Grassroots Motorsports / Flyin Miata Turbo install party
I'm trying to avoid the dreaded pics-or-ban sentence, so here are some shots from the FMII turbo install for a Grassroots Motorsports magazine project. The story will appear in the October issue, but here's the cliffs notes version-
Keith Tanner and Bill Cardell installed an FMII Hydra kit under a tent in the infield of Road Atlanta during our Speedfest event at the Mitty. We started with a mostly stock 94 Miata; it made 113 horsepower on Friday. When we did the final tune Sunday morning, the car made 238 at about 11.5 pounds of boost. http://img.photobucket.com/albums/v4...a/IMG_1881.jpg We didn't use a garage or anything special; just four jackstands, tools, and a tent. http://img.photobucket.com/albums/v4...a/IMG_1887.jpg http://img.photobucket.com/albums/v4...a/IMG_2101.jpg http://img.photobucket.com/albums/v4...a/IMG_2235.jpg http://img.photobucket.com/albums/v4...a/IMG_3013.jpg I also posted an update on the Grassroots Motorsports page, click the link in my signature to be magically transported there. |

I'd keep those idiots away from your car. They don't know what they're doing. ;)

3000- 100hp / 170tq 4000- 150hp / 221tq 5000- 212hp / 223tq 6000- 238hp / 211tq 6800- 238hp / 187tq It feels like a very small Corvette. Lots of torque, and it doesn't run out of breath up top. |
240rwhp at 11.5psi on the 2560 at closer to sea level is nice.
|
So they install an FMII kit and these are the only pics you post? running some wires through the firewall and someone trying to figure out what the yellow ring-handled thing is at the back of the head?
3 piece downpipe? even 2 piece down pipes suck! Can they not get the measurements/jig right so they need to split it up? and whats the deal with it being polished? that's important. |
Looks like you went to BPM. Their dyno does read a little high.

Polished... That is the only way parts come when they come from Asia. Give them a break Paul ;). Gotta be a well put together kit if you can install it in a field under a tent. |
What is the car running for an exhaust? Still stock?

Hi Paul- nice to meet you. Axe to grind?
Time was a factor in the tune. We had to get the car back to the event, so 238 at the wheels on a mechanically stock 1994 Miata with less than an hour of dyno tuning seemed pretty damn alright to me. Bill feels that there's a lot more torque to be had in the lower parts of the graph, but the car pulls like a train until I push the clutch, so it hasn't been a priority for me to spend much more time on it since. Inferior tune? Maybe you're a better tuning ninja than Ed Senf and Bill Cardell, but I have some reservations about that, since I don't know you. (but you seem perfectly charming in an aggressive forum poster kind of way.) And yeah, those are probably all the pictures I'll post for now. This is a preview of a magazine article, not an internet build. -edit- The exhaust is the FM turbo single. I had (and still have, for sale cheap...) one of the $150 Volt exhausts, but it sucks. |

I'm going to guess that they do that so they can service almost any configuration by just changing the lower part (Swap cars, different cats etc).

I called FM for a replacement, but they actually had me send both half's of the DP back to their builder in Cali, whose fixing it for me (at an EXTREMELY reasonable price). They're even re-polishing it for free. Now that's good service. 2 :bigtu: for FM. C |

Begi's downpipe is also 2 piece and I hate that. PS. my car was tuned in less time than it took to drive from my home in Point Pleasant, NJ to the dyno in Delaware. That's on the street, while I was driving, by myself. |
Time of build and working conditions are impressive for those numbers.....
atleast for me, as that is the scenario I will be working in. |

And I think Paul has installed or removed everything he has with 4 jack stands or less and without a tent. And all of his tools fit in an old bag that he keeps in his trunk. Still a cool idea though, getting that all done at the event. |
Paul, you mean Jeremy? The hydra guy?
Oh and polished downpipe has a lower emissivity than flat black downpipe. it will radiate less heat. satisfied? |
Actually, I did use a tent when I swapped the motor and trans recently but to level the field a bit I used only 2 jack stands.
