RX-8...The most beautiful car ever

You guys are funny. the frikin rx-8 is a 1.3 liter rotary, PUMPING OUT 250 SAE HP. Sheeesh guys, the engine, as stated by one of the engineers that designed the RENISIS, can handle boost. All that needs to happen is someone to get a quality kit for the car, and BUH BYE 350z.
 
oh im not disagreeing that the rotary is ****** sweet as engine, im just saying have fun working on it in the event something happens...or you end up with the situation again, where mazda stops selling a rotary engine based car like they did last time for 6 years, and watch the mechanics that know how or are willing to work on a rotary engine disappear.
 
You'll always have bragging rights with a 1.3 motor and 250 hp. Lets see the rest of those guys do that, since Honda owners always wanna brag abput hp per liter.

You are comparing apples to oranges. This is like comparing a motorcycle to a car. I'm sorry but you can not compare a piston engine to a rotary engine. Honda still makes the highest hp per liter which is in the S2000(120/liter USDM & 125/liter JDM). The compression for the RX8 to reach that 250hp is probably very high and I doubt you will be able to put much boost at all in that motor. You would have to machine down the rotor to relieve some of the compression first.

Ok, then I slap on the Greddy Twin Turbo Kit on the 350:D
 
I wasn't saying I knew for sure. THe normal compression to get that kind of power is 10:1 and up. But it's really only 9.2:1? Damn, where did they get the power from? That's pretty amazing. But it's 0-60 and 1/4mile time is still way slower than the S2000's.:D
 
s2000 is a smoking car for sure but I wouldn't buy anything from the Honda Dealership here in Raleigh. They are scumbags and that's being considerate....

The RX-8 is very different in it's intention than the s2000 IMO. The s2k is a roadster that hauls ass ideal for the enthusiast or mid-life crisis market. The RX-8 would appear to be an attempt at getting a market share by providing a sporty package with enough space to be somewhat practical. I just think the two aren't a great comparo. To many rotary fans it's a rebirth of rotary and that has a little selling power but mazda know's that is not how they are going to sell the bulk of the RX-8's.
 
Big_Ben, i know you said you wern't sure thats why I said "watch", sorry if i came off as a di#k. But you have to quit trying to compare a 4 seater with a two seater, its just like your apples and oranges debate with piston vs rotary. I would rather drive a 368 whp 2003 Miata for 23K. 190 hp/ liter

Eh.
Rotary engines can take a HELL of a lot of compression. They are tough as nails, and much more efficient. Only one out of 4 strokes in a piston engine delivers power. 3 out of 4 "strokes" (call them cycle stages, I guess) produces power. The power potential in a rotary engine far surpasses a piston engine, and power delivery is smoother.
A turbo'd RX-8 would smack the paint of a Z or a S2K (and I LOVE both of those cars). There are folks running 15psi on RX-7's daily.

WHOO HOO! Rotary really is a genius of an idea. If it werent for emissions/fuel consumption issues, they would be a lot more common. And the rotary is actually a longer-lasting design than piston engines, generally speaking. However I have to agree that finding a mechanic to work on them can be a problem. We have a Rotary shop in Indy that does great work.
 
you are limited in compression ratio because the angle on the rotor face's dish cannot be to sharp or the flame doesn't travel as well. Just bolt on a td-06 with a tial 50mm, plenty of room for a intercooler, should be able to put down 500BHP (415whp) mmmm i cant wait till mine comes... my race shop in San Diego just bought one from me :) So oyu'll be seeing it soon
 
The 13b was capable of enormous emounts of power. Mazda was using the 13b in their enduro cars tuned to about 600HP. Then somebody added another chamber and we got the 20b which could produce 400HP without forced induction.

The designers for the renesis were quoted in one of those magazines that the new rotary was built SPECIFICLY for boosted applications. Its tremendously strong and built to engineering fault tollerances that they could only dream of with the 13b.

I would not be at all suprised if we see an RX8 with some massive boost coming from some tuner shop anytime in the next few weeks.

Personally my problem with the car is its handling, not its engine. Until I get some real specs out of the front suspension and hear from the roadracers and autocrossers I'm going to stay away. But as is the car is great. The S2000 is just the better sports car right now.
 
I am in the rotary capital on east coast (northern VA), so no problem getting people working on it.

btw, all the performance tests done on the RX-8s may not be accurate at all, as early dyno results show the RX-8 ECU running a 'protective' mode for the first 20000 miles on the engine to allow proper break-in of the internals. The car should be NOTICEABLY faster after 20k miles.

The new RX8 is ugly in my opinion. First of all, it souldn't be a 4 seater. It is WAY too heavy.

3K lbs is "WAY too heavy"?

It's got 250 hp but the S2000 still beats it in every performance catagory.

You sure about that? The 1/4 mile tests are pretty equal...not sure about breaking, slalom, and skidpad tho. Post links if you have comparsions of the cars on the same track on the same day.

What's the deal? Mazda missed the mark with this one. Maybe they will do better with the 2 seater roadster version.

Nah, they did fine. It's a great car. I'd take an RX-8 over an s2K without thinking twice.

I completely agree. But like I said, the 2 seater roadster version will fix that.

I'm not 100% sure, but I am about 90% sure. I'll dig up a track test of the two, among other cars also. I think there was one done in Japan. I'll find it.
 
Now I don't want all of you to think I am bashing the RX8. The RX8 is an awesome car and probably the most hightech off all of those in that race. But in it's current form, it's no match for most other cars in it's class. When the 2 seater roadster version comes out that will ofcourse change.
 
i could care less about 2 seater roadsters if this is going to my only car (which it will be if i get it)

the utility of 2 usable rear seats is a great selling point to me.

it's a good compromise on performance to get just enough practicality in to make it a sensible yet still very fun drive.
