Question for your custom bellhousing setup...
Do you think that you could run a stock Miata flywheel/pressure plate with a special disc and use the Miata stock release arm (maybe even the release bearing)?
Im thinking about a tex racing dog engagement transmission because Im thinking of blowing my budget out of the water and this would be one of my "to do" things.

Hey Bill,
Just stumbled across this thread. Been away from Miata Turbo forum for a while - never dawned on me that there would be such an extensive thread on an FP Miata.
I have a slightly converted SM (still has top) and a fresh tub on a rotisserie - so we are a long way off from your FP. Car ran as FP back in 05, but Regional Races (SARRC) only here in the SE. Finally getting back to working on my car. Will be asking bookoo questions if you don't mind.
First one echos Lennox60. My tub has no cage at this time. I noticed you went from a half width to full width main hoop. Was this done to reduce the number of bars stuck out in the wind?
Thanks for the detailed posts you've put up!

As for the cage, yes it was converted to a full width design to minimize surface area and drag.

Mr. Bill
thanks for that cam info.
Another question if you please. Are you still running the Stinger ecu the car came with? I'd previously read the whole thread and I thought you had changed to a Haltech along the way. I can't find that specific reference to verify what you've got at the moment.
I've been dicking around with an MS3 and can't seem to get it to work. Back in 05 I ran an AEM that worked well but we've been using MS 1 & 2 products in our shop with good results. I wanted to try the MS3 on the Prod car, but my total lack of progress may force me to have to just bite the bullet and switch my shock/suspension money into a commercial ecu. Do you know anyone in the Prod community that may be running a MS3?

Sorry I have not been on for a while, got the pics just need to upload them. As for ecm, I run a electromotive tec gt, it has been flawless. Jesse did the tune, very drivable on track, but the car does have a hard time at idle, not surprising with big over lap cams and light flywheel.

Nope, its a tube frame. And I have to add lots of lead as it weighs only 1680lbs. With the 2.3 MZR engine it makes lots of HP also. Its a Riley Grand AM chassis copy so its really torsionally stiff. I'll have no excuse if I don't win races with this one. And for those that are not diehard Mazda fans thats the 787B Lemans winning paint scheme.

The restrictor is called an SIR and caps the HP to around 280. Its 31mm. I was supprised in my first use of one to find they work pretty well. I had one on my old GT2 car that was 37mm and the car put down a stout 320 WHP. Whats suprising about that is that it had the non SIR cams in it that run much more overlap and still made good power. If you look at most Grand Am cars, the open cockpit cars will have them placed just over the drivers head.

With an SIR there are bell mouths at both ends that you do not see. And contrary to what you think might make sense, the small diameter is at the entrance and it tapers to some larger size slowly till the exit bellmouth to eliminate any turbulence. I was going to install it backwards at first the first time I installed one. Fluid dynamics is not my strong suit.
