i dont know where they saw 247 but ive seen 250 everywhere. and as i said b4 the rx-7 will have closer too 300 as reported by motor trend... and it will weigh 300 lbs less.... in other words 280 hp 2600-2700 lbs

Guys you have to remember cars performcae is not just about Hp but weight also. And the rx-8 is a few hundred pounds little the the new Z. Rx-8 about 3000 lb Right? Get a high flow cat and intake. It will get an extra 10 hp. An Ignition box box might sqeeze a few more and imporve fuel mileage.

Oh sorry 2600 to 2700 LB on 250+Hp sounds like it can kick so ass still
the new Z still floating around 3200..........so do the math 3200-2650=550 lb dawm that like having a sumo wrestler in you car |

And Bigtime- first off its only a downpipe if the car has a turbo. The most noticable gain that MazdaTrix has gotten on a N/A is to use the header and dual silencer/exaust combo, they did get about 35hp to the wheels, thats if you want to lay out over $1250 for thier system and figure out a way to wire your 6ports and also remove all your converters on the car. |
yeah its quite obviuos the rx-8 cant compete with the 350Z. itll run with a audi tt or boxster but thats about it. the 350z is just more performance oriented. mazda went soft on this one.

I head the 350z has liek a superlow emmisions and has no cats whatsoever

I know for a fact that a full exhaust will give more HP for a N/A rotary! I live in Denver, have a GSL-SE, my cousin drove the car up 4k feet to the mountains, we installed headers, replaced cat with test pipe, and ran straight pipe out the back (yes it is obnoxiously loud!) and the car is noticably faster, and far more torqey (sp?) that before, and that is 4000 feet higher in altitude. It will flat outrun my 97 N/A stock Eclipse, and before that was a close race. Also I don't think the Rx8 was really designed to run against the 350Z, the 350 is a 2 seater, the 8 is a 4 seater, it is better matched to cars like the Altima (4 seats, 240hp), IS300 (4 seats 220hp?) It is a 4 seat sports car, if they produce another 7 (please please please) that will be the comp for the 350Z. Just my $.02

Just a quick thought, so feel free to point and laugh...
A few years back, Mazda put an axial-flow turbine in for the turbocharger in one of their sedans. I have no idea which one, I left the article about it back home over the holidays in stead of bringing it to my folks' place. Most cars use a radial-flow turbine hard-mounted to a radial flow compressor, due to size and weight restrictions. Now, I haven't worked enough with radial-flow turbines, given what I do (jet engines for airplanes) to know offhand how that will do with a cat. But wouldn't that be a place to start for looking for a few hp? And yeah, I know that getting the mechanical power (rotation) from the turbine to the compressor spool will be a bitch-and-a-half. But hey, back then Mazda came up with a solution that can maybe get tweaked by somebody if we can find a manual for that other car. |
does anybody realize that the RX8 is just a family "sporty car"
if mazda wanted to make a performance car don't you think they'd make it have more power |
I think the best way for Mazda to get forced induction for the next 7 would be a supercharger, I have seen it done to 1st Gens with good results and it helps with both Torque and HP increase, and it is a linear increase in power that is more reliable than turbos.
