Is supercharging legal in the state of TX?

And where are we supposed to mount the front license plate?

Does porting + super/turbocharging balance out for the purpose of emissions testing?

super/turbocharging adversely affects exhaust emissions (though the Renesis is supposed to have a secondary exhaust re-funneled back to the combustion chamber to re-burn unused gas) but porting allows for more air intake so does this end up cancelling out?

Imagine porting + supercharging...

I believe I can fly... (just kidding)

I believe the engine is a very tight fit, and thus would be hard to adapt a super/turbo charger onto the car.

At least that's what I read. I think they will increase rotor width for the RX-7 to get upwards of 300 horses, so that they don't have to add a turbocharger. It seems better to me, as there's no better thing than a naturally aspirated throttle response Sure you don't get put back in your seats but the response is immediate all over the RPM range, specially in a rotary.

I'll just wait for the Mazdaspeed version available in a couple more years, I need time to save some loot...

if the 'speed version is anything less than 325hp, I may just go with 6-speed 250hp version, but all the possibilities and experimenting would be fun!

Keep in mind that a MazdaSpeed (or more likely for the RX-8, MPS) version would not only increase horsepower but lower weight by use of lighter materials.

So with a slight power boost and decent weight loss, there would be a great deal more speed to the car. I think that is the way Mazda will go instead of just upping the displacement a great deal. Probably increase rotor width a few mm, and get upwards of 300 horses and 200+ lb/ft of torque, so that car should fly

I'm sure they will also make suspension adjustments as well.

You betcha. Check out the "Boowana" forum for the answer sometime today.

What do you mean by that?

If properly tuned, no. And that "re-funneling" is the same as EGR, which piston engines are required to have also. Forced induction does not interfere or eliminate it.

damn you beat me sputnik. i had to register so i could give an answer. yea you can supercharge. we have 2 supercharged preludes in the club.

sputnik, is there going to be a rx8 club of dallas or anything? because i would like to meet up etc and get a ride in one of these cars if possible. please let me know.

thanks,

I'm sure that there will be at least an informal club in the DFW area. Heck, with Boowana and others in town, there should be a strong core of enthusiasts around here.

have you guys thought about working out something with the existing RX-7 Club there...

I am in the process of developing a structure for the Houston Club to change to a new format enveloping both platforms and accepting all future rotary or sportscar platforms.

RX - 8

i've been highly envolved in the rxx7 club in dfw...and i think it would be a great idea for all the new rotory owners to come and join us..we have a few non rotory people that hangout with us as well...including a turbo mazda mp3...a miata or 2....a vette and a 240sx...were pretty much like a huge family...cant wait till i can run my seven up next to an rx8..lots of fun
