As some of you know, I went and bought FFS last year. Been working on getting the kits back into production for the last 8 months.

Just wanted to let you folks know that we launched the online store today, and are accepting preorders for the supercharger kits, and are offering a 500 dollar discount right now.

Here's a video going over the kits and preorder information. The main site also has a pretty good description of the kit.

Looks great man, wish I was in the market currently but I'll tell everyone I know! This thing would be SICK on my DD 10ae. Maybe down the road!

 

Thanks man! LMK when you decide to pick one up before you place the order.

 

Out of anyone on the planet that i am aware of, you taking over from Tom makes me the happiest. I wish you the best in taking over this excellent product.

 

Thanks for the kind words! I'm going to do my best to offer the most reliable, easy to install, and enjoyable supercharger kits for Miata's. With many parts in production, I am hopeful that in a couple months, I'll be able to show pictures of all the production parts. I think they are going to look really good.

 

Just got our first casting samples! This has been a long time coming.

 

Looks great! Exciting!

 

We received our order of 100 castings from the foundry! Got them at the machine shops to be machined and then anodized.

 

Pat you are a legend doing all this! Love to see your updates. It's quiet around here but I hope you sell these things like hotcakes.

Also hope you find time to get the race car going soon!

 

Please tell me you're sending these out with a yo-yo in every order.

 

LOL. If you buy a kit, I'll 100% make sure it includes a yo-yo!

 

I tried to buy some Yo-yos off Tom and he would never sell me any. Even asked in person when we were both at The Mitty at Road Atlanta 12-13 years ago.

 

We made an update to the throttle bracket assembly to make it simpler, more reliable, and improve throttle linearity.

 

Here's a YouTube short showing the blower assembly with our new EGR Support Bracket, Updated E-cool Fuel Rail, and heavy duty throttle bracket.


We are shipping the blower fully assembled as shown in the video! These are now easier to install. In addition, we are vacuum leak testing every unit to ensure the assembly you receive is good to go.

 

I installed a Fast Forward Superchargers kit on my 10AE! Running 10psi boost. Put a little over 50 miles on it so far. It drives great and everything is working well.

This kit has several improvements and I'm happy with how it turned out. The CAI seems to work well and looks good, EGR bracket is solid, pedal feel is great, E-cool with a modern injector and dedicated fuel rail is working well. I spent a year refining this kit and am happy that it's all come together.

 

How much do the short/long term fuel trims move around with the manifold change? I bypassed my VTCS on an otherwise stock 2001 and found fuel trim at +20% when VTCS was supposed to be restricting airflow, didn't drive super smooth in those cells either. Not that the switch between VTCS On and Off is particularity smooth as factory designed. I realize the 10AE has VICS but assume there's a change in estimated air flow versus actual with the supercharger.

How is tip-in handled? Power-card system tricks the O2 input to the PCM into reporting lean, adding fuel, when under boost? Essentially like driving with no AE function if you're tipping in and out of boost? Or is it entirely stock until boost where the stock injectors still work as stock and the 5th injector adds all the extra required fuel?

 

I'll have to check on the trims, I'm not sure. I don't expect they change much on the 99. Like you say, the VTCS is what it is with Mazdas control. But either way, the car still uses the MAF for primary fueling.

The stock ECU handles all the fueling when not in boost. So it's the same as it's always been.

When in boost, we add fuel with the main injectors, as well as with the E-cool. You could add it all with E-cool, but having the hardware in place for both is better and allows us more headroom in the fuel system since we control 5 injectors not 1.

 

I did not know that. Very nice!

 

Thanks for the clarity. The whole "stock ECU" thing is very interesting to me. So long as you're below the lean/rich code thresholds it really doesn't matter and the MAF and O2 will just mess with the trims to compensate as you described. As a principle I hate seeing cars outside the +/-10% rule of thumb but if it works it works, and who knows it may be within that window. Obviously if it got a CARB EO the fueling can't be in left field, IIRC the kit is CARB EO approved 90-03? Having driven an old FM/Begi Ubercharger setup I think the supercharger is pretty cool.



EDIT: Just out of curiosity - the whole 5th injector/evaporative cooling setup got hate, quite loudly, from some. You seem quite knowledgeable - and you bought FFS. Is this mostly a "it works at this power level so who cares" situation? The Ubercharger setup is a PITA due to, in my opinion, terrible QC and general lack-luster design. This seems much more thought out -except- the lack of intercooler. Most of what I read from FFS over the years was "yeah but it works". What do you consider the practical limitations of this? You have a stock ECU at idle, and this has to represent some sort of hindrance to peak output. And IATs probably aren't as cool as a dedicated intercooler. But it seems to work? Is that the long and short of the FFS model? Good for a stock motor, basically install and drive it?

 

Correct, CARB approved 90-03. We ALMOST made the 04-05, just barely missed one value. If we had installed a new cat on that car before, it would have passed no problem.

A great thing about these kits, if you run them as designed, they just work. We have several customers who have run their kits for 10, 15, even 20 years. Some have put over 100k miles on their stock motors with our kit. 5 minute belt change every 50k miles. As far as forced induction kits go for miata's, FFS is the definition of install and drive.

The E-cool setup has it's pros/cons.

The pros are it's simple. You connect two wires to it and hook up a fuel hose. No intercooler, piping, electric water pump, water, heat exchanger blocking airflow, etc. Very simple. And for the group of people who appreciate simple/reliable and not max power, it's great. It also keeps weight down. Adding air/air or water/air would add more weight over the nose of the car. This setup weighs like 1 or 2 pounds tops. And it keeps the throttled volume really low, so it idles and drives as well as a stock Miata. Air/air intercooled supercharged setups suffer from higher throttled volume. And we use E-cool to double the stock fuel systems size, so running a lot more boost on the stock ECU/injectors is now possible. Our kits run 10psi out the box, but are capable of much more.

Downside is that cooling power is limited compared to an intercooler. On 91 octane on a 01+ motor, 10-12 psi is all it's good for. Now lower compression and 93 octane? They have more potential for higher boost and more power. Or add water/meth. Or run E85 and now you can make as much power as you want. We have some people making 260-280whp on stock motors with E85, and a few running built motors over 300whp on E85.

One thing that has improved, we switched to the 6th gen Eaton TVS900 supercharger. The huge benefit on the TVS900 is they are wayyyy more efficient. So when you run higher RPM and higher boost, the MP62's efficiency falls off a cliff and blows a lot of hot air. All our kits now ship with the TVS900 which maintains higher efficiency, lower charge air temps, and as you push the revs and boost, they maintain their higher efficiency much better than the older generation MP62s. This makes a big difference for folks who want to make more power or track their cars.

Could we have put an intercooler core in the intake manifold? Maybe. But it would be more complex, heavier, and more expensive.

Later in 2026, I plan to put a built motor in my 10AE, and find the limits of the FFS setup on 93 octane and E85.
