yeah if it works for 06 it should work for 08, and he says the 06 one should be coming soon-ish...

VIsubi i dont really think you should spend money on an accessport if their kit is supplying a piggyback ecu... just tune it with that. but yes i too am awaiting the arrival of this kit.

I've been eye-ing it myself for about six months now, so I'm pretty interested in what you find out. I'd pretty much accepted the idea that the piggyback wouldn't work with my 08 and I'd have to figure something else out. I feel like a dog who's ears just perked up...

well Raptor says they've received significant inquiry for the 08 model. Maybe they'll make a plug-n-play harness thing to connect their ProSequential piggyback to our ECU... lets just wait and see.

Honestly I bet their problem with the 08+ is the lack of map data. Once RomRaider adds support for 08/09 5spd to their list I wouldn't doubt it if someone gets the kit and just has their setup installed by a shop to get pro-tuned. Personally I would love to get a super charger kit for my car.

yeah might be cheaper to order the kit without the piggyback and tune via tactrix. personally i bet they can get that piggyback working fine on our cars, and then itll be very simple.

Any of those cheap ebay ones will fit.

I dont think the Factory ECU can compensate for manifold pressures above atmosphere. I think the piggyback ECU is used particularly for that reason.

well significantly above atmosphere anyway but yes you might be right. good point. piggyback or bust it is then.

Yeah, but how significant are we talking? 3psi? 5psi? 12psi? Last I checked the Raptor Super Charger kit puts out "normal boost" 6psi psi and a "high boost" 9psi model. On earlier bolt-on turbo applications they needed a piggy-back because they couldn't re-tune the stock ECU like the 06+ models can.

those supercharger kits cost about the same as a full motor swap.

Except not everyone is interested in doing an engine swap. Personally I would like to do a supercharger to have something a little different then the norm. Besides, I'm pretty sure just the engine from a 2008 WRX alone would equal the cost of this kit.

I think were talking 1-2psi depending on barometer readings that day. If local conditions are high press (30.10in Hg for example) then you may exceed the ECU parameters before reaching 1 psi.

Also, keep in mind that the fueling tables are capped @ a load of 1.3g/rev so once you pass that you're ****ed royally without some other way to compute fueling and the other necessary parameters.

full motor swap is way more worth the price and will be more reliable than that kit. i wouldn't doubt it if that thing blew your motor. turbocharger>supercharger hence why most cars come with factory turbos and the ones that did come with superchargers now come with turbos instead; cobalt ss, mini cooper s, etc.

I'm pretty sure most people are aware that a turbo will produce more gains, be a similar financial cost, etc. On the other hand, not everybody wants to follow the trend...
And turbo's can be just as risky as what everyone here is discussing. Just yesterday I spoke with an STI owner who's turbo spiked and blew a hole in his engine.

youre giving him too much credit dzrt.

turbo > supercharger?

try to explain that one as a ZR1 rips you to shreds.

guys, turbos and supercharges are not equals s far as comparison. its not apples to apples. both have advantages and disadvantages. Someone should do both... that would be an engine management masterpiece if it were done successfully.

obviously im not saying superchargers are always better, but you cant just make a claim like turbochargers > superchargers. its stupid.

About using both, Volkswagon has used both. IIRC, they got a 1.3 litre engine to make 170hp without losing all of its low end torque. pretty impressive stuff.

ok so you spend $5 grand on this raptor supercharger kit for your stock motor and it puts out as much power as a stock wrx motor, then you can't tune it to put out anymore power safely. you spend $5 grand on a wrx motor swap and you can tune it to put out way more power reliably. way more practical to do a motor swap.

whered you get $5 grand tardo? its $4400 AU, about $2200 US (we dont have to pay this one tax which helps)

so its $2200 for a really easy to install kit which gives you similar hp to a stock wrx and more torque. so whats really more practical?

Jordan, I can direct you to the Raptor Superchargers guy (Tradewind over at RS25) if you dont believe me. He said $2200 or $2500 i cant remember. Either way much less than $3k.
