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.

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 know you hate m.net, so do you really want me to look up those threads?

Vlad, Emilio himself had many threads on m.net back in the day extolling the virtues of the Rotrex when the Kraftwerks kit first came out. He specifically said the Rotrex was allowing them to run more timing and more compression than would be typical for a turbo at that power level.

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.

Can you give me lessons? Make sure you're sitting in an armchair.

295whp with a C30-74, 99 built motor and E85. I wonder what the C30-94 would do?
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.

New build that has yet to hit the track in that config or is it currently running around on the track but has not been dyno tuned? If the former, in for results. If the latter, for shame.

Now it's reliable and can run non-stop in the heat. But it took 6 years to get there.
