II'll apologize in advance if this has been discussed already, but I just checked out the 2007 RX-8 official press release and saw a link for concept cars. They showed the RX-EVOLV which looked like a regular RX-8 but featured a normally aspirated engine producing 280 hp at 10,000 rpm. Is this possibly a preview to the speed 8 or an entirely new car? I would buy this car tomorrow. With 280 hp, you would have similar power to the G-35's and 350Z's, and be pretty close to Evo's, WRX-STI's and mustangs as well. Not to mention the awesome looks and handling charasteristics of the RX-8. This boost in hp (if produced) would be a major selling point to people like me who were on the "fence".

that's old..i believe that pre-dates teh rx8...the rx8 was originaly supposed to have 280 hp..then they changed it to something like 250ish then 247...adn now teh 238 we have now.

now i'm sure someone who is more knowledgable will come along and correct me

True^

However, Speedsource is getting 260-265 hp with an internally stock Renesis so if you retuned the intake to rev higher, 280 could be possible! It doesn't mean it would be easy though.

army_rx8

^that's what i figuered....can the rx-8 get enough air to rev higher? I haven't really checked out what is possible or how much air the engine flows in the factory trim......so i suppose anythig nis possible..as long as we can get enough fuel and air in there

now where's richard with that supercharger. lol

Isn't Speedsource using a Motec?

rotarygod

Yup and a it's obviously tuned VERY well.

army_rx8

speedsource..they are running in st class?

rotary crazy

now will you belive that I saw a race car do 230 rwhp?

Im trying to find the magazine where Amemiya said they where making 220+rwhp on a street car with a reflash OEM ecu, but cant find it, if only I could read japanesse

the renesis is a very capable engine

I think Amemiya has an 8 with individual throttle bodies, but not sure if thats the one your talking about..

rotary crazy

I dint see the engine but it was a white car, I do remember they where making 221 rwhp with a reflash OEM ecu, and every bolt on Amemiya made including headers

rotarygod

OK we'll give you that one!

rotary crazy

Lmao

im sure with time we will see people in the 220 rwhp NA area, damn must people dint think this engine was capable of the 400 hp barrier, now we have several kits the will do that
