Zero pressure should not be a factor.
The increased viscosity will be - but whether it is significant or not ... proof's in the pudding.

Andrew,
Did the tweaking and experimentation include playing with the number of tubes per inch, fins per inch, and coolant and air turbulator design?

Well razors go up to five blades, so it's pretty obvious where things are going...

Gathering that data would be prohibitively expensive, at least for us. We could have tripled or quadrupled the number of prototypes, played with different cores and changed all those variables, and done lab-grade testing to see what worked best, but we want to sell a $450 radiator, not a $700 radiator.

I'm not doubting that the Trackspeed rad is possibly the best of the new crop of rads.
Let me rephrase my Q - which variables did you play with to end up where you are?
And what tubes per inch and fins per inch are you at now?
Oh, and I noticed you have the NB version on the site - is it really available?
Lastly, how did your rad end up being the same weight as the 55 mm Koyo with water, despite being way thicker?
Cheers.

Having said that, the single row may not perform any better than a cheap eBay radiator, but it does weigh a bunch less (like 5lbs less than the double). I will say that we have a drawing done for the singles, and if there is some real demand we can have them made, but for now we want to focus on the dual-row.

It's partially water weight, partially just the heft of the Koyo. Our unit is heavier by 1lb because it's larger, but the endtanks are smaller since they don't have to run the full length of the radiator top and bottom. We carry 7lbs of water, the Koyo has to carry 8lbs. Not only do we crush the Koyo on CLTs, we do it with less water in the system.

Thanks.
BTW I don't see the logic of making another "me too" radiator that has the same performance as the cheapies.
Any thoughts why a dual row is better than a single row of the same total width?

It's just a theory, but it may have to do with pure surface area of cooling rows against the water in the cores. Aircooled engines follow the same idea - instead of trying to maximize airflow over the fins on the head, they simply include as many fins as they can. Surface area is hugely important, more than people might initially think.

I'm definitely planning to purchase one next week if they are available. I just sold my Koyo 55mm. I instruct at local Texas tracks and thinking of going FI. Either way I want the best cooling for the buck to help deal with the Texas heat.

We are still taking orders, but after recieving interest for a dozen units we ended up with one paid order. We are going to order stock on this item soon, so if you are interested get your order in ASAP.
