Feeler - 65mm or Bigger Billet T-Body
Hello,
John and I at M-Tuned.com have been talking about producing a Billet T-Body for the Mazda Miata. Probably start with a 1.8 version around 65mm. We plan on making the throttle a direct replacement which will use your Miata TPS and IAC sensors.
This items would be made out of a big chunk of Aluminum and would be a very trick piece. It has been proven time and time again in the Honda world that a large T-Body works wonders on a Turbo engine, and I am starting to see others playing with smoothing out the lips and ridges on their T-Bodys.
Would you be interested in this type of aftermarket piece? It would probably retail for $249-299.
Remember... Our T-Bodies are very small! 65mm would be a large increase in size.

Marc, I think this would be a great product but I doubt very many will sell, simply because we are all cheap bastards. I am sure you would sell a few, but the FI miata community loves to stay in the low boost range where you will not see any significant gains from such a mod as tb and/or bigger intake manifold.
I would probably go with one myself when the time comes, but I would pair it with a properly sized manifold and a built head, so it would really be a must have for me as the stock tb would be a restriction at that point in the power level I want to be at.
Definitively something you should carry I think, even if you only sell 20-30 per year.
Even though the price is very reasonable for a CNCd piece, I'd like to see it lower if at all possible. To state the obvious, many more people would be in on this if the price was much more affordable, lets say $150ish would be freaking awesome and I'd go for one sooner lol.
I think that you should be able to offer the same tb with a FM-type of spacer adapter for the 1.6 cars as well, and give them the option of having a 1.8 tps for their MS....just a thought.

I dont know if this will confuse the IAC with a standalone, but I can see why it would throw off the factory computer if running parallel.

The IAC bypasses x ammount of air when the throttle plate is closed, why would it matter what the diameter of the tb is when the only air that gets bipass is going through before the throttle plate...once the plate is open, the IAC is pretty much not doing anything, it could care less how big the plate behind the IAC inlet is, it just doesn't matter.
As long as the IAC inlet is the same as on the OEM tb, we should not have a difference in idle, and I think that is what Marc meant when he stated that we will reuse OEM TPS and IAC.
Please feel free to correct me if I'm wrong, but I reall don't see this as being all that complicated. All you are changing is the diameter of the tb opening, not the IAC vane geometry.

I don't see why everyone wants to see dyno graphs etc., it is comon knowledge in the tuning world that a bigger tb unleashes more power, it doesn't make it, but a 50mm tb is a restriction and by increasing the diameter and therefore flow, you will see gains, esp. on the top end. I don't care for any dyno graphs to show comparison between this and the stocker, I realize that the actuall gains will vary depending on the rest of my set up, boost level, etc. I'd much rather see M-Tuned save money in the development so they can pass the saving onto me then to spend it on dyno time and such to show you that it really does work. You should already know that it does work, there are no cons to a bigger tb.

Well I'm worried about where the power is going to come in at. There is a slight chance that if it's too big it may hurt low-end or even throttle response, but it should most definetely help with top end and i would assume bottom end as well. I don't think slapping car on the dyno should be a big deal for a company like m-tuned.
Sorry Brain...the screws being secure comment had to be made, suprised noone said it sooner.

Great to see some interest. I was off from my real job last week and visited the CNC guy with John on Thursday. The CNC guy is quite interested in making them and they are probably going to start with a non Miata market item first. After those will probably be the Miata T-Bodies.
