I'm thinking that might be 285 at the crank. Many of the SC units we are seeing are around 50 hp gain. That would put it at around 288 hp.

I would say Blitz might be the first true "mass" produced SC kit. You will get small outfits making their own units, but Blitz, Greddy, Apex, HKS, Vortech, Paxton, ATI, etc. are the companies I think of when you say mass produced. Of those I think only Blitz has a kit for us, though sunflower supposedly has an ATI unit they have on their RX8 car.

 

yep i think 285 is the crank. 240 whp i bet.

 

BAH! Need more power! Arr arr arr!

 

Racing Beat only has an engine dyno. Any numbers they quote are at the flywheel.

 

240 whp compared to the stock 170+whp? Come on, you'd probably take it if it was real.

 

Probably, but you gotta put things into perspective when you consider the cars I've driven and my enormous lust for rear end power :b

 

Not MazdaSpeed Japan!!!
Sound like the operation of MazdaSpeed US is not in conjunction with MazdaSpeed Japan.

I doubt MazdaSpeed Japan will ever talk about forced induction. As I post millions of time, the only player in Japan so far are:

Blitz - Compressor.
Phoenix power - using trust turbo.
Trust - similar development on turbo.
Knight sport - their own supercharger
RE Amemiya - Trust turbo in their AT 4 port Renesis.

I don't think I have missed any of them,....
No mention anywhere, in Videos, Option and Option 2 mag, RX-7 and RX-8 mag, RevSpeed in Japan EVER mention a Mazda made forced induction in Japan. So just stay cool please. Hope I clear THIS up once and FOR ALL!

Sorry, my serum crampy level is off the chart today :o

 

What's to clear up? They had one there. I don't care who made it, it was a Mazdaspeed car. Like I said, it doesn't mean they'll produce it.

 

Well if someone put an aftermarket forced induction in the car, although it has all the MazdaSpeed component available even in the MazdaSpeed JDM RX-8. It is still not a forced induction car from MazdaSpeed though.

Sounds like you put diamonds on a LV handbag and claim that LV made a diamond handbag. I rest my case :D

I have to clear up. There is no sight of the MazdaSpeed turbine available. Even so, Trust will be way ahead in the FI game in rotary car anyway

 

To me if MazdaSpeed US made a supercharged RX-8 will be equal as if Hymee put out a supercharge RX-8. Not a single difference to me what so ever. Anything that is not from Mazda Japan is AFTERMARKET. peroid.

I wonder what Hymee is up to?

 

Maybe Mazda will once again bring that Brilliant Blue FI car to SEMA for some more scrutiny. I plan on attending, and if it is there, I will get the whole story of its existence. This will be the fourth time that I know of it shows up in Vegas.

 

It wasn't just some car with a supercharger and a Mazdaspeed sticker sitting in the parking lot. It was in Mazda's showroom with their other cars. It is owned by them. The intercooler was way larger than they would ever use but regardless, it was their car.

 

why isn't anybody talking about better tuned engines for the 8 aside FI?
I remember reading somewhere that a mazda chief engineer said 'we can do anything with the renesis, increase displacement, increase number of rotors or turbocharge it'

What about a 3-rotor 8, like acosta motorsports made? I mean, ok, you don't have to reach extreme numbers (like the 900hp they claimed) but an engine like that, making 300-350hp, sounds pretty normal. and since rotaries don't survive turbos for long, why not follow the n/a way? longer engine life, insant throttle response with no lag...

Rotarygod any comments?

 

a 3 rotor renesis engine is impractical because of the port layout- specifically the siamesed exhaust ports. FI is a "simple" bolt on solution for people who already own the cars. increasing displacement, which by the way has been talked about on this forum many times at length, is not something the average owner with some hand tools can do himself. or even the above average owner. rotaries can and do survive turbos for long time periods with PROPER SIZING,TUNING AND COOLING. and modern turbos have nearly eliminated anything that could be considered lag. NA increases in power will come from porting polishing and engine management etc. not many people are as yet willing to crack their motors open for port work though and the ecu hasnt been an easy puppy to deal with.

 

maybe you're right. I just asked out of curiosity
so 250-260hp is the most you can make, choosing the n/a way (from our euro 231hp cars), right?

 

just my personal opinion based on what ive learned about things since coming to this forum and talking with experts but here goes- i think there is probably 30% more power left to find in porting and polishing, tuning and intake/intake manifold/header/exhaust mods. maybe slightly more. so if you take a base number at the wheels which i believe is correct- 190whp and add 30% on top of that its 190+57= 247whp. i believe that is an achievable, hopefully even street/emissions legal number. and hopefully not just at the peak but usable power all across the rpm range. now add your FI on to that..... muhahahahahaha and get a really nice MS suspension.

 

I just saw a coverage in the Option mag about Phoneix power trust turbo dyno at 350ps at crank. Boost is 0.8kg/cm ... what is it in psi?

They said they need 2 intercoolers for it and still high in water temp.

 

You left out 1 thing that makes EVERYTHING faster.. the V-Tec sticker!! OMG!

ok.. just kidding..

That sounds about right on the engine.. FI on top of that would be sweet.

 

11.3 Psi

 

oh thx :p

 

Phoenix's Power's RX-8 is pretty much unfinished. At least they have the time and money to experiment.

 

what? i had no idea anyone was even trying to develop a turbo for the AT

are there more details on this development? I thought the AT could not handle more HP, or was that just the 9,000 RPM redline that it couldn't handle?

 

There are videos in another thread that you can download... Let me try and find it.... It sounds pretty sweet..

Fo Shizzle Snizzle....

 

Sorry.. cant find it.. Anyone?

 

that would be great, thanks my nizzle :D
a good 50 HP boost would be fine by me
