The amount of time it takes to fine tune idle, cold start, and power maps to all run as smooth as OEM takes time even with a knowledgeable tuner.
what happens if someone uses a powercard on a turbo setup... does that invalidate your argument? cause im pretty sure we all here know that a turbo doesn't change cold-start issues. I'm willing to trade off 10-15hp here and these for compromises, but to trade off 50-60-70 rwtq because 30minutes to remove a turbo setup is too long, is kinda crazy. |

People go to a rotrex vs turbo for more reliability, less intrusive install. Up the a certain power level the piggyback follows the same philosophy. Turbos dont change cold start issues but I have yet to see a megasquirt have the same cold start characteristics as an oem ecu in a broad range of temperatures. They can get close, but not as good. The ones that get close to oem spend a good time fiddling with their cold start maps, something you dont need to do with a powercard. |
Wait. Since when have we had a stupidcharger forum?
|
Since turbocharging a track Miata means taking a second mortgage out on your house. Heck most of the turbo guys could by a turbo Porsche for what they have $$$$ into their Miata.

False. You can do a reliable 200hp all day long for not much more than a stupidcharger kit. Trying to make 300+ yeah, that might be a second mortgage.
Buy andrews kit for 5000. Profit. |

I still think they're going to sell a lot of these kits though, there is a market for this. And I have read the Rotrex kits in the past had good track reliability. No personal experience with them, but if that's true, that's a huge plus. |

I don't see 300+hp on any of those rotrex dynos either though...

I did Rotrex because it allowed me to keep my NA exhaust and it has the the least heat issues for F/I cars on track. Also I can reliably run stock long blocks and not worry about rods etc.
I'll be very curious to see if the trackspeed kit coming out increases the number of turbo track miatas... My guess is that 300 hp on track cars is going to make a lot of issues regardless of who/what makes the power. If I wanted a fast street car I'd go (FM2 Kit) turbo. |

SC, bracket and pulley system, oiling and cooling system etc? I'd like to reuse my megasquirt, injectors, etc. and do my own IC and piping set up to save some pennies. Gary TDR |

Why all the hating? The Rotrex has it's place in the Miata world. It's fantastic on the track. Dead nuts reliable. I can also see why it would accept more timing without turbine back pressure. FWIW I am also a turbo fan but prefer them on the street. On the track I like the razor sharp throttle response of the Rotrex. |
^and that dyno reads super low.

Yes. These were all stock motors. TDR has a track car with a fully built motor running MegaSquirt. They will be getting it dynoed ASAP.

But 180-200hp on a turbo reliably isn't that hard. You did it on a greddy kit on a 1.6 for years.
Yes, 300whp turbo cars are going to break stuff on track. |

Now it's reliable and can run non-stop in the heat. But it took 6 years to get there. |
Alright, maybe a greddy kit wasn't the best example. But log manifold+low boost+good cooling+inconel=fun.
