Well if this doesn't end all the naysayers about the engine having a larger displacement than 1.3L and making over 300 hp nothing will....this vid shows the test mule that the guy ws talking about earlier. I can get more pics if you need them

I actually figure 20% DT loss for the FC, FD and FE. Then number come out closer to the factory spec then... for example that 270 RWHP FD would have around 330-335 HP then

I just see some guy in a dark car flashing his private parts. That doesn't show me proof of anything other than he drives a 1990 corvette.

Sorry guys i told you wrong, Its not Motortrend, The article is in August Automobile magazine on Page 80. Motortrend basically has the same future performance cars that Automobile is covering, verified this when i went back to my barbershop and picked up the magazine again. I took phone pics of the info to... i am looking for a 3gp converter to show you the article. Or if your at your local news stand , you can see the mag there.

With technology getting better , Mazda could further upon the Renisis motor. Look at the current Renisis now, it makes 232HP in N/A form compared to its FD counterpart that made 255HP with TWIN TURBOS, not one turbo but two!

Thats 23HP more than our N/A rotary, and it used two turbos to get that 255HP goal.

And you guys really think Mazda couldn't give us a base line 300HP rotary? You guys are nuts or either you have a few brain cells that have died.


And as far as fuel econemy, what rotary that you know of gets good gas milage?
Its the nature of the beast......

We all know the RENESIS doesn't make 232, everyone is dynoing about 170-175 whp. With a 15% loss in power through the drivetrain that is 200-205 tops. The AP2 S2000 is SAE rated around 237 but they actually dyno around 210whp which translates back to 240.

Its safe to say the Renesis makes between 220-228BHP, as per the euro spec engines. I've seen on on an engine dyno and many folks who dyno'd the car themselves got in the mid 180's (including me). Not to mention all the dyno's with likely bad coil packs.

all the constenation over the actual HP numbers and the euro spec 228BHP number was right all along.

Most of the dynos I have seen are between 185 and 200whp. I thought it had been proven by some race teams around here there was a 13% drivetrain loss?

Speedsource commented as such a while back.

I seriously doubt that, unless the only criterion is drag-racing performance. FWIW.

well 185 RWHP at a 20% loss is 232 HP
but
202 RWHP at 13% loss is 232 HP at the fly wheel.

which one seems more correct?

20% loss or 13%?

and frankly it is pretty hard to imagine that the drive line of the FE is 7% more efficient than the FD.

222whp - 20% = 178whp
222whp - 13% = 193whp
---
232whp - 20% = 185whp

and so, how many people do you see with reports of 193 RWHP stock?

None... so it only goes to say that 13% driveline loss is unreasonable.

I was not making a point but just showing the numbers you provided were not correct.

So Mazda has given them all a mandatory vacation for a little while.

this halt on rotary work could be the basis for the rumor ash heard
Are you talking version or liters here?

There are plenty of people that have reported 190+whp.

And that ~13% figure has come from race teams that have dyno'd the car on a chassis dyno and the same engine on an engine dyno. they probably know more than you can assume.

I'm capable of making a lot of assumptions. In fact, I'm assuming I can assume more than those guys know.

another rx7 thread...yay.....

i hope it enevr returns, the FD is my favorite car and to bring it back it will destroy it. let it die and stay known as one of the best japanese sports cars ever.

why bring it back? make the next rc8 badass.

and 350hp from an n/a renesis from an oem? good luck with that!hahahaha

^ uh you're a little late to the party man. This "another rx7 thread" started over 6 weeks ago.

But, as much as I DO want another rx-7, it is kinda like movie sequels...You hope to god they live up to the prestige of the first or it will ruin the entire franchise. But hey, the FC was better than the original, and the FD was far superior to the FC. Mazda knows how important theri halo car is. They would NOT remake another rx-7 unless it was superior to the FD. Which I guess is why we are all having to wait so long.
