British 300HP RX8 launch
A 300Bhp version of the RX8 is to be launched in the UK before the years end. Most of the specifics are being kept under wraps till the unveling at the MPH show. All that can be said about it is that is a N/A machine. Hard to believe but apparently there is not a turbo or supercharger in sight.
I have been able to get hold of a press release from the guy who is putting this RX8 together for sale.
Quoted extract from his typed mail.
Can’t answer all your questions at this present time but here are a couple of facts that may be of interest to you.
Current RX-8 has 231 at the flywheel and 154 at the rear wheels,we have a Dyno print out on our vehicle of 300 at the flywheel and 210 at the rear wheels.Torque has been improved but not as much as we would like. Not a turbo (you can get those from Japan) or supercharged.
We should be in a position to come to the market in approx 2 months and hope to launch it at the MPH Show where we will have it on the T.W.White stand.
Retail price will be under £30k which will include a full Mazda Speed Body Kit.The car has been lowered by 30mm and the brakes have been uprated. The handling is better than the current RX-8 but I still need to sort out the warranty on this vehicle.
Neil White
For those of you who are not fimilar with Neil White owns a chain of Mazda dealers here in the UK... 4 in total i believe. He has taken it upon himself to produce a 300Bhp RX8 and a 260Bhp RX8 for sale to the general public. This differs slightly from going to buy an RX8 from a tuning house in that This car would be the same as going into your local dealer and buying a regular RX8, it even comes with a mazda approved 3yr warranty when it is finally released.
The question of how much MPG the new RX8 he is producing will consume was asked. To which Neil White kinda just skipped over the question. So i am guessing its not gonna be a very economical figure... But if it is as much fun to drive as the hype is makin it out to be... who cares :D

I find this hard to belive, esp with out any forced induction, it would have to be larger engine....more displacement (highly unlikely) or a 3 rotor, again unlikely. Not that you couldnt get 300hp out of the current rx8 motor, but it wouldnt be very streetable, and with the tighter emmissions already causing the hp raiting to go down in europe I dont see that happening....not that I wouldnt love it to be true.
That being said, if something like this were to happen, i would bet the UK would be a very likely place, because they have quite a few cars that have packages that you can get on the car, but are added after you buy it, so they can still sell it with the same emissions raiting and such.
Like the Evo FQ300, FQ400, Subaru STI packages, ect.
With the NB miata you could get a dealer installed turbo kit on them, it was included in the price of the car, but installed after purchase, so it doesnt affect tax, emissions, ect quite the same.
Will be interesting to see what hapens from this

Anyone remember a guy named Yenko? I believe this is very possible, 210 at the rear wheels is not much more that stock, but it would be a nice little improvement, although that is a big disparity from flywheel horsepower. It's nice to see though, that even dealers are getting in on improving performance.

300hp at the crank and 210 at the wheels? that's a sickenning amount of drivetrain loss..
I also have to doubt that it's possible on an NA engine. Now, I'm not saying 210 whp isnt possible as I've seen it done by retuning the engine, but i seriously doubt that the car is actually putting down 300 NA hp at the crank..
I guess we'll all have to wait and see.

I have strong reservations that he can improve those engine ratings without a turbo or supercharger and any additional forced induction unit.
The guy may own 4 or so Mazda Dealerships and being the Dealer Principal does not give him ANY authority to offer the original 3 year Mazda warranty.
Mazda Motors Europe (UK) would have to approve this car to be sold at any dealership and it would also have to have approval from MMC Japan to have their warranty.
Mazda Motors Australia (factory) head technical guru Alan Horsley developed an RX-8 turbo with MS body kits and even bonnet vents. This was a one of, and not for dealer or public sale. Just a promo and one of his pet projects.
He also developed 150 (NB) MX-5 Turbos (called MX-5 SP) in Australia for sale a year before the factory model. The amount of testing and liasing between Australia and Japan was/is very, very intense. He also developed in OZ 50 RX-7 (FD) with performance extras, this was called the RX-7 SP. He works for Mazda Oz and Japan.
I just cant see a retail dealer given approval to offer any MAZDA Warranty from new, for a heavily modified RX-8.

There is no way any car can be that inefficient unless it is lubricated with tar...

As for this story, I'll believe it when I see it. I don't know how they could get 300 at the crank, whithout a turbo when so many people have struggled to get close to those numbers with a turbo. If I read correctly, they claim to keep the upgrade very affordable, so an engine swap is out of the question.

Either way, if it's 15 horsepower more than that, I think it is still conceivable that you could have 300 at the crank and close to 210 at the wheels. I'm not saying that this is true in this case, but I believe it to be very possible nonetheless.

I knew I'd seen it somewhere. I totally agree with you that it is silly to have such enormous amounts of drivetrain loss, but by seeing that dyno, albeit on and AWD car, my point is pretty much proven. You'd be hard pressed to get numbers that great on a RWD platform, but maybe since it's being done at the dealer in house the engineering won't be so great? I'm not really all too sure.

the low dyno numbers have been discussed MANY many times
many people think the car goes into safe mode when the front wheels aren't turning and the rears are, resulting in lower power output on a dyno. Regardless, RX-8s are running times consistent with estimated bhp, yet dynoing way lower than one would expect - the M3 and the Porsche 911 both have the same problem due to their sophisticated electronics.
research it.
