Stock Renesis maxed out

Stock Renesis maxed out
I'm a VW guy looking at buying an RX8. My google searches have turned up nothing. I see a lot of guys running the RX8 in the mid 300whp range but they only list modifications such as Forced Induction but no 'engine' modications.
On the stock motor what is its truest potential? Assuming of course that tuning has been done properly.

I read that whole thread just now and it seems to only answer the question "How much power are you able to extract from an NA Renesis?"
My question is:
"How much power am I able to extract (via any means... N2O, Turbo, etc...) before the stock motor can no longer mechanically function?"

Hmmm... So am I correct in assuming that the guy running turbos and low psi are using stock motors and producing 300 whp all on a stock Renesis?
If so that's a good power number. I'm not pipe dreaming that these are producing 500whp or anything crazy but I abolutely can not envision buying a 'sports' car that can't produce a measly 300whp on a stock 'block'.

Personally I would just want to stay away from having to have any machine work done on the motor. If a person can upgrade Apex seals and push over 400whp that is awesome!

OK, so I can look at a long term plan of High power builds at least.
In the short term though: A T28 Turbo tuned properly on a stock Renesis should be able to produce reliable daily driven power in the 300whp range... correct?

But 300whp is 'relatively' easy to achieve and stable with a good turbo or supercharger. It's a lot more expensive and a lot more work to get a Renesis up to there then it is to get a Vdub or just about any other piston engine.

My very small 8 valve VW was putting down about 220whp, then I had a kill tune with nitrous that would put me around 280whp... That was a light fast car.
This is a part throttle run just hours after it's completetion. Due to unfortunate circumstances rust prevailed and took it's life rendering it unsafe for high speed racing (The drivers seat floor pan fell out and the drivers side strut tower scissored as well)
I am looking for a light weight replacement in the 10K range. The RX8 seems to fit that description. The VWs are nice looking but getting one to hook at 300whp is a task in itself.
Something RWD seems to fit the bill but driving a Z28 or another 300zxTT (Had 2 now) is just not my idea of fun anymore. A Supra would be nice but my budget is rendering that incapable.
I have a friend at works who trashes the RX8 like it's the worst thing the car world ever produced... He's a reliable source imo but I think all car in stages of infancy tend to get overlooked as a being unreliable when truthfully most people are just starting to figure out what they are capable of.

MM has also yet to let us in on his max HP with satan hairdryer turbo, although im not sure it would be near 500 he seems to beat around the bush on it being over 400.
its not that the poential is not there, its the lack of RnD; our small community can only do so much in comparison to almost a century of piston experience. Not only that but asking your VW to get 300hp is only 150 hp per liter, wheras 300hp in the rotary is almost 240hp per liter

Tailgaters beware
There ar a few turbo kits on here that make 330-370 rwhp and there is also a safer easier Pettit Supercharger that many people run 330 rwhp with about 220 rw lbs torque and with the SC the car gets to retain the factory redline of 9000. The turbo kits tend to die off at 7800 rpms on most kits but make 240-265 lbs or torque with the 330-370 hp. From what I've seen the people with the SC can run high 12's with a set of slicks or drag radials, the turbos I don't know, it seems like no one really drag races the turbo cars by the lack of quarter mile info.
Look up pettit racing rx-8 in youtube and you will see many of them running 13.4-13.5's on radials doing dainty launches to prevent wheel hop from 3500 rpms where the car makes no power, with slicks they could launch at 6500 which is what it takes to propel these cars out of the hole.
Take one for a test drive and you'll fall in love, I've had many faster cars including a Turbo Supra but none were as addicting as this.
I don't know what my HP is rigtht now but I pulled on a 2000-2003 lexus GS400 the other day and they make 300 hp and 325lbs torque, it even surprised me.

Great info from everyone, THANKS!
I think this is the direction I will head. I'm not looking to blow everyone away at every stop light.... I'm looking for a quality handling vehicle that can get up and go.
I know from a stock perspective this car wouldn't be my first choice but then again how many people out there are capable of being 'inventive' when they all drive the same car with the same bolt on modifications! hahahahaha
Anyway... I hope this will be the beginning of a long relationship between me, the Rotary motor and the community surrounding it.

I still have yet to see a reliable 400rwHP setup. The esmeril thread kinda went:
"414RWHP!!..rabble rabble rabble...rebuilding the engine...rabble rabble rabble... now shooting for 500RWHP"
Not saying it cant be done, but nobody is currently driving around 400RWHP turbo'ed Renesis with months of trouble free operation as such.
