I keep hearing about a 660hp RX8 - anyone?
I keep hearing from my wife's friend of a friend about their dad's 660 or so crank hp RX8 in Phoenix AZ.
Anyone heard anything? Is that much power possible or do you think it was an engine swap or turbo? maybe nitrous? I was under the impression the Renesis engine doesn't work with boost very well, but I have to admit my RX8 knowledge is lacking
Anyone hear of this car or the guy who has supposivly done it? Or is it just BS? He's not the type of guy to do the work himself so he probably paid a shop to do it
I'm not too familiar with the limits of the RX8 engine, but I was thinking 660 crank hp was pretty huge for a lightweight RX8

only in pr is there one that high. 20b swap with major upgrades. in puerto rico like i said before.
names rgonza on this site
real name is robert gonzolez
he a few other guys do those swaps alot down there.
as far as one in phenix... no.
anyone else know of a 20b swap in az?
other than that, we just reached 335 whp on the renesis with a mazsport turbo, thats with the spark failing, so we can get more maybe 390 or 400 pushing it.
by the way... search.
it just wouldnt have been complete

yeah I'm usually one of the first people to say search on other car forums that I'm a home member of, but I'm the newbie here and am digging thru threads as we speak.
20b, ok that gives me a clue on what would be needed

Haven't heard about a Phoenix RX-8 in particular...but 660 HP from the Renesis? Might be possible, but the engine would have the lifespan of a house fly.
Yea, the guys in PR are getting 500+ HP from their 3-rotors.

while the 20b is a rotary engine, the fact that they did an engine swap at all means it's not REALLY a "660 hp rx8" anymore. You could drop a viper engine in the rx-8 with twin turbos and say you now have a 1000 hp rx8.
As others have said, about 400 hp is our current max record. That record might be broken, but you're starting to talk about some serious money to exceed that power point, and who knows what the lifespan will be.

nobody said this guys wife's firends' friend's dad in AZ did a 20b swap. Maybe he has the Renesis going 660hp.. or maybe he has an RX8 that does 330 crank hp and he used the Multiply By 2 (and list crank ask wheel hp), street racer school of mathematics.

yeah it's not unlikely that this guy is stretching the truth a little, or doesn't quite understand how to approximate crank hp. There's a history of both him and his son bragging a little too far beyond what reality is. At this point I still don't know cause the guy for sure has money to throw around from what I hear. Anyway, thanks guys for putting up with this thread

I have a neighbor that goes to alot of dragstrips and he seen somebody move back the firewall and put in a v8 and drag the RX8. He said it was crazy and the guy was really old like 70 or 80. It cranked out somewhere around 700 hp.
This my friends is no longer an RX8.

politely ask him what he did to his car to get 660hp, and post it here. If it is "intake and exhaust", im going to laugh my a*ss off.

We consider our cars Rx-8,
For example when you install a 13B twin turbo engine to a Rx-3 or install on it a 20B
you still considering it a Rx-3................
Usually you call of the car by the style of the body not buy the engine..............
It's happens all days on the drag tracks they call a Mustang a Mustang no matter which engine they have installed. (one of our friends have a Mustang with a 20B)
all the people here call our cars Rx-8 but with a 20B. I don't
know how many of this are in the world but I just know only 3 of them the one from Marcos Acosta, rgonza and RX8PR.
And yes our cars (rgonza and mine) PASS emission test with the catalytic installed,
but the catalytic restric to much and we removed them. (we just need to make the
emission test one time per year and is not a big issue to find the test for a $10.00 extra of the normal cost). We can use our cars DAILY there is not a any problem of heat, etc etc.
with the Renesis we maked 398 hp at the wheel on the blue RX8 a year ago.............
but without good reliability, now rgonza is working on this car, the goal is to push
350-370 hp with good reliability, now he is using a Haltech ECU, this project is goin to be finished on the next weeks.

Manuel

When you say without good reliability with 398whp, is it the engine or the drivetrain, I would guess that the transmission would be the first to go. Am I correct? I think the renesis can take some good power.

on the blue Rx-8 the engine...................................
on the cars with 20B's we already broke the tranny in both cars rgonza and mine. rgonza is working on a adapter to install a g-force tranny in both cars.
With the Renesis we don't see problems with 400 hp with the tranny,
the problem with our 20B's it's the torque, 416 pounds..........and 525 hp.
rgonza runs more hp and torque than me, he is over 600 hp, he already broke the tranny 5 times.
What we're doin now is using the cars with 8 psi of boost and until now we're not braking the tranny. We would keep the car's with only 420 hp aprox until rgonza makes the adapter to use the g-force transmissions.

if you're not breaking the OE tranny then you're not really flogging it hard, they break pretty regularly with near-stock engines if pushed hard as anyone who road races one can testify too, moreso if you drag race with one ... even Mazdaspeed admits it's the weak link
