Can I run this and remove the factory one for both NASA and SCCA for my 1995 Spec Miata?

It is my understanding that the adjustable FPR in the pic is now legal in both SCCA and NASA. You might want to consider securing it a bit better. It should really help your '95. Looking forward to hearing about the MSR-H race.

Neat. Did you buy it as a kit or put it
together yourself? Cost? I need it on my 94!

Thanks

Nice install, I like the whole set up. Remember to get a AF gauge installed in the car, running less fuel pressure between cold and hot conditions may require some tweaking at the track.
Just some insight from someone that has lost a few engines before running one in all my cars.

I agree. I have the innovate motorsport unit running so I can adjust accordingly.

Advanced Autosports has the NA regulator system figured out. Nice gains in 1.6 and 1.8 cars.

I am waiting to hear back from suppliers on prices and availabilty of parts. I hope to have answers within a few days.

I will post a classified add on http://www.mazdaracers.com when I have everything finalized

I know for a fact the 1.6L did gain power and there is no need to screw with the MAF anymore. My 95 is very promising and with less weight in the NASA series, that is a plus. The sad part, I lost 40 lbs in the last year, and I have to loose more now!

What kind of gains on the 1.6? Comparable to AFM adjustments?

The power curve is more stable, the Torque is better. Safe to say 1-2hp/1-2tq over the normal AFM clicking.

The main problem that most of the 1.6's will have is heat soaking, as the race goes on IAT will increase and the car will actually need less fuel to maintain the good HP #'s, where as the 96-97 NB cars use OBDII so the AF stays pretty consistent with the updated computer system.

In addition if it is colder out then when you dynoed and set your FP regulator / AF, for the 1.6, it will be a little too lean, the colder air will demand more fuel.

^^^^^^^ What he said...lol

3 hp is there as well!

We have a NASA race in Houston at MSR, and we will get to see the 99 with old restrictor vs the 1.6 and my 95 1.8 with the AFPR. This will be a good test for us.

I built my own with parts from Summit and the local hardware store. It was very easy and not too expensive. I have a small manual PSI gauge on the regulator and an electronic PSI gauge in the car. I already had a tuned AFM in my 1.6 and did not make a large difference at the dyno but nice to have the ability to tune when the weather changes. I would guess that the 94 - 97 will see a greater gain.

Bill,

Great solution to get rid of the factory fuel regulator with the fule rail adaptor. I have not had a chance to install the new FPR on my 93 so I will run it as is until I get the parts and time to install. I sent you a PM on your website, see you this weekend.

Newt, you racing again or supporting your MiniMe? Would be great to see you back in the car again [Smile] On second thought, you're too fast, just keep helping your daughter. Hope you make it to TWS in March.

If I can get up early enough I am planning on being there by 11:00. That is assuming I do not forget to choke my Fifth wheel toy hauler before I disconnect from truck! Again! Just imagine what a 14K lbs trailer can do to the bed of a brand new truck.....

Which pressure regulater did you buy from summit. There are alot to choose from. What pressure range are we looking for?

On pressure range Drago has this ad. So 52/54 depending on gauge.

I think Wheeler with his reg. was saying 55. YMMV.
J~


edit...
took out link, but the 52/54 is on 99/00 cars. On same gauge 54/55 on 96/97 car and about 38 on 94/95

5X Racing also has the NA regulators figured out, already track tested and proven! While the project is still in skunk works status, I won't spill too many beans here. I as well will post a classified when they are ready.

Cliffy is right though, you MUST look into an Innovate Air/Fuel Ratio set-up for your car to realize what adjusting your fuel pressure is doing to your mixture. Too lean is no good. He knows what he's talking about, trust him! We use the Innovate Motorsports LC-1 kit, it's worked well on our cars for years.

John has alot of goodies over at 5X racing, neat thing about the LC-1 is it works with all data loggers with the 5v reference out, I personally use Traqmate, pretty cool to see on the graph what IAT's do to the A/F ratio on the 1.6's. Ever watch what A/F does when you start to starve for oil, Took me twice to figure it out [banghead] , 3rd times a charm - saved the motor & head. [thumbsup]
