Yes...not a JR company project.

OSCAR Jackson Senior... told me at Laguna event that he was helping on the CARB, and he just happens to have a ranch in Colorado.

Fender flares not installed yet...but this is the most it has looked like a real 'regular' car in a few years...

Still such a badass Miata!

We added a serious front lip to the MazdaSpeed nose for some decent downforce.

Heat Exchanger Replacement and Upgrade!

The heat exchanger included in the kit was oversized already for 99% of customers. I know that posting this upgrade will mean that customers just driving the car back and forth to work will start calling me to ask how much benefit they would get with this upgrade...BUT PLEASE READ ME LITERALLY HERE, YOU DO NOT NEED IT.

Our car here is exceptional, it uses a much smaller 2.7 pulley and it has much more aerodynamic drag because of the big fender flares used to cover the monster wheels and tires used for autocross events. And we visit HOT tracks with LONG straights. The result is that, unlike most all the customers I know for this kit, we put enough constant load that when not using meth/water injection we heat soak the intercooler and cause a steady rise in coolant temp that keeps rising with each lap at tracks that require LONG...LONG.....LONG...applications of boost. Best example here in California is Auto Club Speedway....where the front NASCAR straight can mean about 30 seconds of constant boost! After three laps we watched the temperature climb and climb. Most customers are never going to put this kind of load on the system, but we do. However, now and then a customer calls to report they busted the heat exchanger included in the kit in a fender bender, or from a big rocking coming through the nose, and they need a replacement. Similarly, we both need a bit more cooling because of our exceptional use....AND our car got backed into at an SCCA event and my original exchanger is bent and twisted.

So, if like me you need to replace it anyway, and could perhaps use the upgrade, here is a very interesting option. After hunting and hunting around we found this unit ..and it is a near perfect match in measurements for our original unit.... except it is double the core thickness. We are working on the brackets so we can offer a plug and play kit, should be on our site by sometime in May 2016.

Picture on top of BOTH pictures below is the original kit heat exchanger next to the upgrade double thick replacement. Notice that in terms of configuration they look like twins with hookups on the same side and same location so you don't need to re-route hoses! New unit is 2 inch core instead of 1 inch core original, so about DOUBLE the capacity of the original. I feel fortunate to have found such an ideal replacement on specs so we share the news here for those needing the info later.

And Installed. Ryan 'the Pass' Passey did a nice fab job on some aluminum brackets to make the result clean and easy.

Original pump has gone a bit weak with wear, so we added a second of the same original Bosch intercooler pumps. Did that after looking at all the more powerful upgrades available, and decided instead on the redundancy of having two pumps in the system for more flow and was also the most cost effective choice.

As you can just barely see above, Rocky sneaked an oil cooler for extra protection and cooling.

Also upgraded the fan. The NC has just one 14 inch cooling fan. I already owned this 16 inch SPAL fan setup, it came off one of our dedicated track cars and makes a nice upgrade here and air can flow more cleanly through the nose and our various coolers and up through the fan and out our Singular vented hood. Moved the battery out of the way to passenger side ahead of brake unit (where normally there is container for window washer fluid but we took the wipers off this car years ago anyway!). Stock plastic fan at bottom of this entry for comparison.

With thanks to Mike at MotoEast for the tune work our supercharged 2007 turned TOP TIME OF DAY at the BMW Club Autocross yesterday...by more than 3 seconds! Amazing how cool the car runs now with the combination of cooling mods mentioned above plus E85, looking forward to Summer now!

Clutch Update.

Working on a new clutch with our friends at SpeedSport. Using an Exedy HD disc but adding a much improved pressure plate results in clamping force equal to the Carbon/Carbon setup but at lower cost. Why? The goal is to beat the ACT for price and clamping force and feel...at a lower price. This will NOT have a stock-like clutch pedal feel like the Carbon/Carbon does but hope to beat the ACT and give customers a clutch that can hold 300+ hp at the wheels at lower cost. Installing this week and will start thumping hard on it at SCCA event this weekend.

UDPATE!

Many YEARS of beating on this kit and it still rocks!

In fact, the very FIRST MP62 kit for NC MX5 just hit a new mark, 308 HP at the wheels!

Why does MOTOEAST Mike have that very satisfied looking smile?

Image

Because Mike just tuned the MOST Powerful 2.0 MP62 Supercharged Miata in the world...308 HORSEPOWER at the wheels!
Supercharged-MX5-300.jpg
We have seen peaky Rotrex 2.0 installs on E85 hit similar peaks but not with over 260 ft/lbs of torque like this beast makes! Notice it starts and finishes 210 ft/lbs of torque strong and is north of 250 ft/lbs of torque from 3000 through 6000 rpms. Still on the 5 speed transmission so we are packing a spare 6 speed figuring we might crush the trans pretty quick this weekend at Mazda Raceway Laguna Seca.

Most amazing that this is the FIRST NC MP62 install from 2007. Cosworth officials personally drove us the very first kit that year and we have been beating the snot out of it for 8 years! So this blower is far from tight and fresh at this point and it's a serious testament to the durability and reliability and ultimate expansion potential of our kit (link for kit details) that after eight years it can do over 300 at the wheels! Note this is still our standard 1.6 inch Max Power Header, not our 1.8 prototype we are still working on.

Previously did 262 HP at the wheels on pump gas and decided to make the switch to E85 to see what it could do on Corn and an updated tune from Mike of MotoEast. Added Mike's Big diameter intake, upgraded to thicker heat exchanger. This car using our RoadsterSport Max Power Combo exhaust...still our original 1.6 inch primary version. This is the best chart I have ever seen for this MP62 blower on the 2 liter motor and Mike did it with over 80F temps in the dyno room today and without maxing the timing. Mike figured from his experience that a few more degrees and the car could hit 325hp at the wheels.... but we are rushing out the door to Mazda Raceway Laguna Seca for fun this weekend and 300 is 'enough' for fun this weekend. :D
