It's just not ideal. Our pump is great in all ranges and most unerdrives are a compromise.

So MM what do I need to do to my car before my 2400 mile drive here to AZ and how should I get it ready for the 110+ days?

Keef

well that sucks, because I have that under drive pulley. Could you make the coolant pulley bigger too compensate?

Install a more efficient water pump...that's a GREAT start.

^^^lol, insulate the frosty AC pipe

do you have any flow charts that compare your pump to stock ?

If it has at least equal flow to the stock pump at low rpm then the underdrive pulley will work in my climate .

Use your windows as much as you can to get used to being really hot!
Switch to straight distilled water and a bottle of Water Wetter or something similar (to lube the pump seal and reduce corrosion) in the rad.
Change the oil.
Get a Chevron card - its a lot of gas to cross the country. I've done it a couple times and I'm pretty sure there is a building in the UAE named after me now.
Get an OEM sun shield for the windscreen.
Dark tint.

Use your windows as much as you can to get used to being really hot! Really.

I just took a leisurely trip to Tempe with two passengers and my coolant temps shot up to 240 before I knew it. I flipped off the A/C and kept the fans on high, so it went right back down, but that is a scary feeling.

That new Koyo radiator improved things at all ?

MM once I get here I'm going to need to get with you and do some **** to my car if you don't mind. I need to get my EDFC wires routed through my firewall and I am going to install the Fan Mod. Give me a call when you get a chance.

I have it, installed it myself, couldnt be happier.

You should get it , 340 shipped to my door, got it from ebay.

Need to install a Gauge to be sure, but Im leaving New York to Asia soon, so probably cant do it until I come back (Thats end of Aug)

It is with great pleasure that I'm able to announce our pumps will be available on Monday July 2nd. The official price is $235 plus S&H including a new gasket.

Let the cool motoring begin .

Awesome!
Still looking for hard data.

Mazmart

iTrader: (12)

I'm going to work with hard facts before the hard data. Our pump is the best design and execution available for these cars by a long shot. It's just another piece of the puzzle in terms of longevity improvements that one can do. I recommend fan mods from the various respected companies that offer them and better radiators definitely don't hurt either. When I make the claim that I'm making regarding design and execution I'm referring to the high helix design and the clearances between the impeller and it's body and between the impeller and the pump housing. This is the culmination of a lot of experience and research. Rick's been friends with one of the top cooling system men in the world for 20 plus years from their SAE afilliation. What has been applied here is strong science. The improvements in clearances are effective in the low speed ranges as well as the high (You can run underdrive if you have been and don't want to give it up), but the design of the impeller is really good at reducing cavitation in the way it gently releases the water vs the traditional style.

As was noted in the Evans write-up, this style also frees up horse power. We don't have a stock style motor on our dyno to illustrate this nor does Rick have time presently as he has more projects than he knows what to do with.

I will provide more specific data when we can for those who operate on numbers they can see and touch (The Doubting Thomases amongst us ). We may get a test car in the future. It's important to remember that our pumps are being run on some of the better RX8 race cars around. What I will not do at this time is claim "Our pump will make your car run xx amount cooler or produce xxx amount of power" like some dishonest companies may. The wise among you know what to do.

Here's our pump! Just open the package like it's Christmas time and install as if installing the original.

Here are the other reasons that Rick is so busy right now.

OK, Paul, I want to know what that 4 rotor goes in?

Brettus

iTrader: (2)

Paul - I'm really not a "Doubting thomas " but I do like some sort of an idea what the benefits are of something before I buy it.
I totally believe you that this pump is superior to stock . But I guess I'm looking for a reason why I would want one because the stock seems to be working OK for me .

MazdaManiac

iTrader: (3)

I, too, do not doubt the claims that the pump is superior.

However, just because something is "superior" doesn't mean it actually works better.

I'd like to see net temp results and delta.

rotarygod

That last picture is interesting. It looks like a 2 rotor peripheral port 13B (maybe? still working on that one) with a dry sump system, and slide throttles. Judging from the crank trigger, it looks like it's probably controlled by a Motec. It's also got a 1st gen motor mount setup. What class is this for? Is that intake and exhaust just a generic used on the test stand? If it's not, I can't figure out what they'd fit in.

One thing that stands out for me is the apparent lack of fuel injectors on the intake manifold. The only injectors I see (I could just be blind) are on the rotor housings on the intake side of the engine.

rotarygod

Drive your car around at 7000 rpm and then do it again with the new pump, observing engine temps. You'll see a difference.

just found this thread........ I must have been blind -_-

MAZUMAATO, does this come with directions? I know this was asked earlier in the thread, but I dont remember reading a response.

Mazmart

iTrader: (12)

Exactly like stock. Use the factory manual or take it to a shop that may have done several pumps including RX8s.

I see you are de-coding my Japanese, hmm

Paul.

Mazmart

iTrader: (12)

If the stock suits your needs I would stick with that. The people who will benefit from this part the most are those who do track days or race their cars with long straightaways where full throttle is being applied for extended periods of time and where the revs may consistantly exceed 7000. This need is increased when you have ambient temps higher than typical. If you think that these may describe your conditions then I would suggest that you acquire the 'best' in water pumps available.

It is our beleif that our pump will reduce the problems of the low speed high ambient temp when used in conjunction with better fan control but this is un-substantiated at this time.

Paul.
