tank.

Has anybody looked at venting the head water jackets in order to reduce localized boiling above the exhaust side of the chamber? I've tuned a high comp ls1 with this method of cooling and we were able to get the timing back up to around 22degrees (from16-17) and we gained about 25rwkw. It must be a problem with the length of the rb blocks.

The other gain is a lower coolant pressure which May reduce pumping losses.

would anyone see a problem with doing away with the rad cap on the radiator all together? for one its not going to be needed and secondly i can weld a nipple on the top tank in an elevated spot for the feed to the swirl pot anyway.

Simon, I intend on using a swirl pot as well, but I'll keep the radiator cap on the radiator for ease of filling most of the system as well as having a cap on the pot.

In this method, apparently the cap on the pot is to be of slightly higher release pressure than the rad cap.

Has anyone tried these ones from eBay?? they're stupidly cheap for 2750cfm! That could mean they aren't that great but much cheaper than the SPAL one to at least try.

NOTE: I see that the SPAL 16" Extreme one has the following warnings, not sure about the ebay one?

"The fan motor is not sealed and should not be used in the following conditions. 1. High dust, dirt, and/or wet environments. 2. Unusually high ambient temperatures (exceeding 176 degrees F). 3. extended/continuous modes of operation exceeding one hour in duration."

Maybe even 2x 12" ones as it appears they are rated to 1650cfm each. Seems to be basically the same as the rating of the SPAL 12" High Performance.

Don't know, that's what I'm asking.. hell, I may even consider using one if they are any good :) Might even be worth it for replacing the A/C one on the front?

I just had a very quick search but couldn't see any reviews..

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
