Hi
Thanks for that. Which kind of car did you have the Rotrex on please? Did you have a stand alone ecu or piggyback, any intercooling.......and any occurrence of detonation?
Thanks a lot

2003VVT. I think he's been through at least 1, may be 2 engines already.....'Powercard'd', non-intercooled, trackdays = detonation.Thanks for that.

Hi Phil
But how much power was the 2003VVT pushing out? Kraftwerks USA state categorically that their 'base' Miata kit, which, on a powercard and without intercooling develops just under 160bhp at the rear wheels is good for track use. They reckon to have tested it with lots of track running.
There's a long thread on Miata.net about the Rotrex, with a lot of input from 949 Racing who are retailing the 'base' Miata kit (for $3200) which makes the Rotrex sound like a good proposition.
Thanks for the perspective on the M-tune rerouting kit which is also retailed by 949.

See from post 355 here: http://forum.miata.net/vb/showthread.php?t=286952&... It's happened with FFS kits as well, blown up EU engines. The OE ECU probably has more aggressive ignition timing. I've never been able to run a 'base' turbo/super kit with no change to ignition timing even though that what's claimed in the US.
.......ah! I see. You're speculating that the European OE ECU is different to the North American OE ECU, and that difference precludes running FI in Europe without the timing being retarded.
So......how about a Rotrex with Zeitronix wideband, Emerald ECU, coolant reroute, PWR radiator and, when they've finished developing it, a KraftwerksUSA intercooler? I realise this would no doubt require tuning on a rolling road but presumably Emerald have tuned loads of turbo-ed MX5s before.

That's the way to do it, If your going to that level of expense id personally be looking at a BEGI turbo kit or MP62 and going for 240hp with headroom for more, I can't see what the Rotrex offers over those 2 options.Edited by paul99 on Tuesday 19th January 10:23

Look at what happened with the Cosworth NC kit - there are certainly differences for different markets.I swapped a complete SC kit including EMB from a JDM car to a UK car of the same cc and year.
The fueling and timing maps were miles off IIRC something like 30% different in places.

I had it on a Golf Rallye - which has a huge intercooler as standard. I used the standard ECU, but it had a custom remap.
Great superchargers, but they are a bit Turbo like - unlike roots chargers or what-not.
